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 dioxide (CO2) concentration, as well as opening of windows were continuously monitored for one month in the non-heating and heating seasons; measured CO2 concentration was used to estimate average classroom ventilation rates. The results show that mechanical ventilation and natural ventilation with automatically operable windows with exhaust fan performed notably better than the other systems. They indicate also that opening of windows was largely affected by customs and habits. Present results can be used as the basis for rational selection of systems that ensure adequate classroom ventilation.

REHVA: Indoor Air Quality and Thermal Environment in Classrooms with Different Ventilation Systems
Archived Briefings from Protect Our Province BC
As we start a new school year, clean air in schools is a vital issue not only because of the health effects from the ongoing COVID-19 pandemic and air pollution, but because of the direct link to the ability of children to learn. Hear about the new recommendations for Indoor Air Quality in Schools and Childcare Facilities from Vancouver Coastal Health and Fraser Health.
“For some of the most vulnerable patients, the air in the hospital can be deadlier than the diagnosis that brought them in”
Join Protect our Province BC and Drs. Susan Lee, Jean Warneboldt, and Victor Leung to hear about their advocacy, their struggles and successes in improving the air quality in different BC Health Authorities. Why are different healthcare administrations within BC treating this critical topic so differently - in one, obstructing and blocking and in another rewarding and awarding?
In honor of February being Heart Month, cardiologist Dr. Leslie Kasza joined Protect our Province BC’s Dr. Susan Kuo for a discussion on COVID-19’s impact on heart health and how you can reduce your risk. Don’t be fooled into thinking it won’t happen to you because you are _________, fill in the blank: young, healthy vaccinated and/or you only had a mild infection, etc.

I knew I was at higher risk of developing Long Covid as I am a working age woman. This terrified me as my son had already had… Continue reading No One is Listening to Me
