Try this: Coat streets white to cool S’pore

In Uncategorized on 29/07/2019 at 1:16 pm

I refer to Air conditioners make cities hotter, and to the fact that it’s really hot the last few weeks.

White streets in Los Angeles, California

The concrete jungle of LA gets up to 6F* hotter than the surrounding desert, with 2019 already setting records for hottest ever days, according to the US National Oceanic and Atmospheric Administration.

LA … aims to cool the city down by 3F** by 2035.

One of the city’s tactics is using a light-coloured material over one street in each of the 15 council districts, in order to test out the impact.

The material, known as “cool pavement”, reflects rather than absorbs the sun and so remains cooler than typical black roads.

However, it is more expensive and doesn’t yet meet safety standards for wider, busier streets in the city, hence the demo phase.

One “cool street” in Canoga Park measured 70F*** shortly after being laid, as opposed to 93F**** found on a nearby intersection road.

City officials also hope the cool pavements will help cool the insides of nearby buildings and lessen air pollution.

We are already using the other ways suggested in article including garden roofs, so why not try this.
