Criteria for GRIHA rating 91
Criterion 27 Minimize ozone depleting substances
Objective
Eliminate or control the release of ozone-depleting substances into the atmosphere. The ozone
depleting materials commonly used in buildings are CFCs or HCFCs in refrigeration and air-
conditioning systems, halons in fi re suppression systems and extinguishers, and in insulation.
27.1 Commitment
27.1.1 Use insulation with zero-ODP (ozone depletion potential) such as HCFC-free rigid foam
insulation, mineral fi bre cellulose insulation, glass fi bre, wood fi bre board, cork wool,
expanded (bead) polystyrene, recycled newspaper, and jute and cotton. Avoid materials that
do not inherently have a zero-ODP, such as polyurethane foams and polyisocyanurates.
27.1.2 Install CFC-free equipment for refrigeration and air conditioning.
27.1.3 Install halon-free fi re suppression systems and fi re extinguishers in the building.
27.2 Compliance
Following documents are to be submitted.
27.2.1 A certifi cate from the manufacturer/supplier, signed by the architect or the engineer, stating
that 100% of the insulation used in the building is free of CFCs and HCFCs.
27.2.2 The bill of quantity clearly demonstrating that 100% or total quantity of all the insulation
used in the building is free of CFCs and HCFCs.
27.2.3 A certifi cate from the HVAC consultant or supplier, signed by the architect or the engineer,
stating that the HVAC and refrigeration equipments/systems installed in the building are
free of CFCs.
27.2.4 A list showing each type of HVAC and refrigeration equipments/systems, their numbers and
type of refrigerant used along with the manufacturers’ brochures clearly stating the type of
refrigerant being used in their products.
27.2.5 A certifi cate from the fi re-fi ghting-service consultant or the equipment supplier, signed by
the architect or the engineer, stating that the fi re suppression systems and fi re extinguishers
installed in the building are free of halon.
27.3 Appraisal (maximum point – 1) mandatory
27.3.1 All the insulation used in building are CFCs and HCFCs free, as per clauses 27.2.1 and
27.2.2. and
27.3.2 All the HVAC and refrigeration equipment are CFCs free, as per clauses 27.2.3 and 27.2.4.
and
27.3.3 The fi re suppression systems and fi re extinguishers installed in the building are free of halon
as per clause 27.2.5 (1 point).
