Abstract

This article focuses on Nearly Zero Energy Consumption Residential Building, Using software such as Green Building SWIER, a model was established, and the simulation results under different operating conditions were compared and analyzed. The results show that when Increasing the thickness of the insulation layer generally reduces energy consumption by improving thermal performance. Vacuum insulation panels (VIPs) reduce energy consumption for external wall insulation from 44.6 kWh/m2 to 43.14 kWh/m2 when the thickness increases from 20mm to 30mm. Similarly, rock wool boards show a reduction from 55.8 kWh/m2 to 53.58 kWh/m2 at the same thickness increase. VIPs are more energy-efficient at the same thickness compared to rock wool boards. Additionally, for VIPs, internal insulation consumes slightly less energy (42.11 kWh/m2) than external insulation (43.14 kWh/m2) at 30mm thickness. For rock wool, internal insulation is also more efficient than external insulation at both 20mm and 30mm thicknesses.
