An underfloor air conditioning system has allowed architects to highlight key architectural features in a central London refurbishment project.
The 77 Coleman Street development, designed by Buckley Gray Yeoman architects on behalf of Kajima Properties, offers office space overlooking Coleman Street Gardens and is close to the new Elizabeth Line station at Moorgate.
The system from AET Flexible Space makes use of the void within the building’s raised-access floor, and so removes the need for traditional ceiling-based services and suspended ceilings. By using the existing 270mm floor void, the design team were able to preserve and highlight key architectural design features, including a unique terrazzo-patterned soffit.
Moving away from conventional ceiling-based services has allowed 77 Coleman Street to boast unusually high floor to ceiling heights, creating a brighter and more open office environment. When used in refurbishments, underfloor air conditioning technology can typically offer increased headroom by 300mm or more.
AET worked with both the M&E consultant, The GDM Partnership, and architects Buckley Gray Yeoman for over three years on the application and specification of their underfloor air conditioning before receiving the order from the appointed M&E contractor, Designer Group.
The development is now in the final stages of completion and the CAM-V system has been installed across all seven floors of office space. Each floor is served by four CAM units, and the conditioned air is delivered into the space via 48 floor-recessed Fantile units, eliminating cold draughts and providing the end user with complete control over temperature and air flow.
