This portfolio strategy can be supported by analysis from the Cooling Singapore Initiative, led by SMU, NUS, NTU, ETH and different universities. In a latest paper, we argued for heat-smart methods in sizzling and humid cities; not single options, however measures that tackle hazard, publicity and vulnerability collectively.
The UN Setting Programme discovered that international cooling demand might greater than triple by 2050 beneath enterprise as ordinary, pushing cooling emissions to 7.2 billion tonnes of carbon dioxide-equivalent a yr.
A sustainable cooling pathway combining native warmth assessments, warmth motion plans, passive cooling, environment friendly applied sciences and cleaner energy might lower projected 2050 cooling emissions by 64 per cent, and by 97 per cent with speedy power-sector decarbonisation.
PRACTICAL HEAT MANAGEMENT LESSONS
What sensible classes can European cities draw from Singapore?
First, plan with communities, not merely for them. Warmth motion plans that exclude residents, employees, colleges, care suppliers and native companies will miss the place danger truly falls.
Second, goal mechanical cooling the place danger is highest. Hospitals, care houses, colleges, social housing, public transport and cooling shelters want protected indoor temperature requirements.
Third, retrofit buildings earlier than air-conditioning demand locks in and strains energy grids. Exterior shading, shutters, reflective roofs and funky partitions, ceiling followers, cross-ventilation and night time cooling can scale back indoor warmth and electrical energy demand.
