About LCAbyg

LCAbyg is a tool that calculates life cycle assessments for buildings.

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.

Housing construction from 4 to 1 planet: Call for best practise cases

In connection with Realdania and the VILLUM FOUNDATION's initiative Housing construction from 4 to 1 planet, the industry is invited to contribute with the building cases that are most ambitious in terms of reducing climate footprint, and which have the potential to approach absolute sustainability within climate impact. Among those registered, a number of projects will be selected and included in a sample collection of the least climate-damaging housing constructions in 2022. The project includes housing construction, and it is, therefore, possible to register Danish or international projects within multi-story buildings, terraced houses, and detached houses.

 

Join our online information meeting on June 15 from 13.00-14.00. Read more here https://kursus.build.dk/123

The deadline for registration is July 1st, 2022.

CO2 requirements for new buildings from year 2023

On March 5, 2021, several political parties adopted the agreement on the national strategy for sustainable construction. From 2023, requirements for buildings' climate footprints will be phased into the building regulations. This means, among other things, that all new buildings in the future must have a life cycle assessment (LCA). In 2023, new CO2 requirements will be introduced step-by-step.

The development behind LCAbyg

LCAbyg was developed by BUILD (formerly the National Building Research Institute), Aalborg University with financial support from the Housing and Planning Agency (formerly the Danish Transport and Construction Agency). LCAbyg is a nationally freely available tool that was once developed by SBi, now BUILD; for TBST, as part of a construction policy strategy in 2014.
The first version was launched in 2015, and since then, there have been several changes in the user interface and calculation core. LCAbyg is under constant development, with functions frequently improved
and the addition of new features in close collaboration with the industry.

LCAbyg is used for teaching and documentation in public and private sectors. In the latest version of LCAbyg, LCAbyg v5, it is possible to use the voluntary sustainability class (FBK).
