Play on AI "The phrase ' giraffes can't talk because they have no vocal folds but can dance" is a playful contradiction that highlights the importance of embracing individuality and self expression, even if it means defying expectations or stereotypes. It suggests that while giraffes may not have the physical structures to produce human speech they can still communicate and express themselves through other means like dancing. Which is a way of expressing their unique selves and finding their own rhythm '

However, “a low level of CO2 doesn’t necessarily mean that your ventilation is good,” cautioned Dr Chris Iddon, chair of the CIBSE natural ventilation group. This is due to the time it takes for CO2 to build up in a space, which will vary according to room size and the number of occupants, he explained. Iddon also pointed out that there is still a lot we don’t know about Covid-19, including the dose of virus required to infect someone. In addition, the amount of aerosols that someone might release can vary by several orders of magnitude, he said. CISBE’s current guidance on ventilation in the context of Covid-19 recommends “ventilating spaces as much as reasonably possible with outside air as one measure to reduce transmission risk.” It also states that, “CO2 concentrations regularly greater than 1500 ppm are indicative of poorly ventilated spaces.” This advice is consistent with that of the UK government’s environmental and modelling group, part of SAGE (Scientific Advisory Group for Emergencies), published in October.
Simply opening the windows five minutes every hour doesn’t work, said Jimenez. One way of mitigating the risk of transmission is to equip schools with CO2 monitors, to measure CO2 as a proxy for ventilation and for the amount of virus in the room, said Wenger. CO2 monitors with a traffic light system, which are equipped with non-dispersive infrared (NDIR) sensors, are cost-effective and can help remind teachers to act by opening windows when levels get too high (usually above 800-1,000 ppm), said Wenger. Jimenez agreed that CO2 sensors are essential but recommended keeping the CO2 level “below 700 ppm at all times”.
The impact of architects’ decisions on the environment has been a constant consideration throughout Thoua’s career. “I think a lot of architects have the sense that, in order to build something, you have to destroy something else. So you have to tread very lightly,” she said. “Indoor air quality and the indoor environment play a significant role on children’s health, development, academic performance, concentration and memory. Different studies have shown again and again how important it is to maintain good indoor air quality and a good environment in schools, and it is a matter of social justice as well,” she said, stressing that, as designers, “we have to make sure we get it right”
The research, conducted in four classrooms in each of the six schools over one year, included monitoring CO2 levels as a proxy for ventilation rates and air quality, measuring humidity and temperature levels, observing blind usage and window opening behaviour, as well as assessing teachers’ and children’s perceptions of their environment, such as satisfaction, through questionnaires. One of the researchers involved in this program was Chryssa Thoua, an architect who is currently completing her PhD at University College London in collaboration with Architype on a different project. The results were clear. Passive-standard schools performed better across all the measurements. “Temperatures were more stable in the more recent passive house schools, and ventilation rates were higher in the passive house schools,” said Thoua.
While we don’t yet have published studies on the impact of passive house design on Covid-19 transmission, the need for good ventilation is well-established in the scientific literature, & in policy advice relating to Covid-19. Jimenez, who is studying the transmission of Covid-19, is one of the authors of a recent study which highlights how singing indoors, unmasked, can spread Covid-19... several super spreading events involving SARS-CoV-2, the virus that causes Covid-19, have occurred during choir practices. Such events highlight the importance of following public health advice.. the use of face coverings, hand washing & social distancing... tell us something about how the disease can be transmitted. Scientific research on Covid-19 is moving at a very fast pace...our understanding of this new disease is constantly evolving...However, Jimenez told Passive House Plus, the evidence for airborne (through the air) transmission of Covid-19 is now “overwhelming, & it has been overwhelming for quite some time.” “When people talk, aerosols are between 100 & 2,000 times more important than droplets. There are two situations in which the disease is transmitted: one is when you talk in close proximity to someone .... The second situation... when you share indoor air in a room with someone who’s infected for a long time, meaning at least 30 minutes, to an hour or several hours.....see these super spreading events,”...Jimenez is one of 36 scientists who wrote an open letter to the WHO in July, asking it to recognise the airborne spread of Covid-19, & to revise its recommendations. The letter is signed by 239 scientists..published in the journal Clinical Infectious Diseases. It cautions against overcrowding & calls for ventilation... Another signatory is Professor John Wenger from University College Cork...“Aerosol or airborne transmission is really an important way that the virus is spread.. it’s been kind of ignored” Graph CO2 levels schools data ARCHITYPE ARCHITECTS shown

Excerpt from blog @petermbenglish At height of pandemic "More emphasis on ventilation CO2 monitors should be routine in workplaces and in any in which CO2 levels exceed a safe level...should be immediately evacuated. Schools should encourage staff and pupils to wear clothing suitable for working in cold conditions ( some schools have used school uniform regulations to ban coats etc requiring inadequate ventilation instead and thus increase the risk to pupils, staff and their contacts)
