Was ist die HSG HUMMEL Service Group?

Die HSG HUMMEL Service Group ist die Dachorganisation von Frank Hummel mit Sitz in Frickenhausen bei Stuttgart. Sie umfasst drei Bereiche: Frank-Hummel-Consulting (strategische Beratung und Sparring für den Mittelstand), den Innovation HUB (Inkubator, Accelerator und Coworking) und REVOLUTION E (All-Electric Buildings mit Photovoltaik, Speicher, Wärmepumpen und Ladeinfrastruktur).

Wer ist Frank Hummel?

Frank Hummel ist Unternehmer mit über 30 Jahren Erfahrung. Er war 28 Jahre Geschäftsführer von HUMMEL Systemhaus (Elektrotechnik, 100+ Mitarbeitende) und hat das Unternehmen strategisch per Asset Deal an STRABAG/ZÜBLIN verkauft. Er ist zertifizierter Beirat (Beirat BW) und begleitet heute als Sparringspartner Geschäftsführer im Mittelstand bei strategischen Entscheidungen, Nachfolge und Energietransformation.

Was unterscheidet einen Sparringspartner von einem Berater?

Ein Sparringspartner kommt aus dem Unternehmertum, nicht aus der Beratung. Er begleitet Entscheidungen auf Augenhöhe, widerspricht wenn nötig und trägt Verantwortung mit. Im Gegensatz zum klassischen Berater, der Analysen und Empfehlungen liefert, erarbeitet ein Sparringspartner gemeinsam mit dem Unternehmer Lösungen und begleitet die Umsetzung.

Was ist REVOLUTION E?

REVOLUTION E ist die Marke der HSG für All-Electric Buildings. Das Leistungsspektrum umfasst Photovoltaik-Anlagen, Energiespeicher, Wärmepumpen und DC-Schnellladeinfrastruktur. Unter Frank Hummels Verantwortung werden jährlich 36 Mio. kWh Strom produziert – genug Energie für ca. 10.000 Haushalte.

Was ist der Innovation HUB in Frickenhausen?

Der Innovation HUB der HUMMEL Service Group ist Inkubator, Accelerator und Demonstrationsfläche auf 5.000 m² in Frickenhausen bei Stuttgart. Er bietet Coworking Spaces, einen Showroom für innovative Technologien, Veranstaltungsflächen und Büros zur Miete. Schwerpunktthemen sind Energietransformation, Elektromobilität und Digitalisierung.

From Cost Center to Energy Hub: The HUMMEL Innovation HUB Journey

Those who credibly exemplify transformation convince faster. In 2012, I implemented in my company building what I recommend today in the Quick-Check: create data, orchestrate technology, and align investments with profitability. Result: The location is evolving from a "consumption point" to an energy hub – with photovoltaics, intelligent ventilation/heating, and charging infrastructure as components of a system that pays off.

Video: Review & Learnings

Infrared heating meets the high expectations of entrepreneur and energy architect Frank Hummel – insights into the planning, execution, and operational advantages of the IR solution in my building.

Important note: I sold the former HUMMEL Systemhaus. Today, my activities are conducted through HSG GmbH & Co. KG (holding company). Operationally, I support companies manufacturer-independently with Frank-Hummel-Consulting (FHC) and REVOLUTION-E – from the Quick-Check to implementation with selected partners.

What the Video Shows – and Why It's Still Relevant Today

Fast Controllability & Zoning: demand-driven instead of continuous heating
Low Maintenance & Robust: no hydraulics, low service costs over the years
Comfort & Air Quality: stable indoor climate with decentralized ventilation (heat recovery)
Synergy with PV: 70 kWp self-generated power, fast reaction to PV peaks
Scalable in Existing Buildings: control, metering concept, storage, and DC charging in stages

Why This System Architecture?

1. IR in Offices – high reaction speed, zone control, very low maintenance.

2. Decentralized Ventilation – good air quality + heat recovery without complex duct networks.

3. PV as a Cash Lever – prioritize self-consumption; further optimize with storage and charging points.

4. AC/DC Charging – attractive for team, customers, and fleet; ideal for PV-driven charging.

5. Storage & Load Management – peak shaving (reducing power costs), shifting charging processes, utilizing PV surpluses.

Operational Insights (Summary)

Measurement & Metering Concept First: No reliable decisions without data
Orchestration Beats Individual Components: Control links heating/ventilation, PV, storage, charging
Reduced Maintenance Costs: IR + decentralized ventilation offer cost advantages over years
Roadmap Instead of Big Bang: In stages – Data → Quick Wins → Control → Storage → DC

The Shift to the INNOVATION HUB

From lived practice, the next step is logical: We are expanding the location into an INNOVATION HUB – a showcase & testbed for economic electrification.

What Visitors Experience

Live Data & Dashboards: Load profiles, PV, charging, possibly storage
Charging Infrastructure: 8× AC in operation, 2× DC planned – demonstrating peak shaving, PV shift, and load management
