15. Optimal insulation thicknesses
U-values:
Walls 0,11 W/m2 K (350 mm)
Floors 0,10 W/m2 K (270 mm)
Roofs 0,08 / 0,10 W/m2 K (450 mm / 360 mm)

16. Energy Performance of Building Directive
(EPBD)
The energy performance certificate should be issued almost
for every building

17. Key recommendations
Reduce buildings heating energy
Make the Passive House our
standard choice (mandatory in new
UK buildings from 2013)
Always make building renovations
energy efficient
Make public buildings energy efficient
role models
Strengthen energy saving
requirements in buildings
Promote savings and provide up-front
financing

18. Lets create the better future!
