Products and solutions for sustainable development
As a digitalization guide for the housing industry, Minol offers smart, ESG-compliant solutions for climate-friendly property management. With over 70 years of experience, we support you in implementing the energy transition – from intelligent consumption monitoring and electromobility to sustainable real estate. Together, we are shaping the climate-neutral property of tomorrow.
The Minol-ZENNER Group connects industries, sectors, and technologies. Together with our customers and partners, we develop solutions for the digitalization of the energy transition in the areas of smart metering and submetering, smart grid, smart mobility, and smart city. Minol Messtechnik W. Lehmann GmbH & Co. KG is a digitalization guide and partner for a sustainable real estate industry. Thanks to decades of experience and a strong spirit of innovation, we have developed solutions to make buildings digital, intelligent, and energy-efficient. In doing so, we support the goal of making the building stock climate-neutral by 2050.
ZENNER International GmbH & Co. KG is a leading provider of measurement technology, sensors, and digital solutions, supporting municipal utilities and energy suppliers in the digitalization of the energy transition. With a broad portfolio of Internet of Things ( IoT) solutions , ZENNER, together with its customers and a network of partners, implements a wide range of innovative applications for digital consumption monitoring, intelligent buildings, and smart cities and communities. ZENNER's solutions enable processes to be designed in an energy-efficient, sustainable, and climate-friendly manner.
Together, the companies of the Minol-ZENNER Group offer a broad range of solutions for all aspects of the energy transition. From consumption monitoring and the building sector to smart grids, neighborhoods, and smart cities.
“As a manufacturer of measuring instruments, we have been supplying water and energy providers with reliable technology for consumption monitoring since 1903. For over 100 years, we have thus supported the responsible use of resources. Today, more than ever, sustainability and climate protection require transparency and therefore digital solutions – also to implement regulations such as the Heating Costs Ordinance (HKVO), the EU Taxonomy, or the goals of the National Drinking Water Strategy and the energy transition in Germany. We move with the times and always focus on developing future-proof and sustainable solutions, which we develop in dialogue with our customers.”

Smart metering and submetering
Achieving climate neutrality will pose a significant challenge for existing buildings. Many properties will soon require modernization, as owners and managers will be required to use remotely readable metering technology. This is stipulated by the Heating Costs Ordinance (HKVO), which was amended in December 2021. This implements the requirements of the EU Energy Efficiency Directive (EED) into national law. The goal is to achieve sustainability and make the building stock climate-neutral by 2045.
This requires a suitable infrastructure, which we as a group provide: wireless metering technology, energy-efficient communication networks, BSI-compliant data services, and a wide range of solutions for monitoring and billing energy consumption. The resulting transparency sustainably reduces energy consumption and costs and significantly lowers CO₂ emissions – both at the apartment level ( submetering ) and at the building level ( smart metering ). Our technical solutions enable the future-proof digitalization of metering points and the integration of submetering and smart metering. This generates data that makes the overall energy consumption of buildings transparent and allows for targeted optimization.
Smart Mobility Projects
The number of electric vehicles on our roads is growing. The German government's goal is to have seven to ten million electric vehicles registered in Germany by 2030. Charging infrastructure , both private and public, plays a crucial role in the success of e-mobility. Therefore, one million charging points are to be installed by 2030. Efficient load and energy management is also essential to prevent grid overload. Network operators will therefore have the right to temporarily limit the charging power of electric vehicles. This requires a BSI-compliant communication infrastructure with data transmission via the smart meter gateway.
Today, our group of companies already has a market-ready solution that meets all these requirements. Smartly networked charging stations and parking spaces, secure data transmission, grid-friendly control, and sophisticated data analysis capabilities – in the field of e-mobility, we intelligently integrate the various components. We are also affiliated with GP JOULE , a leading provider of electric and hydrogen mobility projects.
To implement the energy transition, digital solutions are needed for the effective use of smart metering systems (iMSys). This applies particularly to data acquisition and transmission in the areas of submetering, electromobility, and energy management. To provide services related to these topics, we utilize the ISO 27001 certified platform of ZENNER Connect GmbH . This gives us a secure, legally compliant, and BSI-compliant infrastructure for digital data communication . With the "Switching" function, distribution network operators and direct marketers have access to a field-proven and integrated solution for measurement, switching, and control tasks in the smart grid.
For network operators, metering point operators, direct marketers and municipal utilities, we offer solutions for the efficient use of the future digital energy infrastructure.
Global CO2 emissions can be significantly reduced through electricity generation using photovoltaics . Together with our partner, we offer innovative concepts for municipal utilities, neighborhoods, and properties. For example, in tenant electricity models, electricity is generated using photovoltaic systems on the roof and consumed by the residents of the property or neighborhood. The amended Renewable Energy Sources Act (EEG), passed in December 2020, provides the legal framework for this. We also offer a complete package for tenant electricity. This includes all services, from analyzing the roof area and installing the PV systems and metering technology to billing.
Smart City
Municipalities, public utilities, and companies within the municipal network need solutions that make life in cities and communities more sustainable and improve the quality of life. Digitalization offers a major opportunity and is the key enabler. The possibilities range from applications such as smart water , smart waste , CO2 traffic lights, and intelligent weather stations to comprehensive solutions for smart buildings and neighborhoods. Electromobility and renewable energies are also included. Many of our solutions are highly customized and precisely tailored to the specific requirements of each client. At the same time, they can be implemented globally and share a common goal: they contribute to many of the 17 Sustainable Development Goals set by the United Nations. Many municipalities have already taken the first steps toward becoming smart cities .
“To transform smart cities into sustainable cities, we need digital infrastructure and an interdisciplinary approach. This isn't just about connecting sensors, but also about connecting sectors. We understand smart cities as a cross-cutting concept, encompassing all topics and sectors. With each solution, the degree of digitalization and sustainability increases hand in hand. This directly contributes to the 17 Sustainable Development Goals of the United Nations. Every city needs its own individual vision that reflects its specific needs. Only in this way can individual digital solutions deliver added value for everyone.”
