| Abstract |
This study aims to assess the impact of envelope design factors on the total energy consumption of cooling, heating, and lighting sector in
office buildings and to suggest priorities among energy-saving design alternatives. The approach involved selecting a baseline model and
various variable levels for the office building, followed by energy analysis simulations using the design of the experiment method. Sensitivity
analysis, based on energy consumption data obtained from these simulations, calculated the contribution rate and influence of each design
factor. Additionally, a design-stage alternative flow chart was presented, and a predictive energy consumption equation was developed through
multiple regression analysis for additional analysis. The study presents a method enabling designers to compare diverse alternatives based on
envelope design factors in the early design stage and choose the energy-efficient optimal design alternative. |
