Indoor thermal environment of kindergarten building: A case study in China

Based on the building of a kindergarten in Weinan, Shaanxi Province, this paper explores influence different envelope structures and heating modes indoor thermal environment for energy saving comfort existing buildings. Using operating temperature as evaluation index comfort, 15 designed schemes were simulated through Energyplus software actual measurement to obtain change law annual consumption value. The structure optimized by choosing energy-saving materials such expansion perlite foam cement is obviously conducive improvement thickness insulation layer increases, increases accordingly; Although standard effective intermittent mode slightly lower than that continuous mode, rises significantly with extension preheating time, which can meet requirements comfort.After transformation, total reduced up 3644 GJ, rate reaches 67%.
