Abstract:

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.

Abstract:

Purpose Today, about 30 per cent of European existing buildings can be entitled as “historical buildings”. Nowadays, their energy retrofit is important to reach the ambitious European CO2 emissions’ reduction objectives. The purpose of this paper is to outline a methodology to investigate the potential energy savings and the enhancement of historical buildings’ liveability by acting only on their operation, so that the building fabric could be maintained as much as possible as the original evidence. Design/methodology/approach The paper describes the framework’s theoretical phases and their application in two real case studies. The methodology was conceived with a pre-test and post-test design approach. Findings The research demonstrated that the elaborated methodology is flexible and allows the adoption of different energy retrofit strategies for the different cases. Research limitations/implications Limitations arise out of the circumstance that the methodology is based on occupants and technicians willingness to engage in the strategies, so it is not possible to quantify its efficacy ex ante. Practical implications Practical implications can be found in the way of addressing energy retrofit strategies through a user-centric approach with minimum impact on the building itself. Social implications At the same time, the methodology has a strong social aspect with its potential to change people’s attitudes towards energy usage and behaviour. Originality/value This study not only represents the first attempt of applying a systematic energy retrofit strategy based on occupants and technicians behavioural change in historic buildings, but also is one of the first studies dedicated to occupants’ comfort and behaviour assessment in this context.

Abstract:

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.

Abstract:

The study and design of energy conservation has gradually become a hot and key issue in architecture. One of the core contents of such concepts as green architecture, ecological architecture, sustainable architecture, organic architecture is how to reduce high energy consumption of buildings. The study of building energy conservation has been carried out in subjects of architectural thermal engineering and energy conservation for almost 30 years. The central and local governments have set up special management agencies and departments of building energy conservation; building research institutes at all levels and numerous universities have set up research institutions for study of building energy conservation and issued a series of policies and regulations and technical standards, which received an enthusiastic response from industrial circles and have produced tens of billions of production. However, more than 95% of the existing buildings and more than 80% of new buildings of China belong to those with high energy consumption. The paper tries to interpret the deep reason of the phenomenon from the aspects of society, technology, etc. for discussion of researchers in the field of architectural thermal engineering and energy conservation.

Abstract:

The expanding commercial building sector and urbanization in India leads to an increase in demand of energy many folds. Consequently, it is the need of the current scenario to define some regulatory regime or policy to harness the enormous potential of energy savings. Under the Energy Conservation Act 2001, the Government of India under the Bureau of Energy Efficiency launched the Energy Conservation Building Code (ECBC) on a voluntary basis. ECBC sets the standards of minimum energy performance for “large commercial buildings. These norms were for both new and existing buildings. Retrofitting of existing buildings offers noteworthy opportunities for reducing global energy consumption and greenhouse gas emissions. This paper provides a systematic approach to review the application of energy conservation building codes in existing buildings and identification of the best retrofit strategies to stimulate the implementation of ECBC in the country.

Abstract:

Accompanying efforts worldwide to deploy sustainable building technologies shows a pressing need for expanded research on occupant behavior. Discourse is lacking concerning drivers of occupant behavior for energy conservation, especially in the case of commercial buildings. This paper explores potential determinants of occupant behavior for energy conservation in commercial buildings. This is investigated in a case study of a two-month energy conservation competition involving eight office buildings at the Oak Ridge National Laboratory. Four buildings achieved energy savings based on the previous year’s baseline. Potential challenges and success factors of occupant behavior for energy conservation during the competition were explored based on an explanatory research design incorporating energy data, participant interviews, and surveys. The findings suggest that both social and technological aspects may be important drivers of energy conservation. The determinants of occupant behavior for energy conservation in commercial buildings suggested for further research include bottom-up involvement, stakeholder relationship management, targeted information, real-time energy visualization, and mobile social platforms. This paper presents initial implications, with a need for further research on these propositions and on their impacts on occupant behavior. This paper aims to contribute to both academia and practitioners in the arena of commercial building sustainability.

Abstract:

Energy conservation and human thermal comfort enhancement in buildings is a topical issue of modern architecture and construction. The innovative solution of this problem makes it possible to enhance building ecological and maintenance safety, to reduce hydrocarbon fuel consumption, and to improve life standard of people. The requirements to increase of energy efficiency in buildings should be provided at all the stages of building's life cycle that is at the stage of design, construction and maintenance of buildings. The research purpose is complex analysis of energy efficiency in operated high-rise residential building. Many actions for building energy efficiency are realized according to the project; mainly it is the effective building envelope and engineering systems. Based on results of measurements the energy indicators of the building during annual period have been calculated. The main reason of increase in heat losses consists in the raised infiltration of external air in the building through a building envelope owing to the increased air permeability of windows and balcony doors (construction defects). Thermorenovation of the building based on ventilating and infiltration heat losses reduction through a building envelope allows reducing annual energy consumption. Energy efficiency assessment based on the total annual energy consumption of building, including energy indices for heating and a ventilation, hot water supply and electricity supply, in comparison with heating is more complete. The account of various components in building energy balance completely corresponds to modern direction of researches on energy conservation and thermal comfort enhancement in buildings.

Abstract:

The construction industry has witnessed an increase in the use of digital tools and smart solutions, particularly in the realm of building energy automation. While realising the potential benefits of smart cities, a broader scope of smart initiatives is required to support the transition from smart buildings towards smart neighbourhoods, which are considered critical urban development units. To support the interplay of smart solutions between buildings and neighbourhoods, this study aimed to collect and review all the smart solutions presented in existing scientific articles, the technical literature, and realised European projects. These solutions were classified into two main sections, buildings and neighbourhoods, which were investigated through five domains: building-energy-related uses, renewable energy sources, water, waste, and open space management. The quantitative outcomes demonstrated the potential benefits of implementing smart solutions in areas ranging from buildings to neighbourhoods. Moreover, this research concluded that the true enhancement of energy conservation goes beyond the building’s energy components and can be genuinely achieved by integrating intelligent neighbourhood elements owing to their strong interdependencies. Future research should assess the effectiveness of these solutions in resource conservation.

Abstract:

With the rapid development of large-scale public buildings, energy consumption has increased, of which the energy consumption of comprehensive commercial buildings can reach 10~20 times the common building energy consumption, and has great energy saving potential. In this paper, a large comprehensive commercial building in Chengdu is taken as an example to analyze the energy consumption through the actual energy consumption data, viewed from the energy-saving and emission-reduction and static investment payback period point. The results show that the energy saving rate of the building can be achieved by 32.64%, the emission reduction is 6196.52 t CO2 per year, and the investment recovery period is only about 0.90 years, which provides a reference for similar buildings.

Abstract:

The residential sector is one of the largest energy-consuming sectors in Taiwan. Taiwan applies building codes and appliance standards to reduce the total energy demand for buildings, especially for façade design. Some research studies demonstrate that design decisions regarding the envelope shape have a direct effect on a building’s energy performance. This paper presents a comparative study of four façade design strategies for low-rise residential buildings by combining energy performance and architectural creativity. The research aims to provide insights for Taiwan’s building designers and energy policymakers and to provide an overview of façade standards for residential buildings in urban areas that is not only innovative in design but also has an energy-saving potential. The approach used in this research combined the overhang and side fin shading design with an open plan, which allows for optimum daylight exposure across all spaces in order to reduce energy consumption.

Abstract:

In the face of extreme climate, Net Zero Energy Buildings (NZEBs) represent a very high standard of building energy conservation. The design of NZEBs requires continuous design improvement and analysis in a decision-making process that seeks to meet energy conservation goals. This paper recommends the use of green Building Information Modelling (BIM) to support the design of zero-energy buildings. The design of NZEBs requires two sets of tasks: First, it requires determination of whether the building will offer high-energy efficiency, and, second, it lacks the installation of sufficient renewable energy equipment to meet the building’s load needs. After drawing on the spirit of the United States’ Leadership in Energy and Environmental Design and considering the current situation in Taiwan, this paper recommends the use of electricity Energy Usage Intensity as a measurement unit providing a holistic indicator of energy usage and takes optimized energy performance as a performance target for various solutions. This study demonstrated procedural steps in the application of green BIM and analyzed restrictions on the implementation of green BIM to the analysis of NZEB design.

Abstract:

In the twenty first century, the world is witnessing an unprecedented energy transition. This sustainability-driven transition, also termed the sustainable energy transition or low carbon transition, has four major dimensions: decarbonisation, decreased use, decentralisation, and digitalisation. Decarbonisation and decreased use of energy are already well established dimensions of the sustainable energy transition. Decreased use of energy through energy conservation and management (ECM) offers wide ranging benefits across all energy consuming sectors, i.e., buildings, industry, and transportation. The building sector, accounting for almost 40% of the world’s total energy consumption, is particularly conducive to ECM. Estimates suggest that with the reliable and commercially available solutions, energy demand in both new and existing buildings can be reduced by 30 to 80%.

Abstract:

Environmental concerns and growing energy costs raise the importance of sustainable development and energy conservation. The building sector accounts for a significant portion of total energy consumption. Passive cooling techniques provide a promising and cost-efficient solution to reducing the energy demand of buildings. Based on a typical residential case in Hong Kong, this study aims to analyze the integration of various passive cooling techniques on annual and hourly building energy demand with whole building simulation. The results indicate that infiltration and insulation improvement are effective in regard to energy conservation in buildings, while the effectiveness of variations in building orientation, increasing natural ventilation rate, and phase change materials (PCM) are less significant. The findings will be helpful in the passive house standard development in Hong Kong and contribute to the further optimization work to realize both energy efficiency and favorably built environments in residential buildings.

Abstract:

Public buildings such as colleges and universities in Chengdu can be studied from the aspects of the main factors influencing buildings’ energy consumption. This study analyzed the indoor thermal environment of the buildings and characteristics of their palisade structures, with their thermal performance and energy consumption, as main influencing factors of energy consumption. In the present study, these public buildings have been considered as the research object, their data has been measured through field investigation and theoretical analysis, numerically simulated- based on the actual features- and compared by computer simulation to describe the influence of thermal performance of different envelope structures on energy consumption. Also, the relationship between different thermal performance indexes and energy consumption is established. The advantage of this study is mainly to our green and energy-saving society. “Building a conservation-oriented and environmentally friendly society” is a basic state policy of China. Due to their high energy consumption ratio and greater difficulty in energy conservation, public buildings are the key places in emission reduction. The selection of appropriate green building technology is the key to sustainable development of public buildings.

Abstract:

Under the requirement of energy savings and emission reduction in China, building energy consumption, which occupies a rising proportion of the total energy consumption in society, has become the focus of energy conservation research. Public buildings with a high-energy consumption level have become the most important part of energy conservation research. It is of great practical significance and social value to study energy conservation in large public buildings. In this paper, a large office building is taken as an example. First, a simulation model is constructed by using the energy consumption simulation analysis method, and the reliability of the model is verified by a comparison with the actual energy consumption. Second, based on the model, the thermal design parameters of six building envelope structures, including the external wall heat transfer coefficient, are analyzed in the order of energy-saving sensitivity. Based on the results of the sensitivity analysis, suggestions for each factor are presented. Finally, considering the mutual influence of each parameter on the building energy consumption, the orthogonal design method is used to arrange the test, and the optimal scheme combination of the energy-saving effect is analyzed, which can provide decision support for the energy saving of public building envelopes.

Abstract:

Building energy performance benchmarking increases awareness and enables stakeholders to make better informed decisions for designing, operating, and renovating sustainable buildings. In the era of nearly zero energy buildings, the embodied energy along with operational energy use are essential for evaluating the environmental impacts and building performance throughout their lifecycle. Key metrics and baselines for the embodied energy intensity in representative Hellenic houses are presented in this paper. The method is set up to progressively cover all types of buildings. The lifecycle analysis was performed using the well-established SimaPro software package and the EcoInvent lifecycle inventory database, complemented with national data from short energy audits carried out in Greece. The operational energy intensity was estimated using the national calculation engine for assessing the building’s energy performance and the predictions were adapted to obtain more realistic estimates. The sensitivity analysis for different type of buildings considered 16 case studies, accounting for representative construction practices, locations (climate conditions), system efficiencies, renovation practices, and lifetime of buildings. The results were used to quantify the relative significance of operational and embodied energy, and to estimate the energy recovery time for popular energy conservation and energy efficiency measures. The derived indicators reaffirm the importance of embodied energy in construction materials and systems for new high performing buildings and for renovating existing buildings to nearly zero energy.

Abstract:

The article discusses technical proposals for energy saving in high-rise buildings based on the use of “green” energy. These include: the use of hybrid wind and solar power plants and vortex wind-driven power plants with a vertical axis to utilize both the energy of horizontal wind flows at height level and the energy of ascending airflows. The general principles of building hybrid wind and solar power plants for energy conservation in high-rise buildings are set forth based on the analysis of prior art. These include the following: to ensure safe operation and the absence of tele-interruptions, it is advisable to close the wind turbines with a dome design that has a cavity that captures the wind flow; to ensure environmental friendliness and ease of management, it is advisable to use a variety of vertical vortex wind turbines of modular design; for efficient use of solar energy, it is advisable to integrate photovoltaic cells into the outer structure of the dome; To reduce the cost of the project, it is advisable to use the existing high-rise buildings. A vortex wind power installation is proposed, which allows the use of small winds and low-potential thermal flows, to reduce low-frequency vibration, to increase the stability and efficiency of use of wind energy with ease of installation, maintenance and repair.

Abstract:

Large-scale public buildings have high energy density, which take big part of the gross energy consumption in buildings in China. It is still in attempting stage about the strategy of energy conservation in air conditioning systems. The objective of this study is to investigate that how to appropriately divide central air conditioning system zoning by using simulation software to calculate the basis dynamic temperature and load in typical large-scale public buildings. Effects of weather conditions, building envelope conditions and building structure on large-scale public building energy consumption were analyzed in this simulation. The results show that the building load is the fundamental factor involved in air conditioning system zoning. Surplus heat recovery in inner zone is also recommended to maintain inner zone comfort and energy conservation. This work provides the theoretical and technological basis for study on central air conditioning system zoning and thermal comfort for large-scale public building.

Abstract:

Existing buildings consume most of our non-transportation related energy and are a major contributor to the emission of greenhouse gases. Improving their energy efficiency by applying energy conservation measures (ECMs) remains a major challenge. This paper presents computational tools developed to screen office buildings for retrofit and to select specific ECMs for each building. This selection process accounts for climate, occupancy, building operation, heating and cooling systems, distribution systems, envelope properties, building geometry, and cost of ECMs. The tools screen the complete building set for optimal retrofit opportunities. The methodology adopted in developing the computational tools includes characterization of the office building stock into a manageable set of archetypes; simulation of building operation using specific occupancy characteristics and local climate data; development of energy prediction models for lights, equipment, pumps, fans, domestic hot water, chillers, and boilers; and application of present value analysis to evaluate the cost effectiveness of ECMs.

Abstract:

Energy is the basic ingredient for economic growth and development [Lorde, et al. (2010)]. Presently demand for energy has significantly increased due to the overall expansion of economic and industrial activity in all important economic sectors e.g. industry, agriculture, and services. In addition to the expansion of economic activity and subsequent increase in energy demand at industrial level, population growth and increased consumption are also adding to the demand for energy [OECD (2011)]. In other words, modern economy has become highly dependent on energy resources. In order to meet the increased energy demand and ensure its sustainable supply, there is a need to have strong and robust plans with all options to consider at various levels.

Abstract:

Building energy codes are key policy tools for improving building energy efficiency by defining the minimum requirement for the energy performance of new buildings. In Korea, the building energy code was focused on prescriptive criteria for a long time but is now gradually introducing performance criteria. However, switching to performance criteria is not straightforward because of the resistance of the market to abandoning the well-consolidated prescriptive criteria. The objective of this study is to derive appropriate measures to strengthen the prescriptive criteria and the performance criteria, considering both the energy-saving effect and the economic efficiency for new office buildings and educational buildings to increase the market acceptance of the building energy codes. To this end, the energy-saving effects of reference buildings resulting from the reinforcement of the prescriptive criteria in the past have been first analyzed. Then, based on the collected energy performance parameters and cost data, the economic efficiency relative to the energy saving deriving from the application of passive and active energy conservation measures (ECMs) were analyzed, and future building energy code’s reinforcement measures were derived.
