Driven by rapid urbanisation and global climate change, the increasing frequency intensity of Urban Heat Island effect poses significant risks to health well-being urban dwellers across world. To combat extreme heat ensure a safe level thermal comfort for residents, innovative sustainable technologies, such as green infrastructure cool roof coatings, have been incorporated into building design planning. This study aims evaluate compare effectiveness six different coating brands in reducing surface temperatures under harsh fast-changing conditions Melbourne, Australia. A pilot-sized experimental was installed on rooftop an existing office monitor temperature variations using infrared camera, accompanied statistical analysis potential reductions varying weather sky conditions. The results this show that application coatings reduced at least 8.7 °C up 34.2 °C, corresponding 13.2% 53.6% from maximum temperature, respectively. When comparing paint brands, it observed Brand 4 demonstrated best performance, minimum value 34.3 (45.5% reduction) when 62.9 °C. On other hand, 5 showed effective performance but still achieved reduction 15.8 (25.1% reduction). highlights mitigation strategy lowering temperatures. Alongside strategies, roofs walls, offer viable solution buildings.
