Sempergreen Group

What Sempergreen Group does

Sempergreen Group (Sempergreen BV) is a Netherlands-based, privately held provider of engineered vegetation systems for the built environment, organized across three product lines: green roofs, living walls, and ground covers. Its green roof portfolio includes Sedum Original pre-grown blankets, Pitchedgreen systems for sloped roofs (20°–45°), Flowergreen biodiverse roofs, Purple-Roof detention/retention systems that delay stormwater runoff for up to 24 hours, and Solargreen roofs that combine vegetation with vertical bifacial PV panels. The living wall portfolio is anchored by the SemperGreenwall modular system, including the Flexipanel A2 variant — the first living wall system in the market to achieve A2-s2-d0 fire-safety certification under EN 13501-1, suitable for high-rise projects up to 98 meters. Ground cover solutions address tram tracks, roadsides, and public spaces.

The company's commercial model is project-based and engineering-driven. Products are sold through a hybrid of direct sales (with named contacts in the Netherlands, US, and other markets) and a network of certified installation partners, supported by free project advice, water retention calculations, and proposal generation. Pricing is quote-based and project-specific; a Purple-Roof detention layer typically adds $5–7 per sqft to a standard green roof. Sempergreen generates revenue across four streams: green roof system sales, living wall sales, ground cover solutions, and distribution margin from European distribution of Over Easy Solar vertical bifacial PV panels. Customer segments span commercial real estate developers, government/municipalities (waterschaps, Sponge City initiatives), healthcare and education institutions, retail/hospitality, architects/design firms, and infrastructure/transportation operators, with a project portfolio of 100,000+ completed installations across 45+ countries and roughly 10 million sq ft installed annually.
