The evaluation and improvement for the energy performance of buildings: A case study
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.
