日本《太阳》1986,Vol.12,No.2对日本近铁技术研究所的节能建筑进行了简单的报导。该建筑物是利用夜间降温时的外界空气,通过换气来降低室温的。为了确定其节能效果,实测了建筑物的热特性,进行了模拟试验,对比了实验值,并且研讨了其经济性。其结论如下:1、模拟值和实验值吻合。2、内部绝热的建筑物,墙壁和地板为太阳能的蓄热体,故只是换气时,壁温下降要适可而止, Japan’s “Sun” 1986, Vol.12, No.2 gave a brief report on the energy-saving buildings of the Kintetsu Institute of Technology in Japan. The building uses the outside air at night to cool down, and the room temperature is reduced by ventilation. In order to determine its energy-saving effect, the thermal properties of the building were measured, simulation tests were conducted, experimental values ​​were compared, and the economics were studied. The conclusions are as follows: 1. The simulated value agrees with the experimental value. 2. The interior of the building is insulated, and the walls and the floor are solar regenerators. Therefore, when the air is changed, the wall temperature must be reduced.
