• Use of timber is growing, in many
countries 15..20%
• Prefabrication is becoming more popular
• Every country has its own ”wooden
monuments”
• How to make reasonable houses for
masses?
3. ƵƌƌĞŶƚ ƚƌĞŶĚ ŝŶ ŝŶůĂŶĚ
• Timber is on the edge of breakthru
• We have our own monuments, but still
”reasonable for masses” is almost unsolved
• In Finland, the government has launched a
program for use of timber
• Wood is the material that we do not need to
dig! We have plenty of it.

Plus-energy houses
Timber is in a key-role to cost-effective
building
Clever use of different materials
Timber is also needed to create cost-
effective renewable bioenergy

o Increasing percentage of prefabrication
• Moving work from site to manufacturing
plant
• Decreases time on-site
• Decreases quality problems and complains
o Rethinking material usage
• Right material in right place
• Material development
12. ĐĐĞůĞƌĂƚŽƌƐ ŽĨ ŐƌŽǁƚŚ
o New regulations for CO²-calculation
o Increasing energy-costs
• Makes energy-intensive materials more
expensive
• Zero-energy- and plus-energy-systems
require new kind of thinking, that should de
free from conventional manners and
systems

Building from timber is good for
environment, but it has to be cost-
effective to gain its marketshare
The development is based on efficiency,
not just timber itself
In Finland, we have lots of raw material
and knowledge.
Still we have a lot to do!
