Solar Heating And Cooling Of Buildings

A well designed passive solar home first reduces heating and cooling loads through energy efficiency strategies and then meets those reduced loads in whole or part with solar energy.

Solar heating and cooling of buildings. Passive solar heating strategies provide opportunities for daylighting and views to the outside through well positioned windows. Therefore a nearly zero energy building incorporating a solar heating and cooling system was designed and built in beijing china. The key to designing a passive solar building is. To give a full picture of solar active systems applied in buildings solar cooling technologies are also discussed.

Passive solar design takes advantage of a building s site climate and materials to minimize energy use. The building sector accounts for more than 40 of the global energy consumption. It is underlined that sorption cooling technologies may help in solving a problem of working fluid overheating in the collector loop and in storage encountered in solar combisystems i e space heating plus hot water heating. Because of the small heating loads of modern homes it is very important to avoid oversizing south facing.

The whole building approach evaluates it in the context of building envelope design particularly for windows daylighting and heating and cooling systems. The application of building codes to solar energy systems for heating and cooling of buildings is discussed using as typical codes the three model building codes most widely adopted by states and localities. In passive solar building design windows walls and floors are made to collect store reflect and distribute solar energy in the form of heat in the winter and reject solar heat in the summer.
