REQUIREMENTS 要求

OPTION 1 ASHRAE 90.1-2019

Comply with ANSI/ASHRAE/IES Standard 90.1-2019 with addendum cr. Use any applicable compliance path in ASHRAE 90.1, Section 4.2.

符合 ANSI/ASHRAE/IES 标准 90.1-2019（含附录 cr）。可使用 ASHRAE 90.1 第 4.2 节中的任何适用合规路径。

Performance Rating Method 合规路径的特殊处理

For projects applying the Normative Appendix G, Performance Rating Method compliance path, the future source energy metric may be used in place of cost:

对于采用规范性附录 G（性能评级方法）合规路径的项目，可使用未来源能源指标替代费用：

• Replace all references to cost with future source energy. Use an electric site-to-source energy conversion factor of 2.0 based on future projections for the U.S. A lower national average value may be used as applicable for projects outside of the U.S.
  将所有费用引用替换为未来源能源。美国项目基于未来预测采用电力场地到源端转换系数 2.0。美国境外项目可采用适用的更低全国平均值。
• Replace ASHRAE 90.1-2019, Table 4.2.1.1, Building Performance Factors (BPFs), with the BPFs derived for the future source energy metric in Table 1.
  将 ASHRAE 90.1-2019 表 4.2.1.1 建筑性能系数（BPFs）替换为表 1 中未来源能源指标导出的 BPFs。

Table 1. ASHRAE 90.1-2019 — Equivalent Building Performance Factors for a Future Source Energy Metric

— OR 或者 —

OPTION 2 ASHRAE 90.1-2022

Comply with ANSI/ASHRAE/IES Standard 90.1-2022. Use any applicable compliance path in ASHRAE 90.1, Section 4.2.

符合 ANSI/ASHRAE/IES 标准 90.1-2022。可使用 ASHRAE 90.1 第 4.2 节中的任何适用合规路径。

Performance Rating Method 合规路径的特殊处理

For projects applying the Normative Appendix G, Performance Rating Method compliance path, one of the following metrics may be used in place of cost:

对于采用规范性附录 G（性能评级方法）合规路径的项目，可使用以下任一指标替代费用：

• Future source energy 未来源能源
  • Replace all references to cost with future source energy. Use an electric site-to-source energy conversion factor of 2.0 based on future projections for the U.S. A lower national average value may be used as applicable for projects outside of the U.S.
    将所有费用引用替换为未来源能源。美国项目采用转换系数 2.0，美国境外可采用更低的全国平均值。
  • Replace ASHRAE 90.1-2022, Table 4.2.1.1, Building Performance Factors (BPFs), with the BPFs derived for the future source energy metric in Table 2.
    替换 ASHRAE 90.1-2022 表 4.2.1.1 的 BPFs 为表 2 的值。
• Site energy or source energy documented using ASHRAE 90.1-2022, Informative Appendix I.
  使用 ASHRAE 90.1-2022 信息附录 I 记录的场地能源或源能源。
