Passive Solar Overview


Passive solar design was first clearly understood by the Greek and Roman architects. Facing very high costs for imported charcoal they developed innovative building designs that utilized the sun for heating and microclimate resources for cooling. The importance of the sun led to the development of the first solar cities and solar rights. Passive solar design was also included in many other traditional buildings systems, from China to India, the tropics to northern climes. But these lessons were forgotten in the dark Ages and more recently, the fossil fool age.


The energy crises of 1973 and 1979 triggered Federal and private investment in solar design, including passive solar systems. Up to this point the elements of passive solar architecture had emerged as orientation, south facing windows, solar control to limit overheating in summer, and ventilation. Using these alone it was possible to reduce building energy use dramatically but more could be done if this was seen as a systems problem where cooling was equally important.


Passive solar design strategies can improve the comfort and performance of buildings in any climate. In many areas these buildings can be built a cost equal to conventional buildings. Passive solar design can provide comfort and security from the low deserts of Arizona and California to the icy winters of Alaska. These buildings save money for owners and improve security, and also reduce peak power demand. The energy and financial savings over the lifetime of these naturally heated and cooled buildings can help improve the outlook for California and for the world by reducing greenhouse gas emissions and providing security in an ever more vulnerable world.
