Three of the award-winning Carrier chillers were installed by NG Bailey to support the development's Building Research Establishment Environmental Assessment Method (BREEAM) rating of Excellent, and are used in combination with off-site Modern Methods of Construction to reduce waste, improve quality and minimise the building's carbon footprint. Energy efficient solutions like the AquaForce 30KAV chiller support Carrier’s 2030 Environmental, Social and Governance (ESG) Goals to reduce its customers’ carbon footprint by more than 1 gigaton.

The chillers provide air conditioning for the building’s 333,000 square feet/31,000 square metres of open plan office space, retail and leisure facilities that form the centrepiece of Enterprise City, a new digital technology hub that will be home to creative and media companies.

The ultra-modern 11-storey building, constructed by Lendlease for developer Allied London, was inspired by the industrial warehouses in Brooklyn, New York, and includes a mix of café bars, restaurants and leisure facilities, designed to create a vibrant neighbourhood in which to live and work.

'The work took place at the height of the epidemic and there were a number of design changes along the way, which required the installation team to change plans at short notice,” said Darren Smethurst, NG Bailey's project manager who led the installation. “With support from Carrier, we were able to adapt and still achieve the tight time timescale for installation and completion, to keep the project on track.'

The chillers are equipped with variable-speed screw compressors and dual variable-speed pumps, plus Carrier's proprietary Greenspeed intelligence control system for enhanced energy efficiency. Given the premium application, low operating sound-level was a key requirement, and the units are equipped with bespoke acoustic treatment packages to further minimise noise levels.

Carrier AquaForce 30KAV chillers contribute to building sustainability, determined by BREEAM or LEED, in several ways:

• Enhanced efficiency reduces carbon dioxide emissions associated with the operation of the cooling plant.
• Reduced refrigerant charge and integral leak detection further minimises environmental impact.
• When configured for free-cooling or heat recovery, the 30KAV can further reduce carbon emissions.
• Low-noise operation due to its intelligent inverter control and acoustic treatment results in a more peaceful environment.
