Introduction of Eco-Niwas Samhita 2018 Why Eco-Niwas Samhita has been created?  Built Up Area - India will add 3 Billion m² by 2030 of New residential building w.r.t Year 2018  Energy Demand - There is a 4 times increase in energy demand for residential units from 1996 – 2016  Projections show energy demand will be approximately between 630 TWh and 940 TWh by 2032 Source: Eco-Niwas Samhita 2018 4 Bureau of Energy Efficiency, Ministry of Power, Government of India

Introduction of Eco-Niwas Samhita 2018 What is Eco-Niwas Samhita 2018? ECO-Niwas Samhita 2018 - an Energy Conservation Building Code for Residential Buildings. Launched on National Energy Conservation Day in 2018. Applicable to all residential units with plot area ≥ 500m 2 (However, states and municipal bodies may reduce the plot area so that maximum residential buildings fall in the category of ENS compliance ) 5 Bureau of Energy Efficiency, Ministry of Power, Government of India

Other Existing Government initiatives Energy Conservation Building Code (ECBC) • The ECBC sets minimum energy performance standards for commercial buildings. ECBC defines norms of Energy performance for various • building components and takes into consideration the climatic region. Eco-Niwas Samhita 2018 Energy Conservation Building Code for Residential Buildings • 6 Bureau of Energy Efficiency, Ministry of Power, Government of India

Other Existing Government initiatives BEE star rating programme for Office buildings. BEE has developed a star rating programme for buildings which is • based on the actual performance of a building in terms of its specific energy usage in kwh / m² / year. This programme rates commercial office buildings on the scale of 1 - 5 star, with 5 Star labelled buildings being the most efficient. BEE star rating programme for electrical appliance. The star rating is a measure of energy efficiency of an appliance, it is • a five points scale where higher the rating, lower is the energy consumed by appliance. 7 Bureau of Energy Efficiency, Ministry of Power, Government of India
