Submeters 1 Establish permanently installed meters for at least two water subsystems through the following:
分项计量 通过以下方式为至少两个用水子系统建立永久计量表：
• Irrigation: Meter water systems serving at least 80% of the irrigated landscaped area.
• 灌溉：对服务于至少80%灌溉景观面积的系统进行计量。
• Indoor plumbing fixtures and fittings: Meter water systems serving at least 80% of
• 室内卫浴器具和配件：对服务于至少80%室内卫浴器具和配件的系统进行计量，
the indoor plumbing fixtures and fittings, either directly or by deducting all other measured water use from the measured total water consumption of the building and grounds.
可直接计量或从建筑和场地总用水量中扣除其他已计量用水。
• Cooling towers: Meter replacement water use of all cooling towers serving the facility.
• 冷却塔：对所有冷却塔的补水用水进行计量。
• Domestic hot water: Meter water use of at least 80% of the installed domestic hot

以确定真实再生水用量。
• Other process water: Meter at least 80% of expected daily water consumption for
• 其他工艺用水：对至少80%预期日用水消耗（加湿器、洗碗机、洗衣机、泳池等）进行计量。
process end uses, such as humidifiers, dishwashers, clothes washers, and pools. All meters, including whole-building meters, must be recorded at least weekly and used to regularly analyze time trends. If the building owner, management organization, or tenant owns the meter, it must be calibrated within the manufacturer’s recommended interval.
所有计量表（含整栋建筑计量表）须至少每周记录一次并定期分析时间趋势。若业主/管理方/租户拥有计量表，须按制造商建议间隔校准。
