What Cluster Eco-construction asbl does

Cluster Eco-construction asbl is a Belgian non-profit association (asbl) founded in 2003 and headquartered in Namur (Suarlée), Wallonia. It is the official eco-construction cluster recognized by the Walloon Region and a member of the French Réseau Bâtiment durable animated by Ademe. The organization functions as a professional network and business development hub, aggregating approximately 300 reference actors across architects, producers, constructors, engineers, merchants, trainers, and researchers, with the stated mission of dynamizing the eco-construction market in Wallonia.

Its core service portfolio spans certification, training, networking, and resource distribution. The flagship certified offering is the Label Produit Biosourcé, an officially recognized Walloon certification that quantifies the bio-sourced content of construction materials and unlocks up to 36% premium subsidies on renovation insulation work. Complementary products include the Maison Virtuelle (a 360-degree virtual tour of an eco-renovated house), the Maison Interactive (an interactive demonstration of eco-renovating a pre-1945 Walloon house), the Cluster Academy training program, monthly 5à7 networking events, the annual Cluster Night, international business development missions, and advisory services for municipalities. The cluster operates from the UP STRAW building, a wood-straw construction headquarters with 40% lower carbon impact than a conventional building, serving as a live demonstration of its expertise.

The business model is multi-stream and non-commercial: recurring membership fees from professional members, training and conference fees through Cluster Academy, certification fees for the Label Produit Biosourcé, public-sector support tied to its Walloon Region recognition, and grant funding from a portfolio of 11+ European projects (CrossCircular, Build-value, UP-Straw, GROOF, etc.). Go-to-market is community-led: direct membership enrollment, self-serve professional directory for homeowners, and event-based member engagement. The organization employs approximately 25 staff and does not disclose revenue.
