Technical guidance: HVAC and chiller systems
reductions of between 30 and 40 per cent. Among the benefits of chillers, for example, are reduced running and maintenance costs, and increased stability.
What are suppliers, the healthcare sector, and the Government, already doing to help reduce carbon footprint, and what should their priorities be in the future? AdamSpolnik: “As part of the overall Government-backed drive to cut carbon footprint, healthcare establishments have already drawn up, and continue to compile, plans to minimise waste, improve the efficiency of buildings, and reduce travel. By reducing carbon emissions, the health service can, of course, save money that can be put back into patient services. It is the second of the three elements that we are most keen on developing; improving the ‘efficiency’ of buildings. “Ensuring that hospitals are more
carbon-aware will further boost initiatives to ensure that they comply and meet new targets. The healthcare sector is recommending that supplier companies look at the ‘whole life’ cost of their products, and we are doing the same. It is important to ensure that products will be properly maintained over time, rather than simply considering just the initial costs of installing the equipment.
likely to look first at how efficiently, and effectively, procurement or refurbishment of building stock is being undertaken, and at further developing sustainability through measures, which may indeed well already be ongoing, such as reviewing lighting, travel planning, and HVAC system operation.

Governments’ need
for self-sufficiency “There is an increasingly urgent requirement for Governments to become self-sufficient in terms of energy. Russia and Qatar, for example, are able to control the world’s gas markets. They determine to whom they are going to sell their gas supplies, and for how much. The sooner that countries find their own alternatives, the better, and significant reductions in power consumption are going to become more and more important. “In the ‘new healthcare landscape’, of
course, clinical commissioning groups, or CCGs, will be responsible for 80% of the NHS’s budget, and thus have a huge role to play in improving the NHS’s environmental performance. The CCGs are
What do personnel such as healthcare engineers and estates managers need to do to maintain HVAC and chiller equipment so that it performs optimally? AdamSpolnik: “To ensure that equipment runs at optimal performance, such staff don’t necessarily need to follow a daily routine, but they do need to make sure that trained professionals with gas handling certification service the units regularly. At ICS Cool Energy, we stress the importance of having a preventative maintenance contract in place, and do like to see our customers a few times a year.
RichardMetcalfe: “Of course, all F-Gas work and maintenance must be registered and logged for any refrigeration equipment in any industry. All equipment that comes directly into contact with the patient should also be compliant with manufacturing industry standards related to the medical and healthcare industry. “Many buildings in the healthcare sector have ‘inherited’ old equipment, so it really
