What De Groene Jongens does
De Groene Jongens B.V. is a Utrecht-based sustainability consultancy serving the Dutch built environment. Founded in 2016, the firm operates with a multidisciplinary team of 14 specialists and has completed more than 500 sustainability projects over nearly a decade. It advises property developers, municipalities, healthcare providers, construction companies, and commercial real estate investors on integrating circularity, energy efficiency, and health considerations into new-build and renovation projects from the earliest sketch-design phase.
The firm's core service offering is organized around three pillars: sustainable installation design and advisory, building sustainability certifications (BREEAM-NL including In-Use and New Build/Renovation variants, GPR Gebouw as both Expert and Assessor, WELL, and Energielabels), and technical calculations and measurements (BENG, MPG, BCI Gebouw, WEii, TO, LCC, warmteverlies, and luchtkwaliteitsmetingen). Supporting services include reporting on EED audit obligations and information/investigation obligations, subsidy advisory (DUMAVA, MIA/VAMIL), variant comparison studies, circular construction advisory including material passports, and a dedicated sustainability framework for municipal real estate portfolios. The firm uses third-party software tools (VABI Elements and Uniec3) for energy and comfort simulations and does not offer proprietary software.
De Groene Jongens generates revenue through project-based professional services engagements, with pricing quoted per project depending on scope, building type, and certification complexity, and billing structured around multi-year contracts. Its go-to-market is sales-led and expertise-driven, positioning specialists as advisors who engage early in design phases. The firm is a partner in four Dutch sustainability networks: Dutch Green Building Council (DGBC), De Ecolutie, Cirkelstad, and Het Nieuwe Normaal. Named enterprise clients include Louwman, ING, NordCapital, Woonzorg Nederland, Heembouw, Lomans, WA architecten, The Usual Hotel Rotterdam, and Gemeente Dronten.
