Posted by Graeme Clark on 30/06/15 11:30

Ventilation is needed in atria for heat dissipation, to manage carbon dioxide and body odour levels, as well as for smoke clearance or smoke control. What better way to provide this than with a dual purpose day to day and smoke ventilation scheme?

In the third article in our series about designing smoke shaft systems, we look at the rooftop equipment.

Natural shafts
