Enhancing Airport Cooling with PDRC Technology: The Tokyo Haneda Experience

Welcome to the forefront of airport cooling technology, where Tokyo Haneda Airport’s adoption of passive daytime radiative cooling showcases a leap in sustainable design and passenger comfort. In this post, we delve into the transformative application of cool roofs and Radi-Cool’s PDRC technology, setting a benchmark in energy efficiency and environmental stewardship.


Airports worldwide are continually seeking methods to reduce their environmental footprint and enhance passenger experience. Passive daytime radiative cooling and cool roofs represent revolutionary approaches in this endeavor. By reflecting sunlight and emitting heat, these technologies significantly decrease the need for air conditioning, offering a sustainable solution to airport cooling needs.

Case Study Highlight

In 2020, the Tokyo Haneda Airport embarked on a pioneering pilot project, installing PDRC reflective film on the roof of a sky bridge. This initiative aimed to cut down air conditioning demand while improving the comfort levels of passengers and staff. The results were a testament to the potential of passive cooling technologies in large, energy-intensive settings.

Results and Benefits

The installation led to substantial cooling of both the roof surface and interior spaces, demonstrating the effectiveness of passive daytime radiative cooling. The technology not only curbed energy consumption but also contributed to a more comfortable and pleasant airport environment, enhancing the overall passenger experience.

Other Applications

The success story of Tokyo Haneda is not singular. Airports like Changi International in Singapore and Hangzhou Xiaoshan in China have also adopted PDRC films, reporting impressive energy savings and temperature reductions. These examples underscore the global applicability and benefits of cool roofs and passive cooling strategies in the aviation sector.


Tokyo Haneda’s successful implementation of passive daytime radiative cooling and cool roofs marks a significant stride in sustainable airport design. By prioritizing energy efficiency and passenger comfort, airports can significantly reduce their environmental impact while setting new standards for the future of aviation infrastructure.
