LEED (Leadership in Energy and Environmental Design) is
the global standard and TERI-GRIHA (Green Rating for Integrated Habitat Assessment) is National standard for green-building certification.
In both cases, credits are given for every element thatreduces a building¶s ecological footprint.
Studies show 20% drop in life-cycle cost.
Buildings built on Energy andBuildings built on Energy and
environmental efficient standardsenvironmental efficient standards --
Site selection: Close to municipal infrastructure; not in fertile farm land; away from ecologically
critical spots
Design: Maximize use of natural contours, light, heat, wind and water; minimize built area
C onstruction: Prevent destruction of tree cover, top soil, and natural water channels; use low-
energy recycled material
P roducts, systems and processes:
that reduce energy (lighting and cooling)
that reduce, recycle and recharge water;

Innovative cooling solutionsInnovative cooling solutions-- GeothermalGeothermal
Geothermal system:
At a depth of 100-400 feet, temperatures remain
constant through the year depends on site and soil
condition.
Geothermal systems use this temperature differential
(surface vs. depth) for heating/cooling A coolant is pumped underground for heat exchange
This significantly reduces the overall tonnage of the
compressor and energy consumption
This will be coupled with a passive cooling system,
where an underground air tunnel will be used to cool-
down ambient air Energy consumption reduction upto 40%-65%
depending on location when combined with earth air
tunnel
Average Payback around 3 years

Innovative cooling solutionsInnovative cooling solutions--
Radiant cooling systems:
Is a surface cooling system where the water tubes
are placed in the roof slab absorbs the heat from heat
sources in a room. The Slab absorbs the heat and
exchanges it with the circulating water. The warm
water is then pumped to a chiller or a geothermalheat exchanger , re cooled and returned to the slab
.

chilled Beam systemschilled Beam systems
It is essentially a ceiling mounted induction unit with ventilation airpassed through the duct that is part of the chilled beam and inducesroom air up over the cooling coil mixes with the primary ventilationair and delivers it through the linear diffusers.
Chilled beams can other wise be called as Fan coil units with out fan
The unit removes only sensible load and hence uses dry cooling coil

RAIN WATER HARVESTING- INTEGRATED APPROACH
During monsoons, the earth absorbs up to 30%of rainfall. This can drop to as low as 0-5% forbuilt areas. One Acre of land receives over 3million liters of water in single monsoon seasondepending on rainfall in that area.
The remaining water runs off, and is lost
Rainwater harvesting captures runoff water tostore & reuse, or to recharge the water table.
Runoff water channeled using pipes into a basicfiltration system, and then into a large storagetank
This water could be used for non-potable
purposes Water overflows from the storage tank will be
used to recharge the water table using aquifers
Opportunities to become water positive andensuring water sustainability
