The focus for improved energy efficiency in commercial property has so far mainly been on new buildings. The introduction of minimum energy performance standards in Part L of the Building Regulations and their tightening in 2006 have led this agenda. Looking ahead, more challenging standards proposed for the Building Regulations to achieve the government's target for all new non-domestic buildings to be zero carbon by 2019 mean that the industry's attention will continue to focus heavily on new buildings.rnHowever, new buildings only account for 1-2% of the total building stock each year, meaning that, if the government is to get close to its target of cutting carbon 80% by 2050, significant CO_2 reductions will need to come from existing buildings, especially the commercial sector.
