REHVA Journal article, April issue: “Ventilation and a Healthy and Comfortable Indoor Environment – What is the rationale behind the requirements?”
“Given the increasing airtightness of buildings, occupants have to more and more on their ventilation systems to ensure a comfortable and healthy indoor air quality. We trust that ventilation standards address this concern. However, significant disparities exist between countries regarding the requirements and regulations for ventilating various spaces, including dwellings, offices, and classrooms. In fact, the variation in prescribed minimum ventilation flowrates for similar building types among different countries can exceed a factor of five.”
