The most recognized systems include:

i) IGBC (Indian Green Building Council)

ii) GRIHA (Green Rating for Integrated Habitat Assessment)

iii) LEED (adapted by the U.S Green Building Council)

India faces increasing pressure on natural resources, rising pollution levels, and high energy demand. Green buildings help :

1. Lower electricity and water consumption

2. Improve thermal comfort

3. Reduce carbon footprint

4. Promote sustainable urban growth

Not necessarily. The incremental cost is usually 2–7% higher, and the payback time is typically 2–5 years
through savings on energy and water bills.

Yes. Retrofitting through measures like energy-efficient systems, rainwater harvesting, low-flow fixtures, and
waste management can earn certification for existing structures.

Everyone involved:

i) Occupants: Better indoor air quality and comfort

ii) Owners/Developers: Higher asset value and lower operating cost

iii) Government: Reduced strain on infrastructure

iv) Environment: Lower emissions and resource use

Yes. There is a unique rating program by IGBC called as IGBC NEST Plus Rating which certifies Individual Homes upto 150 sq.m (3230 sq.ft)

Yes. Various State Governments in India offers incentives like additional FAR/FSI, Property tax rebate, stamp duty exemption, reimbursement of
certification fee & infrastructure setup cost,Fast-track environmental clearances, Subsidies for solar, rainwater harvesting, and waste management, etc.

Not mandatory. Renewable energy is one of the credit areas, but a building can achieve certification through other measures like
energy-efficient lighting, rainwater harvesting, building orientation, high-performance glazing, and HVAC systems.

They integrate sustainability in:

i) Site planning

ii) HVAC and electrical design

iii) Water efficiency

iv) Materials selection

v) Waste reduction strategies

Many Indian architects and consultants like Auger Engineers are IGBC-AP, GRIHA-CP and LEED AP certified.

Many government bodies have made it compulsory or recommended:

i) CPWD mandates at least 3-star GRIHA for public buildings

ii) MoHUA encourages IGBC/GRIHA ratings in Smart Cities and AMRUT projects
