1 Mikko Viljakainen (Arch, Lis. Tech) Managing director, Finnish Wood Council 2015 Wood Symposium, Vancouver THE RENEISSANCE IN FINNISH INDUSTRIALIZED TIMBER CONSTRUCTION METHODS Mikko Viljakainen

2 Europe can be divided into three geographical markets Differences in company structures and customer demand Finland 2014 Population Total solution New residential construction < Block of flats ~ Engineered and erected Product with added features Mikko Viljakainen

3 Challenges Strict regulations Urban focus Low tech image and no R&D Labour intensive on site Lack of skilled labour Low productivity Product polarisation Low prefabrication Production orientation Poor quality 2/3/2015 Mikko Viljakainen High costs and prices Environmental footprint

4 Need for a change provides opportunities! Mikko Viljakainen

5 The biggest potential for wood is where the decisions are made professionally and where the buildings are big Puun Market osuus share of runkorakenteissa wood in frames % Puun Market osuus share of ulkoverhouksissa wood in facades % Markkinoiden Total potential kokonaisvolyymi (1000m3) (1000 m3) Source: Tilastokeskus, Rakentamisen tilastot.
