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.

Building energy conservation measure (ECM) of insulation materials suitable for the domestic situation in the construction sector (passive) is established. The ECMs of insulation materials were classified into walls, roofs, and floors. Also, economic evaluation databases, which are composed of material costs, labor costs, and expenses for constructed alternatives, were built. After setting the target building and deriving the ECM list of insulation materials for the target building, the energy use evaluation and economic evaluation were performed for each constructed alternative. Based on this, the optimal building energy conservation measure of the target building was derived by applying the decision-support process.

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.

In national environment of energy conservation and emission reduction and green building in China, the development of green building has been gradually promoted in Henan Province. During the 13th Five-Year Plan period, the green building had developed for several decades in Henan Province, and the application of its technology is developing from a diversified perspective. From the analysis of the current development status, although the energy efficiency level of green building has increased by 20% compared with the 12th Five-Year Plan period, green buildings develop in varying degrees in various cities in Henan province. Due to the high cost of green building, the green building policy is not thoroughly implemented in the whole process. It is urgent to improve the current industrial structures in such a state, change the traditional architectural structures, transform and upgrade the construction industry.

Heat Preservation

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.
