West London hospital is England’s most environmentally unfriendly

Chelsea and Westminster Hospital has been found to be the most environmentally unfriendly in England, according to data from NHS Digital.

The west London hospital produced 15,510 tonnes of carbon emissions during 2015/16 – 278 per cent more than its nearest worst offender Northwick Park and St Mark’s.

NHS Trusts have been tasked with reducing their carbon emissions by 26 per cent by 2020 and by 80 per cent by 2050 as part of the Climate Change Act.

So what areas within hospitals and other healthcare facilities should NHS Trusts target? Lighting is a major source of electricity use, but what about heating, ventilation and air-conditioning (HVAC) systems?

Electric motors driving fans and pumps within HVAC systems are the largest consumers of energy, which is why installing variable-speed drives in hospitals offers significant savings.

VSDs provide electric motor control which allows HVAC systems to run below full capacity whilst consuming less power. It’s estimated that hospitals currently using electric motors that aren’t speed controlled could cut their running costs by as much as 60% by installing VSDs.

Meanwhile, advancements in ultraviolet-C (UVC) light technology enable building and facilities managers to install air and surface disinfecting equipment within the air handling unit (AHU) of an HVAC system.

One such system is CoilCare® from Gibbons Ultraviolet Solutions, which eradicates mould, bacteria and viruses from the cooling coil of an AHU, ensuring air circulated round areas such as waiting rooms, operating theatres and wards is clean, healthy and free of contaminants.

The continued use of CoilCare® can also significantly improve AHU performance, which in turn reduces energy consumption and helps carbon emissions reduction targets to be met.

Along with the innovative CoilCare system, Gibbons stock a comprehensive range of ABB drives, electric motors and HVAC equipment, with installation, commissioning and technical support available from our engineers. For more information on any of these products, call us on 01621 868138 or email
