Making Smart Energy Reduction in Non-Residential Buildings Easier

With the daunting task of transforming 480,000 non-residential buildings to achieve CO2 neutrality by 2050, as outlined in the Dutch Climate Agreement (2019), the need for better and more efficient data sharing is growing. Non-residential buildings need to share relevant data easily and securely with project partners and optimise the cost-effectiveness of CO2 reduction projects. 

The current market practice is prone to errors, with data often shared based on outdated or incorrect authorizations, presenting a significant challenge. The [DVU (Data Space for Energy Reduction in Non-Residential Buildings)](https://www.platformduurzamehuisvesting.nl) aims to address this challenge by eliminating data-sharing barriers in the current market. 

The DVU architecture leverages i4Trust and is set up as a federated data space, encompassing all standardised technical, operational, and legal agreements from the [iSHARE Trust Framework](http://framework.ishare.eu/). This supports the [WEii protocol](https://www.dgbc.nl/nieuws/versie-30-van-het-weii-protocol-live-6702) developed by the Dutch Green Building Council to create digital twins for developing cost-effective CO2 reduction projects with reliable business cases. 

DVU optimises interoperability with adjacent data spaces by adopting these open standards for data sharing, using the [iSHARE specifications](https://dev.ishare.eu/) for authentication and authorization.
