Made to measure

When a new central London development required cooling for several different environments, a bespoke solution was required for optimum performance

Trox UK is nearing the end of its latest £1m project in Central London, having been tasked to supply its air cooling products to the 1 & 2 New Ludgate project, which sits just a stone’s throw from the Old Bailey.

Working again with developer Land Securities, which has a number of recent London-based concepts, Trox UK delivered bespoke solutions to ensure the effective air cooling and energy efficiency at the multi-use 382,000 sq ft venue.

The building, which includes office space, restaurant accommodation and retail use, is due for completion in the coming weeks. It is the type of environment which can pose all sorts of challenges to the HVAC industry, particularly when maintaining optimum cooling for so many areas of use throughout day and night.

Nick Howard, key account manager from Trox UK, says: “This was a large-scale project for us, but very much of the type we are particularly good at because it emphasised our abilities to provide bespoke solutions based on considerable analysis and testing back at our Thetford headquarters.”

Specifically, the client had tasked that the HVAC system created maximum energy efficiency and employed the latest technology.

Mr Howard adds: “The client specified low specific fan power requirements and EC motors in the Fancoil units. The system was designed by the M&E consultant [Watermans] and Trox UK supplied the fancoil units and diffusers that best suited the requirements.

“Our first response to this request was based around using EC motors on our fancoil units. This approach promotes really good energy savings for the client in this particular environment.

“With the components and systems we provide, we’re very much able to create a bespoke answer for the building we’re in, and that style of working was what made for such a successful project in this case.

We also received free issued BMS controllers (fitted at the factory) along with RFI filter for harmonic filtering and EMC compliance. The controller and filter are not particularly geared towards energy efficiency, though.”

Designed by architects Fletcher Priest, the building required Trox UK’s specialist 4-slot diffusers both on the perimeter and internally. More than £500,000 worth of fan coil units were also fitted, with volume regulators.

Testing proved a significant part of the project timeframe, with Trox UK staging its own mock-up at its Thetford headquarters.

Mr Howard says: “This is something we often do to ensure we’ve taken good measure of how the complex nature of our client’s building will work with our product.

 “We designed and created a mock-up of an entire section of the building in our main UK facility, and carried out a thorough air distribution test.

“We also featured in our testing process a full assessment of our fancoil unit rig, to prove just how effective our thermal performance was going to be in the final environment.”

Smooth delivery

HVAC projects in mixed-use facilities can bring their own set of difficulties that have to be taken into account. However, steps were taken to ensure that ensure the project was delivered smoothly.

“It’s certainly the case that in some cases it can be more difficult when you’ve got an office environment to consider, restaurant accommodation and retail too,” says Mr Howard.

“However, Land Securities is very clear with us as to what it needs, and we are thorough from the outset about what is possible and how we can tailor our components for each of the respective areas of the main building.

“We’ve worked with this client for a long time now, so it’s useful to have a relationship where you can discuss the potential challenges from the very start – and work your way through them before the real work even begins.”

The project follows a number of significant city installations of late for Trox UK, including ones in London’s 20 Fenchurch Street, and at Glasgow’s SSE Hydro. A series of new commissions are to begin in the coming months.

A final handover of this mixed-use project is yet to take place, but it will involve a detailed and clear collaborative process to ensure the system is best optimised both now, and in the future, says Mr Howard.
