If the statistics provided by Indian Green Building Council is an indication ‘Net Zero Buildings’ are making some headway in India. According to IGBC’s Annual Review report, till now, more than 10 corporates have committed to make their buildings Net Zero Energy in near future. About 1,55,984-sq.m of built-up area of different types of buildings including corporate offices, IT/ITES buildings, factory buildings and warehouse are in the process of implementing Net Zero Energy concept and 6 projects have already achieved the status of Net Zero Energy Buildings, says IGBC’s Annual Review report.
Net Zero Building is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site, or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels. The goal is that these buildings contribute less overall greenhouse gas to the atmosphere during operations than similar non-ZNE buildings.
Some of the net zero building initiatives in India so far are:
- Plant-13 Godrej & Boyce, Mumbai
- Globicon Terminals, Mumbai
- ICICI RSET Jodhpur
- Capgemini, EPIP campus, Bangalore
- CII-Sohrabji Godrej Green Business Centre, Hyderabad
- Sheru Gems, Surat
- HZL, Udaipur
- HURC, Bangalore
- Bhawar Homes, Chennai
- Capgemini Hyderabad
IGBC’s own headquarter in Hyderabad is Net Zero Energy Platinum rated. In another interesting development, Godrej &Boyce Manufacturing Company, a Godrej Group company has joined the World Green Building Council’s Asia Pacific Regional Network as a Corporate Activity Partner to advance the dialogue in accelerating uptake of net zero carbon buildings in the Asia Pacific region.
According to IGBC, Net Zero rating has facilitated installation of total 2010 kWp rooftop solar PV system which generates 2919 MWh annually. Wheeling of Off-site Renewable energy has offered opportunities to reduce significant operational energy cost. Further, Net Zero Energy certified projects are wheeling green power equivalent to 11,905 MWh, annually.
