Abstract: The Future Urban Ventilation Network (FUVN) is a collaborative research initiative in the UK dedicated to addressing the critical issue of managing exposure to air quality by considering airflow between indoor and outdoor environments. To facilitate well-informed decision-making in the pursuit of clean air, FUVN has established an Open Repository, currently in its beta version, accessible through the web-based portal at breathingcity.org (google.com). The repository currently has 40 datasets and 40 associated journal papers, serving as a valuable resource for researchers and stakeholders. The Open Repository contains high-quality datasets from field experiments, laboratory & physical modelling, and computational fluid dynamics (CFD) studies. Notably, it provides access to direct numerical simulation (DNS) data, which is often not readily available elsewhere. Users of the repository have multiple ways to search and access the datasets: they can filter them based on various criteria, explore a geographical map to visualize the data’s spatial distribution and access scientific articles related to the datasets in chronological order. We are committed to advancing this resource and plan to double the number of datasets in the coming year. Moreover, the network intends to publish a concise review paper summarizing the key findings and contributions of these datasets.
