Gilberts (Blackpool) - ‘Revolutionary Concept’ Delivers Beneficial Lifetime Solution

BAM Construction - Natural Ventilation - EFA Guidance - Air Distribution

Gilberts MFS in Situ

BAM Construction is utilising a revolutionary concept to simplify delivery of effective ventilation.

With a series of new-build and refurbishments in the education sector, the company has chosen Gilberts’ Mistrale Fusion System (MFS) as a ‘one-stop shop’ solution for the ventilation strategies.

Explained BAM Construction senior project services engineer Gavin Wilcox, “Natural ventilation is the preferred option under EFA guidance. Our design team proposed Gilberts’ MFS as a commercially viable alternative to other schemes, providing intake and extract in one ‘stand-alone’ box. The flexibility to match the MFS units to a particular project’s specific properties was a further determining factor. The MFS concept means fewer units, so reduced installation, reduced interfacing, reduced maintenance- all beneficial to the lifecycle costs of the building.”

Gilberts’ MFS was the first primarily natural ventilation solution to evolve into a dynamic hybrid, by minimising heat loss via a low power fan and mixing damper rather than the conventional heat exchanger. It has continued its innovation, being the only such system that can be easily tailored to the specific project requirements. Its modular design enables airflow, temperature, CO2, pollutants to be precisely matched to specification, whether integrated into the building via façade, window or roof. Further, Gilberts’ in-house design, R&D and engineering capability means, if required, bespoke solutions can be detailed for the core system.

Thus, at the Elliott Hudson College in Leeds, BAM has used 2no standard MFS128 and 21no. high capacity MFS256 units with heating coils, integrated into the classroom windows, with Gilberts’ window-mounted up/down louvre on the external facade. To ensure an airtight fit, Gilberts specially engineered a duct extension/ transition piece to accommodate the building’s existing façade which is angled 6° from the vertical. In addition, 10no MFS-V roof-mounted units with heat coils, six for the main hall, and two each for the fitness studio and drama studio respectively have been installed.

The standard MFS is supplied as a 128 variant: just two of these single-sided units will achieve the appropriate Building Bulletin ventilation requirements of 8l/sec/person for a standard 32 person classroom, allowing for one unit to be positioned at each end of the room. The MFS256 was developed as a high capacity solution, to provide the Regulatory ventilation requirement where only one unit could be integrated into the façade. Gilberts’ MFS-V is a vertical version, for roof-mounting.

Specification of a heat coil is an option, which, Gilberts maintains, can potentially eliminate the need for supplementary heating, radiators, within the room. Further options include a 550 boost, for rooms subjected to greater potential pollution, heat gain (eg science laboratories), and filter boxes for locations with heavy outside air pollution.

“There’s nothing else like it on the market,” says Gilberts’ Technical Director Roy Jones. “BAM Construction is just one of many companies appreciating how the concept delivers a commercially viable, sustainable alternative to the conventional means of ventilating a building.”

Founded 50+ years ago, privately owned Gilberts is unique in having its own, on-site (85,000ft²) manufacturing facility, producing engineered solutions, with an in-house test centre. Technical expertise is supported by full in-house testing, and CFD (computational fluid dynamics) simulation capability.
