Existing landscape and vegetation are largely protected
and preserved. Sustainable site planning to resources
and minimize disruption of natural ecosystem.
Integrating the water body with design for optimal
microclimate.
Architectural design optimized as per climate and sun
path analysis, achieving reduction in energy consumption.
Optimization of building envelope by use of insulated
cavity walls, insulation of roof, and surface finishing
that reflects a major part of solar heat.
Efficient glazing for openings which minimize solar
grains in summer, heat loss in winter, and maximize natural
daylight.
Roof shaded by bamboo trellis with green cover to cut
direct heat gain.
Provision of an internal court shaded by louvers that
allow free air movement.
Natural light and ventilation through skylights &
ventilators in common spaces.
Use of indigenous and recycled materials with low embodied
energy.
It is estimated that after optimizing building envelope,
thermal comfort conditions would be achieved for more
than 90% of the occupied hours in the non air-conditioned
spaces.
Passive strategies such as Earth Air Tunnel and thermal
storage provided to enable reduction in energy consumption
for conditioning the building.
Efficient HVAC system with controls adopted.
Reduction in water demand by selection of efficient
fixtures.
Dedicated sewage treatment plant provided and the grey
water used for horticulture.
Rain water from the building and surrounding area collected
and routed through a sedimentation tank to water body
for AC cooling. Overflow is led to a groundwater recharge
pit.
Efficient lighting design with controls and integrated
day lighting.
30% of internal lighting demand met from renewable energy
source through photovoltaic panels.
Outdoor lighting demand met by solar energy.
Hot water requirement is met by solar system.
The facility is fully ECBC (Energy Conservation Building
Code) compliant.
The payback period is calculated to be approximately
5 years. An estimated net savings of 15% of total cost
in 15 years.
