DVU

Introduction

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. DVU aims to facilitate the exchange of relevant energy consumption data among stakeholders, driving 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.

Solution

DVU offers a comprehensive solution to overcome data-sharing barriers in the market. DVU supports the WEii protocol developed by the Dutch Green Building Council. This enables Data Service Consumers to access and utilize 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. eHerkenning facilitates the identification and authentication process, ensuring the legitimacy of data transactions. Upon successful authorizations, 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 sets the standard for identification, authentication, and authorization, enabling individual data owners to share their data within reasonable limits. The usage policies and incorporation of a hyperledger-based participant registry improve trustworthiness among the participants. This enables efficient scaling of the solution while providing legal safeguards for data access and usage.
