How Passive Radiative Cooling Coatings Protect Livestock and Greenhouses from Heat Stress

For operators of commercial poultry farms, livestock housing, and agricultural greenhouses, summer heatwaves pose a severe financial threat. Heavy metal roofs and plastic greenhouse canopies act like giant solar collectors, absorbing intense radiant heat all day long. Inside poultry houses and swine barns, temperatures routinely surge past safe operational limits. Heat stress in livestock triggers rapid drops in feed efficiency, reduces egg production, and leads to high animal mortality rates. To battle heat stress, farm owners run massive ventilation fans and evaporative cooling pads continuously, driving electricity bills to unsustainable levels.

Traditional cooling methods like roof water sprinklers or interior insulation blankets come with heavy operational drawbacks. Water spraying wastes thousands of gallons of water daily, accelerates roof rust, and increases humidity inside the barn. High humidity combined with heat makes heat stress even more dangerous for animals. Bulky interior insulation blankets easily trap moisture, harbor bacteria, and degrade quickly in humid agricultural environments.

Agricultural facility operators are solving this summer cooling challenge at the source by applying a liquid passive radiative cooling coating directly onto roofs and outer canopies.

Engineered with advanced optical materials, a spray-applied passive radiative cooling coating works through a zero-energy physical mechanism. First, it reflects over ninety-five percent of direct solar radiation back into the sky before the roof substrate can absorb thermal energy. Second, it emits internal heat directly through the atmospheric window into deep space.

Applying a high-performance passive radiative cooling coating keeps roof surface temperatures significantly below ambient air levels without consuming a single watt of electricity. Indoor temperatures drop naturally, preventing severe heat stress in poultry and livestock. Farm managers cut electricity expenses for large ventilation fans, eliminate water waste from sprinklers, and maintain healthy, high-yield agricultural production throughout the hottest summer months.
