“Findings from the study are not just relevant for cities in Singapore where it is hot all year round, but for other urban areas around the world too,” said Dr. Wan Man Pun.
How can paint be used to combat climate change? This is what a recent study published in Sustainable Cities and Society hopes to address as a team of researchers from Singapore investigated real-world applications regarding how cool paint coatings that reflect the Sun’s heat could be attributed to enabling people to feel up to 34.7 degrees Fahrenheit (1.5 degrees Celsius) cooler compared to traditional city pavement. This study holds the potential to produce more comfortable city environments, especially with summer heats becoming warmer every year.
For the study, the researchers covered roads, walls, and roofs of an industrialized area of western Singapore consisting of almost 130,000 square feet (12,000 square meters) containing several multi-storied buildings. Over a 24-hour period, the researchers discovered that afternoon temperatures within the coated environment were up to 35.6 degrees Fahrenheit (2 degrees Celsius) cooler compared to non-coated surroundings. Additionally, the team used the Universal Thermal Climate Index to measure temperature comfort levels for locals walking through the area, discovering these individuals experienced up to 34.7 degrees Fahrenheit (1.5 degrees Celsius) cooler because of the cool paint coatings.
