การพัฒนาวิธีการประเมินค่าการถ่ายเทความร้อนรวมและการใช้พลังงานรวมของอาคารชุดพักอาศัยในกรุงเทพมหานคร / ดนุสรณ์ บัวขจร = Development of an assessment method for overall thermal transfer value compliance and whole building compliance of condominiums in Bangkok / Danusorn Boakajorn
This research proposes a method for estimating the Overall Thermal Transfer Value (OTTV) and the whole building energy consumption of condominium buildings under the Energy Conservation Act of Thailand B.E.2550 by creating a reference condominium building that complies with the typical design of condominiums and occupancy to determine the base level energy use of a condominium. The VisualDOE4.0 simulation tool was used in this research, which started with acquiring two types of data. One is a set of condominium shapes in Bangkok and nearby provinces. Another is a set of occupancy profiles. The data were gathered and analyzed in the VisualDOE4.0 program and the parameterization method was used to create the coefficients in the OTTV and the whole building energy (Ec) equations. The resulting equations suggest that the base level energy use be 126.22 kWh/m2-year and the OTTV of the reference condominium in this research, called “OTTVcondo”, be 26.5 W/m2. The average coefficients of the “OTTVcondo” that comprise TDeq, ΔT and ESR are 5.43, 0.97 and 91.40 respectively. However, energy use results from the proposed equation and computer simulation show discrepancies of -5.9% to 7.2%, which result from the average TDeq, ΔT and ESR applied in the study. It is recommended that a further, detailed study regarding the effect of building orientation be carried out.
