About 75% of the buildings expected to exist in India in 2030 have not been built. In this context, India offers a huge opportunity to avoid carbon lock-in associated with new buildings. To encourage and improve the new building stock’s energy performance in India, we have created, in partnership with the Shakti Sustainable Energy Foundation, a dedicated programme of activities, adapted to India’s economic and demographic context.
By 2050, India will have seen an unprecedented floor area escalation of almost 400%. This growth combined with improving levels of comfort is expected to have a very dramatic impact on energy consumption.
To maximize energy savings, it will be essential to focus on constructing new energy efficient buildings. The largest growth is expected to occur in the residential building floor space between now and 2050, but energy efficiency in new residential buildings is still to be regulated.
To contain the energy use and enhance CO2 savings of all new buildings in India, it is fundamental to develop ambitious building energy efficiency regulations and policy packages aiming at limiting the energy consumption for new buildings.
We see a huge potential for energy savings and CO2 mitigation in the Indian building sector, and a massive lock-in risk. At current rates of code adoption, building energy demand in India will increase by five times that of 2005 levels by 2050 representing a lock-in of about 1.2 Gt of CO2 emissions. If no actions are taken the residential building stock will increase its energy use by around 800% and CO2 emissions by 840% compared to the baseline year of 2005. Currently there is very little coverage of the residential sector by India’s ECBC.

Deep Renovation or Deep Energy Renovation is a term for a building renovation that captures the full economic energy efficiency potential of improvements. This typically includes a focus on the building shell of existing buildings in order to achieve very high-energy performance. The renovated building consumes 75% less primary energy compared to the status of the existing building before the renovation. The energy consumption after renovation for heating, cooling, ventilation, hot water and lighting, is less than 60 kWh/m2/yr. (Definition often used in Europe) [Source: GBPN, 2012]
The calculated or measured amount of energy needed to meet the energy demand associated with a typical use of the buildings, which includes inter alia, energy used for heating, cooling, ventilation, hot water and lighting (EU). [Source: EPBD recast, 2010/31/EU]
NZEB are buildings that over a year are neutral, meaning that they deliver as much energy to the supply grids as they use from the grids. Seen in these terms they do not need any fossil fuel for heating, cooling, lighting or other energy uses although they sometimes draw energy from the grid. [Source: IEA (Laustsen J.)
