#Covid19 High risk (yellow) zone at temperatures 5-11°C (spring & autumn)
An urgent public health message about clean indoor air & #ventilation (not fines & roadblocks) can have immediate impact on virus spread & prevent cases
WHO: ‘we are very concerned about rise in cases in Europe as it heads into winter’
‘Colder weather leads to behaviours that favour transmission of a respiratory virus- people tend to crowd indoors to stay warm, more often in poorly ventilated spaces’ smh.com.au/politics/feder…
‘overwhelming evidence that *inhalation* represents a major transmission route’
‘we urge public health officials to add clear guidance about importance of moving activities outdoors, improving indoor air & improving protection for high-risk workers’ science.sciencemag.org/content/early/…
Germany’s top doctor: ‘Most people only pass it to one person.. But occasionally, someone spreads it widely, creating a cluster of infections that drives the pandemic’
#Level 5 has no plan to prevent super-spread clusters in ~known~ high-risk conditions (crowds, indoors,poor ventilation) such as happening in overcrowded homes & schools, nursing/care homes, meat/food plants, or risk mitigation in shops, offices, cars, buses/trains/planes)
‘After 9 months of epidemiological data, we know that this is an overdispersed pathogen, meaning that it *tends to spread in clusters* but this knowledge has not yet fully entered our way of thinking about the pandemic—or our preventive practices’ theatlantic.com/health/archive…
#Covid19 has meant hard choices & serious consequences, with an escalation in restrictions and enforcement.
..but ‘crowded indoor spaces have been shown to be associated with increased transmission.. determining what is due to proximity & poor hygiene practices, & what is ~due to poor ventilation~ though, is difficult’
^so, risk of spread due to poor ventilation is accepted by HPSC 2/
..but, no rules from HSPC, just ‘suggestions, specifically for commercial & public buildings’ ..& only for mech ventilation, which is small % of all buildings ..but ‘residential & healthcare settings fall outside the scope of HPSC document’ ..& very limited advice for schools 3/
Explainer: Why the changes to Irish fire regs for ‘open-plan flats’ put lives at risk
(could be a long thread, please bear with me, this is ~most critically important~ issue for discussions about our future housing, & it’s not getting any attention 1/
video is a recent rescue in Los Angeles, from 6th floor balcony of 25 storey building, in daylight, attended by 20 fire-trucks & rescue helicopter, in a fire-sprinklered & regulated building; 7 people & a baby injured, 10 homes burnt
(this is all important later in the thread) 2/
Typical 2-bedroom flat before reg changes;
note- balcony, hall separating kitchen from bedrooms, direct escape from bedrooms (not through kitchen), opening windows; + short main corridors with escape stairs every 6ish flats (kitchen, esp oil fire is a high-fire risk area) 3/
[Thread] Better than sprawl, better than high rise. Housing communities that are sustainable, affordable & beautiful places to live.
Norwich, UK. Award winning, low energy, low build cost, high density social housing 1/
Mid-rise, high-density housing in the Netherlands with safe streets, places to sit, spaces to play, priority for walking & cycling 2/
Cycle lanes in Copenhagen, city circulation without congestion through incremental low-cost investment in cycling infrastructure
Building heights (again)..
here’s an example of how Planners consider building heights. First by looking at existing buildings 1/ (Liberties Dublin, Local Area Plan)
& taking account of broader issues... ‘high rise residential development is market driven & relies upon sufficient numbers of purchasers prepared to pay a premium’ 2/
& looking in great detail at the impact, both on the immediate area & on the city (looking in & looking out) 3/
