  • Don’t break the bank to solve your corridor overheating problem Many residential buildings, by becoming very well insulated for energy efficiency, have developed a vexing problem: unpleasantly hot corridors and stairs. However, in the vast majority of cases, the solution is simple and inexpensive: use the smoke control equipment to provide day-to-day ventilation to these areas. Building with two-shaft smoke control system: zero cost You can easily configure a two-shaft system to provide inlet and extract air for cross flow ventilation. The shafts are typically positioned in a way that provides effective ventilation for both smoke evacuation and environmental ventilation. No more hot and stale air in your building’s common areas! Building with single shaft control system: small additions are enough In this case, you need a source of inlet air: this can be provided by a weathered roof smoke vent for the stair plus fire rated smoke dampers between stair and corridor. For best results, a control system and balancing dampers will prevent uneven ventilation: if all dampers open fully on all floors, most of the ventilation comes from the higher floors, while the lower floors will suffer from insufficient ventilation. You can further improve the result by modulating the fans to prevent the heat from building up in the first place. So, depending on the severity of your problem, you can easily resolve it without breaking the bank. Webinar If you want to know more about preventing overheating in your building with a dual purpose shaft system, you can attend our forthcoming webinar on this topic.
