Abstract:

Green buildings are not entirely successful in achieving energy saving targets. One way of improving energy targets is to encourage occupants to adopt energy saving behaviour. To date, energy saving behaviour has been given less focus in improving green building performance than other energy saving initiatives, such as retrofitting buildings for green features. This study uses comparison case studies between green buildings and conventional buildings in New Zealand to better understand the energy saving behaviour of occupants. Questionnaires were distributed to occupants in green and conventional buildings to evaluate the extent of energy saving behaviour practiced and to identify potential strategies to encourage energy saving behaviour. The objective of this paper is to investigate the level of energy saving behaviour between green and conventional office buildings to see if people in green buildings perform better energy saving behaviour than people in conventional buildings in computer usage. The findings do show better energy saving behaviour from occupants in green buildings than occupants in conventional buildings. The paper shows why this is the case. The recommended strategies to encourage energy saving behaviour used by different buildings are also discussed. Strategies include raising education awareness on energy efficiency among the building occupants, energy saving commitments, and to have an active building manager assigned for energy related matters.

Abstract:

The external heat load of residential buildings in summer is the dominant parameter of the required cooling load and refrigeration capacity of air conditioning systems. The consumed energy of air conditioning system is proportional to the outside conditions and intensity of solar radiation. The maximum heat load of building may occur at 3 O’clock PM, although the peak of solar radiation occurs at noon. The construction materials of building is playing an important rolls of heat transmission through buildings outside walls and glazing windows. The walls thermal insulation can be effective in energy conservation by reducing the cooling load and required electrical energy. The building is constructed from common materials with 0~12 cm thermal insulation in outside walls, ceilings, and double layers glazing windows. The building heat loads are calculated for two models of walls. The optimum thickness of thermal insulation is also determined and is found between 6~8 cm for insulation of thermal conductivity of 0.039 W/m.K the energy saving is 50.45% at 6 cm insulation thickness.

Abstract:

Insulation is considered one of the effective solutions to achieve energy savings in buidings. Better insulation having low thermal conductivity contributes significantly to new construction and retrofitting existing buildings. The Energy Conservation Building Code and National Building Code of India define the prescriptive and mandatory requirements for the U-factor and R-values for different climates but the way to achieve these values is left to the designers. As none of the walling and roofing assemblies in buildings fulfill the criteria for overall thermal transmittance, the study deals with determining the thermal conductivity of sustainable walling materials and prefab roofing technologies as well as insulating materials using Guarded Hot-Plate Apparatus. The MATLAB program is developed for computing the U-values and for predicting the desired retrofit insulation thicknesses to make different materials and roofing assembly combinations comply the Code requirements in different climatic regions of India. The results of the study are used for computing the performance with and without insulation using DesgnBuilder software for improving energy efficinecy of the buildings in composite climate in India.

Abstract:

Urban population has been increased rapidly and caused such urban problems as shortage of housing and traffic jam, and the continuously expanding buildings have resulted in strong impact on global resource consumption and environmental pollution. Green building materials are the basic guarantee to the quality and service life of buildings, the material carrier to realize various functions of buildings and also the foundation and support to develop green buildings. Based on the coherence and relevance of assessment on full life cycle of buildings and building materials, the influence of exterior window selection on carbon emission of buildings was analyzed in aspects of the initial stage (production, consumption and transport of building materials) of carbon emission of buildings, i.e. the intrinsic energy per unit product, operation, demolition and treatment. The comprehensive assessment was also established, and the selection of green building materials was investigated for exterior windows based on the reduction of energy consumption during full life cycle of buildings by combining such indicators as the usability, durability, fireproofness, environmental protection and functionality of exterior windows. It solved the puzzles of architects on selection of building materials and the puzzles of building material manufacturers on demand of green buildings. The selection of green building materials on green buildings was promoted and the realization of the goal of "green buildings" also assisted.

Abstract:

ABSTRACT Urban building energy analysis has attracted more attention as the population living in cities increases as does the associated energy consumption in urban environments. This paper proposes a systematic bottom-up method to conduct energy analysis and assess energy saving potentials by combining dynamic engineering-based energy models, machine learning models, and global sensitivity analysis within the GIS (Geographic Information System) environment for large-scale urban buildings. This method includes five steps: database construction of building parameters, automation of creating building models at the GIS environment, construction of machine learning models for building energy assessment, sensitivity analysis for choosing energy saving measures, and GIS visual evaluation of energy saving schemes. Campus buildings in Tianjin (China) are used as a case study to demonstrate the application of the method proposed in this research. The results indicate that the method proposed here can provide reliable and fast analysis to evaluate the energy performance of urban buildings and determine effective energy saving measures to reduce energy consumption of urban buildings. Moreover, the GIS-based analysis is very useful to both create energy models of buildings and display energy analysis results for urban buildings.

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.

with the vigorous development of construction in our country, the proportion of the building energy consumption in total is increasing step by step, especially the 1980s existing buildings, the vast majority of them failing to take any insulation measures, the energy consumption of them is several times or even ten times to new buildings, therefore, in recent years, energy saving reconstructions of existing buildings have paid more and more attention. This paper takes a typical office building which was built in sunan region as an example, using some external thermal insulation materials such as rigid polyurethane foam plastics, polyurethane composite board and energy saving design software BECS to imitate energy saving reconstruction. Besides, the economy of each scheme of energy saving reconstruction was also analyzed. The results show that, energy saving reconstruction can greatly reduce the energy consumption of existing buildings, and bring good economic benefits, at the same time, it also can improve indoor comfort and working conditions, and can generate significant social benefits.

Abstract:

Without any doubt, one of the most worldwide challenging and controversial issues in the current century is the energy problem. In most countries, the increase of energy consumption, especially in building, has made energy saving and efficiency strategies important target for energy policies. In general, there are many ways to save energy. The most common method of economizing is within culturalization. For such purpose, building energy management system (BEMS) is considered as the latest idea of energy. Having a dynamic environment, smart buildings are affordable by the integration of four main elements: systems, structure, service, management, and the relationship between them. Intelligent buildings provide these benefits through intelligent control systems. In this paper, while introducing the energy management in buildings, it studies their applications and also their effects on management and optimization of energy consumption. The office building in San Francisco, USA with 66,943 ft2 area is considered as a case study for this research. Energy consumption is reduced 50 percent by implementing BMS in this building.

Abstract:

Electric energy consumption shares a great portion of commercial building energy. Electric energy saving is essential to reduce total energy consumption in commercial buildings. To draw energy saving methods, it is necessary to monitor real energy consumption patterns and analyze the results. We monitor the lighting and non-lighting energy consumption of eleven zones in a real working office building every fifteen minutes during eleven months. We observe and analyze the monthly and daily energy consumption patterns of all zones and draw several feasible energy saving methods. Moreover, the lighting and occupancy are monitored simultaneously in detail to investigate the unnecessary energy consumption. It shows the possibility of a great amount of energy saving. Because we analyze the energy consumption patterns in all zones, the drawn energy saving methods are applicable to the current building with some added infrastructure and expandable to other similar office buildings. Our result is expected to contribute to reducing the energy consumption in buildings.

Abstract:

Building energy conservation has gained tremendous interest since the 1970s energy crisis. Building energy standards have been established as prescribed guidelines for energy savings in buildings worldwide, among which those from China and the United States of America (USA) are representative of their advanced concept, comprehensive content and prospective guidance. This paper collected and generalized the main building energy standards in China (GB50189, JGJ26, JGJ134 and JGJ75) and the USA (ASHRAE 90.1), in terms of updating history, current status, energy saving potential and future development directions. Furthermore, a qualitative and quantitative comparison of the selected standards was performed. The results show that China has a more intact and comprehensive building energy standard system, better implementation, higher improvement in energy saving rates, and a more perspicacious upgrade towards zero-energy target, which results in effective energy savings in buildings. The ASHRAE standards have more fixed chapter framework, integrity and independence between versions, more detailed classification of building envelope and HVAC systems but less effective energy-saving effect and relatively poor implementation. The actual efficiency of standards in building energy saving is synthetically determined by the standard content, efficient implementation and explicit guidelines for future development, which is achieved through four main procedures. Based on the results, recommendations have been proposed for the future development of building energy standards with the ultimate goal toward zero energy buildings.

Abstract:

Existing buildings energy-saving renovation is an important means to cope with global warming and an essential component of achieving China’s energy conservation and pollution emissions reduction strategy goals. The development of the energy-saving renovation market is closely related to its influencing factors, which determine the reasons and conditions for the development of the system; therefore, it is necessary to study the influencing factors of energy-saving transformations. System dynamics was applied to explore the feedback relationship between the service subsystem, the demand market subsystem, and the market regulation subsystem. Analysis was performed for the intrinsic influencing factors of the development of the existing building energy-saving renovation market and the interaction law of feedback relationship. This paper discusses the basic characteristics of government incentives, Energy Service Company (ESCO) technology innovation, ESCO’s revenue, and owner’s awareness to promote the development of the existing building energy-saving renovation market. Base on those, it puts forward suggestions for promoting the market development of existing buildings energy-saving reconstruction. The findings provided a theoretical basis and guiding role for the Chinese government to formulate support policies for existing building energy-saving renovation. At the same time, it also provides reference for other countries to develop existing buildings energy-saving renovation market.

Abstract:

Energy-saving buildings have been constructed based on the German energy-saving passive building codes in China these years. However, the energy-saving system of passive building may not suitable for the hot-in-summer and cold-in-winter district in China. In this regard, researches and applications of the external heat-preservation technique using building walls is presented. Furthermore, the comparison between the simulation of energy-saving and pertinent data from engineering application is also shown in this paper. The investigations reveal that it is not advisable to adopt the existing passive building for the hot-in-summer and cold-in-winter area in China based on the German energy-saving codes using external walls. The study suggests that heat transfer index of the energy-saving buildings needs more investigations according to different climate divisions.

Abstract:

To fight global warming, we must understand what our energy options are. By far the most important option is efficiency, which is the easiest, quickest, and least expensive way to fight global warming. The most efficient way to decrease the energy consumption of buildings is to increase the insulation of thermal envelopes such as the roof and exterior walls. Globally, many countries have targets to reduce building energy consumption and to provide energy efficient buildings such as passive house and zero energy buildings. This paper presents the applications of high-efficiency insulations for passive house and zero energy buildings. Insulation cost is a small percentage of the total construction cost, but the saved energy cost is large making payback periods short. Considering the possibility of rise of oil price and the exhaustion of fossil fuel, insulation should be added beyond the level that any building insulation code requires.

Abstract:

In the context of the increasingly severe energy crisis and global warming, green buildings and their energy-saving issues are being paid more attention in the world. Since envelope optimization can significantly reduce the energy consumption of green buildings, value engineering (VE) technology and building information modeling (BIM) technology are used to optimize the envelope of green buildings, which takes into account both energy saving and life cycle cost. The theoretical framework of optimization for green building envelope based on BIM-VE is proposed, including a BIM model for architecture, a life cycle cost analysis model, energy-saving analysis model, and a value analysis model. In the life-cycle cost model, a mathematical formula for the life-cycle cost is established, and BIM technology is used to generate a bill of quantity. In the energy-saving analysis model, a mathematical formula for energy saving is established, and BIM technology is used for the building energy simulation. In the scheme decision-making sub-model, VE technology integrating life cycle cost with energy saving is used to assess the envelope schemes and select the optimal one. A prefabricated project case is used to simulate and test the established methodology. The important results show that the 16 envelope schemes make the 16 corresponding designed buildings meet the green building evaluation standards, and the optimal envelope scheme is the “energy-saving and anti-theft door + exterior window 2+ floor 1+ exterior wall 1 + inner shear wall + inner partition wall 2 + planted roof” with the value 10.80 × 10−2 MW·h/ten thousand yuan. A significant finding is that the value generally rises with the increase of energy-saving rate while the life cycle cost is irregular with the increase of energy-saving rate. Compared with previous efforts in the literature, this study introduces VE technology into architectural design to further expand the current boundary of building energy-saving theory. The findings and suggestions will provide a valuable reference and guidance for the architectural design industry to optimize the envelope of green buildings from the perspective of both energy saving and life cycle cost.

Abstract:

The research is to explore the changes in solar heating buildings under energy-saving structural design. This paper analyzes the changes in solar heating buildings under energy-saving structural design by constructing a numerical simulation method. It mainly studies the effects of the space temperature of the house, different thermal insulation methods, and wall thermal resistance on solar heating buildings. The energy-saving structural design mainly includes expanding the area of exterior windows, increasing heat retainers, adopting energy-saving walls, and improving the building envelope. The results show that after the energy-saving structural design, the indoor temperature of the solar heating building after the renovation has been greatly increased, with an average increase of about 6 ?C. Compared with the external insulation and internal insulation modes, the solar heating building under the sandwich insulation mode has the best effect, and the room temperature increases the most. Also, it shows that the east wall, west wall, and north wall of the building are increasing the energy saving per unit area of the wall as the wall thermal resistance increases. The difference is that the increasing range of the north wall has significant advantages over the east wall and the west wall. The energy-saving structural design for solar heating buildings under the numerical simulation method has significantly improved the utilization efficiency of solar energy. It reduces the consumption of traditional fossil resources and improves the quality of the environment. This paper?s research has a positive effect on subsequent research.

Abstract:

Purpose Sustainable retrofitting of aged buildings plays a significant role in reducing energy demands and greenhouse gas emissions. This study aims to assess the performance and effectiveness of energy retrofit measures (ERMs) for an archetype of aged multi-storey residential buildings. Design/methodology/approach The methodology consists of three parts, namely, a desktop study including the selection of a case-study building and identification of ERM options for the building; development of a computer model to simulate the building’s energy use in the baseline scenario and different scenarios of ERMs; and evaluation of the ERMs based on energy-saving rate. Findings Among the 13 ERMs tested, lighting-related ERMs were found to be optimal measures while window fin is the least suitable option in terms of energy saving. Based on the research findings, a two-level retrofitting framework was developed for aged multi-storey buildings. Research limitations/implications Future studies may take a similar approach of this study to develop retrofitting frameworks for other types of buildings, and further research paper can be extended to study retrofitting for buildings in a district or a region. Practical implications The findings of this study can serve as a reference for building owners to select effective ERMs for aged multi-storey buildings, which invariably exist in developed cities. Originality/value This study presents a pioneering work where an energy model and a building archetype were used to analyze the energy savings of a variety of ERMs that are applicable to aged multi-storey buildings.
