What Energie Consult does

Energie Consult is an independent engineering office for energy consulting headquartered in Koblenz, Germany (Rhineland-Palatinate), founded in 1990 by Klaus Haars, a physicist and engineer. The firm delivers a portfolio of energy-related professional services to enterprise clients, municipalities, churches, real estate companies, and property managers, with a concentration in the Rhineland-Palatinate, Rhine-Main, and Main-Taunus regions of Germany plus selected international development projects across Africa, Asia, Eastern Europe, Latin America, and the Middle East.

Core offerings include energy certificates, energy audits compliant with EDL-G and DIN EN 16247, energy management systems per DIN EN ISO 50001, energy controlling, and structured energy efficiency weeks. The firm is BAFA-registered for federal energy audit eligibility and operates as a long-term adviser to KfW on energy efficiency programs. To date it has issued more than 300 energy certificates covering approximately 100,000 square meters of floor space. Notable clients include Deutsche Bank, Lufthansa, Siemens, Fraport, ZDF, Commerzbank, DekaBank, Europäische Zentralbank, Stadt Frankfurt, Umweltbundesamt, and Continental Teves, among others.

The business operates as a project-based professional services consultancy with direct client engagements and episodic audit, certificate, and management mandates rather than a subscription or platform model. No proprietary software, AI/ML systems, or external funding rounds are disclosed; the firm's value proposition rests on credentialed expertise, regulatory qualification, and established client relationships across German enterprise and public-sector accounts.

Broad incumbents

• Fraunhofer Institute for Energy Economics and Energy System Technology (IEE): German applied research institute specializing in energy economics, efficiency, and renewable energy integration. Comparable on technical energy consulting for industry, buildings, and municipalities, with a similar geographic footprint but a research-driven, not-for-profit operating model.
• Prognos AG: European research and consulting firm providing energy, climate, and economic studies for governments and enterprises. Comparable in energy consulting for public institutions and development banks, though substantially larger in headcount and project scale.
• Drees & Sommer: Large German engineering and consulting firm with a dedicated energy and sustainability practice serving real estate, industry, and public-sector clients. Comparable in delivering energy audits, energy concepts, and efficiency work, but operates at significantly greater scale and breadth across Germany and internationally.
• dena (Deutsche Energie-Agentur): Germany's central energy agency providing consulting, efficiency programs, and policy support for energy transition. Comparable in addressing energy efficiency mandates and municipal/industrial clients, though operating as a publicly-funded agency rather than a private consultancy.
• DEKRA Energy & Sustainability: International testing and certification organization with energy consulting services including audits, energy management systems, and efficiency advisory. Comparable on BAFA-listed audit services and European enterprise client base, operating at a much larger scale.
• TÜV SÜD Energy Consulting: Global testing, inspection, and certification group with an energy consulting division offering energy audits, ISO 50001 implementation, and efficiency services. Comparable in BAFA-listed audit delivery and German enterprise/municipal coverage, with substantially broader geographic and service reach.

Emerging players

• Öko-Institut: German independent research and consultancy working on energy efficiency, renewable energy, and climate policy for public-sector and EU clients. Comparable in delivering interdisciplinary energy consulting with a sustainability lens, though focused more on policy/research than implementation audits.

Direct peers

Comparable in its interdisciplinary energy consulting approach and mix of German domestic and international development work.
• EnergyConsult GmbH: Germany-based energy consulting firm offering energy audits, energy concepts, energy management, and efficiency services to industry, municipalities, and property managers. Highly comparable to Energie Consult in service mix, target customers, and German regional focus.
