This is a building design
approach that focuses on
heat gain control and
heat dissipation in a
building in order to
improve the indoor
thermal comfort with low
or nil energy
consumption.
Insulation is added to
buildings for comfort and
energy efficiency. It
helps in maintaining the
indoor temperature by
keeping cool/warm air out
and keep cool/warm air in
as needed by the
proprietor.
