Residential 住宅建筑专项要求

For residential spaces, follow the additional dwelling unit provisions below.

住宅空间须遵循以下额外的居住单元规定。

Dwelling Unit Provisions 居住单元规定

If the project building contains residential units, each dwelling unit must meet all the following requirements:

如项目建筑包含住宅单元，每个居住单元须满足以下所有要求：

• Mechanical ventilation / 机械通风：Design and install a dwelling-unit mechanical ventilation system that complies with ASHRAE 62.2-2022, Sections 4, 6.6, and 6.7. Supply and balanced mechanical ventilation systems must be designed and constructed to provide ventilation air directly from the outdoors. Mechanical ventilation systems are not required when the project meets the exception detailed in ASHRAE 62.2-2022, Section 4.1.1.
  设计并安装符合ASHRAE 62.2-2022第4、6.6和6.7节的居住单元机械通风系统。当项目满足ASHRAE 62.2-2022第4.1.1节详细列出的例外情况时，不需要机械通风系统。
• Kitchen and bathroom exhaust / 厨房和浴室排风：Design and install local mechanical exhaust systems in each kitchen and bathroom, including half baths, that comply with ASHRAE 62.2-2022, Sections 5 and 7. Exhaust air to the outdoors. Do not route exhaust ducts to terminate in attics or interstitial spaces. Recirculating range hoods or recirculating over-the-range microwaves do not satisfy the kitchen exhaust requirements. For exhaust hood systems capable of exhausting in excess of 400 cubic feet per minute (188 liters per second), provide makeup air at a rate approximately equal to the exhaust air rate. Makeup air systems must have a means of closure and be automatically controlled to start and operate simultaneously with the exhaust system. Use ENERGY STAR labeled bathroom exhaust fans in all bathrooms (including half baths) or performance equivalent for projects outside the U.S. An HRV heat recovery ventilator (HRV) or ERV energy recovery ventilator (ERV) may be used to exhaust single or multiple bathrooms if it has an efficacy level meeting the ENERGY STAR Technical Specifications for Residential Heat-Recovery Ventilators and Energy-Recovery Ventilators (H/ERVs), version 2.3 as certified by the Home Ventilating Institute.
  每个厨房和浴室（包括半卫）设计并安装局部机械排风系统，符合ASHRAE 62.2-2022第5和7节。排风应直接排至室外。不得将排风管道引至阁楼或夹层空间。循环式抽油烟机或循环式微波炉不能满足厨房排风要求。美国以外的项目须使用性能相当的浴室排风扇。可使用热回收通风器（HRV）或能量回收通风器（ERV）为单个或多个浴室排风。
• Unvented combustion appliances / 无通风燃烧设备：Unvented combustion appliances (ovens and ranges excluded) are not allowed.
  不允许使用无通风燃烧设备（烤箱和炉灶除外）。
• CO monitor / CO 监测器：A carbon monoxide (CO) monitor must be installed on each floor of each dwelling unit, hard-wired with a battery backup. CO monitors are required in all types of units, regardless of the type of equipment installed in the unit.
  每个居住单元的每一层须安装一氧化碳（CO）监测器，采用硬接线并配备电池备用。所有类型的单元均需要CO监测器，无论单元内安装何种类型的设备。
• Indoor fireplaces and woodstoves / 室内壁炉和燃木炉：Any indoor fireplaces and woodstoves must have solid glass enclosures or doors that seal when closed. Any indoor fireplaces and woodstoves that are not closed combustion or power-vented must pass a backdraft potential test to ensure that depressurization of the combustion appliance zone is less than 5 Pa.
  任何室内壁炉和燃木炉必须具有实心玻璃围护或在关闭时可密封的门。非封闭式燃烧或动力通风的室内壁炉和燃木炉必须通过回风潜力测试，确保燃烧设备区域的负压小于5 Pa。
• Space- and water-heating equipment / 空间及热水加热设备：Space- and water-heating equipment that involves combustion must be designed and installed with closed combustion (i.e., sealed supply air and exhaust ducting) or with power-vented exhaust or located in a detached utility building or open-air facility.
  涉及燃烧的空间和热水加热设备必须设计并安装为封闭式燃烧（即密封的供气和排气管道），或采用动力通风排气，或位于独立的辅助建筑或露天设施中。
