7 Applications of Radiative Cooling in Transportation

As the world continues to grapple with the challenges of climate change, innovations in transportation play a pivotal role in reducing environmental impact. One such innovation that’s gaining momentum is the application of passive daytime radiative cooling in modern transportation. This cutting-edge technology offers the promise of both keeping us cool and making our journeys more energy-efficient. In this article, we’ll explore ten exciting uses of daytime radiative cooling in transportation that are shaping the future of mobility. Planes, trains, and automobiles are just the beginning!

By harnessing the power of daytime radiative cooling, modern transportation is becoming both cooler and more energy-efficient. These ten applications are just the tip of the iceberg, as researchers and engineers continue to explore new possibilities for this technology. As we strive to build a more sustainable future, radiative cooling in transportation offers an exciting pathway to drive cool and drive efficiently.

Mail Truck Passive Daytime Radiative Cooling

1.  Last Mile Delivery

Imagine a bustling urban landscape, where last-mile delivery drivers and mailmen zip through congested streets, ensuring your packages and mail reach your doorstep in record time. Now, picture a scorching summer day when the asphalt is sizzling and temperatures are soaring. While these dedicated drivers are racing to meet delivery deadlines, staying comfortable inside their vehicles can be a challenging ordeal. 

A string of recent news reports have brought light to the issue, with videos and accounts of drivers collapsing mid-delivery from heat exhaustion and heat stroke. According to OSHA, the job ranks fifth in heat-related fatalities, trailing only construction, agriculture, landscaping, and roofing.

There are no federal heat safety requirements in place for delivery drivers. In fact, as of 2023, of the 3,600 USPS delivery vehicles in sunny Arizona, less than 20% have air conditioning! The men and women of the USPS, Amazon, FedEx, and UPS shouldn’t have to risk their lives when temperatures soar. 

Passive daytime radiative cooling offers a sustainable solution to keep delivery drivers cool and efficient. Integrating radiative cooling films and membranes onto the roofs of vehicles means reduced cabin temperatures, improved working conditions, and happier, more productive drivers.
