The Adler Group, in cooperation with PAUL Tech AG, has agreed a long-term framework agreement for the transformation of the heat supply for its Berlin building portfolio. This project involves the decarbonisation of approximately 17,500 residential and commercial units in the capital. The implementation of the measures is scheduled to begin in summer 2026.
Legal advice during the contract negotiations was provided by Luther Rechtsanwaltsgesellschaft mbH. The law firm advised the Adler Group comprehensively on financing law, public law, real estate law, and energy law aspects of the complex contractual framework. This integrated legal advice underscored the importance of interdisciplinary expertise for such projects in the real estate sector.
Technological Basis and Strategic Importance
The PAUL Net Zero technology platform will be used for the conversion. This system combines heat pump systems with AI-supported energy optimisation, as well as intelligent control and monitoring systems. The decision for this technology is part of a strategy to modernise and reduce the CO2 footprint of the Adler Group's real estate portfolio. Jannik Heß, Chief Executive Officer of the Adler Group, highlighted that the interdisciplinary expertise of the consultants involved was of great importance for the successful conclusion of the contract and contributed to the efficient merging of complex legal and economic requirements.
Advice from a specialised Luther team, led by Dr. Holger Stappert, covered the multifaceted legal and economic questions associated with structuring and concluding such a project. This illustrates the increasing need for comprehensive legal expertise when implementing the heat transition in large property portfolios. For owners of existing properties, scalable models for decarbonisation are becoming increasingly important.
Background and Implications for the Real Estate Sector
This transaction reflects the growing relevance of integrated legal advice in projects for transforming energy supply in the building sector. Such initiatives are increasingly relevant due to regulatory requirements, rising CO2 costs, and the strategic necessity of long-term economic viability of heat supply. The decarbonisation of real estate portfolios is thus becoming a decisive factor for the future viability and value of existing properties. The cooperation between Adler Group and PAUL Tech AG is an example of real estate companies proactively aligning with these developments.
