TECHNOLOGY LICENSING OPPORTUNITY: Passive Radiative Thermostat (PRT)

The Passive Radiative Thermostat (PRT) is a smart, electricity-free coating technology from scientists at Los Alamos National Laboratory that automatically regulates temperature by adjusting how it absorbs and emits heat based on ambient conditions. Using a thermochromic phase-change material combined with engineered thin-film layers that control solar and infrared radiation, the system cools surfaces on hot days by reflecting sunlight and releasing heat to the sky and warms them on cold days by absorbing sunlight and minimizing heat loss all without sensors, controls or power input. Designed for integration into roofs, facades, windows, vehicles and outdoor equipment, the technology offers a scalable, low-maintenance pathway to reduce HVAC energy consumption, lower peak electrical loads,
