For sustainable building and the role of biomaterials. Lau Raffnsøe, Center for Buildings Climate Impact/Green Building Council Denmark.
The Green Building Council is a non-profit membership organization with 800+ members across the Danish construction and real estate industry. More than 50 employees in Copenhagen and Aarhus work on a green building mission:
With proven evidence as a starting point, we set a common ambitious direction for a sustainable future in construction, buildings and urban development - economically, socially and environmentally.
Lau Raffnsøe introduces the Danish requirements to new buildings that must be documented with a GWP calculation (i.e. a life cycle assessment, LCA).
New buildings over 1.000 m² must comply with a limit value of 12 kg CO2-eq./m²/year
In the coming years the total CO2e consumption over the lifetime of the building - the LCA - will be met by a significantly lower limit value. See the table below.
Lau Raffnsøe also presented LCAbyg, a tool that calculates life cycle assessments for buildings and is free to use https://www.lcabyg.dk/en/.
With LCAbyg, you can calculate a building's environmental profile and resource consumption. You enter information about the building parts and possibly the building's energy consumption. The program automatically computes the results in a table and generates figures and a summary report.
The calculations of environmental impacts are performed over the entire life cycle of the building, including the procurement of raw materials, production of building materials, energy and resource consumption during operation and maintenance, and disposal and possible recycling of building parts and building materials.
