Energy efficiency analysis of attached sunspace heating house and saving hot-wall heating house

Aiming at rural typical courtyards structure and traditional usage way of cooker in Qingdao, the transformation of attached sunspace and saving hot-wall was carried out. The related thermal parameter of transformation house and the contrast house was monitored; the results show that the average air temperature in attached sunspace solar house and saving hot-wall heating house was higher than in the contrast house by 4.3°C and 3.8 °C . Through ESF analysis computation for heating energy-saving rate, it was found that the energy-saving rate of transformation house is high.
