-
Structures covered by energy generation systems, such as solar thermal collectors, photovoltaics (PVs), and wind turbines.
-
Architectural devices or structures. If the device or structure is a roof, it shall have an aged SR value of at least 0.28 as measured in accordance with ANSI/CRRC S100 . If the device or structure is not a roof, or if aged SR information is not available, at installation it must have an initial SR of at least 0.33 as measured in accordance with ANSI/CRRC S100.
-
Paving materials with an initial SR value of at least 0.33.
-
An open-grid pavement system (at least 50% unbound).
-
High-reflectance roof Use roofing materials that have an aged solar reflectance index (SRI) value equal to or greater than the values in Table 1. If aged SRI is not available, the roofing material shall have an initial SRI equal to or greater than the values in Table 1.
Table 1. Minimum SRI Value, By Roof Slope
| Col1 | Slope | Initial SRI | Aged SRI |
|---|---|---|---|
| Low-sloped roof | ≤ 2:12 | 82 | 64 |
| Steep-sloped roof | > 2:12 | 39 | 32 |
A roof area that consists of functional, usable spaces (e.g., helipads, recreation courts, swimming pools, and similar amenity areas) may meet the requirements of nonroof measures. Applicable roof area excludes roof area covered by mechanical equipment, solar energy panels, skylights, and any other appurtenances.
Vegetated roof Install a vegetated roof using native or adapted plant species.
AND/OR
Option 2. Parking Under Cover (1 point)
Place 100% of parking spaces under cover. Any roof used to shade or cover parking must meet at least one of the following criteria:
-
Have an aged SRI of at least 32. If aged value information is not available, use materials with an initial SRI of at least 39 at installation.
-
Be a vegetated roof.
-
Be covered by energy generation systems, such as solar thermal collectors, photovoltaics, and wind turbines.
