Passive Solar Roof

Passive solar design takes advantage of a building s site climate and materials to minimize energy use.

Passive solar roof.

Passive solar cooled house in tropical areas. This concept is based on the principle that the sun s light streaming into your home s windows generates heat. Because of the small heating loads of modern homes it is very important to avoid oversizing south facing. The reports provide quite a bit of detail on the saving achieved by each energy efficient design feature.

The measured energy consumption was 70 less on the house with low energy use features. 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. When sunlight strikes a building the building materials can reflect transmit or absorb the solar radiation. Let s start with passive solar roof design.

A solar pv system offset and additional 22 bringing the net energy use to near zero. These basic responses to solar heat lead to design. Passive solar design begins with the simple idea that you can build a house that uses natural heating cooling ventilation and daylighting these homes require much less fossil fuel energy to heat. It typically is constructed of containers holding 6 to 12 in 150 to 300 mm of water on a flat roof.

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. 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. 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.
