I came to know regarding this competition from rediff.com
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
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

Energy Efficient Architecture-Sustainable Habitat

  1. 1. 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

  20. 20. 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.
  21. 21. 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.
  22. 22. 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
