Environmental Responsibility

As a leading real estate service provider, Techem helps property owners, housing companies, and residents use energy more efficiently. This can help optimize energy consumption and lay the groundwork for reducing emissions from building operations.

Environmental responsibility at Techem 

In its own environmental operations, Techem focuses on reducing CO₂e emissions and increasing energy efficiency. In addition, we implement measures in our own operations to conserve resources throughout the value chain.

For our customers, we rely on our digital solutions for buildings, which provide transparency into energy consumption, can optimize heating systems, and support the transition to renewable energy. As part of the mobility transition, we also make an important contribution through our EV charging services. We offer our customers a 360-degree package ranging from planning and installation to power supply.

Measures and targets

The transformation of the building sector is a key driver of climate action. To this end, we are focusing on ongoing automation. A key milestone was reached in fiscal year 2025: More than 85% of our measuring devices are already wireless-enabled. The digital infrastructure forms the foundation for automated consumption data, data-driven energy optimization, and the decarbonization of buildings.

Climate neutrality is a long-term goal that guides our efforts. The decarbonization roadmap calls for reducing Group-wide emissions across all scopes by at least 90% compared to 2020. As early as fiscal year 2025, the CO₂e footprint was reduced by approximately 27% compared to the base year. In addition, Techem emphasizes energy management in accordance with ISO 50001, energy audits, and the expansion of renewable energy in its own operations.

Techem is working to use resources efficiently throughout the entire product life cycle. This includes extending the service life of equipment, reuse, recycling, and life cycle analyses. In fiscal year 2025, a reuse center was established in collaboration with an external partner. There, used equipment is inspected for reusability and—if suitable—put back into service. This saves resources, reduces waste, and extends the useful life of products.

Techem Research Institute on Sustainability (TRIOS)

The Techem Research Institute on Sustainability (TRIOS) is responsible for Techem’s research, analysis, and implementation capabilities in the areas of consumption transparency, energy efficiency, greenhouse gas emissions, and CO₂e reduction. To advance climate and environmental protection consistently throughout the company and leverage synergies for the development of innovative market solutions, TRIOS calculates the corporate CO₂e footprint, develops and monitors the decarbonization plan, and contributes to publications and research aimed at improving energy efficiency and decarbonizing the building stock.

Techem Atlas for Energy, Heat & Water

A central pillar of TRIOS' scientific contributions is the Atlas for Energy, Heat & Water (formerly the Consumption Characteristics Study), which we publish annually. The study is based on adjusted data on energy and water consumption and the associated costs of around 1.2 million apartments in Germany in more than 110,000 residential buildings.
