Urban heat islands in Australian cities

Australian cities store summer in bitumen, west-facing brick and roofs that were chosen for a milder century. The extra heat arrives at night, when the streets should be giving it back. Tree canopy, pale surfaces and renter-scale tactics are how a suburb stops being a storage heater.

Home energy in a warming climate

Australian houses were built for a milder century and now ask the grid to finish the job. Insulation, ceiling fans, a shaded western window and a split system used with manners keep a room liveable. Renters have a shorter list; blackouts make that list shorter still.
