CSD Engineers

What CSD Engineers does

CSD Engineers (legal entity: CSD Ingenieure GmbH Deutschland) is a Berlin-headquartered civil engineering consultancy founded in 1970, specializing in sustainable construction and building physics. The firm operates two German offices — a headquarters in Berlin (Köpenicker Straße 154 a) and a second office in Mannheim (P6 22) — and is a wholly owned subsidiary of the Swiss group CSD Ingenieure AG, which maintains over 30 business locations across Switzerland, Belgium, Germany, and Italy. CSD positions itself as an environmental pioneer and delivers eight core service lines: Nachhaltiges Bauen (sustainable building consulting with DGNB/LEED/BNB certification), Bauphysik (building physics), Simulationen (dynamic building simulations including thermal, daylight, and airflow), Energie und Klima (energy concepts, audits, and a proprietary Gebäudebewertungssystem building assessment system), Schadstoff- und Umweltgutachten (hazardous substance and environmental assessments), Umwelttechnik (environmental technology including water and waste), Geothermie (geothermal consulting), and Klimarisiken und Mikroklima (climate risk and microclimate analysis tied to DGNB V23 and EU Taxonomy).

The firm's offerings are entirely service-based professional consulting — no software, SaaS, or productized platform. Revenue is generated through project-based engagements with enterprise clients, typically won via competitive tender or direct relationship; pricing is negotiated per scope. CSD is accredited to audit and certify against the three principal European green building standards (DGNB, LEED, BNB) and has accumulated a portfolio of certifications including DGNB Platinum (JFK Haus MK7) and multiple DGNB Gold ratings (Zalando Headquarter, Land BA, Frankfurter Allee, Europaplatz high-rise, New Courts Gerichtstraße, Stralauer Platz) along with BNB certifications for federal buildings. Notable clients include CA Immo, Zalando, HB Reavis, Becken Development, Potsdamer Volksbank, Berliner Volksbank, Roche, the Bundesamt für Bauwesen und Raumordnung, the Bezirksamt Treptow-Köpenick, Max-Delbrück-Centrum, and DESY.

The German subsidiary operates with 11–50 employees under Managing Director Sven Wünschmann and Geschäftsleiter Deutschland Tobias Klingbeil, with department heads Uta Ehrhardt and Moritz Diesner leading the Mannheim sustainable construction practice. The business model is direct enterprise field sales — Geschäftsleiter and Abteilungsleiter drive business development, with projects executed by interdisciplinary teams. Distribution is single-country domestic (Germany), though the parent's pan-European footprint and intra-group referral network provide latent cross-border reach. CSD's near-term strategic posture emphasizes bundling climate risk and microclimate services with traditional certification work to capture regulatory tailwinds from EU Taxonomy disclosure and DGNB V23.
