How to combat urban killer heat?

In our weekly news filter, we share the most interesting articles related to technology and the future of cities and buildings.

This week, the Union of Concerned Scientists published their report “Killer Heat in the United States: The Future of Dangerously Hot Days”. The report projects large and widespread spikes in high-heat days across the U.S. as climate change worsens. Extreme heat is poised to rise steeply in frequency and severity over the coming decades, bringing unprecedented health risks for people and communities across the country, the study finds. Extreme heat is not only a threat to public health, but it can also put a strain on or damage infrastructure.


Green Corridor

Clever city planning can play a crucial role in providing cooling solutions for cities. Examples of this are green roofs and green corridors or higher standards of building design. This week UN Environment published an article about the award winning Green Corridor Project in the city of Medellín (Colombia). Medellín’s city authorities transformed the verges of 18 roads and 12 waterways into a green paradise that reduces the impact of the heat island effect. Check out this video about the Green Corridor Project.


Other solutions to combat the ‘Urban Heat Islands’ are to use cool wall paints. Last year, Berkeley Lab researchers found out that Egyptian blue fluorescent cool pigment can boost energy efficiency by cooling rooftops and walls, and could also enable solar generation of electricity via windows. Used on windows tinted with the blue, photovoltaic cells on the edges can convert the fluoresced near-infrared energy to electricity.

Similarly, UNStudio together with Monopol Colors has just recently launched ‘The Coolest White’, an ultra-durable paint that protects buildings and urban structures from excessive solar radiation – thus slowing down the urban heat island effect.
