Building Energy Conservation

Recent years have seen the improvement of economic conditions and living standards of Chinese rural residents. But the problems of waste and pollution have occurred in rural housing construction for heating, lighting and ventilation, damage of ecology, etc. As a result, it is necessary to push energy efficiency in rural housing construction in China. In this paper, the problems existing in rural housing construction are first described, and then the strategies and measures to improve the energy conservation in rural residential buildings are put forward. The solutions to the energy conservation in rural residential buildings in China are those government should play the strengthen leadership role, developing the market of building energy conservation and developing technical foundation s and technological innovations.

Total Energy Consumption

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.

Depth Study

Building Energy Conservation, especially the research about residential building energy in face of the worldwide energy crisis is particularly urgent. At present, various countries have an in-depth study of the residential building energy to explore different methods, new building materials, and new technology(such as new thermal windows and doors), as well as the use of new energy has been put more attention to in energy conservation field. Comparing the residential buildings between domestic and overseas countries’ progress about related technologies, we could find some evolution and look to the prospects for the future in energy-saving field. We took a domestic project that used energy-saving technology as a practical example, and then made a simple overview of the current energy situation in China so as to get a glimpse of the development about residential building energy-saving. Finally, the article provided some comments about this topic in sustainable view.

Review Study

Energy consumption in buildings depends on several physical factors, including its physical characteristics, various building services systems/appliances used, and the outdoor environment. However, the occupants’ behavior that determines and regulates the building energy conservation also plays a critical role in the buildings’ energy performance. Compared to physical factors, there are relatively fewer studies on occupants’ behavior. This paper reports a systematic review analysis on occupant behavior and different modeling approaches using the Scopus and Science Direct databases. The comprehensive review study focuses on the current understanding of occupant behavior, existing behavior modeling approaches and their limitations, and key influential parameters on building energy conservation. Finally, the study identifies six significant research gaps for future development: occupant-centered space layout deployment; occupant behavior must be understood in the context of developing or low-income economies; there are higher numbers of quantitative occupant behavior studies than qualitative; the extensive use of survey or secondary data and the lack of real data used in model validation; behavior studies are required for diverse categories building; building information modeling (BIM) integration with existing occupant behavior modeling/simulation. These checklists of the gaps are beneficial for researchers to accomplish the future research in the built environment.

Consumption System

This paper analyzes the characteristics and composition of the energy consumption system of the building from the perspective of systematic energy conservation and presents the systematic framework of the consumption model. Based on the framework, the paper focuses on how to establish a building energy consumption assessment system, find the energy efficiency index system and assessment approaches, and apply the results directly into building energy conservation and emission reduction. It not only facilitates greatly the overall and efficient management of the energy consumption system of the building, but also serves as another new approach to achieve energy conservation and emission reduction.
