In IGBC GH energy-enhanced performance is based on a percentage of energy cost savings and in GRIHA, it is based on a reduction from the benchmark energy performance index (EPI).<br>Results: The maximum percentage of energy cost savings in IGBC GH was found to be in the range of 37.05–42.96%, whereas the maximum reduction from benchmark EPI in GRIHA varied in the range of 28.16–44.10% under different climate zones.<br>Conclusion: Although this study’s combinations allowed for the maximum energy efficiency points in IGBC GH, it was not possible to achieve full points in GRIHA.</p> Rakesh P B B Das Copyright (c) 2024 Journal of Advanced Research in Civil and Environmental Engineering 2024-09-25 2024-09-25 11 2 5 11 https://adrjournalshouse.com/index.php/civil-environment-engineering/article/view/2101 <p>Introduction: The use of energy-efficient building envelope materials, as well as the installation of high-efficiency HVAC systems, has been shown to be particularly beneficial in lowering building energy consumption. The adoption of energy efficiency measures in residential structures is fairly restricted in India. The purpose of this study is to investigate how the material type of building envelope components, HVAC efficiency, and heating temperature set point affect the life cycle of a residential structure in India’s cold climate.<br>Method: In this study, resin-bonded mineral wool (RBMW), expanded polystyrene (EPS), and polyisocyanurate (PIR) roof insulation with thicknesses of 50 mm and 100 mm were used. The wall envelope was made of clay brick (base case) and autoclave aerated concrete blocks (AAC). The coefficient of performance of HVAC has been varied from 3 to 5 and the heating set point temperature from 22 °C to 19 °C.<br>Results: The energy savings of the combined measures were found to be 40.85%, the life cycle cost (LCC) savings were up to 24.88% and life cycle energy (LCE) savings were up to 33.57%.<br>Conclusion: The use of energy efficiency measures was found to be very cost-effective and resulted in a significant reduction in energy use during the life cycle of the building.</p> Rakesh P B B Das Copyright (c) 2024 Journal of Advanced Research in Civil and Environmental Engineering 2024-09-25 2024-09-25 11 2 1 4
