Turning Sunlight into Savings: The Business Case for Self-Cooling Paint

Problem

Conventional exterior paints and roof coatings absorb a large portion of solar radiation, causing surface temperatures to rise sharply under direct sunlight. In buildings, this leads to higher indoor temperatures, increased air-conditioning load, and elevated energy costs. In industrial facilities and infrastructure, excessive heat accelerates material aging, coating degradation, and thermal stress, shortening maintenance cycles and reducing asset lifespan.

Solution

Manufacturers adopted Self-Cooling Paint, an advanced coating system designed to reflect solar radiation and emit absorbed heat efficiently through radiative cooling mechanisms. By engineering pigments, binders, and micro-/nano-scale fillers, these coatings deliver:

High solar reflectance (typically 0.85-0.95)
Strong mid-infrared thermal emissivity (≥0.90)
Surface temperature reduction of 5-15 °C under peak sunlight
Improved UV resistance and long-term weather durability

Self-cooling paint passively lowers surface temperature without electricity, enabling continuous cooling performance throughout the day.

Result

After implementation, end users reported measurable benefits:

Building cooling energy consumption reduced by 8-20%
Roof and façade service life extended by 20-35%
Indoor thermal comfort significantly improved during heat waves

Overall, self-cooling paint improved energy efficiency, reduced carbon emissions, and enhanced durability across residential, commercial, and industrial applications.

Detailed Application Scenario

The real estate developer applied AkzoNobel's self-cooling paint across large commercial rooftops and building façades in a hot-climate region. The coating's high solar reflectance significantly reduced rooftop surface temperatures during peak summer hours, lowering heat transfer into interior spaces.

As a result, HVAC systems operated at reduced load, delivering meaningful energy savings and improved tenant comfort. The paint's strong UV and weather resistance ensured long-term performance with minimal maintenance. By replacing conventional exterior coatings, the project demonstrated how self-cooling paint supports energy-efficient building design, climate resilience, and cost-effective sustainability strategies.
