Sustainahaus (legal entity PT Solusi Rumah Hijau) is a privately held sustainability consultancy founded in 2020 and headquartered in South Jakarta, Indonesia. The firm specializes in green building certification advisory and corporate ESG services, operating across Asia Pacific with projects delivered in eight countries (Indonesia, Singapore, Malaysia, Cambodia, Philippines, Vietnam, Mongolia, and others) and a roster of 50+ enterprise clients and 90+ projects. Service delivery is anchored by credentialed positions including EDGE Premier Service Provider status with IFC/World Bank Group, licensed AA1000AS Assurance Provider status since 2022, and memberships in the Green Building Council Indonesia and U.S. Green Building Council.

The company's product surface is organized into two integrated portfolios. The Green Building portfolio covers advisory and third-party audit for rating systems including EDGE, Greenship, BGH (Indonesia's government green building scheme), LEED, WELL, Fitwel, and EarthCheck Design, with capability as both EDGE Expert and EDGE Auditor. The Corporate ESG portfolio spans sustainability reporting (POJK 51, GRI, TCFD, IFRS S1/S2), GHG accounting under GHG Protocol and ISO 14064, AA1000AS assurance, GRESB advisory, ESG risk rating, and net-zero strategy development. A training line delivers EDGE Expert Training jointly with Sintali-SGS, including cross-border delivery into Mongolia in December 2024.

Sustainahaus generates revenue through custom-quoted professional services engagements with enterprise clients — primarily real estate developers, asset owners, corporations, and institutions — sold through direct enterprise sales, EDGE platform referrals, industry events, and network-driven leads. The firm holds no public listing, has not disclosed external funding rounds (appearing bootstrapped), and operates with a team of approximately 14 employees including credentialed green building and ESG specialists.
