Energy Efficiency Design And Practice Of Window In The Region Of Chengdu

Energy efficiency came on to the world because of the oil crisis in 1973. People began to attach importance to improving the efficiency of energy with the result of rise in price of energy.Energy efficiency is a very important symbol as for the advancement of architecture technique, and it is a key tache for our architecture field to carry out the sustainable development. We need to research the energy efficiency to improve the development of the society economy, to lighten the pollution of air, to change the thermal environment, and to develop the architecture.Some research organization made cut and try and put forward many theories on energy efficiency these years, and many techniques were applied into practice. In our country, the importance of energy efficiency was not known since 1980's, and we have got some achievement these years. Now, energy efficiency is considered not enough in architecture design although our energy consumption is more than other country. The energy efficiency in our country is the incipient stage and we have some distance compared with the developed country.The residence in Chengdu gets a rapid development there years, and the energy efficiency of the residence is the main part in whole energy efficiency. The heat consumption of residence composed by heat transfer though exterior-protected construction and air permeates though the gap of doors and windows. The heat consumption though window occupy 50%, so window is the important part in energy efficiency and change the performance of the window and enhance the obturation of window are the main contents in energy efficiency.The paper researched the elements of influence on window performance and the methods of energy efficiency, and the author gave some methods of design from investigation of residence in Chengdu. In addition, the author designed some widows of energy efficiency and validated them in lab. The author wishes that this research can give some clear and all-sided cognition to people and offer some theory basis for the design of energy efficiency on residence in Chengdu.
