ATP Sustain

What ATP Sustain does

ATP Sustain (legal entity: ATP sustain GmbH) is a Vienna- and Munich-headquartered consulting and special planning firm for sustainable construction and building physics, founded in 2009 as part of the ATP Group network of architecture and engineering companies. The firm delivers advisory and engineering services across the entire building lifecycle — from new construction and renovation through to existing building operation and monitoring — for real estate owners, institutional investors and asset managers, ESG-focused corporations, public sector clients, and manufacturing/industrial companies. Its core service portfolio spans eight interconnected competencies: Building Physics (Bauphysik), Energy & Climate Protection, ESG & Sustainability Consulting, Building Certification, Building & System Simulation, Climate Change Adaptation, Materials & Circular Economy, and Biodiversity & Environmental Protection. The firm holds accredited-partner positions across the major European green building certification systems (DGNB, ÖGNI, SGNI, BREEAM, LEED, klimaaktiv, BNB, ÖGNB) and is an official CRREM partner.

The firm's underlying technology layer is a simulation-driven consulting platform integrating thermal building simulation, HVAC system simulation, CFD microclimate modeling, daylight simulation (sDA/ASE), and PV yield simulation, used to optimize buildings across full annual cycles and to support certification deliverables. ATP Sustain is staffed by an interdisciplinary team of more than 50 specialists covering building physics, energy, ESG, simulation, biodiversity, and circular economy disciplines, and draws on referral flow from sister companies within the ATP Group (Ensphere, Blu-Print, Mint Architecture, ITA Engineering, HGPC, ATP Health) as well as industry associations (DGNB, ÖGNI, CRREM, BREEAM, USGBC, SGNI, klimaaktiv, ÖGNB, GIF, Baukarussell).

ATP Sustain operates a professional services business model with project-based consulting and special planning engagements quoted on an hourly basis (with hourly rates applied even when offered as lump-sum, per AGB) and monthly invoicing against agreed payment plans. Go-to-market is enterprise field sales and advisory-led direct engagement with property owners, investors, developers, and public clients, primarily across the DACH region and Central/Eastern Europe. Pricing is not publicly disclosed, revenue is not publicly disclosed, and the firm is privately held with no external funding rounds, valuing regulatory expertise and long-term anchor relationships (e.g., Swiss Prime Site portfolio certification since 2021) as the principal commercial moats.
