Passive Solar Roof

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.

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. It typically is constructed of containers holding 6 to 12 in 150 to 300 mm of water on a flat roof. In passive solar homes effective weatherproofing and insulation and thus near airtightness is a necessity if primary reliance upon sunlight for climate control is to be possible. 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. 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. This concept is based on the principle that the sun s light streaming into your home s windows generates heat. When sunlight strikes a building the building materials can reflect transmit or absorb the solar radiation.

In simple terms a passive solar home collects heat as the sun shines through south facing windows and retains it in materials that store heat known as thermal mass.
