Green Building Partners

What Green Building Partners does

Green Building Partners was a Finnish building lifecycle services firm providing environmental, energy, and life-cycle services to construction projects and existing building stock. Its core services spanned property condition assessments, energy performance certification, indoor air quality measurement, structural inspections, moisture and radon investigations, sustainability and EU taxonomy compliance, BREEAM/LEED environmental certification, construction supervision, and technical property management consulting. The company served three primary segments: residential homeowners and home buyers (pre-purchase inspections, energy certificates, radon measurement), corporate and institutional property owners, managers, and housing cooperatives (full lifecycle and sustainability services), and construction companies and developers (construction management, quality control, moisture and cleanliness coordination).

In 2024, Green Building Partners was merged with Raksystems, EcoReal, KnowTek, and Suomen radonhallinta to form Sustera Finland, a unified subsidiary of Sustera Group employing over 400 professionals. The consolidated entity operates under two go-to-market tracks (Kodit/residential and Yritykset/commercial) delivered through direct sales (a national phone service line and online quote requests) and inbound self-service inquiries. Revenue is generated on a fee-for-service, quote-based model for both B2B and B2C clients, with no public pricing disclosure. Digital products including KotiApp (a residential building condition and energy monitoring application) and Älysertifikaatit/Smart Certificates (digital sustainability certification) supplement the core service offering. The company holds ISO 9001 and ISO 14001 certifications from DNV, reports a customer NPS of 71, and measures a carbon handprint of 51,756 tCO2e and a well-being footprint of 196,000 people positively impacted.
