Last week, the NTN Innovation Booster – Circular Building Industry, empowered by Innosuisse, held its very first pitching event, where 8 teams presented ideas for projects to accelerate the transition of the Swiss building industry towards a circular economy. Each team was given 3 minutes to pitch their ideas, followed by a short Q&A from a panel of experts. The jury members are experts in the field of construction, sustainability and innovation and provide an independent perspective from industry, academia and the public sector.

Expert Jury

The jury selected the following 4 projects to receive funding as part of the CBI Innovation Booster:


Fachhochschule Nordwestschweiz (FHNW), Institut Nachhaltigkeit und Energie am Bau (INEB)

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.

Helvetization of the Madaster database

Madaster Services Switzerland

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.

Circular flooring system

Aeternum AG

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.

Circularity in building services planning - opportunities, costs and business models


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.

The selected teams will receive 20,000 CHF to develop and test their ideas within the upcoming months. The CBI Innovation Booster team will support the innovation teams on this journey by providing methodological and technical support through workshops and individual exchanges focusing on design thinking and the particularities of circularity in the building industry. Applicants that have been unsuccessful this round have received feedback and are encouraged to reapply to the next open call.

The CBI Innovation Booster, empowered by Innosuisse, is a 4-year initiative and will thus operate from 2022 till 2025. Due to the large number of applicants to the first call, we have already launched our second call on Jointcreate. Jointcreate is the innovation platform used by this and other Innovation Boosters to publish calls, engage the public and collect project ideas and applications. The upcoming call for projects closes on September 2nd and the project pitching session will take place on the 22nd of September. Similar to last week`s pitching session, the applicants will pitch their ideas and an expert jury will evaluate the ideas and select the most promising projects.

The NTN Innovation Booster – Circular Building Industry is looking for radical solutions, from new materials to new business models, that reduce the raw material consumption and negative environmental impact of the building industry. If you have any innovative ideas and solutions related to circular economy in the building industry, apply to the upcoming call so we can support you bring your idea closer to market and connect you with relevant partners and stakeholders.
