components (shadowgap linear slot diffusers, frameless chassis swirl diffusers) minimised any impact on the overall aesthetic.
Thinking outside the box
Grade II* Grantley Hall is a case in point. The five-star hotel’s new swimming pool’s ventilation need was met with a conventional solution- a return air grille- in an unconventional location- concealed behind a perforated screen embossed with the venue’s logo. The new £3.5million boathouse for one of
Oxford’s colleges was in a conservation area. Standard penthouse terminals on the roof provide ventilation stacks for most of the venue; one has been discreetly engineered to serve as a duct for the MVHR required for the shower rooms and cope with
Advances in modern design, construction methods, materials and testing mean it is easier than before to solve the problems.
the additional moisture generated therein. The auditorium at the Royal Albert Hall features
conventional swirl floor diffusers, design- engineered with bespoke components including an intumescent fire block and damper, installed under the seating. This enabled rapid mixing and entrainment into the seating area right where the audience needed it, displacing the existing, warmer, stale/used air upward to be extracted at high level.
Sometimes the answer is simpler: Virgin’s first hotel in the UK involved the integration of not one, but three, listed buildings into one cohesive entity. Standard double deflection and linear bar grilles have been fitted throughout. Specialist powder coating, vinyl finishing and hydro dipping enables the diffusers to almost disappear into the existing fabric- even the wood panelled walls.
Summary
As in any redevelopment or refurbishment project, the key is to work with people and companies you trust. To work with those who have the experience, expertise and willingness to be brave enough to rise to a challenge and help transition our historic buildings for the benefit of present and future generations.
