HEATING AND COOLING SYSTEMS
A conflation of the regulatory and the economic The landscape for anyone designing, installing, and commissioning heating, cooling, and renewable systems is, therefore, changing dramatically, thanks to this conflation of the regulatory and the economic, and the alarming state of global energy markets. There is a clear focus on the future, but with a recognition that buildings must be safer and healthier, must pay their way, and be attractive to potential buyers or tenants now and for the long-term. This means that our industry will have to get to grips with a systems approach that addresses both immediate concerns over running costs and energy supply, with the longer-term goals of delivering Net Zero – but these things are not mutually exclusive.

improving competence and compliance standards will have benefits all round. Lawyers and insurers will obviously have a big influence on the safety agenda, but there will also be considerable commercial incentives for building owners and managers to do the right thing for their occupants and the planet.
Incentivising whole-life performance For example, many building owners are adopting the Australian NABERS model because it incentivises whole-life performance, and therefore drives down the lifecycle carbon. Landlord services in commercial buildings have improved their energy performance by 36% since the Australian government mandated the scheme in 1999. It works because it is in the commercial interests of the landlord to make sure their building has a good enough rating to attract tenants. NABERS ratings cover 86% of the Australian
commercial building stock, and are fully transparent, so there is no hiding place for underperforming assets. This principle is becoming increasingly popular with UK building owners, who are nervous about ending up with ‘stranded assets’, i.e. buildings that will eventually be too expensive to retrofit to meet tightening low carbon standards. Minds are also being focused by the Minimum Energy Efficiency Standards (MEES), which are due to be upgraded this year. Since 2018 a minimum EPC rating of E has been in place for new tenancies, but from 1 April 2023 this will be extended to cover existing leases, making it unlawful for a landlord to let any commercial property with an EPC rating of less than E. The MEES level will then rise to B by 1 April 2030, with landlords given two ‘compliance windows’, starting in April 2025, to achieve it. All properties will have to be at least C-rated by 2027.
