In a systematic review of over 200 scientific studies, the German research institute, Fraunhofer Institute for Building Physics IBP, have found that many European schools are unable to provide pupils with a proper indoor environment for learning. Too many schools fail to provide a sufficient outdoor air supply rate and are too warm in the summer months.
This Applications Manual provides guidance on natural ventilation that is strategically important to architects, building services engineers, clients and their advisors.
