Roof Pond Passive Solar Heating

It typically is constructed of containers holding 6 to 12 in 150 to 300 mm of water on a flat roof.

Roof pond passive solar heating.

Passive solar applications when included in initial building design adds little or nothing to the cost of a building yet. Generally the amount of solar energy that falls on the roof of a house is more than the total energy consumed within the house. 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. This paper systematically reviews literature on passive heating and cooling of buildings using roof ponds.

The main aims were to gain a detailed understanding of different roof pond configurations and their performance compare effectiveness of different roof pond variants evaluate performance of different roof pond variants relative to other passive design techniques explore effects of. Roof ponds as passive heating and cooling systems by traceitlab. What is roof pond roof pond is a passive cooling technique based upon the increased heat capacity of cheap and widely available water. A brief history of the development of the roof pond concept is presented and several existing roof pond buildings located throughout the united states are.

17 roof ponds are capable of providing passive heating and cool ing. Experimental roof pond building. H2o sun 3. An introduction to the roof pond passive solar space heating and cooling concept is provided including basic methods of operation and system configurations adaptable to different climates.

To demonstrate a roof pond system that uses water and sun to heat and cool without electricity. In general the pond is covered during day to prevent heating and open at night. The vapors were discharged from the pond in order to improve the building s summer performance whereas the same will reduce the efficiency of the system in winters. Passive solar heating presents the most cost effective means of providing heat to buildings.

Roof ponds are a way to passively cool and heat your house during summer and winter. Roof pond passive cooling.
