 Ventilation
Doors and windows should be positioned to achieve cross ventilation in summer.
A larger opening on the leeward side of the home will maximise the airflow
through rooms. If this has been allowed for in the design of your home,
doors and windows opened late on a summer's day will make use of cooling
late afternoon and night time breezes to rid your home of heat accumulated
during the day.
Draught proofing
Air leaks and draughts can add significantly to your heating and cooling
bills by allowing cold air into your home during winter and warm air
during summer. You can prevent these unwanted leaks by installing
draught excluders on the bottom edge of doors and sealing strips around
doors and windows. These are easy to fit and can be purchased from
your local hardware store. When draught proofing you should also check
for spaces between walls and skirtings and block off any unused fireplaces.
Note that homes with heaters that burn a fuel inside are required
by law to have fixed ventilation for safety reasons.
