Global impact of buildings

Buildings account for 40% of the world’s energy use …





… Building energy consumption needs to be cut by 60% by 2050 …



... cut the planet’s carbon footprint by 77% !



Directive2010/31/EU

Sustainable Future

The architects’ responsibilities• Provide correct information about energy performance• Consider optimal combination of improvements

• Use renewable and district energy sources
