The appropriate ventilation options for your home will depend on the climate and microclimate of the area you live in, and what prevailing breezes there are. As a rule of thumb, the area of windows, doors and other vents that can be opened up to the outside should be at least 5% of the floor area for each living space - and more for high-use areas.

Some points to consider:

• Windows or other openings on opposite sides of your home will help draw air through.
• Opening windows on the south and east side are best for allowing cool breeze into your home from early in the day. Openings on the north and west sides, higher up, will keep the air moving.
• Vents or other openings in the roof or on upper floors will allow air to escape as heat rises.
• Built-in vents, louvres, slots and gaps in door or window framing can provide low-level ventilation over long periods without creating draughts or security risks.
• Different types of window can be used to guide air into your home - for example, side opening windows are better at catching breezes and pulling them into the house, than awning opening windows
• If your home is on more than one level, make sure there are opening windows and doors on each level. As hot air rises, high windows which can be left open on upper floors can be a good way of ventilating your house during summer.
• Fly screens and security stays installed on windows mean they can be left open at night, or when you’re out during the day, to help the house keep cool in summer
• Don’t forget to ensure cross-ventilation under your floor to get rid of dampness (seeMoisture for more information)
