External wall has great impact on building energy conservation. Developing composite wall is direct way to improve the situation of building consumption. In this study, the importance of building energy conservation was analyzed. Several types of composite thermal insulation wall were listed and their advantages and disadvantages were discussed. Self-insulation composite wall has unique superiority, especially in hot summer and cold winter zone. Meanwhile, the application prospect of composite wall with combinations of insulation coating of high reflectivity and silt sintered porous brick was introduced. Finally, combining regional character, some suggestions were proposed on the further development of China’s composite wall in hot summer and cold winter zone.

Building insulation is an important part of building energy conservation. The heat insulation coating preapred from modified expanded perlite has been a potential building thermal insulation material. In this paper, aerogel was filled into the pores of expanded perlite by vacuum impregnation method to produce aerogel-modified expanded perlite at ambient pressure. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and N2 adsorption–desorption techniques. The results revealed that aerogel could be well filled into the pores of expanded perlite, and the resultant aerogel-modified expanded perlite possessed nanoporous structure with higher specific surface area of 196 m2·g-1, and low thermal conductivity of 0.063 W·m-1·K-1 less than that of expanded perlite by 13.3%. Heat insulation coatings prepared from aerogel-modified expanded perlite had good thermal insulation effect, indicating that the product showed potential aplication in the field of building energy conservation.

Mateial selection technology for green building is an important support of green building development. Aiming at the realization of green building energy conservation, the green building material selection evaluation model was proposed integrating double elements - energy contained in a unit product of building material and energy saveing brought to the building operation in the service process of building material. Taking three categories of thermal insulation materials - polyphenyl board, rock wool board and polyurethane rigid foam board as examples, the relative relationship was calculated and analyzed between energy contained in a unit product of three categories of thermal insulation materials and energy saving in building operation brought by them respectively, and finally a conclusion draws from that: based on building energy conservation, polyphenyl board is a suitable product to realize green building material selection.

With the speeding up of urbanization and growth of national economy, housing industry has developed rapidly in recent years, the residential building energy saving problem has been increasingly outstanding, according to the study, the future China building energy consumption ratio will rise to about 35%. At present, building energy conservation has become one of the recognized effective ways to solve the increasingly serious energy problems. Through the study of the near zero energy building in the hot summer and cold winter area,the thermal comfort of the near zero energy building was satisfied by using the semiconductor cold and hot wall system,the practical effect and operation parameters of the semiconductor cooling wall were given. It was presents a series of Suggestions and improvement Suggestions for the research and energy conservation work of near zero energy buildings in hot summer and cold winter area.

With the acceleration of globalization, industrialization and informatization, the consumption of energy resources is increasing, and the building energy consumption accounts for about 30%, so the building energy conservation has become an important part of energy conservation and emission reduction. At the same time of economic development, we should reduce building energy consumption and do a good job in building energy conservation [1], and put forward the following ways: the improvement of building’s own heat preservation and insulation performance; the improvement of energy utilization system efficiency such as electricity and heating; the development and utilization of new energy; and the proper management of energy utilization equipment system. Among them, the most effective way is to improve the thermal insulation performance of the building itself. The thermal insulation of enclosure and the air tightness of doors and windows are two important parts of thermal insulation. According to the relevant data [2], the heat loss of enclosure structure accounts for 40-50% of the building energy consumption, and the heat loss of wall structure accounts for about 70%. Therefore, the improvement of the thermal insulation requirements of the wall structure plays a huge role in building energy conservation In this paper, the experimental research on the exterior wall thermal insulation board of decoration and heat preservation integration is carried out. The influence of fly ash content, asbestos fiber content, composite active activator, waterproof agent and other additives on the physical properties of fiber-reinforced fly ash / cement board is discussed. The optimal content of various factors is determined and its mechanism is analyzed. The optimum proportion of fiber reinforced fly ash / cement board was determined by orthogonal test.

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.

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.
