The high-efficiency system contributed to the building earning an Excellent rating from the Building Research Establishment's Environmental Assessment Method (BREEAM). BREEAM is the world’s leading sustainability assessment method for master planning projects, infrastructure and buildings. Consultant Designer Group specified a total of 10 roof- mounted Toshiba outdoor VRF condensing units, connected to 135 ceiling-mounted slim-ducted indoor units, to provide heating and cooling for upper storeys, and a digital inverter condensing unit and hi-wall fan coil unit for the basement, with equipment installed by contractor London AC Ltd. An internal view of offices at 120 Cannon Street Study shows benefits of Carrier Transicold technology A Carrier Transicold customer in the UK has shared the results of a multi-year refrigerant performance evaluation on its range of truck and trailer refrigeration systems, demonstrating that a combination of R452A refrigerant and Carrier’s all-electric E-Drive technology delivered close to a 50% reduction in carbon emissions from its units. The evaluation was based on refrigerant use and leakage across the customer’s fleet of more than 2,000 Carrier Transicold Vector trailer refrigeration units and engineless Iceland and Syberia systems. Over four years, approximately 1,118 metric tonnes of carbon dioxide (CO 2 ) emissions were saved, equivalent to the carbon removed by more than 18,486 trees over a 10-year period. Introduced more than 20 years ago, the E-Drive system removes mechanical transmissions found in belt-driven truck and trailer refrigeration systems to transform engine power into electricity via generator, thus reducing risks of leaks and emissions. The technology significantly cuts fuel consumption, resulting in both a lower carbon footprint and quieter operation compared to diesel engine sound output. E-Drive allowed for the development of a fully hermetic scroll compressor and economiser in the Vector units, creating a closed loop refrigeration system capable of operating ultra-efficiently on both diesel and electric power. E-Drive’s all-electric technology has allowed Carrier Transicold to deliver industry-changing technology to help fleets significantly reduce their environmental impact, aligning with Carrier’s 2030 ESG goals to reduce its customers’ carbon footprint by more than one gigaton. The system was subsequently embedded into the company’s ECO-DRIVE power module, which converts power from the truck’s own engine into electricity to drive its range of engineless refrigeration systems.
