Abstract

There are still major concerns about the sharing and use of personal data, even though it has great value for society. This is particularly evident in the context of buildings, where data on citizens’ energy consumption offers great potential for optimization and resource conservation. However, building owners are reluctant to share their data due to concerns about control or misuse. Unlike business relationships in data ecosystems, where companies can establish technological trust mechanisms such as authorization and policy management, individuals require other parties to do so. The EU Data Governance Act proposes the use of neutral intermediaries called data trustees. However, the concrete design of data trustees for personal data remains open. To address this, we propose a prototype based on design science research methodology and data space technologies. The prototype demonstrates a data trustee for trusted sharing and use of personal data, with the added capability of leveraging decentralized service providers to offer value-added services, such as the generation of energy certificates. These decentralized services extend the functionality of the data trustee by providing adaptable, advanced solutions that benefit multiple stakeholders. In addition, the study contributes require-ments and lessons learned for future implementations.
