Monitoring the use of wood consumption in construction and determination of the potential for CO2- sequestration - KlimaBau
Project
Project code: 28WB403201/02
Contract period: 01.10.2014
- 30.09.2017
Budget: 304,410 Euro
Purpose of research: Inventory & Assessment
Construction is the largest segment of wood consumption. Therefore, buildings play an essential role for CO2-
sequestration through wooden products. Construction is structured in different maintenance groups with unequal
utilizations of wooden products. Thus, the structure of wood consumption in different maintenance groups is an
important decision criterion for politicians and investors to support CO2-sequestration efficiently.
The „KlimaBau“-project is supposed to create an empirical foundation to analyze the impact of wood use in
construction on direct carbon sequestration. The project considers the utilization of wooden products for new
buildings and for remodeling as well as the construction segments of residential and non-residential buildings.
The great challenge of investigating complex, technical data will be solved by building specification descriptions
and architectural work descriptions. Within the project “Wood utilization in construction (2013)” 550 new buildings
were documented. This is a solid basis for a constantly actualized data base of wood utilization in construction.
200 more new buildings are documented via building specifications from architects. Thereby, the quality of
the dataset will be improved.
To document wood utilization in residential remodeling (about 50% of wood utilization) 10.000 households are
inquired with a mail panel. In the segment of non-residential remodeling (below 10% of wood utilization) a
calculation model based on indicators (e.g. weighting schema of construction prices, new buildings, recorded
measures) is developed, that estimates this small segment with acceptable correctness.
In order to achieve a continuous reporting system, the statistic on construction development (construction volume
and activity) will be combined with empirical studies. Empirical studies and construction statistics ensure a
continuous yearly determination of direct CO2 –sequestration in construction. New datasets will be added and
older ones will be eliminated. This method complements Life-Cycle-Analysis-methods for single products with
an actual documentation of the whole construction market. Hence, this could be a path-breaking method for
other countries or for a complete documentation of all materials in buildings.
