WATER EFFICIENCY PERFORMANCE WEc1 1–14 points
节水绩效 WEc1 1-14分
To reduce potable water consumption and the associated energy consumption and carbon emissions required to treat and distribute water, and to preserve potable water resources through an efficiency-first approach.
减少饮用水消耗及相关处理配送能耗和碳排放，通过效率优先方法保护饮用水资源。
Water Performance 1–14 Points are awarded based on total potable water consumption during a 12-month reporting period using the metric of gallons per square foot per year (or liters per meter per year). To earn 1 point, meet the baseline water use intensity threshold for the applicable space type as shown in Table 1. To earn additional points, demonstrate a percent reduction from the baseline water use intensity threshold as shown in Table 2.
