Passive solar heating and cooling systems are great; they make use of basic physics in that they are meant to use sunshine and warm, rising air as well as cool air as it falls to either heat or cool a building. And, in fact a solar heating and cooling system can do all this without having to use fans and water pumps or other active mechanical equipment. This means that a passive solar heating and cooling system is going to be very cheap and easy to install and use.
Passive solar heating and cooling systems can be used in hot and humid climates when in the nighttime the air is too warm and is filled with water vapor which makes direct ventilation impossible. It is indeed a huge challenge to create the perfect solar heating and cooling system though with companies such as Zero Energy Design™ Inc. around many of the challenges have been solved and very cost effectively as well.
At night, it can get very warm when temperatures can rise to above eighty degrees Fahrenheit and there will also be too much water vapor (in excess of fifty percent relative humidity) which is when direct building ventilation will not be feasible. This is when you will need to turn to a solar heating and cooling system that will provide the necessary solutions to cool the air and also remove the water vapor from the air.
The fact of the matter is that there are very few companies and individuals that understand how to use state-of-the art design as well as implementation of a good solar heating and cooling system. At the same time it must also be mentioned that the Greeks, about two thousand five hundred years ago, understood what today is known as a solar heating and cooling system. Of course, the latest solar heating and cooling systems are (some of them at least) truly state-of-the art that are not even known to the ordinary user but which nevertheless can provide very effective solutions.
There are other companies that have done a lot in improving solar heating system design. One company that stands out in this regard is Radiantec that from the time of its inception in the year 1979 has been actively engaged in improving the way that solar heating systems function. They have a few proven and time tested solar heating systems that are based on the results of years of rigorous research and study. And, this is a company that too has won a number of awards that stand testimony to their dedication to providing the best solutions for those looking to make use of solar energy.
