- Wood
is carbon neutral (Because trees absorb CO2 as they grow). In fact,
because of the carbon sink effect of the forests, wood from sustainably
managed forests can actually be better than carbon neutral.
If you use enough wood, a building can be carbon neutral – or
better!.
- Wood has the lowest embodied energy of any mainstream building
material A tonne of brick requires four times the amount of energy
to produce sawn softwood, concrete five times, glass six times, steel
24 times and aluminium 126 times.
- Using wood instead of other building materials saves on average
0.9 tonnes of carbon dioxide per cubic metre, 3 tonnes of CO2 can
be saved by using timber frame from the 20 tonne CO2 footprint of
a typical 3 bedroom detached house.
Increasing the timber content,
including softwood cladding, can reduce the footprint to 2.4 tonnes – a
total reduction of 17.6 tonnes CO2.
- Wood has the best thermal insulation properties of any mainstream
construction material
5 times better than concrete
10 times better
than brick
350 times better than steel
- Certified timber and timber products have Environmental Profiles
which can contribute to achieving higher Green Guide ratings and
higher star ratings in the Code for Sustainable Homes
- Trees absorb one tonne of carbon dioxide for every cubic metre’s
growth
