Renz Solutions

What Renz Solutions does

Renz Solutions GmbH is an owner-managed German Mittelstand engineering company founded in 1981 (firmographic) / 1983 (company history) by Jochen C. Renz, headquartered in Aidlingen with manufacturing in Ehningen and a showroom in Düsseldorf. The company designs, manufactures, and installs integral building interior systems for commercial real estate, combining acoustics, lighting, climate, walls, ceilings, and building automation into a unified proprietary ecosystem. Core proprietary products include the Renz Integraldecke (an aluminum ceiling profile that attaches walls directly to the concrete slab and integrates electrical, LAN, and cooling lines), the Klima-Komfort-Modul (a 10-function all-in-one climate module with claimed 100 W cooling from 10 W input), the Quellluftsystem source-air distribution, glass acoustic partition walls, broadband acoustic absorbers, LED Lightline luminaires, and a Modbus/KNX-based room automation system co-developed with Wago.

Renz sells directly to enterprise customers in Germany and selected European markets (Austria, Switzerland, Belgium) through a regional field-sales organization structured by German federal states, supported by technical advisors, architects, and engineers. The revenue model combines three streams: consulting and planning services (needs analysis, potential analysis, change-management advisory, concept development, economic viability analysis), proprietary hardware sales (in-house manufactured acoustic, lighting, climate, wall, and ceiling products), and turnkey implementation delivered by internal project teams. Named customers span blue-chip enterprises across finance (Deutsche Bank, UBS, Zürich Versicherung, Axa), automotive (Audi, BMW, Mercedes-Benz), chemicals/pharma (BASF, Fresenius), energy (E.ON, RWE), technology (Siemens, Infineon), telecom (Deutsche Post, T-Mobile), media (ProSieben Sat.1), and the public sector (Bundesministerium für Finanzen, Stadtwerke Essen, Universität Freiburg). Pricing is custom-quoted per project with multi-year contracts.

The company is part of the Renz Unternehmensgruppe and operates its own research center (Institut LAB / Forschungszentrum). Strategic technology partners include Schneider Electric (KNX building automation, joint brochure), Wago (room automation control unit), and Fraunhofer Gesellschaft (research collaboration). Renz has been awarded the Top 100 Innovationspreis in six consecutive selection cycles (2016, 2018, 2020, 2022, 2024, 2025), the TOP Consulting Award in 2020, and an AIT Innovation special recognition at BAU 2019.

Core offering

Renz Solutions is a German consulting, planning, and development company for real estate that designs, manufactures, and installs an integral system of proprietary commercial interior building products covering acoustics, climate, lighting, walls, ceilings, and room automation. The company delivers end-to-end project services from needs and potential analysis through concept development, economic viability analysis, and turnkey implementation, supported by its own research center (Institut LAB) and in-house production facility in Ehningen. Its product portfolio includes the Akustikprogramm, Lichtprogramm, Klimaprogramm (Klima-Komfort-Modul and Quellluftsystem), Wandprogramm, Silent Rooms, the Renz Integraldecke ceiling system, and Raumautomation.

Product overview

Renz Solutions offers an integral system of building and workspace solutions organized into six interlocking product programs: the Akustikprogramm (acoustic products including broadband compact absorbers BKA-I and BKA, composite panel resonators VPR, acoustic wall art, ceiling sails, and glass acoustic partition systems); the Lichtprogramm (LED lighting including floor lamps, wall/acoustic shield luminaires, pendant luminaires, and Renz projector technology across multiple Lightline model sizes); the Klimaprogramm (climate systems centered on the Klima-Komfort-Modul/KKM — an All-in-One module combining 10 functions for cooling, heating, dehumidification, air purification, and disinfection — and the Quellluftsystem for draught-free source air distribution); the Wandprogramm (wall systems including the Profilsysteme Renz 2000, Renz 35/2, Renz Construct, and Renz Glas-Akustik, plus Türsysteme such as aluminum frame doors, glass doors, solid wood doors, and sliding doors, and integrated Elektrifizierung); Silent Rooms (prefabricated acoustic focus rooms for open-plan environments); and the Deckensystem (Renz Integraldecke — an aluminum profile ceiling system that attaches walls directly to the concrete slab for superior stability and integrates multiple trades). These products are supported by a proprietary Raumautomation (MSR) system using Modbus protocol and web-browser access for integrated control of lighting, climate, and shading. Renz Solutions differentiates through integral design — combining acoustic, lighting, climate, automation, and structural systems into a unified, energy-efficient building approach.
