The prestigious development by Helical, known as Kaleidoscope, will be a six storey office building of 88,60sqft with a restaurant unit on the ground floor. The floor-plates range from 14,000 sq ft to 19,500 sq ft and the building benefits from a communal rooftop terrace of 5,000sqft together with 94 cycle spaces, showers and its own loading bay. It is situated immediately east of Smithfield Market with views over Charterhouse Square and towards St Paul’s Cathedral. As well as anticipating a BREEAM 'Excellent' rating after a pre-assessment exercise, the prestigious building (designed by PLP Architecture) displays outstanding aesthetic endeavour and has achieved a WiredScore Platinum rating, meaning it is at the at the forefront of digital connectivity. Development of the scheme started in August 2018 and completion is due in December 2019.

Trox PWX fan-coils were the natural choice for the Kaleidoscope development, to assist the achievement of ambitious sustainability goals, and to provide optimum flexibility for layout of the office spaces. Launched in 2017, the PWX fan-coil was the result of an extensive research and development programme and was put through thorough testing, using Trox’s in-house test chamber (constructed to comply with ASHRAE 79, BS1397 and EUROVENT 6/3), in addition to extensive corroboration of results at an independent test facility.

Trox PWX units feature new inlet attenuators, inlet plenums and discharge attenuators capable of achieving outstanding performance across a wide range of applications. SFPs across the range comply with and exceed Part L requirements, with typical values between 0.15 to 0.25 W/(l/s) at 30 Pa ESP.

The Trox PWX range is able to speed up the specification of projects significantly, streamline installation and commissioning, and provide valuable environmental and cost benefits whilst reducing levels of risk. This has resulted in the PWX being selected not only for the Kaleidoscope development at the Farringdon East Crossrail Station, but also for many other notable projects around the UK.
