Full textAbstract:
Since the beginning of history, human beings have made great advances in technology. In the field of architecture, this movement has had reflections such as new construction and application techniques and the use of different materials. In parallel with this rapid progress in building and construction technology, solutions that meet the changing needs in architectural design have started to be offered. Aim: The aim of the research is to find out which plan type is the most preferred in terms of design in high-rise office buildings in Eskişehir road region, which attracts attention with its office building stock in Ankara, and to analyze the relationship of this plan type preference with the building's height and current value parameters. Method: Tracing method was used to find the ratio of plan types in the examined office buildings and to establish the relationship of these plan types with height and m2 current value. Then the obtained data were evaluated statistically and regression values were found by using regression analysis method. Results: In the 12 office structures examined in the study, open office (47%), mixed office (27%), closed (13%) and co-working offices (13%) were preferred, respectively. 66% of the multi-storey office buildings in the sample space of the research have a height of 100 m or more. Closed offices are the lowest value in terms of market value and mixed offices are the highest valued. Conclusion: It is understood that open-plan offices are preferred in the Ankara Eskişehir road region. As a result of the study, it has been revealed that these plan types, which are mostly used in office buildings, have a directly proportional relationship with the concept of current value per m2, but not with the height of the multi-storey building. In this respect, it is possible to say that architectural design decisions directly affect the real estate market of the country and this interaction has formed an important relationship with the country's economy by shaping the capital market.

Abstract High-rise office buildings are naturally energy-intensive as energy is required in large quantities to run modern building services and to power equipment needed for a hitch-free operation of the buildings. It was found in studied literature that maintaining good indoor environmental quality through air-conditioning, lighting and powering of office equipment contribute the most to an office building’s total energy consumption. Hence, over time, various strategies have been employed to reduce the intense energy demand in high-rise office buildings. This paper adopted the use of both literature review and case study methods. The paper identifies the key energy efficiency strategies that have been successfully deployed in high-rise office buildings using the literature review approach. Also, case studies were conducted on three relatively new high-rise office buildings in Lagos, Nigeria by evaluating them against the background of the best practices in energy efficiency. The study found that deployment of energy efficiency strategies in high-rise office buildings in the study area is still very low especially in the areas of building orientation, building envelope design and the use of renewable energy. However, the use of day-lighting techniques and sustainable lighting systems are quite prominent in the office buildings studied. The study underscores the need to make high-rise office buildings more sustainable through energy efficiency strategies across the whole building life cycle of design, construction, use and end of life.

Full textAbstract:
Social progress and economic development has resulted in the need to focus on the impacts of building microenvironment on the energy consumption in office buildings. The concept of a building’s microenvironment was introduced to understand the local microclimate around a building that is formed by the surrounding urban green spaces, the distribution of roads, and building proximity. For this research, we adopted a regression analysis to quantify the impacts of building microenvironment on energy consumption in office buildings. Taking the government office buildings of Guangdong Province as an example, we measured the building microenvironment through the urban green space density, road density, and number of points of interest (POI) around the buildings. The results showed that when the green space density increased by one unit, the energy consumption in government office buildings was reduced by 0.277%. Moreover, an increase of 1% in road density and in the number of POI increased the energy consumption in government office buildings by 0.288% and 0.048%, respectively. Furthermore, we discussed the heterogeneous impacts of building microenvironment on the energy consumption in government office buildings at varying scale levels. Green space and road density had less impact on the energy consumption in larger buildings, whereas the number of POI had no significant impact on small-scale buildings but did have a significant impact on large-scale buildings. There were also some limitations in the study. The data were limited to government office buildings, and did not include panel data, as well as it lacked building characteristics such as orientation, floor height, and building materials. In addition, it was impossible to evaluate the impacts of meteorological factors such as wind speed and thermal radiation on energy consumption in buildings. Nonetheless, our study demonstrates that energy-aware urban planning and design have the potential to unlock energy efficiency for cities worldwide.

Abstract Introduction Building-related symptoms (BRSs) have emerged as an occupational and environmental health issue since the early 1970s. Office environment maintenance may differ according to the total floor area of a building, i.e., the scale of the building. Methods In this report, we examined the association between BRSs and the suspended particles, chemicals, and airborne microorganisms in air-conditioned office buildings. The surveys were conducted from January 2018 to March 2020 in 27 offices with 333 employees and in 25 offices with 342 employees during winter and summer, respectively. The office buildings were categorized into small buildings (<2000 m2, 11 offices with 96 employees during winter; 10 offices with 91 employees during summer), middle-sized buildings (2000–3000 m2, 7 offices with 145 employees; 7 offices with 158 employees), and large buildings (≥3000 m2, 9 offices with 92 employees; 8 offices with 93 employees) during winter and summer, respectively. Results Significant associations between BRSs and the suspended particles, chemicals, and airborne microorganisms were few in small buildings. Although significant associations between BRSs and suspended particles, aldehydes, volatile organic compounds, fungi, and bacteria were observed in middle-sized and large buildings during both seasons, as a whole, those concentrations did not exceed indoor air quality guidelines, suggesting being of no toxicological significance. However, the results suggested the possibility of the effects of the combined exposure to multiple aldehydes on upper respiratory symptoms. Discussion and conclusion Our data suggests that further research on the total health risk due to multiple low-level indoor pollutants is required.

The topic of the paper is determining the impact of an epidemic threat situation on the design of office space and office buildings. The types of actions taken to improve safety are: procedural actions, modifications of technical solutions: architectural and installation and remote work. Solutions in the field of office space architecture include: reducing the density of occupants, introducing partitions, eliminating multi-person offices, using materials that are easy to disinfect and clean, opening windows and installing personal protective equipment dispensers. The installation solutions include air quality improvement, filtration and disinfection systems as well as telecommunication installation systems supervising the use of the building. It can be expected that in the future, technical solutions will be introduced into the designs of buildings and office spaces, which will be a place for meetings, spontaneous interactions, mutual inspiration of employees and strengthening their identification with the employer whereas the ratio of office work places will be lower. The structure of the building is likely to change to a richer commertial part, a co-working part and flexible offices, and a traditional part of office space for lease, but as such office buildings will still be needed.

Full textAbstract:
Surakarta is a city that has 54 villages/wards spreading across five sub-districts, namely: Pasar Kliwon, Jebres, Banjarsari, Laweyan, and Serengan. The buildings of ward offices in Surakarta are fascinating because they are some of the works of human culture influenced by local culture. The Joyosuran Ward Office building is Joglo, a strong Javanese nuance intended as a sign of Solo city's distinctive identity. On average, pendapa at ward offices is glass-walled and appears open with two doors at the front and the back. The function of a ward pendapa is as a meeting space, village gatherings, and other meetings. The next building is the office. The style of the ward office building in Surakarta is colonial architecture, a term for buildings with a form (or outside impression) of Nusantara's (Indonesian) architecture and modern architecture adapted to the climate, building materials, and technology developed at the current time. This research aims to find out the functions, elements of the form, and space fillers of the Joyosuran Ward Office in Surakarta. The research method used in this research is an analysis method with an interior design approach conducted at Joyosuran Ward Office in Surakarta. Data collected from informants, literature, and objects/artifacts. The results show that the functions, elements of form, and space fillers of the Joyosuran Ward Office are a public service office under the lowest government level management. The buildings are a mixture of colonial and Javanese styles. The benefits of this research's results can be an essential source of information for the development of interior design studies and cultured public buildings

Purpose This paper aims to fulfill the gap in existing knowledge of determinants of pro-environmental behavior (PEB) in the workplace and the influence of sustainability certificates on occupants’ PEBs in workplace settings. Design/methodology/approach A questionnaire survey with a total of 95 respondents from both certified and noncertified office buildings was conducted. Two independent sample comparisons were executed to understand the influence of sustainable building certificates on occupants’ environmental values, beliefs, awareness and PEBs. Findings Ecocentric value, belief and awareness were found as the predictors of pro-environmental workplace behavior. Certified office occupants showed higher awareness about buildings’ environmentally oriented characteristics. Despite higher awareness, certified office occupants revealed less PEB compared to those who work in noncertified office buildings. Originality/value This study determined the influencing factors on PEBs in workplaces and PEB differences between certified and noncertified building occupants. Less PEBs of occupants in certified offices signify the misperception of individuals about sustainable buildings and the need for more informative training about sustainability issues in the society. This result also draws academic attention to sustainable building evaluation practices and provides certain insights for more occupant integrated evaluation alternative for sustainable buildings.

Thermal comfort in office buildings is instrumental in improving the productivity of employees while maintaining their health. The primary objectives of this research were to analyze the comfort temperature in Japanese office buildings and investigate its relationship with outdoor air temperature. Additionally, we examined the differences in comfort temperatures with respect to closed and opened windows to factor in the increase in the opening of windows during the COVID-19 pandemic when air-conditioning systems were operated. We investigated the environmental conditions of office buildings and the thermal comfort of the occupants through monthly visits to each office building over a year. Field data were collected from four office buildings located in Nagasaki City, with 1047 votes obtained from 143 participants. The survey indicated that the occupants were highly satisfied with the thermal environment in their offices. The correlation between indoor comfort temperature and outdoor temperature was high in the FR mode. Based on the analysis, we developed an adaptive model for office buildings in Nagasaki City and compared it with existing adaptive models used for buildings in other regions of Japan. The proposed model is useful for energy-saving designs that bring out human adaptive capacity.

Abstract The city of Jakarta is the 7th big city in the world that has the most high-rise buildings. High-rise buildings in Jakarta were built from 1971 until now and in the 90s it was the peak of the construction of high-rise buildings such as offices and apartment. Tall Buildings with glass facade, concentrating plans are the most typology of office high-rise buildings in Jakarta. Buildings with the dominance of glass facade that reflect heat cause an increase in temperature in the microclimate and a decrease in building performance resulting in the amount of energy used by buildings, especially air conditioners. Building facade play an important role in reducing the improvement of the microclimate and energy use in buildings. Therefore, an analysis was carried out on the BRI II building on Jalan Sudirman Jakarta as a case study that represents the typology of the most office buildings in Jakarta. It turns out that this building has a high OTTV (Overall Thermal Transfer Value) value, so the largest AC cooling load comes from the building casing. Therefore, facade retrofit is one of the alternatives that can be done to reduce energy use, especially air conditioning. After that, a simulation of the casing retrofit to obtain a significant retrofit action can reduce the AC energy used through ottv value reduction analysis.

As Malaysia continues to develop at a fast pace, the number of buildings in this country rapidly increases. Commercial buildings which include office buildings are one of the three major energy consuming sectors, which includes industrial and transportation sectors. Most Malaysian government office buildings tend to consume energy inefficiently due to lack of energy optimization. This study aims to analyse the energy performance as well as the factors that influence energy consumption in government office buildings. The chosen buildings for this case study are six government office buildings located in Kuala Lumpur, the capital of Malaysia. In this study, literature review has been conducted on the common factors affecting energy consumption in office buildings. The energy consumption data of the buildings were collected and analysed by comparison among the buildings and the SketchUp software. The Building Energy Intensity (BEI) of each building was also calculated using the formula in MS 1525:2019. Literature review and results from the case study show that air-conditioning system is the major energy consumer in office buildings, followed by lighting system while other office equipment consumed the least energy. The findings also highlight that energy consumption in office buildings is affected by non-design factors such as building occupants’ behaviour, number of building occupants, outdoor temperature as well as passive design factors such as building orientation and window-to-wall ratio. Recommendations were derived based on the findings from literature review and the case study for best practices to optimize energy consumption in government office buildings in Malaysia.

Purpose The built environment is a major source of carbon emissions. However, 80 per cent of the damage arises through the operational phase of a building’s life. Office buildings are the most significant building type in terms of emission-reduction potential. Yet, little research has been undertaken to examine the barriers faced by building operators in transitioning to a green operation of the office buildings in their care. This study aims to identify those barriers. Design/methodology/approach Building facilities managers with between 7 and 25 years’ experience in operating primarily Melbourne high-rise office buildings were interviewed. The sample was taken from LinkedIn connections, with ten agreeing to participate in semi-structured interviews – out of the 17 invitations sent out. Interview comments were recorded, coded and categorised to identify the barriers sought by this study. Findings Seven categories of barriers to effecting green operation of office buildings were extracted. These were financial, owner-related, tenant-related, technological, regulatory, architectural and stakeholder interest conflicts. Difficulties identifying green operation strategies that improved cost performance or return on investment of buildings was the major barrier. Practical implications Government, policymakers and facilities managers themselves have been struggling with how to catalyse a green transition in the operation of office buildings. By identifying the barriers standing in the way, this study provides a concrete point of departure from which remedial strategies and policies may be formulated and put into effect. Originality/value The uptake of green operation of office buildings has been extremely slow. Though barriers have been hypothesised in earlier works, this is the first study, to the best of the authors’ knowledge, that categorically identifies and tabulates the barriers that stand in the way of improving the green operational performance of office buildings, drawing on the direct knowledge of facilities experts.

Abstract- Many of high-rise office buildings in Indonesia applies efficiency and effectivity of building form, cost, and time for construction as a number one priority. As a result, high-rise office buildings appears with a minimum-articulated form, and show the dominance by using glass materials as a facade. However, there are also high-rise office buildings that have an articulated form and its facades that are not dominated by glass, although they appear in small numbers. Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti Surabaya are one of them. Moreover, both buildings were designed by foreign architect, Paul Rudolph. Based on the potentials of both buildings, this research focused on Paul Rudolph’s principles in designing high-rise office buildings in Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti SurabayaLooking at the phenomena of high-rise office buildings in Indonesia as described earlier, this small number and the articulated form of high-rise office buildings designed by Paul Rudolph in Indonesia are interesting to be understood even more. The main purpose of this research is to reveal the relationship between Paul Rudolph’s design principles with buildings, which are Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti Surabaya. Using an interpretative method in a qualitative research, this research utilized theories that helps understanding of an office building, theories that related to Paul Rudolph’s background and common thought about architecture, and also Paul Rudolph’s theory about determinants of architectural form as a literature study. Building’s Anatomy Theory is used as a surgical tool to disect the study cases, which happens to be Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti Surabaya.Result of this research are six points of Paul Rudolph’s principles in designing high-rise office building which are: repetition, space, scale, rotation, light, and context. Implementation of Paul Rudolph’s design principles in both study cases can be seen in the dominance of rotation and repetition of building elements. The application of these two principles can fulfill all the three aspects of Paul Rudolph’s design ideal, which are form, context, and cycle.Benefit of this research is to enrich architectural vocabulary about design principles of a high-rise office buildings in Indonesia for the concerned educational institution, as a consideration and input to architects and the stakeholders to be more sensitive and critical in designing high-rise buildings in Indonesia, as a reference and study case about design principles of a high-rise office buildings for students, academics, architects, and the public with the focus of study concerned, and enrich the knowledge about Paul Rudolph’s design principles especially in designing high-rise office buildings in Indonesia for researcher.

During the 19th century, the most renowned architects considered a permanent presence on the site of their larger construction projects necessary. Some of them even maintained several on-site offices close to their construction sites, where architects and designers were contracted for the duration of the construction. This study presents two on-site offices in detail (office of the Palace of Justice and the Parliament Building) while outlining a further four examples in Budapest (office of the Parish Church of Lipótváros, the Ministry of Agriculture, the enlargement of the Royal Palace and the Technical University).There were three practices used to settle these offices: I. using an older building, before its demolition, near the site; II. in a temporary building set up for this purpose; III. in rented rooms in the surrounding buildings. Examples for the use of existing buildings are the building of the Palace of Justice (A. Hauszmann), the extension of the Royal Palace (A. Hauszmann) and the building of the campus of the Royal Joseph University (A. Hauszmann, Gy. Czigler, S. Pecz). St. Stephen's Basilica (M. Ybl), the Parliament (I. Steindl) and the Krisztinaváros wing of the Royal Palace (M. Ybl, A. Hauszmann) are examples where newly constructed buildings were used, and we assume rented apartments as on-site offices in the case of the Opera House (M. Ybl) and the Museum of Applied Arts (Ödön Lechner). The large public building's on-site offices have great significance in architectural history as well as being theoretical and practical workshops.

Abstract The building represents one of the main actors of global warming of the planet because of the significant amounts of energy consumed. In Benin, 44,38% of electrical energy is consumed by office and service buildings. This is explained by the excessive use of air conditioning systems due to the lack of a thermal comfort index specific to the region. This work therefore focuses on assessing the impact of the choice of a thermal comfort model on the energy efficiency of buildings. For this purpose, an office building was chosen in the south of Benin and comfort surveys were conducted among the occupants. The model selected for this purpose is the adaptive model developed by López-Pérez and al. for air-conditioned buildings in humid tropical regions. Subsequently, a monitoring campaign of meteorological, hygrothermal and energetic data of the building was carried out during six months. The results obtained show that the average temperature of the offices (Tf ≈ 24°C) during the hours of occupancy is relatively lower than the comfort temperature determined with the model (Tc = 26.2°C). Moreover, the different simulations carried out under TRNSYS by substituting the office temperatures by the comfort temperature show a reduction of about 20% of the building’s energy consumption. This shows the importance of the comfort model of López-Pérez and al. in improving the energy efficiency of the building.

Building energy management, in terms of both adopted technologies and occupant consumption behaviour, is becoming an essential element of sustainability and climate change mitigation programs. The global COVID-19 pandemic and the consequential lockdowns and remote working had a notable impact on office building operations and provided a unique opportunity for building energy consumption studies. This paper investigates the COVID-19 effects on energy consumption in office buildings, particularly in the education sector. We studied different buildings at the University of Technology Sydney (UTS) campus before and during the pandemic period. The results demonstrate that the changes in energy consumption due to COVID-19 in different UTS faculties are not as strongly correlated with occupant activity. The comparison shows that buildings with administrative offices or classrooms are easier to switch to a remote-working mode than those housing laboratories and special equipment. During weekends, public holidays, or conditions requiring working from home, the per capita energy consumption increases significantly translating into lower energy efficiency. Our findings highlight the essential need for some changes in office building energy management systems. We provide recommendations for office and commercial buildings in general to deal with similar crises and to reduce energy overconsumption in normal situations.

The increasing demand to reduce the high consumption of end-use energy in office buildings framed the objective of this work, which was to design an intelligent system management that could be utilized to minimize office buildings’ energy consumption from the national electricity grid. Heating, Ventilation and Air Conditioning (HVAC) and lighting are the two main consumers of electricity in office buildings. Advanced automation and control systems for buildings and their components have been developed by researchers to achieve low energy consumption in office buildings without considering integrating the load consumed and the Photovoltaic system (PV) input to the controller. This study investigated the use of PV to power the HVAC and lighting equipped with a suitable control strategy to improve energy saving within a building, especially in office buildings where there are reports of high misuse of electricity. The intelligent system was modelled using occupant activities, weather condition changes, load consumed and PV energy changes, as input to the control system of lighting and HVAC. The model was verified and tested using specialized simulation tools (Simulink®) and was subsequently used to investigate the impact of an integrated system on energy consumption, based on three scenarios. In addition, the direct impact on reduced energy cost was also analysed. The first scenario was tested in simulation of four offices building in a civil building in South Africa of a single occupant’s activities, weather conditions, temperature and the simulation resulted in savings of HVAC energy and lighting energy of 13% and 29%, respectively. In the second scenario, the four offices were tested in simulation due to the loads’ management plus temperature and occupancy and it resulted in a saving of 20% of HVAC energy and 29% of lighting electrical energy. The third scenario, which tested integrating PV energy (thus, the approach utilized) with the above-mentioned scenarios, resulted in, respectively, 64% and 73% of HVAC energy and lighting electrical energy saved. This saving was greater than that of the first two scenarios. The results of the system developed demonstrated that the loads’ control and the PV integration combined with the occupancy, weather and temperature control, could lead to a significant saving of energy within office buildings.

Greenhouse gases (GHGs) have caused extreme temperature changes. In January 2023, temperatures were 0.1°C higher than the normal 30-year monthly average. Construction, especially high-rise offices, which occupy 42% of Jakarta, contributes significantly through energy con-Sumption. To reduce carbon emissions, Indonesia has started to implement green retrofits as part of the Net Zero Emission 2050. Due to high costs and lack of public education on new and existing green buildings, the implementation of green retrofits is inhibited, and owners prefer conventional buildings. This research aims to analyze the feasibility and investment risk of implementing green retrofits in high-rise office buildings using the life cycle cost method and the Minister of Public Works and Public Housing Regulation No. 21 of 2021 to generate a feasible and safe in-vestment. It has been proven with cost savings in energy and water consumption of up to 15% compared to conventional office buildings. Profits have also been achieved by providing 9 benefits to the building owner, building manager and building occupants. Therefore, this research has the potential to accelerate the green revolution through feasible and safe green retrofit investments in Jakarta's office buildings.

One of the key elements in meeting decarbonisation targets is improving energy efficiency in the building sector. Although much is being done at the policy level, evidence from practice shows that buildings designed and constructed for energy efficiency often do not meet the efficiency targets. This matter has particular relevance when it comes to non-residential buildings, such as offices. A common problem with existing office buildings is the inefficient management of their HVAC systems, which leads to a waste of energy. The goal of this study is to demonstrate, based on the monitoring of four relatively new offices, the extent to which mechanical ventilation leads to energy performance gaps in office buildings and to estimate the resulting environmental impact over the life cycle of the building. The monitored parameters were the occupancy and indoor environment, focusing mainly on the relationship between the actual occupancy and the CO2 concentration as a parameter representing the performance of the ventilation system. The monitoring results showed that most of the time, the buildings were over-ventilated, with the ventilation rates failing to match the actual demand, resulting in wasted energy. The actual occupancy of the monitored buildings was much lower than their design value. In two buildings, it never reached 50% of the design value. The simulation showed that simply by applying ventilation rate reduction based on a more realistic occupancy schedule, the primary energy demand decreased by 30%. Thus, the building’s annual CO2 emissions could be reduced by up to 12.5%. These findings help to fill in the knowledge gap as to why the building sector is struggling to decarbonise. The results of this work are of great practical value in showing investors, designers and managers the importance of a properly automated and managed building. The practical value of the results was enhanced by the fact that the timeline of the data covered by the analysis began before and ended after the COVID-19 pandemic, making it possible to assess the fine aspects of managing systems in light of the new realities of a changing work culture and office occupancy.

Abstract Biomimicry is an applied science that mainly depends on deriving inspiration from various natural solutions to human problems for making practical applications through the study and examination of natural phenomena, designs, systems, and processes. Historically, designers have dealt with nature as an essential source of innovation and inspiration. In future architecture, biomimicry will be applied to achieve sustainable design. Thus, the paper assumes that biomimicry is an environmental solution for optimizing the thermal performance of office buildings through the building’s skin. The purpose of this paper specifically is to determine and clarify the effective indicators of applying biomimicry to the skins of office buildings in hot climate countries. This will be accomplished by discussing the general concept of biomimicry and its definitions, approaches, and levels. Then, selected examples of biomimetic skin of office buildings in hot climate countries will be shown, analyzed, and compared to determine the most effective biomimetic indicators that will be suggested to be applied to the office building skin. As a result, the effective use of biomimicry as a tool for sustainable design leads to optimizing building thermal performance, optimum thermal comfort for users, and increased productivity for employers in office buildings. Based on indicators, biomimicry as a creative approach to achieving sustainable design will support architects, students, and scholars in achieving sustainable office building design.

Full textAbstract:
Energy-efficient retrofitting has emerged as a primary strategy for reducing the energy consumption of buildings. Buildings in China account for about 40% of total national energy consumption. Large office buildings account for the most. Less than 5% of the building area of existing office buildings is energy efficient. Energy-efficient retrofitting for sustainable buildings is a complicated system that involves various sustainable dimensions and operational technical schemes. Making multi-criteria decisions becomes a challenging problem for stakeholders. Based on the theory of sustainability, this paper establishes a sustainable analysis framework to guide stakeholders to select an optimal technical combination of energy-efficient retrofit measures for large office buildings. Based on empirical data collected in Beijing, a number of energy efficiency measures are selected, tailored and applied to a virtual model of a typical large office building. Technical features and the energy performance are simulated accordingly. The energy consumption, energy-saving ratio and lifecycle costs are derived to identify the optimal configuration. The outcome of this research offers a feasible technical plan for stakeholders relating to technical design and design making. The study finds that an LED lighting system and frequency conversion device for the cooling water chiller cannot only sufficiently reduce the building’s energy consumption but also perform economically. Different thermal insulation materials for reconstructing the building envelope have no obvious effect on the thermal performance in comprehensive simulations of technology combinations. The sustainable analysis framework offers theoretical and practical support and can be used as a reference for the other types of buildings in future research.

Full textAbstract:
Many technical solutions have been developed to enhance the energy efficiency in buildings. However, the actual effectiveness and sustainability of these solutions often do not correspond to expectations because of the missing perspective of design, user’s real needs, and unconsidered negative side effects of their use (rebounds). With the aim to help address these challenges, this paper presents results of a longitudinal living lab study and proposes a user-centered building management system (UC-BMS) as a prototype for office buildings. Based on mixed methods, UC-BMS was co-developed, tested, and evaluated in Germany in up to six office buildings, 85 offices, and within two heating periods. The results demonstrate that such user-oriented approach can save up to 20% of energy while maintaining or even improving comfort and work productivity. The findings show three main areas of intervention and elements of UC-BMS: (1) How interactive design and feedback systems (e.g., air quality) can stimulate ventilation practices and energy efficiency in offices and (2) supporting heating system optimization e.g., by better understanding office behavior. (3) Finally, an office comfort survey was conducted to enable communication between facility management and office users and thus limiting complaints and adapting the heating system towards actual office user needs.

Green building design refers to reducing the energy consumption of buildings through the use of energy-saving and environmentally-friendly technologies during the design and construction of buildings. The consumption of water resources and electric energy in office buildings is significantly higher than that of ordinary residential buildings, which has a greater impact on the environment during the construction process. Therefore, the use of green building design in the design of office buildings plays an important role in reducing building energy consumption. This article takes an office building in Chongqing as an example to explain the green optimization design and provide support for subsequent related constructions.

Full textAbstract:
Against the background of climate protection and the rising costs of a fossil-fuel-based energy supply, the interest in the energy performance and indoor climate of buildings in real operation is rising. This paper, therefore, deals with the indoor climate investigation of two medium-sized office buildings in Germany by taking measurements over a whole year. These relate to one new building and one refurbished building. Sensors of various types were installed and operated in a large number of office rooms, so that in total results are available for over 100 rooms, typically occupied by one or two persons. The analysis focuses on the indoor temperature in summer and the air quality in winter based on the CO2 concentration. The comfort classes according to DIN EN 16798 including the adaptive comfort approach are used as a basis to cluster the results. Both buildings have movable sun protection and openable windows but no facilities for active cooling. They, thus, represent a large number of existing ‘low tech’ office buildings in Germany and central Europe. The results reflect the respective building concepts but also show a wide range between the rooms due to the user preferences and behaviour. The refurbished building shows better results, especially in terms of air quality but also in terms of summer room temperatures. This underlines the benefit of the targeted measures as a result of an analysis of the deficits in the existing building before the refurbishment. The additional measures for decentralised mechanical ventilation and passive cooling are having positive effects. As part of the projects, further measures to improve the indoor climate were investigated in both buildings. In one case, this involved CO2 traffic lights to stimulate personal window ventilation in winter, and in the other, the use of newly developed individual ceiling fans supports convective heat dissipation on the human body during hot spells in summer. The positive effect could be demonstrated for both measures.

Full textAbstract:
To explain the reactions of the building occupants to their acoustical environments, meetings with the designers, walk-through surveys, and detailed acoustical measurements were done. The objective was to determine how design decisions affect office acoustical environments, and how to improve the acoustical design of ‘green’ office buildings. Design-performance criteria were established. Measurements were made of noise level, reverberation time, speech-intelligibility index (SII), and noise isolation. Noise levels were atypically low in unoccupied buildings with no mechanical ventilation, but excessive in areas near external walls next to noisy external noise sources—especially with windows open for ventilation—and in occupied buildings. Reverberation times were excessive in areas with large volumes and insufficient sound absorption. Speech intelligibility was generally adequate, but speech privacy was inadequate in shared and open-office areas, and into private offices with the doors open for ventilation. Improvement of the acoustical design of ‘green’ buildings must include increasing the external-internal noise isolation and that between workplaces, and the use of adequate sound absorption to control reverberation and noise.

The construction industry engages in renovation work to improve the physical, economic, and environmental aspects of office buildings. During consideration of renovation of deteriorated office buildings, it is critical for project owners to estimate the change in monetary value of the office buildings due to the completed renovation work. Nevertheless, related research and methods for predicting this value remain insufficient. In this study, the monetary value prediction model for post-renovation office buildings was developed by using artificial intelligence techniques and multivariate data analysis techniques based on 90 actual cases of renovated office buildings. The model application results showed (i) relatively high prediction performance (average error rate of 14.12%) and (ii) advantages in various aspects compared to existing approaches. It is expected that project owners considering office building renovations can be supported in decision-making by the developed proposed model. Furthermore, this research will contribute to promoting the office building renovation market.

The article defines the main criteria of office buildings intelligence, describes the stages of intelligent buildings formation, analyzes the profitability of the introduction of modern technical means (engineering systems) and architectural planning techniques in office buildings. At different stages of civilization, the concept of "technology" defines the path leading to future progress, and the rate of technology change is directly proportional to the rate of progress. Nowadays, artificial intelligence is extremely important for the functioning of modern office buildings, including the impact on the environment, resource conservation, safety, comfort and life support. According to research based on the works of scientists such as Derek Clements-Croome, Mervi Himannen, Akin Adejimi and others, and based on the analysis of intellectual buildings of the world from the 50s of the twentieth century to the present, 4 stages of intelligent buildings formation were identified. At the first stage (1950-1980) of the formation, separate controllers were introduced. At the second stage (1980-1995), the introduction of the "artificial intelligence" - Building Management System (BMS) - was developed and used. At the third stage (from 1995 to 2010) an intelligent building management system (IBMS) was introduced, which can independently identify threats, look for ways to achieve results and make decisions. Starting from 2010, we can highlight the fourth stage of development of the intelligent buildings, in which, in addition to the availability of the intelligent management system (IBMS), it became necessary to use approaches of sustainable architecture. The research results indicate that the office building should be classified as an "intelligent building" if it meets the following criteria: 1. Has artificial intelligence (IBMS), which autonomously manages the building; 2. Has at least 15 thousand information points, in other words, sensors and controllers, through which information is received from controlled engineering systems about the state of equipment and the environment, the state of building structures, etc.; 3. Complies with the principles of sustainable architecture, when planning and architectural techniques can minimize the negative impact of buildings on the environment through energy efficiency. The article proves that the office buildings intelligence is determined by the availability of both technological means and the optimal architectural concept, which minimize the negative impact of buildings on the environment; improve energy efficiency and conditions of the building exploitation. Therefore, further research of intelligent buildings from the point of architectural view is necessary, because a modern office building must be designed with the ability to adapt to rapid changes in technology and human needs.

The Kingdom of Saudi Arabia is working to establish cities based on the economy and attract investments such as Neom and The Line. Moreover, at the beginning of 2021, the Saudi government announced that it will stop dealing with foreign companies that establish regional offices outside the country, starting from the beginning of the year 2024. These acts will contribute to strengthening the presence of office buildings significantly. However, the biggest challenge is the inefficient energy design and operation of the existing office buildings in an overheated environment. Therefore, improving the thermal performance of existing office buildings has become a priority for sustainable development. This study aims to evaluate the current scenario of energy performance in Saudi governmental office buildings. One of the most important strategies of the Kingdom’s vision 2030 regards energy conservation. In support of the aim of this research, the annual electric energy bill of the Agricultural Development Fund building in Najran has been collected and analyzed. Accordingly, the analyses were carried out to evaluate the improvement in energy consumption through retrofitting the building envelope. DesignBuilder simulation program was used to investigate the effects of different retrofitting strategies of the building envelope in terms of changing the type of window’s glass, adding thermal insulation layers, and applying egg-crate shading devices. The results reported that applying a combination of those strategies reduced total energy consumption by 26.81% compared with the current base case.

Office buildings constitute a significant proportion of the non-residential building stock. In recent years, various rating tools have been developed to foster green office building development. The Green Building Council of Australia (GBCA) has developed the Green Star - Office rating tools for this purpose. There are an increasing number of stakeholders adopting these tools to showcase their efforts in sustainable development. This research focuses on the challenges and barriers in obtaining GBCA ratings in Australian Office buildings. To accomplish this, the scoring sheets from the rating of 264 certified office buildings were collected and critically analysed. The findings indicated that credits related to the attributes of innovation, ecology and energy are comparatively difficult to achieve. It was also found in this study that a large number of projects did not apply for the specific credits of refrigerant global warming potential, re-use of façade, topsoil and fill removal from site, and individual comfort control. This study provides a useful reference to both the property developer and the Green Building Council of Australia for green building developments in the future. In particular, the findings provide useful inputs to the development of the next generation of green building rating tools.

Tall buildings are being designed and built across a wide range of cities. A poorly designed tall building can tremendously increase the building's appetite for energy. Therefore, this paper aims to determine the design strategies that help a high-rise office building to be more energy efficient. For this purpose, a comparative study on twelve case buildings in three climate groups (temperate, sub-tropical & tropical) was performed. The exterior envelope, building form and orientation, service core placement, plan layout, and special design elements like atria and sky gardens were the subject of investigation. effectiveness of different design strategies for reducing the cooling, heating, ventilation and electric lighting energy usage. Finally, lessons from these buildings' were defined for the three climates. Furthermore, a comparison of building energy performance data with international benchmarks confirmed that in temperate and sub-tropical climates sustainable design strategies for high-rise buildings were performing well, as a result leading to lower energy consumption. However, for the tropics the design of high-rise buildings needs additional consideration.

A barrier to green-building development is the uncertainty and scepticism about the financial implications. This study aimed to investigate whether the green-certification schemes help buyers to recognize the benefits of green office buildings by their willingness to pay a premium for such buildings. The study used a hedonic-model based on a sample of 67 prime office buildings (including non-green comparables) certified by HKBEAM, BEAM-Plus and LEED in Hong Kong. The empirical findings suggest that green certification schemes add extra value to an office property. The rental value of office properties certified by HKBEAM, BEAM Plus and LEED is about 10.9% higher than for non-certified office buildings. More specifically, tenants/users are willing to pay a premium of 10.9% for green-certified office properties. The findings have practical implications in encouraging green building development in Hong Kong and elsewhere. The findings indicate that the higher rental income from green office buildings can cover the additional cost of obtaining green certification within a period of 22-months (22.32 months) in Hong Kong. The results provide references for various stakeholders (developers/investors/users) in establishing the business case for green-office buildings, because of the ability of the market to capitalize the environmental benefits of green office properties.

Findings – The findings confirmed property investors incorporate several adaptive and flexible space design and specifications in their modern office buildings to enhance space flexibility and functional efficiency. These include adaptive building structures, efficient floor plates, flexible building services, advanced IT networking, high-quality building amenities and modern building materials. Building structures and layouts are designed to be modified quickly and cost effectively to address tenants’ changing needs. Implications affecting tenant demand for flexible spaces on their lease contracts were also identified. Research limitations/implications – The findings from this research have implications for management of office space. Although the data were sourced with reference to buildings located in New Zealand only, the findings are applicable to office buildings in other countries. Practical implications – The study provides an insight into design strategies adopted in modern office buildings to enhance space flexibility and functional efficiency. These findings are of practical application to professionals involved in the design, development, investment and valuation of modern office buildings. Originality/value – The paper provides in-depth insights into how investors meet tenants’ changing demand for physical space which is linked to delivering improved and stable market-driven returns to investors.

Purpose – The purpose of this paper is to address two major challenges faced by sustainable building owners: first, address the gap between an occupant’s expectations of sustainable building outcomes and what the building actually provides and second, overcome the lack of user knowledge about sustainability design and operation for a particular with regards to performance. Design/methodology/approach – This study used a focus group approach to investigate the gap between: user expectations and sustainable building performance. The study surveyed occupants of sustainable office buildings in Melbourne, Australia. Findings – There is no significant relationship between users’ expectations and users’ experience of sustainable building performance and users’ knowledge about sustainability and the building they were worked in. Research limitations/implications – The research was limited to sustainable office buildings. New office buildings seeking to incorporate sustainability which need to focus on the needs of tenants in order to maximise value. Practical implications – There is an urgent need to ensure sustainable office buildings meet the needs of present and future occupiers without compromising short and long-term occupier satisfaction levels with regards to sustainability and operation of the building. Social implications – Increasing the level of sustainability in office buildings has been a major trend over the past decade however the tenants need to be consulted in the post-occupancy phase. Originality/value – Little attention has been given in the property management literature to sustainable office buildings and value drivers. This is an original and innovative study, partly due to the recent developments in sustainable buildings.

Full textAbstract:
The article is dedicated to one of the most essential areas in the construction industry: consideration of the issues related to resource saving, ecologically and economically rational use of natural resources in accordance with “green standards” of the commercial property buildings, offices, in particular. During the operation of office buildings there takes place negative impact on all the components of the environment. Herewith, the first issues considered by the operating organizations are the cost of the facility, safety of technological processes, reliability, durability and operational characteristics, and only then the issues of building environmental friendliness and energy efficiency, the consequences of which are irrational use of natural resources and accumulation of environmental damage. The number of existing systems certifying “green” buildings is insufficient to create a stable human environment. Formation of the resource saving mechanism during the operation of office buildings requires the application of the “green” standards criteria, making it possible to provide results of the stable approaches during the entire operational lifetime of the building. Based on the local and foreign experience in resource saving stimulation under the “green standards” the article provides the estimation criteria making it possible to implement the ecological and economic evaluation of the resource saving mechanism during the operation of office buildings.

Purpose Green building construction was adopted as a strategy to reduce energy consumption and the overall impact of the built environment on our natural environment. However, in Malaysia, previous studies have reaffirmed that green office buildings consume a substantial amount of energy, compared to their counterparts in Singapore. Moreover, there is still a significant performance gap between predicted energy measurements and actual operational energy consumption of green office buildings in Malaysia, due to occupants’ behavioural discrepancies. Therefore, the purpose of this paper is to develop energy efficiency practices for occupants of green office buildings in Malaysia. The developed practices integrate technology, organisation policy, and occupants’ behavioural strategies, in order to reduce the energy consumption of green office buildings in Malaysia. Design/methodology/approach To achieve the research goal, a mixed (quantitative and qualitative) research method was used to collect data from the research population. In total, 53 respondents working in a green office building complex in Kuala Lumpur Malaysia were surveyed using a questionnaire. Additionally, three top management staff of the green office building and two Malaysian construction professionals were interviewed. The study adopted convenience sampling technique in selecting the research respondents. The data from the questionnaire were analysed using SPSS software (version 22) while the interview data were analysed via thematic content analysis. Findings The findings suggest that the integration of technological strategy (use of BIM tools, sustainable building materials, etc.); organisational strategy (develop, implement and evaluate action plans, use of monitor/control systems, etc.); and occupants behavioural strategy (training, incentives, occupants energy efficiency guide, etc.) will critically reduce energy consumption of green office buildings in Malaysia. Originality/value Based on the findings, energy efficiency practices are developed to guide occupants in reducing the energy consumption of green office buildings in Malaysia. This strategy will contribute to reducing the performance gap that exists between predicted energy and actual energy use of green office buildings in Malaysia. However, the developed energy efficiency practices need to be validated to ascertain its workability in the green office building context.

One of the facilities and assets owned by Bank Indonesia is an official residence intended for permanent employees, office buildings, and other facilities such as borrowing rooms and goods that can be used by employees to support office activities. But in the implementation of maintenance of official houses and office buildings as well as the process of requesting room loan and goods still done manually. Therefore, a Building Management application is needed that can help the maintenance activities of official house buildings and office buildings as well as the process of requesting the loan of rooms and goods. Building Management application is a software that is used for building maintenance and management of all building needs including borrowing space and goods in an office building. This study aims to accelerate the process of requesting repairs to official office buildings and office buildings as well as borrowing rooms and goods. In addition, this application also generates automatic report recording output. The method in this study use V-Model is an extension of the waterfall model and is based on the association of the testing phase to each appropriate development phase. The result in this study is application to be built is based on the website using the CodeIgniter framework and the V Models system development method with stages arranged starting from verification which contains the needs analysis stage, design to the coding phase and also the validation process that contains testing of the application to determine application functionality and also know the level application usability for the user.

Full textAbstract:
Energy use intensity (EUI) is a significant index for energy management in the building sector; however, previous research that determined an EUI benchmark for a type of building resulted in serious problems. Such earlier EUI benchmarks cannot fairly evaluate office buildings with different proportions of parking areas and different numbers of floors, becoming an obstacle for energy management. Therefore, this study proposes an area-weighted office building EUI benchmark that calculates according to office areas and parking areas. This study subsequently surveys the electricity consumption of 58 office buildings in Taiwan to determine the office area EUI benchmark that depends on the number of floors in a building, and suggests a reasonable parking area EUI benchmark. Finally, this study promotes a fairer EUI benchmark and ranking system for office buildings in Taiwan. Such a benchmark and ranking system act as a reference for the promotion of the building energy certificate system in Taiwan.

Full textAbstract:
In recent years, many green buildings were built across China, but the actual performance is not as good as expected. Therefore, it is necessary to improve their performance and establish an objective energy consumption baseline as well as the benchmarking approach for green office buildings in Shanghai. Firstly, we categorized the green office buildings in Shanghai into two type - small and large, according to their floor area. Then we defined the baseline of EUI (energy use intensity, kWh/sq.m.a) based on the survey and submetering data and developed the reference models for both small and large green office building. Secondly, we specified four EUI reference levels for each type after studying the energy saving potential of green office buildings in Shanghai. Thirdly, in order to make the benchmarking approach more objective, we proposed EUI correction method for office buildings considering three main influencing factors - schedule, occupant density and meteorological parameters. We established a typical building model library of office buildings in Shanghai. We adopted regression analysis to obtain the corrections for schedule and occupant density. As for meteorological parameters, by classifying the typical days and calculating their representative EUIs, we determined the correction method.
