Powered Smoke Shaft Ventilation System for Ditton Walk, Cambridge

20 December 2009

News article image for Powered Smoke Shaft Ventilation System for Ditton Walk, Cambridge
Project: Ditton Walk.

Location: Cambridge.

Title: Providing a smoke ventilation solution within a residential premise to provide safe escape routes for occupants in the event of a fire and to provide clear access for the fire service to enter the affected area, using powered ventilation techniques.

Challenge: To design, install and commission a smoke ventilation system for the three storey block of nineteen apartments at Ditton Walk, Cambridge.

Benefits: The fire engineered solution specified has minimised the impact of the Smoke Heat and Exhaust Ventilation system (SHEVs) on the usable floor space, creating an economic benefit to the client, through a reduced sized smoke shaft using powered extract rather than natural smoke ventilation.

The maximum travel distances allowable under Approved Document B was increased by incorporating a fire engineered solution. Additionally the powered smoke shafts have effective extract rates considerably higher than a natural system resulting in clearer more tenable means of escape and fire fighting conditions.
