How Four Cities Are Cooling Down Creatively

I grabbed some quotes for those short on time. More details on everything are in the article.

In São Paulo’s favelas, low-income communities are building their own green roofs. These affordable vinyl sheet roofs were created by Teto Verde Favela, a nonprofit founded by local Luis Cassiano.

In place of traditional air-conditioning, Seville has turned to a 3,000-year-old solution. With the help of two scientists, the city in southern Spain is reviving a Middle Eastern technology: qanats, underground channels that transport water from higher to lower altitudes and drive the coolness upwards.

A simple approach to heat is helping Singapore address its urban heat challenges: painting buildings and other surfaces with reflective paint.

Munich’s climate-friendly cooling system utilizes natural energy from underground water streams. According to the city utility of Munich, Stadtwerke Muenchen (SWM), the use of these natural cold water streams has resulted in energy savings in the city of 70 percent compared to traditional cooling technology like air conditioning. Thanks to the city’s cooling system, more than 80,000 residents in Munich receive ecological energy.
