o Solar energy is being additional wide used as a

property building technique. It’s going to be
utilized in two strategies in Sustainable building,
one for active solar energy and passive solar
energy.

o Active solar energy makes use of star panels that

absorb the sun's light weight and convert it into
heat and electricity. Passive solar energy, on the
opposite hand, makes use of the sun's rays to heat
dwellings by rigorously putting windows and
endoergic materials.

o The windows permit energy to flow in, and

therefore the heat absorbed minimizes the
necessity for electricity to heat the house
throughout colder months.
