STAR*track is a 3-year Coordination and Support Action (CSA) funded by the European Union (EU) under Horizon Europe (HE) within the Built4People Partnership. STAR*track aims at expanding the Built4People Innovation Cluster (B4PIC) Network developed in the HE project Nebula and strengthening and supporting B4PICs and their members to deliver sustainable and people-centric innovation and accelerate uptake by regional value and supply chains. Built4People (B4P) is a co-programmed public-private partnership in Horizon Europe’s Cluster 5 (Climate, Energy and Mobility) that brings together the European Commission (EC) and two leading associations — ECTP and WorldGBC Europe — with a membership base of actors in the built environment with the main goal to accelerate innovations towards decarbonisation and the people-centric transformation of Europe’s built environment.
