How To Heat Your Home Using Only The Sun
Passive solar is a building design approach that incorporates certain materials into the roof, walls and floors that collect solar energy to heat a home in the winter, cool it in the summer, and heat water year-round. It’s called passive because it requires no electric devices or mechanical devices to operate and performs various functions.
This is not about collecting solar energy through dedicated solar panels to generate electricity. It’s about temperature management. In its simplest form it involves the use of windows with a southern exposure that simply allow the sunlight to enter the home in winter, and are shaded with blinds or window shades in the summer. Many people take advantage of that sunlight by installing special, thermal tiles in their floors to absorb the heat during the day, and release it slowly during the night. There are also wall panels that perform the same function. Certain types of floor tiles and wall boards collect the heat.
You have to be able to shade windows in summer. Otherwise, you can get something referred to as passive/aggressive solar heating. The result is a house that is too hot during the day, especially in summer. You want that “Goldilocks”
