Cross Ventilation

So how does it work?

Windows and doorways can be designed to let you control cross ventilation for natural cooling.  It’s important to position them so that breezes can flush excess internal summer heat build up. Assess your plan and work out the best window placement to take advantage of cooling summer breezes. Ensure that breeze pathways work to naturally cool your home in summer. There are ways to effectively use courtyards and planting to trap and redirect breezes.

If there are high windows available, these will allow warm air to escape, especially if cool air can be introduced from another window.

Take Action

Existing houses

Choose windows and doors which give airflow across the whole of a room/space and install insect or security screens which allow them to be opened at the end of hot Summer days.

Building/renovating

Position windows and doors so that they take best advantage of prevailing breezes and give airflow across the whole of a room/space.  Install insect or security screens which allow them to be opened at the end of hot Summer days.
