Phoenix ‘Cool Pavement’ Technology Releases One-Year Project Results
After being used for a year in a few neighborhoods, the Phoenix ‘cool pavement’ technology project became known.
Phoenix – New technology could cool the city Phoenix – It is said “Cool pavementAnd reduces heat in asphalt and concrete urban areas.
The city has been working on this project for about a year to see that technology is cooling down some neighborhoods in the city. Cool pavement is a technology used to cool asphalt and concrete, and the city has chosen a number of neighborhoods to try.
“We want to improve the lives of our residents in this city,” says Ruben Lolli, project manager for the city.
How does the technology work?
It has reflective and light color and chemical properties. Instead of absorbing heat like a dark asphalt, it absorbs sunlight into the atmosphere.
“The idea is to reduce the temperature on the sidewalk,” says Lollipop.
It has the potential to reduce Urban Heat Islands, Save energy in buildings and reduce the need for air conditioning in buildings.
The tropical islands have been described by the Environmental Protection Agency as “urban cities with high temperatures in remote areas.” Structures such as buildings, roads, and other infrastructure absorb and regenerate solar forest heat more than natural landscapes such as forests and water bodies. »
October 2020 ReportHeather Murphy, a spokeswoman for the Department of Road Transport, said Phoenix is using cool pavement at nine stations representing different urban features. Applications are expected to be completed by the end of the month.
Groundwater reduction can have direct benefits in reducing air temperature, which contributes to heat-related illnesses, air quality, and energy use.
Lolly: “Extreme heat affects people. It’s a part we can play to improve. ”
What were the results?
On Tuesday night, researchers from Phoenix City and Arizona State University announced their findings on the technology.
On hot days, they measure air, surface, and radiation temperature four times a day. Those measurements were compared with standard asphalt areas.
The researchers asked people in the cold pavement area about their experiences.
They found that the floor temperature of the pavement was 10 to 12 degrees Fahrenheit[10 to 12 ° C]. Temperatures were also as low as .3 degrees during the day.
They say the slightest difference may be due to the shade, the use of sidewalks in small areas, and the mixing of air from untreated areas. However, the sidewalk had a lower floor temperature at any time of the day compared to standard asphalt.
Other findings include:
- In the afternoon, exposure to human heat was 5.5 degrees Fahrenheit[5.5 ° F]due to the high temperature, but it was similar to walking on a concrete concrete pavement.
- Surface sunlight has reached 19 to 30 percent in all eight neighborhoods in the region from 33 to 38 percent in 10 to 10 months. The incidence of untreated asphalt is only 12 percent.
Cool pavement costs more than traditional asphalt, but researchers say the benefits far outweigh the differences.
