The stunning building constructed in the early 1900’s was once the UK headquarters for the Bank of Montreal, and since 1991 has accommodated a branch of Lloyds bank. AET Flexible Space are delighted to have supplied a CAM-C direct expansion underfloor air conditioning system for this prestigious refurbishment; comprising 8 CAM-C 35 downflow units, Daikin heat pumps and approximately 108 TU4-EC Fantiles.
The underfloor system was specified by consultant Watkins Payne Partnership for four floors within the seven floor building. Both the client, Cornerstone Real Estate and Architect, Morrow and Lorraine, had requested a clean finish with no services at high level to allow the decorative feature plasterwork in the ceiling to be left exposed. The AET Flexible Space CAM-C direct expansion system fits this brief perfectly.
The CAM-C downflow unit supplies conditioned air into the plenum beneath the raised access floor, which serves as the ventilation zone. This zone is divided into supply and return air paths using airtight relocatable baffle and then the CAM receives spent air back at floor level for re-conditioning, allowing the total elimination of services located in the ceiling. Conditioned air is fed into the space using modular, plug and play TU4 Fantile units with the upgraded EC fan option for additional energy efficiency.
Completed in April 2017, the refurbishment was successful in creating fully refurbished, additional net area grade-A office space, an enlarged reception and alterations to the top storey to create a roof terrace. The building was also shortlisted for the 2017 BREEAM awards, refurbishment category and Chinese restaurant giant Imperial Treasure has secured 8500 sq. ft. of mezzanine, ground and basement floors on a 25 year lease deal.
