CASE STUDY

Great Ashton Academy, Smoke & Natural Ventilation Systems

The Great Ashton Academy, formerly known as New Charter, is located in Ashton-under-Lyne, Greater Manchester. Designed by Faulkner Browns Architects, it provides a small school environment with state-of-the-art facilities and first class learning resources. The facilities are for the local community and other nearby schools as well as the students.

The building itself is designed to create a healthier environment in which to learn by incorporating an energy efficient, natural ventilation system in all classrooms with combined smoke extract in communal areas.

Working closely with Inspired Spaces, Emcor and Glassolutions, Dyer Environmental Controls provided controlled automation to windows, roof vents and double glazed louvres to provide day to day natural ventilation. These vents will also provide smoke extraction in the event of fire.

By working closely with Glassolutions, Dyer was able to value engineer the design and offer cost effective alternative solutions including roof vents and additional louvres, certified to EN12101-2, to achieve the required free areas.

Working with the BMS specialist Emcor, Dyer provided seamless operation between the Building Management System and Dyer’s automated window solutions. Dyer’s GVL and RZN control panels take a 0-10v signal from the BMS and integrated fire alarm system to operate the windows and vents, ensuring an effective and efficient ventilation strategy that complements the building’s other functions.
Dyer RZN smoke control panels also provide 72 hour battery back-up so should there be a mains failure the smoke ventilation system will still be operational.

CDC 200/350 chain drives are installed on the windows, 226 drives in total. ZA 85/800 BSY+ Set rack and pinion drives are installed on the roof vents. Due to the size of the roof vents, x2 ZA drives were installed on each opening, with a total of 28 drives used. The ZA drives are programmed with BSY+ technology which allows the synchronous operation of these drives to maintain the integrity of the vent as it opens and closes. Specialist louvre drives are installed on the glazed louvres. The drives, in both natural and smoke ventilation systems are controlled by a total of 10 RZN 431E6 and 15 GVL 8408-M panels.

Dyer Environmental Controls’ expertise in whole building ventilation solutions has enabled this academy to provide the safe, healthy learning environment that they had hoped for.
