Abstract
Before Eco-Niwas Samhita (ENS) 2018, India lacked a formal code for building energy performance, leading to outdated regulations on floor space. The Eco-Niwas Samhita (ENS) 2018 allows architects to create low-energy buildings by breaking down spaces into three categories: openable window to floor area ratio, visual light transmittance and overall heat loss/gain coefficient. The purpose of this study is to assess the code’s success in enhancing buildings’ thermal performance which reduces energy use and boosts occupant comfort. The evaluation is carried out in accordance with energy assessment rules, with an emphasis on classifying energy performance efficiency. Employing ENS as well as the universal energy performance index (UEPI), the study attempts to assess the energy efficiency of separately planned homes in Indian cities. These evaluations are carried out to establish the normalized yearly electrical energy consumption per unit of building space. Two case studies of residential buildings in Indore, Madhya Pradesh, meet the ENS code for 2018, but window shading and top slab insulation need scientific attention. This research makes an effort to close the gap between the two. A residential building complex in Indore City is examined for conformity with the Eco Niwas Samhita through the aid of this study. This research contributes to sustainable building practices and emphasizes the importance of adopting energy-efficient measures in construction projects. Policymakers, architects, engineers and developers can use this information to make informed decisions and support a sustainable and energy-neutral future. This analysis demonstrates how energy savings are feasible if the basic standards for energy efficiency are met by all typical buildings. It also emphasizes the potential savings that were otherwise lost since residential buildings were not subject to the same regulations. The findings of this investigation demonstrate the significance of encouraging sustainable practices in homes and provide evidence for the necessity of energy-saving measures. Retrofitting a building can contribute effectively and efficiently to the energy efficiency of the building.
