MODERATE aims to connect data providers with other building stakeholders by improving interoperability between datasets, by making use of data from different providers. In addition, the research project aims to develop services based on data analytics that can transform raw data into knowledge for end-users. Lack of interoperability between building datasets is a key issue MODERATE will address by developing an open marketplace where data can be reliably shared between data owners. In a next step, the platform will allow for users to make use of different services to analyse the available data, gain insights on the building stock and create a long-term impact for the management of buildings. A key aspect of the platform to increase trust for providers to share the data they own, is the use of synthetic data generation techniques, which are not widely applied in the building sector yet. These techniques protect the most sensitive data similar to classical anonymization and keep 80-90% of the most valuable parts to allow for insightful data analytics.
