1. Eco- and Energy-efficient
wood constructions
Univ.-Prof. Dr.-Ing. Stefan Winter
FiDiPro Professorship Aalto University

2. Energy and resource efficiency is the
leading condition to reach a real
sustainable economy based on oil,
gas and coal independent energy
supply!

3. What are the possibilities
and the responsibilities of
the Building Sector?
Univ.-Prof. Dr.-Ing. Stefan Winter
FiDiPro Professorship Aalto University

4. Increase energy- and resource-
efficiency in the building sector...
Faktor
10
Heat-energy consumption

5. ...by renovation of the existing
building stock...

6. ...and new low-energy, passive-
house or even Plus-Energy
buildings...

7. ...with proved carbon footprint etc.
WOOD IN CARBON
EFFICIENT
CONSTRUCTION

8. Is timber able to help to
generate solutions?

9. YES !
+ Sustainable Material
+ carbon storage
+ low thermal conductivity
+ moisture buffering
+ high heat capacity
+ excellent weight-to-strength ratio
+ embedded energy
+ high recycling potential
etc.,
Univ.-Prof. Dr.-Ing. Stefan Winter

12. Some examples:

13. Dry structures – No mould!
The three most important reasons
+ Built-in moisture due to wet building
materials and wetting during erection
++ Convection
+++ Driving rain
low-2-no - Diffusion

14. How to avoid?
Accurate detailing and
second defense lines!
No need to „re-invent“
everything again!

18. Prefabrication, Quality management and
third party control!
+ Complete planning before working!
+ Teamwork of planners – architects,
structural engineers, building services
+ Airtightness check – Blower Door control
+ Production control, incl. third party control
+ Fire safe construction control
+ Quality label –
checked building quality
+ Transparent Life Cycle Assessment
+ Eco label with focus on energy-,
resource- and carbon footprint
assessment

19. Third party control!
