تحقیق در مورد صرفه جویی در انرژی - صرفه جویی در صرفه جویی در پشت بام خانه های سنتی

With the rapid development of social economy and people’s living standards continue to improve, summer air-conditioning energy consumption has gradually become the focus of modern society energy consumption. At the same time, the traditional residences are an important part of the ancient Chinese architecture culture and heritage, which contain rich experience in ecological construction, but limited to the economic level and construction technology at that time, and the traditional residences have their flaws. As one of the largest energy consumption of the envelope, the roof is the need for renovation. In this paper, energy-saving renovation of the demonstration building on the town of Chongqing was taken as an example. It puts forward the practice of using the controllable ceiling and uses DesignBuilder software to compare the energy consumption before and after the transformation and the indoor temperature in summer. The results show that the building energy efficiency rate is 54.35%, and the cumulative percentage of the length of the temperature of bedroom1 over 30 ℃, while over 28 ℃ is reduced by 7%. The cumulative percentage of the intermediate bedroom temperature over 30 ℃ is reduced by 16 %, and over 28 ℃ by 12%. By taking the control of the ceiling to reduce the cumulative time of the indoor high temperature, which can be delayed air conditioning opening time by the next day, to achieve energy-saving effect.
