Net Zero Energy concepts and techniques encourage to use of Renewable Energy sources to meet the energy requirements of the building. It would result in
- Improvement in energy efficiency and hence reduction in annual energy consumption to the tune of about 25-30% with respect to the National baseline.
- Overall reduction in energy cost of at least about 30%.
- Reliable source of power supply if combined with energy storage devices.
The rating system evaluates buildings on a performance-based approach. The rating system is evolved to be comprehensive and at the same time user-friendly. The programme is fundamentally designed to reduce the energy needs of a building and national priorities.
IGBC Net Zero Energy Building rating system addresses energy efficiency and Renewable Energy through the following sections
- Energy performance
o Simulation approach
o Prescriptive approach
o Energy efficient building envelope
o Air conditioning
- Renewable Energy
- Thermal comfort, Indoor temperature and RH
The mandatory requirements and credits earned at the preliminary review are only considered as expected. These mandatory requirements and credits are not awarded until the final documents are submitted, along with additional documents showing implementation of design features.
IGBC Net Zero Energy Buildings Rating System is designed for both new and existing buildings/ projects, both for air-conditioned and non-air-conditioned spaces.
Net Zero Energy Building (NZEB) Rating is applicable to Commercial, Industrial as well as Residential building projects those are able to off-set 100% annual grid energy use by renewable energy sources (either on-site and or off-site). These buildings include but not limited to offices, banks, IT parks, shopping malls, hotels, hospitals, airports, convention centers, educational institutions (schools, colleges, university Campus), Factory Building/ projects, Warehouses, Railway Stations, etc.
The threshold criteria for certification levels are as under :
|Net Zero Energy
|Net Zero Energy Platinum
||80 and above
IGBC will recognise Net Zero Energy Buildings that achieve one of the rating levels with a formal letter of certification and a mountable plaque. Net Zero Energy certification can be awarded either at Design Stage or during Operation. A building which achieves Net Zero Energy Certification at Design State must showcase Net Zero Energy Performance after one year of building operation.
