INTENT 意图

To design for increased indoor air quality (IAQ) to better protect the health of building occupants.

为提高室内空气质量（IAQ）而进行设计，以更好地保护建筑使用者的健康。

REQUIREMENTS 要求

Design the building to exceed the requirements of ASHRAE 62.1-2022, Section 6. If using the ventilation rate procedure to comply with EQp2: Fundamental Air Quality, use Option 1 or Option 2; if using the IAQ procedure, use Option 2.

建筑设计须超越ASHRAE 62.1-2022第6节的要求。如使用通风速率法来满足EQp2基础空气质量，可选择选项1或选项2；如使用IAQ法，须选择选项2。

Option 1. Increased Ventilation (1 point) 增加通风量（1分）

Increase breathing zone outdoor air ventilation rates by at least 15% above the minimum rates (for 1 point, or 30% for exemplary performance) as determined in EQp2: Fundamental Air Quality.

将呼吸区室外空气通风速率提高至EQp2基础空气质量确定的最低速率以上至少15%（1分），或30%（卓越表现）。

Increased outdoor air rates should be provided to 95% of all regularly occupied spaces.

提高后的室外空气速率应覆盖95%的所有常规使用空间。

OR — Option 2. Enhanced Indoor Air Quality Design (1 point) 增强型室内空气质量设计（1分）

In addition to the design compounds and design limits outlined in ASHRAE 62.1-2022, Tables 6-5 and 6-6, design and verify enhanced IAQ using the lower design limits listed below in Table 1.

除ASHRAE 62.1-2022表6-5和6-6中列出的设计化合物和设计限值外，使用下表1中列出的更严格的设计限值来设计和验证增强型IAQ。
