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.

Roof ponds as passive heating and cooling systems by traceitlab. The main aims were to gain a detailed understanding of different roof pond configurations. This paper systematically reviews literature on passive heating and cooling of buildings using roof ponds. Since the invention of roof pond system by harold hay and his colleagues in late 1960s 18 19 a vast body of work has been.

What is roof pond roof pond is a passive cooling technique based upon the increased heat capacity of cheap and widely available water. 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. Roof ponds are a way to passively cool and heat your house during summer and winter. 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 brief history of the development of the roof pond concept is presented and several existing roof pond buildings located throughout the united states are. H2o sun 3. Passive solar applications when included in initial building design adds little or nothing to the cost of a building yet. Roof pond passive cooling.

17 roof ponds are capable of providing passive heating and cool ing. 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. 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. To demonstrate a roof pond system that uses water and sun to heat and cool without electricity.

Passive solar heating presents the most cost effective means of providing heat to buildings. In general the pond is covered during day to prevent heating and open at night.
