Guidelines for Improving Building to Reduce Energy Consumption Case Study : Watabaek Subdistrict Administrative Organization Office, Thepsathit, Chaiyaphum

Abstract

Abstract

      This research presents a method for improving the Subdistrict Administrative Organization building to reduce energy consumption and assessment of energy use was assessed by using BEC V.1.0.6. The results indicated of buildings had OTTV, RTTV, and LPD which did not pass the minimum energy benchmark according to ministerial regulations. Thus, the researcher suggested 4 approaches. The presented approach was convenient, and it had minimum effects on the appearance of the building. After the building was renovated, the researcher suggested renewable energy like solar energy with the building by using PVWatts Calculator. The results indicated that It was an appropriate building for passing all groups of benchmarks, including renovation according to the fourth approach by improving lighting equipment, exterior surface materials, translucent wall material, and opaque roof material for having the ability of energy value reduction in overview as 10,873.87 kWh per year, calculated as 22.46%. Renovation expenses were 431,775 baht. In addition, when operating with 83 solar modules by using a budget of 509,205 baht. Therefore, it was the building that use zero energy. The project has a payback period of 6.14 years.
