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.

In this paper, we developed a new integrated analysis environment in order to thoroughly analyses urban-building energy patterns, named IUBEA (integrated urban building energy analysis), which focuses on energy modeling and analysis of a city’s building stock to support district or city-scale efficiency programs. It is argued that cities and towns account for more than two-thirds of world energy consumption. Thus, this paper explores techniques to integrate a spatial analysis environment in the field of urban building energy assessment in cites to make full use of current spatial data relevant to urban-building energy consumption and energy efficiency policies. We illustrate how multi-scale sampling and analysis for energy consumption and simulate the energy-saving scenarios by taking as an example of Greater London. In the final part, is an application of an agent-based model (ABM) in IUBEA regarding behavioral and economic characteristics of building stocks in the context of building energy efficiency. This paper first describes the basic concept for this integrated spatial analysis environment IUBEA. Then, this paper discusses the main functions for this new environment in detail. The research serves a new paradigm of the multi-scale integrated analysis that can lead to an efficient energy model, which contributes the body of knowledge of energy modeling beyond the single building scale. Findings also proved that ABM is a feasible tool to tackle intellectual challenges in energy modeling. The final adoption example of Greater London demonstrated that the integrated analysis environment as a feasible tool for building energy consumption have unique advantages and wide applicability.
