Roof Pond Passive Solar System

This paper systematically reviews literature on passive heating and cooling of buildings using roof ponds.

Roof pond passive solar system.

The roof uses water either plastic bags filled with water or an open pond as the heat sink while a system of movable insulation panels regulate the mode of heating or cooling. What is roof pond roof pond is a passive cooling technique based upon the increased heat capacity of cheap and widely available water. An indirect gain solar passive design that provides both heating and cooling is the thermal pond approach which uses water encased in ultraviolet ray inhibiting plastic beds underlined with a dark color that are placed on a roof. 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.

However by reviewing the sizing techniques for the other systems and by knowing the specific design of the roof pond system an approximate ratio can be calculated. Experimental roof pond building. 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.

H2o sun 3. It has proved more effective than these systems. During daytime in the summer the water on the roof is protected from the solar radiation and ambient air temperature by movable insulation which allows it to serve as. For the do it yourselfer seeking an inexpensive easy to build solar water heating system the integral passive solar water heater ipswh pronounced ips wah is a dream come true.

Even on cloudy days passive solar heating designs continue to collect energy from diffused sunlight. To demonstrate a roof pond system that uses water and sun to heat and cool without electricity. 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. Of the roof pond heating variants skytherm is the only one that has been compared with other common passive heating systems such as direct gain trombe wall and sunspace.

Hence this system is known as roof pond solar passive heating cooling system. Research on comparing roof pond systems with other passive techniques is also limited. Roof pond passive cooling.
