SOLAR ENERGY SYSTEM IN BUILDINGS
There are two types of systems which employ the solar energy systems
1) Passive solar energy systems.
It uses the building in combination with solar energy as an energy-saving system. In order to reduce the fuel energy consumption, A passive building uses its various properties like site features, structure, environment and the material used. Day light gives light to inside of building is called passive lighting
What is a Heating systems?
The Solar thermal system has three parts.
1 Collector system,
2 Storage system,
3 Distribution System.
The building is collector in a passive solar heating system.
Sun’s rays through windows heat the room or space in direct sunlight in direct systems. The extra heat is stored for later use in the walls and floor of building.
Popular passive heating systems are greenhouse and sunspaces.
Cooling systems. When the passive heating system is reversed , passive solar cooling occurs at night. The building radiate heat to the sky. The building walls cool down, and the building cools down inside. These Cool building wall keep the building cool without any air conditioning.
Natural ventilation, is another form of passive cooling. If walls have ventilators near the ceiling. As heated air rises to the ceiling and exit through the top openings, cooler air will enter through the lower openings.
If a building is shaded during the summer, natural cooling also occurs.

first Solar Energy Park
Garden of five senses is home to the Delhi’s first Solar Energy Park set up with the assistance the Ministry of Non Conventional Energy Sources. A large pavilion holds solar powered cars, computer & bicycles, solar bus and a solar home creating awareness regarding the renewable energy sources. The Solar Energy Park is listed in the 2004, Limca Book of Records.
