ANNOUNCEMENTS
Energy consumption in the building sector contributes to around 40% of the world’s total energy consumption. Designing energy efficient buildings aims to reduce the energy consumption of the building while keeping care of occupant health and comfort. Various rating systems have been developed to rate the buildings on a given set of parameters reflecting their effect on the environment. One of the building rating system is GRIHA which has been developed in India. The work in this study involved working under criteria 8 of GRIHA rating system for buildings which is related to energy efficiency. The project involves performing energy simulation of a hypothetical residential building using e-QUEST and calculating the yearly energy consumption and the Energy Performance Index. The project calculates the proposed EPI of the building and compares it with the GRIHA baseline EPI. Using energy efficient design and systems savings of 46.6% from the GRIHA baseline EPI was achieved. This made the project eligible for 7 points out of 10 under criteria 8.1.5. A cost analysis was also done by replacing the proposed Double Glazed Unit glass with efficient glass. It resulted in 0.5% more yearly savings. The extra capital cost required for the new glazing was calculated and the discounted payback period was found to be 15 years.
