About Us

Hello, we’re Hearth Labs

Hearth Labs is a cleantech startup developing sensors to measure the radiative environment and finally quantify the missing half of thermal comfort. Our sensors can drastically reduce HVAC energy consumption while improving occupant thermal comfort.


Nicholas is a Researcher at Princeton with a background in computer science. He focuses on the hardware, software and algorithms for the SMART sensor.

CHAOS Lab, Princeton University

The Cooling and Heating for Architecturally Optimized Systems (CHAOS) Lab is an interdisciplinary research lab at Princeton. The first version of the SMART sensor was developed to quantify the performance of a radiative cooling structure known as the ThermoHelioDome.

Hearth Labs' patents for the SMART sensor technology

Intellectual Property

Research & Patents

We won multiple academic grants to develop the fundamental technology and explore its applications. We used the SMART sensor to fix thermal comfort problems and reduce energy consumption on Princeton's campus.
