"E-concave",which is one of the entries in the Solar Decathlon 2013,has the core concepts of"Saving",Comfort","Unitization"and"Technology"and brings passive strategies( layout,insulation,daylighting,ventilation,material,etc.) into the design. This article aims to explore the utilization of passive design in solar detached houses through the studies on E-concave and tries to be an example to the development of sustainable buildings in China.展开更多

One is the crawlspace warm air heating system and the other is the crawlspace hot water circulation system. Based on the field study result, by using the simulation sol, ware, THERB, the effectiveness of the crawlspace warm air heating system has been examined. The effect of the factors, such as the wind amount circulating between crawlspace and indoor space, foundation insulation condition, and heat amount into the crawlspace, on the indoor thermal environment has been analyzed. Based on these analyses, the measured crawlspace heating system can make the average temperature of the living room above 20℃. These two houses have excellent thermal environment. According to the simulating result, heat amount input into crawlspace, which can make comfortable indoor thermal environment, for every month in heating period has been roughly concluded, and they are 600 W in December and March and 800 W in February and January, respectively.展开更多
