Climate impact of industrially produced wooden apartment buildings
The results show that industrially produced wooden apartment buildings have a relatively low climate impact 126 - 189 CO2e/m2 GFA. In comparison with other apartment buildings in concrete, the study shows that buildings in wood have a lower climate footprint. The climate impact of the buildings included in this study has also been compared to previously conducted climate calculations for wooden buildings with the same boundaries. The results show that the volume houses are in line with the results of previous studies on volume elements in wood.
This study has also identified measures to further reduce the climate impact of wooden buildings. The choice of supplier plays a major role in the climate impact of buildings. The study investigated how the climate impact can be reduced by selecting specific suppliers with a low climate footprint for materials that traditionally contribute a high share of the climate impact (concrete, insulation, plaster and reinforcement). Another climate-saving construction measure was to replace the bathroom pod with a traditional building system for bathrooms. The results showed that the climate impact can potentially be reduced by 30% when specific suppliers are chosen. In addition, if the bathroom can be climate optimized, the climate impact can potentially be reduced by another 18%. Climate saving measures have the potential to almost halve the climate impact of a studied wooden volume house.
