About the project

Property owners, developers and contractors are investing resources in creating well-developed BIM models in their construction projects. At the same time, there are requirements to calculate the climate impact in different construction phases. This project aims to create a scalable flow to enable climate calculation based on BIM models.

Climate calculation is a central task in the construction industry. The construction and real estate sector accounts for over 20 per cent of the total greenhouse gas-emissions in Sweden. To move towards a reduced climate impact from buildings during construction, a new law on climate declaration of buildings will be introduced in January 2022.

The transfer of information between the BIM model and climate calculation tools is a known problem, which has been studied previously. One conclusion is that standardization is the most promising solution. Standardization will however be fragmented and remain so for a long time. There are no effective methods for making full use of the information contained in today's BIM models.

In recent years, several pieces of the puzzle have come into place in machine learning and AI in Sweden. By creating a combined solution, which benefits from a rule-based material interpretation and in some cases use AI, the project will contribute with a new method for climate calculation from BIM model. The project will also set up a Knowledge Portal to spread knowledge about climate calculations from BIM models.
