Parallel session 10: Resource efficient buildings, infrastructures and building solutions

Construction industry are resource intensive. 50% of resources used in various activities during construction are extracted from Earth. The industry cumulatively releases 40% of greenhouse gases and 50% of waste generated. Therefore it becomes important to tackle the vices in the industry for a green future.

The session was chaired by Alexa Lutzenberger. The first speaker Cédric de Meeûs, Vice-President, Group Public Affairs & Government Relations, spoke about reinventing the construction industry. The goal set by him was a net zero carbon industry. Shelter is an essential necessity yet 1.6 billion people in the world lack adequate housing. When looking at the solutions, resources that are flexible and efficient are the need of the hour. Policies framed that are needed for resource efficient construction should look into: material neutrality, life cycle performance and demand pull measures.

The second speaker was Hubert Rhomberg, Managing Director of Rhomberg Holding introduced the work of digital twin. The digital twin of the building is an AI based optimisation process considering several scenarios and parameters and also allows to extract exact amount of material and costs. It can be utilised by the people working on a new project saving their time drastically. A new funding model proposed in which a building is considered as a material bank and while dismantling all the material can be reused.

The third speaker Klaus Dosch, Director of Factor X talked comprehensively about three turnarounds in construction as energy, climate and raw materials. Each project needs to look into design, list of resources and dismantle manual. Each new building should have a Resource-Score, consisting of three components- climate-score, material-score and energy-score. The session concluded with a QnA answered by all the speakers.
