National Trust, Wales

Conserving energy and our heritage

Delivery of insulation to Plas Newydd

The National Trust has defied assumptions that historic buildings can’t be retrofitted, cutting energy use across its Welsh properties by a massive 41% over just two years. With over 400,000 buildings across England and Wales having listed status, it's great to have this demonstration that even the most sensitive buildings can be made much more energy efficient. The Trust's success derives from a combination of efficiency measures and a culture change in how energy is managed. As well as cutting down on energy use it has also installed biomass heating, and renewable sources of electricity including solar PV and hydro power, so the cut in CO2 is an even more impressive 46%.
