Problem
Active cooling systems are energy-intensive and contribute to significant operational costs and environmental impact. Existing passive cooling solutions often lack the performance or versatility required for widespread adoption across diverse applications.
Solution
Entropy Lab develops PasteCool, a sustainable passive cooling coating that leverages advanced radiative and evaporative cooling principles. This water-based paint formulation is designed for application on building facades, rooftops, and solar photovoltaic panels to reduce surface temperatures. By enhancing solar reflectance and thermal emissivity, PasteCool mitigates heat absorption and promotes radiative heat dissipation. The inclusion of evaporative cooling properties allows for continued temperature reduction even in humid or rainy conditions, offering a more consistent and effective cooling performance compared to conventional coatings.
Target Audience
Target customers include building owners, facility managers, and solar energy providers seeking to reduce energy consumption and operational expenses associated with thermal management.
