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.

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. This is called passive solar design because unlike active solar heating systems it does not involve the use of mechanical and electrical devices. This consumption may be lowered by reducing building energy requirements and using renewable energy in building energy supply systems. The whole building approach evaluates it in the context of building envelope design particularly for windows daylighting and heating and cooling systems.

Passive solar heating strategies provide opportunities for daylighting and views to the outside through well positioned windows. 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. Passive solar design takes advantage of a building s site climate and materials to minimize energy use. To give a full picture of solar active systems applied in buildings solar cooling technologies are also discussed.

The building sector accounts for more than 40 of the global energy consumption. The key to designing a passive solar building is. Window design and especially glazing choices is a.
