Project Description

CASE STUDY
Southway & Charter, Eccles, Smoke Ventilation

Buildings

Dyer Environmental Controls were delighted to be installing life-saving smoke ventilation systems as part of the impressive regeneration of 12 high-rise blocks in Eccles, Manchester.

Dyer provided systems for 5 blocks at Barton Village, 5 blocks at Ladywell Green and a further 2 blocks at Southway and Charter. The high rise improvement programme by City West Housing Trust is working with customers to deliver a cost effective, energy efficient solution for the future.

System

Smoke Ventilation is a vital consideration in a high rise development as it is the smoke that inhibits escape and rescue.

After successfully combining the first phases, Dyer was able to assist in the value engineering of Southway and Charter. Through Dyer’s input, a new smoke vent louvre system has now been installed, to enable a more efficient ventilation system to be introduced. This EN-Certified smoke louvre system provides a more effective smoke ventilation solution whilst also meeting the demands for a successful natural ventilation solution, especially at high level.

Dyer Environmental Controls provided a bespoke louvre design which not only was able to provide the smoke ventilation area required for Approved Document B for Fire Safety, but was also able to meet the demands required under Approved Document K for Protection from Falling.

Products

A total of 64 double glazed louvre vents tested in accordance with EN 12101-2, were installed to provide dual-purpose natural and smoke ventilation. Additional stainless steel crossbars were introduced into the louvre design, ensuring safety from falling from height.

The louvres are operated by D+H LDF 24V DC drives which provide proven anti-trap technology in case of obstruction when the louvre blades are closing. The specially-developed LDF has an unobtrusive, compact stainless steel housing and controls the force and position for the synchronous operation of louvre windows.

These multiple safety features, combined with the ventilation provision, were able to provide a highly secure solution which simply wasn’t achievable through the use of normal window designs.

To complete the solution, the automated louvres were connected to the EN12101-10 certified RZN4503-T smoke ventilation control panels.
