6. Responsible sourcing Now covers all materials not just timber
Different documentation and evidence required for various materials

Frame
Ground floor
Upper floors (including separating floors)
Roof
External walls
Internal walls (including separating walls)
Foundation/substructure
Staircase
100% of timber in elements must be legally sourced

8. What materials are considered
Only the following materials are assessed in the calculation of points
Brick (including clay tiles)
Composites
Concrete (including blocks, tiles etc.)
Glass
Plastics
Metals (steel, aluminium etc.)
Stone
Timber

12. And the future? Ecopoints per m2 to eventually replace Green Guide
Rewards both reduced environmental impact and efficient design
Still based on Ecoprofiles
Ties in with new European Standards
Needs better design tools e.g. smarter CAD

13. Good luck!
