| Strategy / 策略 | Requirement / 要求 |
|---|---|
| Shade from trees (within 5 years of occupancy) / 树木遮荫（入住5年内） | Provide shade for 50% of hardscape area at peak sun. 高峰日照时为50%硬质铺装提供遮荫。 |
| Shade from structures / 构筑物遮荫 | Shading devices with an SRI of at least 29. 遮阳装置SRI≥29。 |
| Shade from architectural devices / 建筑装置遮荫 | Structures with aged SRI of at least 29. 建筑结构老化SRI≥29。 |
| Shade from vegetated structures / 植被结构遮荫 | Vegetated pergolas, trellises. 植被化花架、格栅。 |
| Paving materials with high SRI / 高SRI铺装材料 | Aged SRI ≥29. 老化SRI≥29。 |
| Open-grid pavement system / 透空格栅铺装系统 | At least 50% unbound. 至少50%为未粘结。 |
Use roofing materials that have an aged SRI equal to or greater than the values in Table 1, for a minimum of 75% of the roof area of all new buildings within the project; or install a vegetated roof system (green roof).
对于项目内所有新建建筑中至少 75% 的屋顶面积，使用老化 SRI 不低于表 1 数值的屋面材料；或安装植被屋顶系统（绿色屋顶）。
| Roof Slope / 屋顶坡度 | Minimum Aged SRI Value / 最低老化 SRI 值 |
|---|---|
| Low-sloped (≤ 2:12) / 低坡度（≤ 2:12） | 64 |
| Steep-sloped (> 2:12) / 陡坡度（> 2:12） | 39 |
Cover a minimum of 75% of the total parking spaces with a vegetated roof or a roof that has a minimum aged SRI of 64 (low slope) or 39 (steep slope). The roof must also meet the requirements of Option 1 regarding Nonroof measures.
用植被屋顶或最低老化 SRI 达 64（低坡）/ 39（陡坡）的屋顶覆盖至少 75% 的停车位总数。该屋顶还必须满足选项1中对非屋顶措施的要求。
Meet Option 1, and additionally demonstrate a 3-Dimensional surface-area-weighted average SRI of at least 29 for all hardscape areas and all roofs, or include a vegetated roof that covers 100% of the roof area.
满足选项1要求，并且额外证明：所有硬质铺装和所有屋顶的3D表面积加权平均SRI至少达29，或采用100%覆盖屋顶面积的植被屋顶。
For school projects, install a vegetated roof or a roof with a minimum aged SRI of 64 (low slope) or 39 (steep slope) for 100% of the roof area and achieve 75% hardscape treatment of Option 1 nonroof measures to earn 2 points under Option 3.
学校项目须为100%屋顶面积安装植被屋顶或满足最低SRI要求的屋顶，并达到选项1中非屋顶措施的75%硬质铺装处理，方可获得选项3下的2分。
