EnergyEffizienz

What EnergyEffizienz does

EnergyEffizienz GmbH is a German energy consulting firm founded in 2010 and headquartered in Lampertheim, Hessen. The firm delivers advisory services across three customer segments: municipalities and public institutions (its primary vertical, for which it provides Kommunale Wärmeplanung, Klimaschutzkonzepte, Klimaanpassungskonzepte, Quartierskonzepte, Sanierungsmanagement, ISEK, Energiemanagement and Kitas/Schulen Energiesparmodelle), companies and businesses (BAFA-subsidized Energieberatung plus Neubau- und Sanierungsberatung), and private individuals (energy-efficient new build, renovation consulting and Energieausweis). Its flagship technical asset is Q-SWOP (Quartiers-Strom-Wärme-Optimierung), a proprietary district-level energy supply optimization tool co-developed with RWTH Aachen and the city of Lampertheim during the BMWI-funded Modellstadt25+ project (2012-2017) and validated in ongoing measurement-technology pilots in four model districts since 2018.

The company monetizes almost entirely through professional-services and managed-services revenue: project-based consulting fees for municipal advisory, district and heat-planning projects, with a large share of municipal work heavily co-funded by federal and state subsidy programs (BAFA up to 80%, KfW, Kommunalrichtlinie up to 95%, with municipal co-contributions starting from roughly €2,000 for district concepts and €1,000/year for four-year school programs). Corporate engagement is offered as multi-year BAFA-subsidized contracts, while private-customer work includes a free initial consultation. Go-to-market is sales-led and direct: dedicated contact lines for Kommunalberatung versus Energieberatung, website lead capture, a LinkedIn presence, and event-driven outreach through public presentations and moderation of municipal energy working groups and citizen participation processes. EnergyEffizienz is a private GmbH subsidiary of naturstrom AG, with no disclosed outside equity funding, and operates with approximately 26 multidisciplinary specialists across environmental and energy engineering, geography, architecture, urban and transport planning, economics, pedagogy and certified building energy consulting, having completed over 250 projects across 10 German federal states.
