High Energy Consumption

The study and design of energy conservation has gradually become a hot and key issue in architecture. One of the core contents of such concepts as green architecture, ecological architecture, sustainable architecture, organic architecture is how to reduce high energy consumption of buildings. The study of building energy conservation has been carried out in subjects of architectural thermal engineering and energy conservation for almost 30 years. The central and local governments have set up special management agencies and departments of building energy conservation; building research institutes at all levels and numerous universities have set up research institutions for study of building energy conservation and issued a series of policies and regulations and technical standards, which received an enthusiastic response from industrial circles and have produced tens of billions of production. However, more than 95% of the existing buildings and more than 80% of new buildings of China belong to those with high energy consumption. The paper tries to interpret the deep reason of the phenomenon from the aspects of society, technology, etc. for discussion of researchers in the field of architectural thermal engineering and energy conservation.

Building Energy Conservation

Building energy conservation has become the worldwide tendency since the mid-1970s. The Theory of Sustainable Development raised in 1990s as well as the deterioration of ecological environment made the building energy conservation became the international focus all over the world. China is a country with high energy consumption and large population and the percentage of its building energy consumption has reached about 25% on total energy consumption. The energy conservation condition of building external wall is one of the direct influencing factors of thermal comfort of indoor environment. However, greening is a kind of natural sunshade of the nature. The key to the study is how to improve the temperature of building walls and thermal comfort of indoor environment by the way of greening sunshade of external walls.

The development of human society is a non-stop gear, and the way we use energy is about the future. How to use resources reasonably and effectively is the pressure we face. The increase in population is the problem of resource allocation—insufficient inventory of traditional energy sources. Economic development is a double-sided blade, and ecological environmental protection is our focus. Research and development of new energy and renewable energy is a way to block dependence on traditional energy sources. It is the inevitable way for human beings to coexist harmoniously with ecology in the future. The development of the construction industry has also brought about a greater proportion of energy consumption. Building heating, ventilation, air conditioning and lighting account for about one-third of the total energy consumption. The carbon dioxide emissions of the construction industry account for more than half of the total emissions, which has a great impact on the environment. The broad definition of building energy conservation is proposed, and the significance of using new energy to building energy conservation is expanded from the perspective of macro environment, including the use of integrated energy, solar energy, and energy islands to achieve zero energy consumption in building energy conservation. The construction has effectively promoted the development of zero energy consumption in terms of the life cycle and environmental protection.

Abstract The situation of high energy consumption in construction industry is becoming increasingly severe, which hinders the sustainable development of world economy, society and environment. Building energy conservation reconstruction is urgent. The long-term and effective promote of buildings energy conservation reconstruction depends on the market development. However, its external characteristics and public goods attributes determine it is necessity of implementing incentives. The incentives of the buildings energy conservation reconstruction market development not limited in policy incentives, involving multiple influencing factors, which are interrelated and complex systems engineering. Therefore, it is necessary to integrate many factors into a coordinated dynamic system. This paper uses literature analysis method and expert interview method to identify the factors that affect incentives of buildings energy conservation reconstruction market development. In this study, the incentive structure frameworks of incentive elements, incentive operation, incentive efficiency and incentive environment were constructed by using the whole and part research idea. Based on principle of dynamic feedback analysis, Vensiem PLE was used to respectively analysis the four subsystem causality diagrams, the dynamic feedback relationship among the influencing factors in each incentive subsystem were clarified. The results demonstrate that incentive goal consistency, inspire all links, incentive system integrity and market maturity are the key factors affecting the incentive effect of the whole system. Finally, some optimization suggestions on incentive mechanism are put forward to promote the buildings energy conservation reconstruction market development.

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.
