City image includes people's perceptions of the built and natural environments as well as the emotions and ideas the city arouses in them. In the city image, the preservation of the buildings, especially historical buildings, which carry the past cultures, meaning and structural features of the city to the present day, can be ensured by making these buildings visible and perceptible by the inhabitants. Historical buildings' visibility can facilitate the recognition and appreciation of their historical significance, thereby contributing to the preservation of the city's cultural heritage. This study aims to analyse the visibility of a historical building that holds a significant place in the urban memory and to suggest recommendations for enhancing its visibility. In this context, the viewpoints used to examine the İskenderun Beş Temmuz Primary School Historical Building’s visibility were specified by space syntax visibility graph analysis (VGA). Subsequently, the building's visibility in three different historical periods was determined by the isovists technique, utilizing these viewpoints. Based on the same viewpoints, an observational field study and a survey applied to 47 people were conducted. Consequently, it was identified that the historical building could not be sufficiently seen due to the presence of surrounding service structures, perimeter walls, and high buildings. Furthermore, this study proposed the removal of additional structures that negatively affect historical building's visibility. Additionally, a design approach was developed for new buildings and landscaping to enhance the historical building's visibility, and the efficacy of the proposed design was evaluated through isovists and VGA analyses.

Several studies have analyzed the integration of energy-saving strategies in buildings to mitigate their environmental impact. These studies focused mainly on a disaggregated analysis of such strategies and their effects on the building's energy consumption and thermal behavior, using energy engine simulation software (EnergyPlus, TRNSYS, and DOE2) or graphical interface software (DesignBuilder, eQuest, and ESP-r). However, buildings are complex systems whose energy behavior depends on the interaction of passive (e.g., location and construction materials) and dynamic (e.g., occupation) components. Therefore, this study proposes a composite indicator Building’s Energy Performance (BEP) as an alternative to deal with this complex and multidimensional phenomenon in a simplified way. This indicator considers energy efficiency and thermal comfort. The Electrical Engineering Building (EEB) of the Universidad Industrial de Santander was selected to verify the performance of the BEP indicator. In addition, a sensitivity analysis was performed for different mathematical aggregation methods and weighting values to test their suitability to reproduce the building behavior. Different simulation scenarios modeled with DesignBuilder software were proposed, in which the energy-saving strategies integrated with the building was individually analyzed. The results confirmed that the integration of the building's energy-saving strategies improved the BEP indicator by approximately 16%. It has also been possible to verify that the BEP indicator adequately reproduces the building’s energy behavior while guaranteeing comfort conditions. Finally, the Building Energy Performance indicator is expected to contribute to the integration of sustainability criteria in the design and remodeling stages of buildings.

DKI Jakarta, as the capital of the Republic of Indonesia, has the highest population density in Indonesia, with a population of 16,334 people / km2. Therefore, community facilities and infrastructure within the DKI Jakarta Provincial Government play an important role so that community service can be carried out properly. As one of the main infrastructures, State Buildings must have building reliability as stated in the technical requirements stipulated in Presidential Regulation Number 73 of 2016. Building maintenance is an activity to maintain the building's reliability and infrastructure, and facilities so that the building always functions properly. Based on a survey conducted by the DKI Jakarta Provincial Office for The Creation of Works, Spatial Planning and Land Use in 2019, the number of building assets of Province DKI Jakarta are 9823 buildings. 60% of those buildings were classified as Simple-Building category. Due to the numerous building assets, maintenance activities need to be supported by an adequate maintenance system. This study aims to develop a building maintenance system based on web. The methodology used in this research are expert validation, interviews, field survey and literature studies. The results of the validation process will be developed into a simple-building’s web-based maintenance system framework.

t has been argued that green buildings have a better indoor environmental quality than conventional buildings and that this translates into a more satisfying workplace for the building's occupants and, inturn, a more productive workforce. Assessing a building's cost effectiveness means taking into account all the costs that will be incurred during its life cycle not just development costs. People found no evidence to believe that green buildings are more comfortable than conventional building. In fact, the only difference between the buildings was that occupants of the green building were more likely to perceive their work environment as warm, and occupants who felt warm were more likely to describe their work environment as poor.

Testo completoAbstract (sommario):
Flex−buildings are buildings which are literally designed to change. A flex−building must be able to accept different infills and its users must be able to easily adapt their surroundings. Flexibility is defined as the capacity of a building to undergo modifications and accept changes of function with limited structural interventions. More than 40% of the activities housed in a flex building can continue to function during modification. Studies into flex−buildings (commissioned by the Dutch Government) have elicited a number of insights. These are not hard−and−fast conclusions but more in the region of statements and reminders for those involved with flex−buildings. These studies show that it takes more than civil engineering to successfully realise such buildings. Aspects of use and management are at least as important. Besides, it requires designers who are willing to let go of their design after it is finished. For the result is not a completed ‘architectural’ product but a continually changing object. Following insights (among others) will be illustrated with built and unbuilt projects in the Netherlands. • The façade design, for example, figures prominently in designing flexible buildings. It makes special demands on the design’s presentation during the design process, as the building can assume different appearances over time. The double facade is a promising concept that allows for expressive and/or open facades in flexible buildings. It can also help to reduce a building’s energy consumption. • Also by deliberately incorporating excessive space and construction a building has the necessary leeway to accommodate future developments. A building’s flexibility is enhanced by oversize in structure as well as space. • A big multi−use building in Rotterdam (H. A. Maaskant / W. van Tijen (1951)) and recent projects of RUIMTELAB are presented as case−studies. These are an inspiration for architects and planners looking for design tools to help achieve an open architecture.

Many studies and reports have discussed various aspects of the "business case" for green buildings in recent years, but this report is an attempt to compile all reliable data from around the globe into a single, comprehensive resource that includes international examples and thought pieces from top experts. The final section of this study explores the effects that a greener built environment can have on a macro scale as well as how this can be accomplished. This report examines the business costs and advantages of green building in essential categories. According to the research, there are a variety of compelling advantages to building sustainably that are enjoyed by various stakeholders over the course of a building's life. However, whether it is possible to put a monetary value on the advantages of green buildings has remained debatable. This is information that real estate lenders and the investment community need. Do green buildings command a higher price when it comes to buying and renting? Are tenants and occupants finding them more appealing?

Testo completoAbstract (sommario):
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.

AbstractUsing seesaw structural system equipped with energy dissipating devices has been considered as a low-cost and low-tech way for creation of earthquake-resilient buildings. In this paper by considering three groups of multi-story buildings, including conventional buildings, LRB-based isolated buildings and building with seesaw structure, equipped with a newly introduced type of structural fuses, their seismic performances have been compared through nonlinear time history analyses (NLTHA). The employed fuses in seesaw buildings are a specific type of yielding plate dampers, called Multiple Curved Yielding Plate Energy Dissipater (MCYPED), installed at the bottom of the all circumferential columns of the lowest story of the building. To show the efficiency of the proposed seesaw system in comparison with other two mentioned groups, first, by finite element modeling, verified by experimental results, the initial and secondary stiffness values as well as the yielding and ultimate strengths of the MCYPEDs have been obtained to be modeled by multi-linear plastic springs in the seesaw buildings. Then, a series of NLTHA have been performed on the three groups of buildings by using a set of selected earthquakes. The compared responses include roof displacement and acceleration, base shear, inter-story drift and finally plastic hinges (PHs) formed in the building’s structures. Results show that the proposed seesaw building equipped with MCYPEDs not only results in lower seismic demand, similar to base isolation system, but also leads to remarkable energy dissipation capacity in the building structure at base level, so that the building structure remains basically elastic, and does not need any major repair work, even after large earthquakes, contrary to the conventional building which need to be demolished after the earthquake.

Industrial building energy consumption accounts for more than half of building energy consumption. In order to understand the situation of energy consumption of industrial building’s energy system in Shenyang located in China's northeast severe cold region, we investigated the distribution of industrial buildings and energy system’s energy consumption (HVAC, water supply and drainage, electrical system) of typical industrial buildings in Shenyang, it is found that the energy system’s energy consumption of Shenyang is great because of long-term neglecting of industrial building’s energy conservation. We must strengthen the designing of energy conservation, applying of new technology and supervising of industrial building to develop the potential of industrial building’s energy conservation.

This study has analysed which options would be appropriate to use as additional requirements to the main requirement of primary energy number in the new Swedish building regulations. The starting point is to ensure that buildings are built with good qualitative properties in terms of the building envelope so that low energy use can be maintained throughout the life of the building despite changes in installation systems or the building’s occupancy. The additional requirements should aim to minimize energy losses, i.e., to ensure that the building's total energy demand is low. The following possible additional requirements have been examined: net energy demand, net energy demand for heating, heat power demand, heat loss rate and average heat transfer coefficient. In order to ensure that the additional requirements will work as desired and to explore possibilities with, and identify the consequences of, the various proposals, calculations have been made for four different categories of buildings: single-family houses, apartment buildings, schools and offices. The results show that the suggested option net energy demand will not contribute to any additional benefits in relation to primary energy number. The other options analysed have both advantages and disadvantages and it is difficult to find a single additional requirement that fulfils all the pre-set demands.

Testo completoAbstract (sommario):
Buildings are widely regarded as potential sources for demand flexibility. The flexibility of thermal and electric load in buildings is a result of their interactive nature and its impact on the building’s performance. In this paper, the interaction of a building with the three interaction counterparts of the physical environment, civil infrastructure networks and other buildings is investigated. The literature review presents a wide variety of pathways of interaction and their associated potential impacts on building performance metrics such as net energy use, emissions, occupant comfort and operational cost. It is demonstrated that all of these counterparts of interaction should be considered to harness the flexibility potential of the buildings while maintaining other buildings performance metrics at a desired level. Juxtaposed with the upside potential for providing demand flexibility, numerous implementation challenges are identified that are associated with the evaluation and financial valuation of the capacity for demand flexibility, the aggregated flexibility potential, as well as the control and communication to facilitate the interactions.

As the population grows, the need for safe and comfortable places to live and work increases. Tall buildings are becoming a popular option as they enable efficient use of urban space and provide solutions to the challenges of urbanization. However, the safety of these buildings against natural hazards such as earthquakes is crucial. Engineers are putting a lot of effort into the construction and design of tall buildings, some of which have been successfully completed, while others have been halted due to design difficulties. High-rise buildings have challenged engineers' endurance due to their height and number of floors. Efforts have been made to increase the resistance of tall buildings to natural factors and the weight of the building. One of the most important factors is the building's vibration movement, which must be resistant to wind, loads on the building, and earthquakes. One way to increase the strength of the building is to use isolated foundations. This article investigates whether using an isolated foundation has an effect on the strength of tall buildings. Two 51-floor tall buildings were designed, one with an isolated foundation and one without. The differences between the buildings were evaluated in terms of earthquakes, the greatest risk for buildings. Using the ETABS program and following international standards, these two buildings were designed to withstand the forces of wind, earthquakes, and loads on the building. The loads and forces caused by earthquakes, the resistances and possible damages of both types of buildings were also evaluated

To promote sustainability in construction, planning must include dynamic analysis of renewable energies, as traditional methods fall short for this transition. Building simulation, essential for future planning, is often hindered by the time and cost required for detailed modeling. The proposed solution, generic modeling, automates the creation of 3D building models using basic early data or regulations, reducing time and expense. This paper focuses on applying this method to office buildings, exploring its algorithm, methodology, and practical uses, while acknowledging its limitations in model variability. This automated approach facilitates early energy sustainability evaluation and has the potential to scale up to district-level modeling.

<p><span lang="EN-US">The number of high-rise buildings in the big cities of Indonesia is increasing along with land being more limited and its prices being very high. Most of these high-rise buildings are in Jakarta and some of them are facing the risk of building failure that may cause business and operation interruption. These buildings that have been erected and operating need to receive regular maintenance and supervision to ensure the building's condition and safety. Many building owners and managers do not conduct and plan maintenance and supervision properly causing these buildings of being at risk of fire and building structure – mechanical failure / damage. For this reason, rigorous regulations, and its enforcement in building construction and maintenance are needed to ensure that these buildings operate reliably and encourage building owners and facility manager to comply with them properly. Cultivated Penalty and strict sanctions need to be renewed and must be implemented properly by Government bodies and local authority. Building Audit Institute can be formed to assist the central government and local governments (Governor) in carrying out their functions to ensure the safety and security of buildings, including their users. Strengthening existing laws and regulations will greatly assist in law enforcement and certainty for owners, building managers and building users, which in turn will support national development.</span></p>

Testo completoAbstract (sommario):
The impact of wind on tall buildings is not uniform and varies according to the building’s shape and size. Designing a tall building with a regular plan shape is relatively straightforward due to the abundance of available data. Codal provisions for tall buildings are mostly accessible when the building’s plan geometry remains unchanged. Data availability is limited to regular shapes, where modifications are not incorporated in tall buildings. Therefore, it is essential to investigate wind effects on buildings with non-regular shapes. Two widely used methods for such investigations are wind tunnel testing and Computational Fluid Dynamics (CFD). While wind tunnel testing is time-consuming, CFD methods can be adopted for preliminary wind tests. It is crucial to validate CFD results before interpreting them for any analysis. Wind predominantly exerts positive forces on the windward corner, while negative forces are observed on the leeward and side faces of high-rise building models.

Glass is the major component of the building envelope to provide visual comfort to inside the buildings. In général clear and bronze glass was used as a main building envelope for both residential and commercial buildings to provide better day lighting into the buildings. If we use more glass area as a building envelope more radiation allows into the buildings. So that it is necessary to reduce more solar radiation and provide sufficient daylight factor inside the building's through glass windows with the help of external devices called shading devices. In this work four shading devices was tried on bronze glass window to find the heat gain and daylighting into buildings. This paper presents the experimental measurement of spectral characteristics of bronze glass which include transmission and reflection in entire solar spectrum region (300nm-2500nm) based on ASTM standards. A MATLAB code was developed to compute visible and solar optical properties as per the British standards. A building model was designed by design builder software tool. 40% window to wall ratio was considered for building models, thermal and day lighting analysis of buildings through windows was carried out in Energy plus software tool for hot and dry climatic zone of India.

Testo completoAbstract (sommario):
Many buildings around the world fail to meet current earthquake resistance requirements and have significant potential to be a risk to human life and property. Therefore, a seismic upgrade of such buildings is quite necessary. Over the past decades, hundreds of buildings have been strengthened and upgraded to improve their seismic resistance, and thousands more are planned for years to come. In Israel, this was followed by National Outline Plan No. 38, which provides a basis for retrofitting and adding new areas to existing buildings. It should be noted that adding new floors to existing buildings increases seismic forces. Moreover, structure material properties change over a building’s lifetime, which should be also considered for strengthening. The proposed research investigates and validates the existing practice for strengthening and upgrading buildings in seismic regions and suggests ways of improving their efficiency. Experiments and numerical analysis were performed on a real existing residential building that requires strengthening and upgrading. A corresponding methodology was proposed for monitoring the strengthening and upgrading processes, including selecting measurement devices and their real use. Using sensors with the highest sensitivity enabled measurements of micro-vibrations and investigations of the recorded signal to obtain the building’s natural vibration frequencies. Experimental measurements allowed us to distinguish different frequencies of the building at all strengthening and upgrading stages. The measured dynamic parameters of the building allowed a more accurate calculation of seismic forces for all of these stages and consequently made the design more effective. Therefore, we recommended monitoring buildings in each stage of seismic strengthening and upgrading.

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.

The paper discusses thermal quality improvement in historic buildings. It is based on a case study of a wooden historical building in an architectural style typical of Zakopane, located in the Podhale region of Poland. The building’s historical value and timber structure prevent the application of typical thermal retrofitting solutions. This paper presents an analysis of the possibilities of the improvement of energy performance of a historic building (villa) which included: a review of the available energy performance improvement solutions applicable to this type of building, with a particular focus on applying internal insulation; a technical condition assessment using non-invasive methods, the identification of problematic areas in terms of the thermal retrofitting of buildings with timber walls and decks; in situ tests: thermovision tests which showed the places with temperature distribution field disturbances in the building’s envelope, focusing on thermal bridges; measurements of actual thermal transmittance coefficients for extant partitions; measurements of the building’s airtightness and the microclimate in selected rooms; numerical analysis: an assessment of the influence of the thermal bridges on the building’s existing condition, an analysis of water content changes in wall systems post-insulation. The presented approach enables the improvement of the energy performance of timber historical buildings while preserving the historical value of its architecture. It is innovative because it tries to fill in a research gap concerning a lack of relevant guidelines in Poland. The research questions that the authors asked were as follows. Is it possible to improve the thermal insulation of a building’s wooden walls without adversely affecting the building’s technical condition? With regard to the necessity to meet nZEB (nearly zero energy building) standards, is it feasible to improve the timber walls of historical buildings? The study found that under the correct assumptions and while maintaining a responsible approach to design, it is possible to improve the energy performance of historical buildings without interfering with historical heritage.

The buildings were classified into nine distinct types and initially extracted from a satellite image of the year 2015. Secondly, changes were identified based on a visual interpretation of an image of the year 2017, so that new buildings, demolished buildings and building upgrades can be quantitatively analyzed. The data was aggregated by administrative wards and a hexagonal grid with a diameter of 250 m to protect personal rights and to avoid the misuse of a single building’s information. The dataset shows an increase of 19,391 buildings between October 2015 and August 2017, with a variety of interesting spatial patterns. The center of the city is mostly dominated by building changes and upgrades, while most of the new buildings were constructed within a distance of five to six kilometers from the city center.

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.

Buildings are significant consumers of energy and producer of greenhouse gases worldwide, and serious efforts have been put into designing energy-efficient buildings. Significant technological advances have been achieved in developed countries; however, advances have rarely been adopted in developing countries like Afghanistan. Such trends emerge from the lack of research in designing energy-efficient buildings to local conditions, practices and materials. This research focused on building energy modelling and simulation to evaluate the energy performance impact of different shading and orientation. The research design follows a case study over an actual seven-storey multi-apartment residential building in the city of Mazar-I-Sharif, Afghanistan, using primary field data and dynamic simulation. Findings demonstrated that neighbouring structures have a positive correlation with a cooling demand. Meanwhile, south is the optimal orientation to face the building's glazed façade, saving up to 7.4% of cooling and 9.7% of heating energy. Moreover, movable shading devices installed on the building's openings in the summer season reduce the building energy load up to 19%, with a total energy cost reduction of AFN. 188,448 ($2447.37 US) annually. The study underlines the vast research scope in customizing building designs to Afghanistan's climatic conditions and other developing countries, thus contributing to buildings’ sustainability.

Testo completoAbstract (sommario):
Occupancy, which refers to the occupant count in this paper, is one of the main factors affecting the energy consumption of commercial buildings. It is important for both building managers and energy simulation engineers to understand how an entire building’s energy consumption varies with different occupancy levels in the process of building automation systems or in assessments of building performance with benchmarking lines. Because commercial buildings usually have large scales, complex layouts and a large number of people, it is a challenge to simulate the relationships between an entire building’s energy consumption and occupancy. This study proposes a fast method for calculating the influence of occupancy on the energy consumption of commercial buildings with different building layouts and existing occupancies. Other occupant behaviors, such as the opening of windows and adjustment of shading devices, are comprehensively reflected in two basic building parameters: the balance point temperature and the total heat transmission coefficient of the building. This new method can be easily used to analyze how building energy varies with occupancy without a physical building’s energy model. An office building in Shanghai is taken as a case study to validate the proposed method. The results show that the coefficient of determination R2 between the calculated value and actual value is 0.86, 0.8 and 0.71 for lighting, cooling and heating energy, respectively, which is suitable in engineering applications.

Testo completoAbstract (sommario):
The existing performance gap between the design and the real energy consumption of a building could have three main origins: the occupants’ behaviour, the performance of the energy systems and the performance of the building envelope. Through the estimation of the in-use Heat Loss Coefficient (HLC), it is possible to characterise the building’s envelope energy performance under occupied conditions. In this research, the estimation of the HLC of two individual residential buildings located in Gainsborough and Loughborough (UK) was carried out using an average method. This average method was developed and successfully tested in previous research for an occupied four-story office building with very different characteristics to individual residential buildings. Furthermore, one of the analysed residential buildings is a new, well-insulated building, while the other represents the old, poorly insulated semidetached residential building typology. Thus, the monitored data provided were filtered in order to apply the abovementioned average method. Even without fulfilling all the average method requirements for these two residential buildings, the method provides reliable HLC values for both residential buildings. For the house in Gainsborough, the best estimated HLC value was 60.2 W/K, while the best approach for Loughborough was 366.6 W/K. Thus, despite the uncertainty sources found during the analysis, the method seems promising for its application to residential buildings.

This paper presents the common construction and structural deficiencies noticed in Mahakali municipality Darchula. The RC building constructions are common in the Darchula district. The main objective of this study is to find existing structural and construction mistakes in RC buildings. Field observations, interviews with engineers, technical people, local house owners, photographs, reviews of works of literature, bye-laws, buildings code, etc. are taken to fulfill the objective ofthe study. This paper examines the cause and effects of faulty construction practices and structural defects by using both analytical and numerical methods. Structural defects are present in the RC buildings due to improper construction methods, poor use of bye[1]laws, poor workmanship; do not consult with professionals, corruption, lack of training, etc. The results show that these structural defects and faulty constructions practice may lead to serious failures of structures during strong earthquakes. This study provides relevant information on the building’s collapse in a recent earthquake (Gorkha 2015) and the major cause of failure of RC buildings to compare the defects present in existing RC buildings in the Darchula district. The results concluded that almost 48% of buildings have column sizes less than 300mmx300mm, 24% of buildings have poor beam-column joints and 11% of buildings are soft storey and irregular building shapes. The numerical results pointed out that non-engineered buildings show poor seismic performance, poor seismic capacity and failure mechanism. The study strongly recommended that to prevent future hazards, the construction of buildings should follow the building’s laws and codes and also should be ensured by the municipality and other government bodies also provides sufficient training and knowledge in the local level. To improve the existing structures, it is important to increase the strength capacity and ductility of the joint by providing a suitable retrofitting process or maintenance process.

Testo completoAbstract (sommario):
Since decoration is an essential part of buildings, the carbon emissions generated by decoration work should not be ignored. In recent years, prefabricated decoration has attracted much attention as efforts are made to pursue green, low-carbon, and waste-reducing buildings. However, research on carbon emissions assessment of prefabricated buildings has focused mainly on the structural aspect of prefabricated buildings, with few studies having considered prefabricated decoration. This study therefore focuses on assessing the carbon emissions of prefabricated decoration from the life cycle perspective of a case study residential building and explores the potential for reducing carbon emissions by decorating buildings with prefabricated components. The results show that using prefabricated decoration in the case study building reduced carbon emissions by 29.08% at the building material production stage compared to traditional decoration, and using an optimized design of prefabricated decoration, the building’s energy consumption over its design life could reduce carbon emissions by 1046 kgCO2/m2. These findings demonstrate the benefits of prefabrication decoration for reducing carbon emissions. This study provides decoration companies with robust data and insights to guide future decisions and practices, helping to transform and achieve the carbon neutrality goal for the building decoration industry.

Buildings consume large amounts of energy, and their transformation from energy users to producers has attracted increasing interest in the quest to help optimize the energy share, increasing energy efficiency and environmental protection. The use of energy-efficient materials is among the proposed approaches to increase the building’s energy balance, thus increasing the performance of building facades. Semitransparent building-integrated photovoltaic (BIPV), being one of the technologies with the potential to increase a building’s energy efficiency, is considered as a feasible method for renewable power generation to help buildings meet their own load, thus serving dual purposes. Semitransparent BIPV integration into buildings not only displaces conventional building facade materials but also simultaneously generates energy while retaining traditional functional roles. The awareness in improving building energy efficiency has increased as well as the awareness in promoting the use of clean or renewable energy technologies. In this study, semitransparent BIPV technology is reviewed in terms of energy generation, challenges, and ways to address limitations which can be used as a reference for the BIPV stakeholders.

Commercial buildings account for one third of the total electricity consumption in the United States and a significant amount of this energy is wasted. Therefore, there is a need for “virtual” energy audits, to identify energy inefficiencies and their associated savings opportunities using methods that can be non-intrusive and automated for application to large populations of buildings. Here we demonstrate virtual energy audits applied to large populations of buildings’ time-series smart-meter data using a systematic approach and a fully automated Building Energy Analytics (BEA) Pipeline that unifies, cleans, stores and analyzes building energy datasets in a non-relational data warehouse for efficient insights and results. This BEA pipeline is based on a custom compute job scheduler for a high performance computing cluster to enable parallel processing of Slurm jobs. Within the analytics pipeline, we introduced a data qualification tool that enhances data quality by fixing common errors, while also detecting abnormalities in a building’s daily operation using hierarchical clustering. We analyze the HVAC scheduling of a population of 816 buildings, using this analytics pipeline, as part of a cross-sectional study. With our approach, this sample of 816 buildings is improved in data quality and is efficiently analyzed in 34 minutes, which is 85 times faster than the time taken by a sequential processing. The analytical results for the HVAC operational hours of these buildings show that among 10 building use types, food sales buildings with 17.75 hours of daily HVAC cooling operation are decent targets for HVAC savings. Overall, this analytics pipeline enables the identification of statistically significant results from population based studies of large numbers of building energy time-series datasets with robust results. These types of BEA studies can explore numerous factors impacting building energy efficiency and virtual building energy audits. This approach enables a new generation of data-driven buildings energy analysis at scale.

Buildings account for 36% of the final energy demand and 39% of CO2 emissions worldwide. Targets for increasing the energy efficiency of buildings and reducing building related emissions is an important part of the energy policy to reach the Paris agreement within the United Nations Framework Convention on Climate Change. While nearly zero energy buildings are the new norm in the EU, the research is advancing towards positive energy buildings, which contribute to the surrounding community by providing emission-free energy. This paper suggests a definition for positive energy building and presents the framework, elements, and challenges of the concept. In a positive energy building, the annual renewable energy production in the building site exceeds the energy demand of the building. This increases two-way interactions with energy grids, requiring a broader approach compared to zero energy buildings. The role of energy flexibility grows when the share of fluctuating renewable energy increases. The presented framework is designed with balancing two important perspectives: technical and user-centric approaches. It can be accommodated to different operational conditions, regulations, and climates. Potential challenges and opportunities are also discussed, such as the present issues in the building’s balancing boundary, electric vehicle integration, and smart readiness indicators.

When global climate change becoming a problem that is getting worse nowadays, Green Buildings have become one of the major solutions to maintaining a sustainable environment. Because most of the public interpret the messages sent by their environment through visual appearance and images, This study aims to analyze the appearance effects of U.S. LEED and Taiwan EEWH Green Building rating systems by conducting surveys on the publics cognition of green building appearances and green building rating systems, and analyzing the relationship between green building appearance and environmental cognition. The results indicate that building appearance is a key judgment reference for identifying green buildings. However, there has been no significant relationships found between green building rating system and green building appearances so far, which may cause confusion as to the publics cognition and image of green buildings. Therefore, it is recommended that building's appearance image should be included in future revisions of the green building rating systems.

Tall building developments have been rapidly increasing worldwide. This paper reviews the evolution of tall building’s structural systems and the technological driving force behind tall building developments. For the primary structural systems, a new classification – interior structures and exterior structures – is presented. While most representative structural systems for tall buildings are discussed, the emphasis in this review paper is on current trends such as modeling and analysis. Consideration of site specific lateral loading due to wind or earthquake loads along with vertical gravity loads is important for finding the behavior of the tall buildings. The design of tall buildings essentially involves a conceptual design, approximate analysis, preliminary design and optimization, to safely carry gravity and lateral loads. Analysis and design of buildings for static and dynamic forces is a routine affair these days because of availability of affordable computers and specialized programs which can be used for the analysis. Finally, the future of structural developments in tall buildings is envisioned briefly

Testo completoAbstract (sommario):
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.

Purpose The purpose of this paper is to study the method of hysteresis energy distribution and maximum relative lateral displacement in buildings’ stories, under the influence of scaled records for near-fault and far-fault earthquakes. The bracings in the considered buildings’ plan are distributed in two different ways: in the first case, the braces are added in external frames of the building, and in the second case, in the internal ones. Design/methodology/approach This research first selects some steel buildings with concentric braces and studies the seismic vulnerability of buildings under different earthquakes in accordance with the concepts of input and Hysteresis energy. In order to study the impact of braces’ distribution in the building’s plan, the buildings were modeled in this study in two ways. In the first way the braces were added to the building’s external frames and in the second way in its internal ones. Findings Results show that the need for far-fault scaled records’ displacement is more than the near ones and that the resultant relative lateral displacements in buildings with external braces are more than those with internal ones. Originality/value After these studies on the way of hysteresis energy distribution, it was shown that in case of buildings with internal braces, as the building’s height increases, the share of higher stories of the hysteresis energy rises. Also, it was illustrated that hysteresis energy distribution in buildings with internal braces is more uniform than those with external ones.

One of the passive design techniques is the atrium, which can have certain effects on a building inside environment. One of the key considerations when designing a building, especially in a hot, humid area, is the ventilation component. Natural ventilation has the ability to increase a building’s energy efficiency. It can be incorporated into the design of buildings to provide indoor airflow and provide comfortable experiences for the users of the buildings. The integration of an atrium which serve an area for air movement could enhance the cooling of a building. Apart from that, it is crucial to rethink the sustainable design of public buildings by reducing the energy consumption to minimal the greenhouse gas emissions for the environment. Hence, this research was executed to study the potential of atrium design to maximize the passive cooling effect for low-rise public buildings in Malaysia. It might help people appreciate the value of using natural ventilation while creating an atrium that is suitable for a hot, humid region.

This article discusses the main concept of sustainable tourism to comprehend the terminology on definition, aspects, and main concept. Furthermore, the discussion continues how architecture plays an important part in achieving the sustainability of tourist attraction areas, and the practical ways that have been done from an architectural perspective. The discussion on the architecture subject is divided into 2 parts: the heritage buildings and new buildings, and how the architectural decision in those areas plays a part in supporting sustainable tourism. In heritage building tourism, it is important to ensure the building is in good condition physically and functional. Adaptive reuse is mainly being used to revitalize heritage buildings. In new buildings, several ways can be done to support sustainability in tourism and it's usually by designing an environmentally low negative impact building's design. If these strategies are applied in building design, it is possible to develop a tourism area that emphasizes the concept of sustainability.

The successful use of buildings requires experience, interdisciplinary knowledge and skills. Wrong decisions made by building owners or managers to implement repair projects have a negative impact on the aging of buildings, which is closely related to sustainable development. Renovation projects in more degraded buildings must be carried out to a greater extent, which has a negative impact on the environment in the form of more building waste. This article presents the results of research on the impact of refurbishment decisions on the technical conditions of buildings. The development of an optimal building renovation strategy will result in a safe and comfortable building. A comparative analysis of the impact of the choice of repair building elements on further aging changes in the building was carried out. The reason for the subject is the frequent consideration by managers of the hierarchy of building elements that improve the technical condition of the building, the reason for which is the lack of financial resources to carry out overall renovation works. To date, two refurbishment strategies have been adopted, as well as assumptions about the building’s material and structural solutions and the building’s service life. Theoretical assumptions were applied to determine the repair needs of the Bialkow palace. The method shows the superiority of the impact of structural elements over non-structural elements in improving the technical condition of a building. Developing a renovation plan with the implementation of the presented strategy will significantly reduce the technical condition of the entire building with a moderate budget, limiting the occurrence of a building disaster and the serious carbon footprint associated with the demolition of the property.

Green building refers to a structure and employing a method that's environmentally accountable and resource economical throughout a building’s life cycle. Since buildings consume nearly five hundredth of the world's total energy, inexperienced buildings, on the other hand, consume a minimum quantity of energy with the utilization of energy economical materials. Hence, location of inexperienced buildings within the close proximity would produce an inexperienced zone and supply a far healthier setting with minimum heat island result. In India there are 2 primary rating systems for inexperienced buildings: GRIHA (green rating for integrated surround assessment), LEED (leadership in energy and setting design). Green buildings compared to standard buildings appear specifically similar and conjointly within the building use, however disagree within the operational savings and considerations for human comfort and indoor and atmosphere. inexperienced buildings get pleasure from the advantages of saving 40-50% energy by reducing greenhouse gas emissions into the atmosphere; it conjointly saves concerning 20-30% of water by victimization rain gathering or gray apply techniques. It conjointly reduces VMT (vehicle miles travelled) by selecting the placement near conveyance and conveniences that helps in reduction of petrol consumption. However, on the opposite hand, inexperienced buildings face several barriers just like the high initial investment needed for construction, split incentives.

High-rise buildings represent technological, urban, and life-style trends of the modern urban landscape, yet there are limited data regarding their embodied carbon and environmental impacts, particularly when compared to low- or mid-rise buildings. Given that the projected growth of the global urban population by 2050 requires cities with higher density and potentially a greater number of high-rise buildings, it is crucial to develop a clear understanding of the embodied carbon and environmental impacts of high-rise buildings. The primary structural materials used in high-rise buildings are reinforced concrete and structural steel. As of today, over 99% of tall buildings’ structures are built from those two materials. This article utilizes a building information modeling (BIM)-based life cycle assessment (LCA) in Revit and Tally to examine the embodied carbon and environmental impacts of an actual high-rise building structure case study in Chicago that uses a hybrid concrete steel structure. The results show that the embodied carbon and environmental impacts of the high-rise building structure are dominated by the impacts of the product stage in the building’s life cycle and by concrete being the main structural material. Specifically, this study reveals that concrete constitutes a substantial 91% share of the total mass of the building structure, with a 74% contribution to the life cycle global warming potential, 53% to the acidification potential, 74% to the eutrophication potential, 74% to the smog formation potential, and 68% to the non-renewable energy usage. On the other hand, steel accounts for 9% of the building’s structure mass, estimated to constitute 26% of the global warming potential, 47% of the acidification potential, 26% of the eutrophication potential, 26% of the smog formation potential, and 32% of the non-renewable energy usage.

From the 19th century onwards, glass has been used intensively in buildings. During the design process, the importance of aesthetics is very common for architects in general. The application of glass walls as part of the building’s structure has given flexibility in design together with transparency as well as aesthetics. Structural glass systems have been used in different building types for example office, residential, educational, commercial, transportation, cultural … Beyond the high - rise and high - tech buildings, structural glass systems have been applied also to historic buildings during their conservation process. The adaption of the structural glass system and the opportunity to reuse the existing building are other important aspects to be discussed. In this article, the literature review will be formed with a brief explanation of transparency in contemporary architecture, structural glass systems focusing on ‘suspended glass systems with pre-stressed cable trusses’ (SGSPCT) which has three application methods; 1) between floor systems 2) independent body systems 3) distance bridging systems and the reusability of existing buildings. The ‘between floor system’ which is commonly used as a contemporary solution technique for historic buildings together with its effects, will also be analysed with the help of a case study, Esma Sultan Mansion. This historic building’s present glass structure will be studied to create an alternative proposal less dependent to the existing building. Another case study will be the Ballapais Abbey. Part of this gothic building (the common room) that has collapsed in the past will be analysed. An independent glass structured annex designed with SGSPCT will be proposed giving joint details of the adaptation to the existing building. This case of study is a literature analysis based on books, internet resources, articles and architectural drawings, like plans, sections and details related to the buildings. Both case studies will be proposing an alternative glass structured annex that is focusing on gained transparency and reusability in respect to the existing historic building.

Sustainable building design has gained global significance as a strategy to address environmental challenges and promote healthier living spaces. This concept is particularly relevant in Saudi Arabia, where there is a growing emphasis on integrating sustainable practices into the design and operation of buildings, especially in educational settings. Amidst the global push for sustainability in workplaces, this study’s core lies in assessing and comparing the satisfaction levels with the indoor environmental quality (IEQ) of a Saudi Arabian higher education building against those in international green buildings, considering factors that comprise thermal comfort, air quality, lighting, acoustic quality, office arrangement, furnishings, cleanliness, and maintenance. Employing the Center for the Built Environment (CBE) IEQ survey tool, a comprehensive study was conducted among the building’s occupants. A literature review and benchmarking studies complemented this to gather data on international green buildings. This study aims to assess and compare the satisfaction levels with the IEQ of a Saudi Arabian higher education building against international green buildings. The comparative analysis aims to expose the commonalities and differences in satisfaction levels, exploring how various factors influence overall satisfaction with the IEQ. The research found that there is overall satisfaction with the IEQ parameters of the building under investigation, except with two parameters: acoustics and thermal comfort. The building is generally in alignment with the IEQ of international buildings. This research is presumed to contribute significantly to sustainability initiatives in educational buildings, fostering a healthier and more sustainable workplace environment.
