LEED (Leadership in Energy and Environmental Design) is a rating system for high-performance environmentally sustainable buildings.
LEED certification refers to the building as a whole, certifying its environmental impact and sustainability, and was developed in the US in the early 90s and introduced into Italy by the Green Building Council Italia in 2008.
The certification system is based on a series of credits awarded for different categories. More specifically, cool roofs can earn points towards certification under:
- Category 1 Sustainable sites
- Credit 7.2 Heat island effect - Roof
In order to achieve the credit for reducing the heat island effect, the finished roof should:
- Have an SRI ≥ 78 (for roofs with a slope ≤15%)
- Have an SRI ≥ 29 (for roofs with a slope >15%)
