5. Common circulation areas are day lit and naturally ventilated through integration of skylights
and ventilators.
6. Selection of water cooled chiller that complies with the effi ciency recommended by the Energy
Conservation Building Code.
7. Variable Frequency Drive installed in the Air Handling Units (AHUs).
8. Low energy strategies such as replacement of water cooler by water body to cool the condenser
water loop, integration of thermal energy storage and earth air tunnels enabled reduction in
chiller capacity.
9. Integration of energy effi cient lighting design that complies to the recommendations of ECBC.
10. Integration of daylight with artifi cial lighting.
11. Optimized architectural design and integration of energy effi cient fi xtures has resulted in the
reduction in annual energy consumption by 41% from GRIHA’s benchmark.
Energy: embodied and construction
GRIHA encourages replacement of high energy intensive materials with low energy intensive
materials, to utilize regionally available materials, materials which use low energy in their
manufacturing process. Following are the measures incorporated at CESE building, IIT, Kanpur:
1. Portland Pozzolona Cement (PPC) with fl y-ash content is used in plaster and masonry mortar.
2. Wood for doors is procured from commercially managed forests. Modular furniture made from
particle board is used for interiors.
Energy: renewable energy utilization
Following are the measures incorporated at CESE building, IIT, Kanpur to integrate renewable
sources of energy with the building:
1. Renewable energy from photovoltaic panels provide annual energy requirements equivalent
to 30% of internal lighting connected load.
2. Hot water demand is met by solar hot water system.
5. Common circulation areas are day lit and naturally ventilated through integration of skylights
and ventilators.
