One method for tackling this inefficiency is through renovation. However, the EC has calculated that only 0.4-1.2 percent of building stock across the EU is renovated each year.

Another approach, taken by the EU-funded TRIBE project, is to encourage building users to change their behaviour. TRIBE created a management pack, which included an energy audit, a virtual pilot's design (energy model of the real building), an ICT deployment plan, user engagement campaigns and funding schemes. Perhaps the most innovative aspect was the creation of a social game, available for iOS and Android devices, linked to data collected from five European pilot buildings, including a university, public offices and social housing.
