"Radi-cool" is a radiative cooling paint developed by Idemitsu Energy Solutions and Radicool Japan that helps reduce building temperatures by reflecting solar heat and emitting infrared radiation.

What were the main findings of the demonstration project?

The project confirmed that "Radi-cool" can reduce air conditioning power consumption by up to 31.7% and an average of 18.1% under specific meteorological conditions. It also reduced roof surface temperature by up to 34.3℃ and the space under the roof by up to 9.7℃.

Where was the demonstration project conducted?

The demonstration project was conducted at the "Hakata Port Bayside Museum" in Fukuoka City.

What is the significance of this technology for Fukuoka City?

Fukuoka City aims to achieve net-zero greenhouse gas emissions by 2040. This technology contributes to reducing energy consumption and greenhouse gas emissions from buildings, supporting the city's decarbonization goals.

What conditions were used to compare the energy savings?

The comparison was made under strict meteorological conditions, ensuring minimal variation in total solar irradiance (±0.3 MJ/day) and maximum temperature difference (less than ±1.0℃) between the painted and unpainted surfaces.
