Who we are

Who Are We?

We are Azure Era Energy Saving Technology (Hong Kong) Co., Ltd., formed by a team of professors from the Hong Kong University of Science and Technology and Zhejiang University. We focus on the research and application of optical temperature control technologies, including radiative cooling and heating. We are dedicated to providing zero-energy green solutions to help various industries achieve energy savings and emission reductions.

What Is Radiative Cooling? What Is the Principle of Your Technology?

The core of radiative cooling technology involves:

Reflection: Reflecting the majority of sunlight to reduce heat absorption.

Emission: Emitting thermal radiation in the 8-13 micrometer infrared range to dissipate heat through atmospheric windows.

This technology can lower the surface temperature of materials below ambient temperature during midday.
