  1. 1. Enhancing building energy certificates by analysing data stored in the public register of Catalonia Lluís Morer i Forns Catalan Institute of Energy (ICAEN) Barcelona, Catalonia
  2. 2. 2018 • Energy consumption building = 30% • EPC A, B i C <5% All building 2019 New buildings  EPC A Renovations  nZEB? ENERGY PERFORMANCE CERTIFICATES AT CATALONIA 900.000
  3. 3. EPC RELATED TO BUILDING REGULATIONS
  4. 4. THIS IS OUR GOAL AND ALSO THE OBJECTIVE OF THE EPC FROM OUR POINT OF VIEW • nZEB • Electric vehicle (electric battery) • Renewables (solar photovoltaic, thermic, heat pump)
