AI Contract Overview

The Passive Radiative Thermostat (PRT) is an innovative, electricity-free coating technology developed by Los Alamos National Laboratory that autonomously regulates temperature by modulating heat absorption and emission in response to ambient conditions. Utilizing a thermochromic phase-change material integrated with engineered thin-film layers, PRT reflects sunlight and radiates heat to cool surfaces during hot conditions, while absorbing sunlight and reducing heat loss to warm surfaces in cold conditions—all without the need for sensors, controls, or external power. This scalable, low-maintenance solution is designed for diverse applications including roofs, building facades, windows, vehicles, outdoor equipment, and more, offering significant potential for reducing HVAC energy consumption, minimizing peak electrical loads, and supporting decarbonization efforts across multiple sectors. Currently at Technology Readiness Level 2 and protected under US Patent No. 11,359,839, the PRT technology is suited for markets such as building and construction, automotive and transportation, energy and utilities, industrial manufacturing, data centers, telecommunications, and consumer outdoor products. Los Alamos National Laboratory invites interested companies to explore licensing opportunities through exclusive or non-exclusive agreements, facilitating the transfer of this cutting-edge invention for commercial use. With no power requirements, year-round effectiveness, and compatibility with thin-film integration, PRT represents a promising advance in passive thermal management technologies. The solicitation for licensing opportunities is managed by the Department of Energy contractor in Columbus, Ohio, with a response deadline set for early May 2026.

Full Description

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, improve thermal comfort and support decarbonization goals across building, mobility and industrial markets.

How it Works:

Passive Radiative Thermostat is a temperature-responsive surface coating that automatically adjusts how it manages heat based on surrounding conditions. PRT incorporates a material that naturally changes its thermal behavior at a preset temperature, allowing the surface to release excess heat when it is hot and retain warmth when it is cold. By intelligently interacting with sunlight and infrared heat, the system stabilizes surface temperature without requiring electricity, sensors or moving parts. The result is a passive, self-regulating thermal control approach that improves temperature management.

Key Advantages:

Automatic temperature regulation
No power required
Year-round performance
Energy savings potential
Thin-film compatibility
Scalable and low maintenance

Market Applications:

Building & Construction (roofs, facades, exterior surfaces, window systems)
Automotive & Transportation (vehicle exteriors, cabin surfaces, transport equipment)
Energy & Utilities (power equipment enclosures, storage systems, grid infrastructure)
Industrial & Manufacturing (outdoor equipment, tanks, processing facilities)
Data Centers & Telecommunications (equipment shelters, edge computing enclosures)
Consumer & Outdoor Products (electronics housings, smart devices, outdoor installations)
