We would like to recognize the extensive work that has been undertaken by all school boards over the past year to optimize and improve ventilation and filtration in schools. As a result of these efforts, we are pleased to note that ventilation improvement measures have been reported in all schools in all school boards across… Continue reading ON Ministry of Education: School Ventilation
Abstract A pilot study was performed to investigate whether the application of a new mechanical ventilation system with a fine F8 (MERV14) filter could improve indoor air quality in a high school near the Amsterdam ring road. PM10, PM2.5, and black carbon (BC) concentrations were measured continuously inside an occupied intervention classroom and outside the… Continue reading Wiley Online: The impact of particle filtration on indoor air quality in a classroom near a highway
This article presents the measurements of indoor climate in classrooms in the same school in Denmark. The classrooms had different ventilation systems: Ventilation was achieved either by manually operable windows, or by automatically operable windows with and without an exhaust fan in operation, or by a balanced mechanical ventilation system. Indoor air temperature and carbon… Continue reading REHVA: Indoor Air Quality and Thermal Environment in Classrooms with Different Ventilation Systems
