\u201cBy the 2050s, median outdoor temperatures in Sydney’s hotter inland areas could rise by up to 5\u00b0C under high-emissions climate scenarios, with\u202fhot days\u202fbecoming longer and more frequent,\u201d said Dr Jingjing Liu from the School of Architecture, Design and Planning. \u202f<\/p>\n
Under these conditions:<\/p>\n
During extreme heat events,\u202funder the high-emission scenario,\u202findoor temperatures could remain above 30\u00b0C for several consecutive days.<\/p>\n
The findings have significant implications for public health, especially during prolonged heatwaves and potential power outages.<\/p>\n
“In a future heatwave combined with a blackout, many apartments simply won’t be able to keep residents safe,” said\u202fDr Haddad.<\/p>\n
Heat stress is an increasingly\u202fimportant issue\u202ffor the health and well-being of populations exposed to\u202fhigh temperatures\u202fand humidity.\u202f<\/p>\n
“People often assume air conditioning\u202f(AC)\u202fwill solve the problem, but not everyone can afford to\u202finstall or run\u202fair conditioning\u202fdue to cooling poverty, and during power outages, it may not be available.\u202f<\/p>\n
\u201cAlso,\u202fwhile AC can provide relief against heat stress,\u202fwidespread use of AC can\u202fadd\u202fpressure on electricity systems and even more heat to our cities,\u201d\u202fsaid\u202fDr Haddad.<\/p>\n
Older people, low-income households,\u202frenters\u202fand people with chronic health conditions are expected to be among those most vulnerable.<\/p>\n
The research argues\u202fthat Australia’s building regulations should move beyond measuring energy efficiency based on historical weather data and instead assess a building’s “passive survivability”\u202f-\u202fits ability to\u202fmaintain\u202fsafe indoor temperatures during extreme heat without relying on air conditioning.<\/p>\n
Passive building strategies, including cool roofs, natural ventilation, and shading have proven to be effective in improving cooling comfort, while typically being affordable solutions.<\/p>\n","protected":false},"excerpt":{"rendered":"\u201cBy the 2050s, median outdoor temperatures in Sydney’s hotter inland areas could rise by up to 5\u00b0C under…\n","protected":false},"author":2,"featured_media":46867,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[16008,34683,34682,12839,34684,34685,17070,247],"class_list":["post-46866","post","type-post","status-publish","format-standard","has-post-thumbnail","category-sydney","tag-architecture","tag-architecture-and-design","tag-government-politics","tag-health-medicine","tag-law-society","tag-news-opinion","tag-news-subscribers","tag-sydney"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/posts\/46866","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/comments?post=46866"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/posts\/46866\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/media\/46867"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/media?parent=46866"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/categories?post=46866"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/australia\/wp-json\/wp\/v2\/tags?post=46866"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
