ICMIEE-PI-14035410 000 Energy simulation to estimate building energy consumption using EnergyPlus

To achieve sustainable and green design, performance simulations are often used to verify these criteria and modify the design. The conventional approach of manual trial-and-error is too time-consuming to be practical. The evaluation of building energy consumption usually requires building energy profiles on month and category basis. EnergyPlus-Windows32-8.1.0.009, simulations were integrated to obtain this information but generating simulations requires a significant amount of experience, time, and effort to enter detailed building parameters. This paper presents a simple methodology to estimate source and site energy, where maximum energy requirement are 1485.14 MJ/m 2 and 447.6 MJ/m 2 ; respectively for D (mass type wall with attic) category within different categories (A-F) building. Moreover utility use per total floor area also calculated. Maximum U -factor with or without film are 0.512, 0.554 W/m 2 .K; respectively for wall of building. For one year max tariff charge is 63.5$ on electrical source energy consumption for D category building. In addition to summer and winter clothes maximum and minimum uncomfortable time are 436.25 (for D-category and 390.75 (for E-category) hours as annual. The methodology has been applied to hypothetical buildings placed in Jessore, Bangladesh.
