Single-sided ventilation
The Illustrated Guide to Mechanical Building Services, Third Edition (BG 31/2017), by David Bleicher, published by BSRIA in 2017, suggests that: ‘Single-sided ventilation describes a space primarily ventilated by wind entering one or more openings within a single external wall. On days when there is little or no wind, limited ventilation is still possible if windows have top and bottom openings. This will enable convection currents in the space to expel warm air through the top opening and draw fresh air in at the bottom (stack ventilation). Large vertical openings are also effective, such as horizontal sliding sash windows.’
