We know that buildings use about (40)% of all energy use and we also know that the energy efficiency of buildings can be greatly improved, often just by better monitoring and controls with low capex and fast paybacks. Savings of 20% or more can often be achieved by better control strategies and recommissioning. New design techniques such as integrative design of whole building retrofits can ‚ produce much larger savings. The UK spent about ‚£42 billion on energy in buildings in 2011, about ‚£29 billion in the domestic sector and the rest in non-domestic buildings. ‚ Assuming we can save 20% in non-domestic buildings, which is an achievable target, the value opportunity on offer is about ‚£8 billion per annum, potential savings that could produce an investment return and reduce operating costs for businesses and householders alike. So what needs to happen before we can really exploit this huge opportunity? ‚ Lots of it can be achieved with […]
