What Green with IT does

Green with IT e.V. is a Berlin-based, registered non-profit association (eingetragener Verein) that operates as a coordinating network for 19 specialized member companies delivering digital solutions to the German housing industry (Wohnungswirtschaft), real estate operators, and municipal utilities (Stadtwerke). Its core concept, the Autarke WoWi-Cloud, bundles BSI-compliant secure data management, CO2-equivalent documentation, legionella protection, and 24/7 technical services into a landlord-facing digital ecosystem, while member-provided products such as the WoWi-App (BSC Computer), en:key self-learning room control (Kieback & Peter), sub-metering (Innotas), neighborhood simulation (Ingenieurbüro Franke), and digital neighborhood management (DSC) address the technical layers of fossil-free, zero-emission neighborhoods.

Underlying technology spans Smart Meter Gateways, IoT-based energy management, self-learning heating control algorithms, building and neighborhood simulation, and BSI TR 03109-5-compliant data architectures. Pilot deployments with BBB Management Campus Berlin-Buch, ABG Paradies Berlin, GWG Lübben, and Wobau Eisleben generated documented outcomes of approximately 30% heating-energy savings against reference buildings and tenant heating-cost reductions from €716 to €531, which the association leverages as proof points.

Green with IT e.V. is not a commercially funded company: it is financed 50/50 by federal and state GRW (Gemeinschaftsaufgabe Verbesserung der regionalen Wirtschaftsstruktur) funds, with member companies retaining their own commercial operations and revenues. The go-to-market motion is project-based consulting supported by pilot references, distributed through the association's website intake, events, content channels (blog, newsletter, enervlog.de vlog), and the embedded sales channels of its 19 member companies. Pricing is not publicly disclosed. The WohnZukunft project, recognized as the first German deep geothermal major project, with its RENEWAC follow-on funded under Berlin's Deep Geothermal Innovation Fund, extends the platform's reach into district-scale decarbonization.
