期刊介绍： This is a peer reviewed journal aimed at providing the latest information on research and application. Topics include: • New ideas concerned with the development or application of ventilation; • Validated case studies demonstrating the performance of ventilation strategies; • Information on needs and solutions for specific building types including: offices, dwellings, schools, hospitals, parking garages, urban buildings and recreational buildings etc; • Developments in numerical methods; • Measurement techniques; • Related issues in which the impact of ventilation plays an important role (e.g. the interaction of ventilation with air quality, health and comfort); • Energy issues related to ventilation (e.g. low energy systems, ventilation heating and cooling loss); • Driving forces (weather data, fan performance etc).
