A commercial TermoDeck building in Leeds has been awarded the highest ever BREEAM rating - 87.5%.

According to calculations undertaken by King Shaw Associates, a leading building services and environmental consultancy, the new building will produce just 22kg of carbon dioxide per m2 per year and will emit 80% less carbon than a conventional model office building.

Our initial calculations showed a demand of about 150kW of cooling", Doug King says, "but when you take into account the night cooling using TermoDeck, the cooling load can be reduced to about 50 kW".

BREEAM is the world?s longest standing and most widely used environmental assessment method for buildings. It is a tool that allows the owners, users and designers of buildings to review and improve environmental performance throughout the life of a building. (BREEAM = BRE Environmental Assessment Method)
