Analysis on the Effect of External-Wall Insulation on Energy Consumption of Residential Building in Lanzhou
Based on the comparison of external wall with different insulation thicknesses and without insulation, residential buildings energy consumption was simulated by using hourly energy consumption simulation software DeST-h in Lanzhou.The effects of external wall insulation on building energy consumption were analyzed. The result shows that the total annual load can be reduced to 42% ~ 72% with the insulation thicknesses vary from 10mm to 80mm. But With the increase of the thickness of the insulation layer, the amount of fluctuation of building load reduce gradually.That is not to say the insulation layer is thicker the energy saving effect is more distinct and there is shoud be the thickness is the most economical thickness. So the economic insulation thickness is determined as 40mm by using a life-cycle cost analysis.
