Project details

Located on Bishopsgate in the heart of Spitalfields, the Folgate Building is a multi-tenant office development undergoing a major refurbishment and extension led by CLI Dartriver, crafted to provide market-leading environmental performance and outstanding design quality in harmony with the context of its surroundings.

Integrated AET Systems Across All Floors

As part of the transformation, AET’s underfloor air conditioning system was installed across floors 1 to 7, with three CAM—V units serving each level.
Following the CAT—A shell and core works, a new tenant has chosen the 2nd, 3rd, and 4th floors for their latest UK headquarters, triggering a CAT—B fit-out tailored to their interior design and layout requirements.

Tailored Airflow Across Three Floors

Across all three floors, a total of 179 TU4 Fantiles™ were commissioned, combining existing CAT—A units with new CAT—B configurations — 64 on the 2nd floor, 61 on the 3rd, and 54 on the 4th. In addition, 39 Flextouch units were installed to give occupants individual control over their comfort.

This setup demonstrates the adaptability of AET’s UfAC system, supporting high-performance environmental control, flexible workspace layouts, and evolving tenant requirements.

Slim Void, Full Performance

On the newly added 7th floor, where the floor void height was limited to 200mm, we installed slimline Fantile™ units to maximise ceiling height without compromising performance.

Across the remaining floors, a consistent 300mm floor void was maintained, ensuring optimal airflow, system efficiency, and futureproofed service flexibility throughout the building.
