This passage 2 Academic IELTS Reading is a problem-solution structure. The problem: air-conditioning units generate 'spectacular and largely unnecessary energy use and carbon emissions'. The solution: use natural ventilation, as they did in 19th-century hospitals.This IELTS Reading is packed full of useful vocab like 'to squander energy' (= to waste) and 'it uses a FRACTION of the electricity/at a FRACTION of the energy cost' (=a small or tiny part, amount, or proportion of something).There were also some interesting uses of nouns as adjectives (wards in hospitals = hospital wards) - see my blog about this useful IELTS topic here:https://ieltsetc.com/2021/06/nouns-as-adjectives/and adjectives as nouns ('the prosperous' = the people who are prosperous and 'the public').Get all my reading tips and advice on my website:https://ieltsetc.com/ielts-reading/
