Open innovation in sustainability and circular construction



From October 25 to 27, BESIX organized its first hackathon dedicated to the construction sector. Hack2Build invited employees of the BESIX Group, but also start-ups or companies with great sustainable ideas in the field of construction and real-estate. 3E was part of the team that won the hackaton.

BESIX is the largest Belgian group, operating in the construction of buildings, infrastructure, environmental projects and roads. BESIX is also active in the production of raw materials, facility management, real estate development and concessions.

During 3 days, more than 40 participants gathered in the Château de la Poste in Namur (Belgium) for Hack2Build. The BESIX innovation team selected the challenges to be solved during the hackathon and crystallised the challenge around two themes: sustainability and circular construction. The main goal was to improve the industry and change the world with new solutions or new business models to adopt.

A challenge tackled by the winning team during Hack2Build was to find the right balance between profitability, comfort and simplicity during the building’s life cycle. Their business model, ‘Living as a service’, proposes lower operational costs of the building through smart design, and making the client’s investment more profitable in the long term.

The winning team was composed of Lukas Pinnoo (BESIX), David Appelfeld (Knauf), Antoon Soete (3E – Wattson), Sunita Van Heers (3E), Kris Blykers (A-tract Architecture) and Bertrand Dury (AGC). An inspiring way for innovation and entrepreneurship to create sustainable solutions in the construction sector.
