Urban and building ventilation datasets
Datasets on how air is exchanged between streets, courtyards, buildings and the flow above them: ventilation and air-exchange rates for street canyons, natural and cross-ventilation of buildings, and flow through openings. They come from wind tunnels, water flumes and field campaigns, alongside LES and RANS studies of canopy ventilation.
