Energy Efficient Architecture
The idea of Energy Efficient design is
to modulate the conditions such that they
are always within or as close as possible to
comfort zone.
Modulations introduced by the
landscape,built form,envelope,materials and
other control measures bring the conditions
within the range throughout twenty four hours
cycle.
This is goal of Energy Efficient Architecture

Biogas Plant at Trombay.
The plant produces biogas from kitchen waste by using
thermophilic microorganisms that flourish in extreme environment

Actual Design considerations
with respect to site
1.Green spaces are designed in
heirarchy. Central common green
space,Space at the centre of
clustres,courtyards at the centre of units.
2.Each unit designed around a
courtyard.
3. Shopping area segregated to avoid
crowding.
4. Minimal road area to avoid traffic.

5.Orientation of the units as per climatic
conditions.
Units segregated to benefit from sun and
wind.
6.Privacy provided to each unit by
positioning them accordingly
7. Renewable and waste Management
services applied to site.

Services incorporated
. Waste water collection
•
and reuse by recycling.
• Solar photovoltaic
panels used for
electricity generation.
• A common biogas plant
for whole of the site.
• Solar water heaters for
hot water.
• Solar panels for street
lighting

4. Court yard provided for each house giving enough privacy ,to be
used as cozy sit outs.
5.Natural look given to buildings by using exposed bricks and

6. Enough vegetation provided where the surfaces are exposed to
direct sunlight.

CONCLUSION
The process of Architectural Design is a
complex exercise involving interactive
relationships between Parameters of
diverse nature and varying magnitudes.
A logical process based on quantitative
assessment leading to qualitative
decisions that respond to economical and
ecological context will result in
satisfactory environment comfortable to
the human beings,
A SUSTAINABLE HABITAT
