AIR FILTRATION ON HOSPITAL WARDS AND COVID
The use of air cleaning and disinfection HEPA filters to mitigate the transmission of the SARS-CoV-2 in hospitals is very topical, not least because institutions are being pressed into buying such systems for wards and classrooms etc. at a considerable cost. There is little hard evidence on how they work in real buildings so you may be interested in this talk at CATE 22 by Professor Clive Beggs of Leeds Beckett University. Working with teams at Queen Mary University of London and Addenbrookes Hospital, Cambridge, investigating how well they worked and found that room temperatures make a real difference.
DESIGNING AIR FLOWS TO MINIMISE COVID TRANSMISSION
Paul O’Sullivan from the University of Cork tackled the really important issue of how to design in natural ventilation to not only address comfort needs but also to reduce the risk of COVID transmission in spaces.

COVID, COMFORT AND VENTILATION IN HOSPITALS
Two amazing talks on the importance of being able to open windows in hospitals – even for short periods – to reduce pathogen loads indoors. Rod Escombe outlines his seminal work on the transmission of Tuberculosis in hospital wards in Peru and relates it to the purging of pathogens from doctor’s waiting rooms too, demonstrating how effective natural ventilation is in reducing cross-infections in medical settings: https://youtu.be/KrsCl3pWks4
REDUCING COVID DEATHS IN WARDS WITH A WINDOW OPENING REGIME
Stephanie J Dancer describes the how three hospitals in Lanarkshire in Scotland were studied in order to find ways to reduce cross infection in hospital wards. The work shows that opening windows in wards to purge the viral load had immediate and marked effects on reducing the number of deaths in wards: https://youtu.be/Wm_0Uxcs2vU
URBAN STRATEGIES FOR EXTREME HEATWAVES
David Sailor from Arizona talks about a range of strategies for keeping people thermally safe in the hottest US cities, based on his experiences in Arizona and California.

MODELLING THE IMPACT OF TREES ON COOLING LOADS IN BUILDINGS
Trees can reduce temperatures around buildings – so lowering cooling loads in them. Ulrike Passe from Iowa presents modelling research done in Iowa State University that now begins to quantify that effect and guide designers towards putting trees in optimal locations to maximise their impact on energy use both through natural ventilation pathways and by simply lowering the ambient temperatures around the buildings.
THE COOLING CRUNCH – USE FANS BEFORE HVAC – A HOW TO
Stefano Schiavon from UC Berkeley, California gave a fascinating talk on the fantastic potentials for fans for low energy cooling buildings. It comes with a link to a useful design tool for ceiling fans.

STANDARDS – WHOSE STANDARDS?
Philomena Bluyssen from TU Delft discusses how we have building regulations that specify indoor environmental quality (IEQ) standards that actually mean that staying indoors is not good for our health. We are confronted with diseases and disorders related to IEQ such as mental illnesses, obesity and illnesses that take longer to manifest, among which cardiovascular and chronic respiratory diseases and cancer, and very recently, COVID-19, caused by mainly airborne transmission of SARS-CoV-2 indoors, in spaces that comply with those standards.
Philomena Bluyssen asked at CATE 22 why are Building and Occupant-related Indicators overlooked while individual stressors are legislated for in excessive detail, and the complex interactions between them and their effects on – and between – occupants and the environment are ignored.

HUMANS AND BUILDINGS IN TIMES OF CLIMATE CHANGE
Hannah Pallubinsky a physiologist from the University of Maastricht discusses how we can Improve Comfort, Health, Satisfaction and Productivity of people in buildings – while reducing energy consumption, costs and emissions, in short design more Resilient Buildings?

ITS HOTTING UP: HOW MUCH AND HOW FAST?Alan Kennedy of Bristol University presents evidence from climate science about how hot can we expect it to get in the near and medium future with advice to designers that from now on we should be designing buildings that can tolerate summer temperatures of up to 450C
