4.5.4  Windows

As has been noted above (Section 4.2.1), the proportion of window surface area to floor area must be 10% at minimum. It is good to locate the window facing south, south-east or south-west so that adequate sunlight can be possible throughout the day. The presence of two windows is advisable for effective ventilation.
