The design should manage breezes and allow for controlled ventilation while reducing uncontrolled air leakage. Ventilation is important for thermal comfort, air quality and moisture control.
Managing breezes involves:
- using operable windows;
- having windows on both sides of the dwelling for cross-ventilation;
- landscaping and window layout to capture cooling breezes in summer;
- landscaping and window layout to deflect cold breezes in winter; and
- having high-level windows to allow hot air to escape and draw in cooler air from low-level windows.
Controlling ventilation involves:
- using operable windows that seal well;
- locating windows so they can be open and secure regardless of the weather;
- installing weatherstripping and draught-sealing doors;
- sealing the dwelling to minimise uncontrolled air leakage.
