Passive solar energy for homes makes the best use
of the sun, the wind, the construction material
and the site to ensure a house is as comfortable
as possible inside all year round. Passive solar
energy residential design Employ these 7 basic
fundamentals about passive solar energy for homes
and start saving money and energy today! 1.
Orientation, layout and positioning of your house
on the land Orientate your living areas to the
south side of the house, which receives most of
the sun throughout the day (north if you live in
the southern hemisphere). 2. Insulation and
draught proofing Make sure your walls, roof and
floors are insulated and fill any gaps where
draughts might come through. 3.
Ventilation Position doors and windows opposite
each other to allow for a cooling breeze to flow
through the house when the air cools down in the
evening of a hot summers day. 4. Windows Windows
on the south side of the house should be bigger
to allow more sun to penetrate the house during
the day and windows on the north side smaller to
prevent heat lost at night. 5.
Landscaping Position trees and plants to direct a
cooling breeze into your house, whiles shading it
during summer. Plant trees that shed their leaves
in winter. 6. Shading Make sure external shading
structures are wide enough to block out the sun
in summer, while still allowing the low winter
sun to enter. 7. Thermal mass Polished concrete,
tile or slate floors and brick walls will absorb
the heat throughout the day and release it slowly
at night, reducing the need to run expensive
heaters. Carpet acts as an insulator and will not
retain the heat.
