Energiedienste aller Art

What Energiedienste aller Art does

Energiedienste aller Art is a sole-proprietorship engineering and consulting office (Projekt- und Ingenieurbüro) headquartered in Dortmund, Germany, operating since at least 2016 with website content through December 2025. The firm, owned and represented by Ing. Abdel Hakim Barhoumi, delivers a broad portfolio of energy and environmental services organized into four tracks: Beratung (energy consulting, BAFA Vor-Ort-Beratung, audits under DIN 16247-1, non-residential certification under DIN V 18599), Konzepte (energy concepts, ventilation concepts under DIN 1946-6, climate protection concepts, feasibility studies), Beauftragung (outsourced energy/environmental/waste/incident/immission/water management officer roles, thermography, hydraulic balancing, Energieausweis, GEG/EnEV certification), and Erneuerbare Energien (photovoltaics, solar thermal, heat pumps, micro-CHP, biomass, district heating, hydrogen/fuel cells, Power-to-Gas, storage technology). Services are billed either on a fixed-price or time-and-materials basis under HOAI fee rules, with VAT charged separately and a 30-day payment term.

The business is credentialed as a KfW Sachverständiger, BAfA energy advisor, dena-listed Energieeffizienz-Experte, and state-certified Sachverständige für Schall und Wärmeschutz, and holds DEKRA ISO 14001 and ISO 50001 certifications. These credentials allow the firm to broker access to federal subsidies (KfW 151/276/433 and BAfA 'Heizen mit EE'), prepare and verify applications, and act as commissioning officer for compliance mandates. Customers are exclusively SMBs, private households, and municipalities/Stadtwerke in the North Rhine-Westphalia region, with revenue distributed across many small project-based engagements rather than concentrated in enterprise contracts. The go-to-market is sales-led through direct consulting engagements, supported by a professional website, Google Business Profile, and a long-form content engine across YouTube, Xing, LinkedIn, Facebook, and Twitter/X; word-of-mouth referrals are an explicit acquisition channel.

Scale indicators2 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• 1Komma5° GmbH: Fast-growing German energy startup installing heat pumps, PV, and storage with integrated energy consulting (Wärmepumpenplanung, Energiekonzepte, subsidy application) — directly comparable service overlap in residential heat-pump/HVAC consulting with subsidy handling, but at venture-backed national scale.
• Enerix Franchise GmbH: German franchise network of local Energieberater and PV/heat-pump installers that combines on-site energy consulting, Energiekonzepte, and subsidy handling with a scalable brand — comparable scope of residential energy consulting plus renewable planning, with a distributed/regional delivery model similar in spirit to Energiedienste's local focus.

Broad incumbents

• Drees & Sommer: Large German engineering consultancy with a dedicated energy, sustainability, and building-certification practice (ESG, Energieausweis, KfW/dena experts) serving commercial, industrial, and municipal clients — comparable in service breadth but orders of magnitude larger in scale and geography.
• Vaillant Deutschland: Leading German HVAC manufacturer with heating, heat-pump, and ventilation products supported by Vaillant's 'Fachpartner' network that performs Energieberatung, Energiekonzepte, and subsidy application — comparable in residential energy and HVAC consulting scope, but as part of a global manufacturing incumbent.
• Viessmann Climate Solutions: Major German HVAC manufacturer (heat pumps, boilers, CHP, fuel cells) that also runs Viessmann Niederlassungen and partner networks offering Energieberatung, system planning, and KfW/BAfA application support — comparable in residential energy-system planning but a global incumbent on the product side.
• TÜV Rheinland Energie und Umwelt: Major German testing, inspection, and certification body offering energy audits, ISO 50001/14001 management system certification, Energieberatung, and Energieausweis services — comparable in regulatory/energy advisory services but operating as a global incumbent.
• DEKRA Certification: Provides ISO 14001, ISO 50001, and energy management certification plus Energieberatung and Energieausweis services in Germany; the same firm that issues the certifications held by Energiedienste aller Art, and itself operates a competing energy-services portfolio.

Others

• GIH Gebäudeenergieberater Ingenieure Handwerker e.V. National association of certified Energieberater (engineers, architects, tradespeople) in Germany that maintains the GIH energy-expert list and connects customers to local Beratung — directly comparable expert credentialing framework and customer-referral channel for Energieberater firms like Energiedienste.
• co2online GmbH: Non-profit energy consulting and consumer information platform funded by the German federal government and the EU, providing Energieberatung, subsidy guidance, and modernization tools — addresses the same end customers but as a free, public-interest service rather than a paid Ingenieurbüro.

Direct peers

• Verbraucherzentrale NRW Energieberatung: Public-sector Energieberatung serving NRW consumers with subsidized one-on-one consulting, including Energieausweis, GEG/EnEV advice, and KfW/BAfA application support — the same residential/SMB customer base and service mix as Energiedienste aller Art, but at a state-subsidized flat fee.
