Passive solar building technology aims at the maximum
collection/ absorption of natural solar heat energy followed by storage and
distribution without any use of the conventional energy. This technology can be
finally used in heating or cooling with the help of some additional devices of
the particular building/area.
It is hence vey important for regions of cold climate where
energy for space heating is a major daily item of domestic energy requirement.
Passive solar heating of building has been already successfully carried out in
ladder of India and Peru in South America.
Solar heating can be used for space heating in order to
provide adequate warmth inside house, lodge, restaurants, and other facilities
in the hills and mountain. The solar space heating system can be an avtive
system which requires conventional energy to operate it. Similarly it is a
passive system which operates entirely on the renewable energy available in the
immediate environment.
The passive heating or building through solar energy involves
the integration of the system into the structure of the building itself. The
system works I three ways.
1.
Collection of sun rays
2. Storage
of the heat collected and
3.
Release of the heat in a useful way
The technique that can comes under solar passive heating are
1.
Direct gain
2. Indirect
gain
3. Isolated
gain and
4.
Solarium
Maintenance costs for solar heating systems are generally very low. Most solar heating systems come with a five-year or ten-year warranty and require little maintenance. Once fitted your installer should leave written details of any maintenance checks that you can carry out from time to time, ensuring everything is working properly.
