Design landscape features to reduce local heat island effects.
3 Reduce local heat island effects (1 point). Do one of the following:
a) Locate trees or other plantings to provide shading for at least 50% of sidewalks, patios, and driveways within 50 feet of the home. Shading should be calculated for noon on June 21, when the sun is directly overhead, based on five years’ growth.
b) Install light-colored, high-albedo materials or vegetation for at least 50% of sidewalks, patios, and driveways within 50 feet of the home. Acceptable strategies include the following:
- White concrete
- Open pavers (counting only the vegetation, not the pavers); and
- Any material with a solar reflectance index (SRI) of at least 29.
