Let s start with passive solar roof design.
Passive solar roof.
It typically is constructed of containers holding 6 to 12 in 150 to 300 mm of water on a flat roof.
Passive solar design refers to the use of the sun s energy for the heating and cooling of living spaces by exposure to the sun.
A well designed passive solar home first reduces heating and cooling loads through energy efficiency strategies and then meets those reduced loads in whole or part with solar energy.
Therefore you want to allow the sun s light to shine on windows or even exterior walls only when it is cold outside and you want to block the sun s rays when it is hot outside.
In addition the heat produced by the sun causes air movement that can be predictable in designed spaces.
A roof pond passive solar system sometimes called a solar roof uses water stored on the roof to temper hot and cold internal temperatures usually in desert environments.
A solar pv system offset and additional 22 bringing the net energy use to near zero.
The reports provide quite a bit of detail on the saving achieved by each energy efficient design feature.
Passive solar design takes advantage of a building s site climate and materials to minimize energy use.
Passive solar homes can be any color just like normal homes but they lose a major advantage if they aren t painted to suit the climate.
Passive solar cooled house in tropical areas.
These basic responses to solar heat lead to design.
Because of the small heating loads of modern homes it is very important to avoid oversizing south facing.
The measured energy consumption was 70 less on the house with low energy use features.
Light colored homes reflect the sun s light reducing the amount of heat retained in the walls and therefore lowering summer cooling loads.
