2 Energy Efficiency in Buildings Buildings in Europe 40% Energy Demand 36% CO2 Emissions TARGETby IEA by 2050: Reduccion of 77% of the CO 2 emmisions Energy Performance of an average European building is poor. The majority of energy in a building is spent to satisfy heating and cooling demands ECOFYS estimate that the addition of thermal insulation to existing buildings in Europe could decrease current building energy costs and carbon dioxide emissions by some 42%or 350million tonnesof CO2emissions

3 Traditional Building Insulation Materials HOW TO IMPROVE ENVELOPE INSULATION? Conventional Insulation Materials: Increasing the thickness of the insulating layers. Insulation materials Thermal conductivity [W m -1 K -1 ] Mineral family Polystyrene-EPS Polystyrene-XPS Polyurethane foam SPACE LIMITATIONS: 20/30 cm thick insulation layers are common in buildings, often resulting in: Bulky constructions, Difficult detailing, Loss of space.
