greenBIM is a digital tool for embodied and operational energy analysis in buildings and energy efficiency optimization. To date, greenBIM considers predefined building components and simplified building geometry for an evaluation in an initial building lifecycle stage. Through the CBI Booster, the team aims to further develop the tool and provide detailed material-based information. In that way, architects and planners are enabled to design their own building components, while taking into account environmental aspects and more complex building projects, and moving further in the building’s lifecycle.

Madaster is a cloud-based platform which aggregates information on materials, components and products within a building to generate a material passport. This enables the calculation of, amongst others, the Madaster Circularity Indicator which evaluates the circular performance of a building. During the course of the booster, the aim is to validate the existing Madaster material and product database for the Swiss market and generate a Swiss Material database with average values that represent local conditions.

This team aims to develop and prototype a flooring system that is modular and can be easily disassembled and reused. The flooring system is manufactured using bio-based and carbon-storing material or out of recycled waste. The flooring modules have standardized dimensions, allowing them to be off-site, mass-produced.

HHM has developed a model for designing circular building technology systems based on the 5Rs of material management. Through the CBI Booster, the team aims to test and compare this model to an ongoing conventional building technology project for a residential building. The aim is to understand how its application affects the building, the planning process as well as the life cycle costs and the life cycle assessment.
