Cool roofing is the fastest growing sector of the building industry, as building owners and facility managers realize the immediate and long-term benefits of roofs that stay cool in the sun. Studies exploring the energy efficiency, cost-effectiveness, and sustainability of cool roofs show that in warm or hot climates, substituting a cool roof for a conventional roof can:
- Reduce up to 15% of annual air-conditionaing use
- Cool interior spaces in buildings more naturally
- Reduce carbon emissions by lowering fossil fuel use
