LEED GRIHA BEE Star rating
I Introduction It is meant for rating new and
existing Commercial,
institutional and high-rise
Residential building.
All buildings, except for
industrial complexes and
housing colonies, which are in
the design stage, are eligible for
certification under the TERI
system.
Buildings include offices, retail
spaces, institutional buildings,
hotels, hospital buildings,
healthcare facilities, residences,
and multi-family high-rise
buildings
existing buildings which
are minimum one year old
after construction/
Buildings include office
buildings, BPO as of now.
Hospitals and hotels in
process
