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.

Archived Briefings from Protect Our Province BC
Join us for this discussion about how we are experiencing Carl Sagan's predicted "rejection of the enlightenment of science and return to superstition and darkness" - featuring these three remarkable physicians:
Dr. Lyne Filiatrault, Dr. Victor Leung and Dr. Julio Montaner.
Join us for an interview with Dr. Peter Rowe, Professor of Pediatrics and Director of the Children's Centre Chronic Fatigue Clinic at Johns Hopkins University as he gives us new hope for the treatment of Long COVID in Children. He explains that because of the parallels between ME/CFS and Long COVID in children, his 30 years of researched treatments for ME/CFS can be used to help children with Long COVID now while we are waiting for RCT ( randomized clinical trials) to occur.
Please join us for the POP BC live briefing on Long COVID: A Mass Disabling Event on Wednesday, October 30th at 1 pm as we discuss the important topic of Long COVID with Kayli Jamieson and Connie Chan, Long COVID survivors, and Dr. Ric Arseneau, Internal Medicine Specialist and Long COVID Physician and Director of one of the clinics treating Long COVID in BC.

Alberta Mom Photo: @BerlinBuyers My first confirmed Covid infection was in fall 2022 at a time when the few Covid protections we had left only applied to healthcare settings. 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
