Abstract

The aim of this study is to perform the thermal analysis of an existing building by a software, hence determine the possible improvements and energy savings. In this context, the existing model and two different improved models of a building are compared. The 1st case covers the existing situation of the building while the 2nd and 3rd cases are related to two improved cases for the building. The improvements are focused on heat insulation, infiltration and lighting system of the building. The results point out that 2nd and 3rd cases provide a reduction in electricity consumption by 15% compared to the 1st case. Similarly, annual natural gas consumption is decreased about by 76% and 90% in 2nd and 3rd cases, respectively in comparison with the 1st case. The total energy consumption by electricity and natural gas per unit area for 1st, 2nd and 3rd cases is also determined as 55.7, 35.7 and 33.1 kWh/m², respectively. Moreover, annual CO₂ emission is ensured to reduce nearly by 23% in both 2nd and 3rd cases compared to 1st situation.

评估和改进建筑物的能效：案例研究

本研究的目的是通过软件对现有建筑进行热分析，从而确定可能的改进措施和节能效果。在此背景下，我们对建筑物的现有模型和两种不同的改进模型进行了比较。第 1 个案例涉及建筑物的现有情况，而第 2 和第 3 个案例则涉及建筑物的两个改进案例。改进的重点是建筑物的隔热、渗透和照明系统。结果表明，与第一种情况相比，第二和第三种情况的耗电量减少了 15%。同样，与第一种情况相比，第二种和第三种情况的天然气年消耗量分别减少了 76% 和 90%。第 1、第 2 和第 3 个案例单位面积的电力和天然气总能耗分别为 55.7、35.7 和 33.1 千瓦时/平方米。此外，与第一种情况相比，第二种和第三种情况的二氧化碳年排放量确保减少近 23%。
