Since the summer of 2020, the civil engineering office in Zurich has been running a pilot project<\/a> to reduce heat. According to a press release<\/a> from the city of Zurich<\/a> , differently colored road surfaces were applied to Roggenstrasse in Zurich-West in order to measure the effect on the temperature. The results show that the light-colored coverings – in contrast to shadows from trees and houses – only have a minor influence on the temperature.<\/p>\n

For these measurements, new surfaces were installed on Roggenstrasse and the road was divided into three areas: a reference area made of conventional, street-gray asphalt and two areas with a beige and a reddish surface, according to the city’s statement. Cameras and embedded probes recorded the surface temperature and heat storage of the pads.<\/p>\n

The results now available show a minor effect of the light-colored deposits on the surface temperature. The reference surface in conventional gray was even about 2 degrees cooler on average than the two bright surfaces. This result can be explained by the shadow that trees and a high building temporarily cast on the reference area, it is said. It therefore heated up less.<\/p>\n

The differences between the two light surfaces were small. The beige covering stayed a little cooler than the reddish one. Calculations showed that if all surfaces had been exposed to the same amount of sunlight, the light surfaces would have been 2 degrees cooler than the reference area.<\/p>\n

The results of the pilot project clearly show how important shade and trees are for reducing heat in cities, according to the civil engineering office.<\/p>\n","protected":false},"excerpt":{"rendered":"
