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 roof. When sunlight strikes a building the building materials can reflect transmit or absorb the solar radiation. This concept is based on the principle that the sun s light streaming into your home s windows generates heat. A solar pv system offset and additional 22 bringing the net energy use to near zero. 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.

In addition the heat produced by the sun causes air movement that can be predictable in designed spaces. 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. The measured energy consumption was 70 less on the house with low energy use features. Passive solar cooled house in tropical areas.

Let s start with passive solar roof design. 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. Light colored homes reflect the sun s light reducing the amount of heat retained in the walls and therefore lowering summer cooling loads. 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.

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. These basic responses to solar heat lead to design. 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.
