Systems will vary depending on building layout.
Where a building is so tall that there’s a risk of smoke-logging, rendering a natural system ineffective, a mechanical system can be considered.
If your building has extended corridors, you’ll need a mechanical system.
Mechanical systems can perform with much smaller shaft sizes, typically between 0.6m2 and 0.8m2.
If you want to learn more about mechanical systems, including where they’re applicable, how to specify them, what products to use, what legislation governs them, we’ve got a comprehensive CPD to help you out.
