Welcome to BUILD UP, the European web portal for energy efficiency in buildings. As you know, buildings account for 40 % of Europe's energy use and a third of its greenhouse gas emissions. If we want to transform our society into an energy efficient and decarbonised one, energy-intelligent buildings will play a vital role. Therefore I appreciate a lot this platform where policy makers, building professionals and building occupants can get together. I would like to encourage all of you to share your valuable knowledge on how to reduce energy consumption in buildings. Let us work together towards cleaner and more energy intelligent buildings for the future.
