In recent years, the 'usability' of ventilation and air infiltration models (both public domain and commercially available) has increased greatly. Possible areas of application for 15 such models are identified in this report. (These are mainly 'network' models.) In addition, it discusses the input data that must be provided in order to use them. The capabilities of the models are described and full contact details on how to obtain them are provided.
