The key elements of the concept are.

Exposure of the water pond to sunshine for heating.
Roof ponds with wet gunny bags shaded roof ponds ventilated roof ponds and roof ponds with movable insulation proved to be more effective relative to other variants of roof pond cooling systems.
They introduce moisture to building structures such as roof ponds or water sprayed onto evaporative pads and incorporate stacks or chimneys that use convection to exhaust rising hot air and draw cooler low level air into the building.
To prevent the liner from getting lifted by the wind i simply placed old tires on top of the roof.
A simple and free solution suggested by a neighbor.
Numerical study of thermal behavior in roof pond under the hot and humid climate simulation program comsol multiphysics by miss sasicha sakdawattananon.
The pond liner has been an inexpensive and effective diy solution that i would surely recommend for flat buildings.
Tips and lessons from our field editors.
Filling my 6 000 gallon pond would have run my well dry and the local pool service wanted 400 to fill it.
What is roof pond roof pond is a passive cooling technique based upon the increased heat capacity of cheap and widely available water.
Thermal coupling of the water with the occupied spaces.
Cool breezes work best in narrow or open plan layouts.
A solar pond is simply a pool of saltwater which collects and stores solar thermal energy.
The saltwater naturally forms a vertical salinity gradient also known as a halocline in which low salinity water floats on top of high salinity water.

Do the same for the pump s power cord so you can remove or replace the pump without moving stones.
