The DVU (Data Space for Energy Reduction in Non-Residential Buildings) initiative addresses the need for secure and efficient data sharing in the pursuit of optimising CO2-reduction projects within non-residential buildings. By facilitating the exchange of relevant energy consumption data among stakeholders, DVU aims to drive innovation and sustainable practices in the construction and building management sectors.

Challenge and Context

Non-residential building owners face significant challenges in sharing crucial data with project partners to enhance CO2-reduction initiatives. Traditional energy labels often fail to accurately correlate with real-world energy consumption, delaying the development of ambitious CO2-reduction projects. Complete and up-to-date data on measured energy consumption, combined with key construction features, is essential for creating digital twins and optimising CO2-reduction strategies effectively.


DVU offers a comprehensive solution to overcome data-sharing barriers in the market. By supporting WEii protocol developed by the Dutch Green Building Council, DVU enables Data Service Consumers to access and utilise data on measured energy consumption for modelling CO2-reduction scenarios. These digital twins serve as valuable tools for developing cost-effective CO2-reduction projects with reliable business cases.

How it works

DVU operates as a federated data space leveraging the iSHARE Trust Framework to ensure secure data sharing for energy. Through a user-friendly interface provided by the Netherlands Enterprise Agency, Entitled Parties initiate data-sharing requests with Data Service Consumers. Identification and authentication are facilitated by eHerkenning Identity Provider, ensuring the legitimacy of data transactions. Upon successful authorisations, data sharing occurs between Data Service Providers and Consumers, Supporting various types of data services.

Added Value Through the iSHARE Trust Framework

The Trust Framework does not just establish a standard for identification, authentication and authorization, but also enables individual data owners to choose to share their data and within reasonable limits. The usage policies and incorporation of a hyperledger based participant registry improves trustworthiness among the participants and allows for efficient scaling up of the solution. It further enables legal safeguards on access and usage of data.
