EAE’s Energy Efficiency Guide is a meta-study that summarises relevant facts and figures about the energy efficiency of Europe’s building stock, relevant legislation, technical developments and how ETICS contribute to achieving Europe’s environmental, economic and social objectives. It condenses the evidence of numerous global, European and national scientific studies and provides recommendations on what can be done to triple the number of buildings undergoing deep or staged deep renovations or new buildings to become net carbon neutral by 2050.
