Pp Sustainable Buildings

Sustainable buildings Ideas that we can use to make out houses more energy efficient and sustainable.

Solar cells

Makes electricity from sunlight Unfortunately they are expensive, low power and not very efficient

Wind turbine Turned by the kinetic energy of the wind

Coils of wire cut through a magnetic field making electricity

Solar panels

The Sun heats water circulating through the panel A tank of water can be heated for showers, washing, heating, etc.

HEAT EXCHANGER

Fresh cold air

Stale cold air

Incoming cold air is heated by outgoing hot air

Stale hot air

Fresh hot air

Geothermal Heat pumps A liquid is pumped through a long, underground pipe It takes heat out of the ground into the house

Thermal mass

During the day the house gets hotter

A house with a large thermal mass keeps warm longer

During the night it releases heat
