Cost Analysis of Greening an Existing Building

Abstract

We can use rooftop solar system and solar wind hybrid systems in existing building both can easily balance the requirement of fossil fuel-based energy thus reducing carbon footprint. The sector is becoming one of the highest contributors to the country’s carbon emission. Its alone accounts for 22% of India’s total carbon emissions so we can use green building concept in India to reduce carbon emissions. An estimated by the “Indian green building council at present there are only 2204 certified green building in India but is it is projected to rise to about one lakh by 2025. So, if we similarly make existing buildings into green building it helps us to improve in the number of certified green buildings.
