Build with the climateWhy?
15/02/2019 BIOCLIMATIC DESIGN
The main objective in construction of a
physical facility is to provide a place for
humans (bio) in order to achieve
their goals.

When climate affects
the building as an
environment built with
a particular physical
form at a particular
location.

If the building design
process ignores the
climate
considerations, the
influence of climate
can lead to
interference with
human activities.

Bioclimatic design is
a concept of
sustainable approach
that consider of
climate and
human relations in
reviewing the
feasibility of a design.
