IE Q Prerequisite 2: Environmental Tobacco Smoke (ETS) Control
Required

Intent
To prevent or minimize exposure of building occupants, indoor surfaces and ventilation air distribution systems to environmental tobacco smoke (ETS).

Requirements
OPTION 1
Prohibit smoking in the building.
Prohibit on-property smoking within 25 feet of entries, outdoor air intakes and operable windows. Provide
signage to allow smoking in designated areas, prohibit smoking in designated areas or prohibit smoking on the entire property.
OR
OPTION 2
CASE 1. Non-Residential Projects
Prohibit smoking in the building except in designated smoking areas.
Prohibit on-property smoking within 25 feet of entries, outdoor air intakes and operable windows. Provide
signage to allow smoking in designated areas, prohibit smoking in designated areas or prohibit smoking on the entire property.
Provide designated smoking rooms designed to contain, capture and remove ETS from the building. At a
minimum, the smoking room must be directly exhausted to the outdoors, away from air intakes and building
entry paths, with no recirculation of ETS-containing air to nonsmoking areas and enclosed with impermeable
deck-to-deck partitions. Operate exhaust sufficient to create a negative pressure differential with the
surrounding spaces of at least an average of 5 Pascals (Pa) (0.02 inches of water gauge) and a minimum of 1 Pa (0.004 inches of water gauge) when the doors to the smoking rooms are closed. Verify performance of the smoking rooms’ differential air pressures by conducting 15 minutes of measurement, with a minimum of 1 measurement every 10 seconds, of the differential pressure in the smoking room with respect to each adjacent area and in each adjacent vertical chase with the doors to the smoking room closed. Conduct the testing with each space configured for worst-case conditions of transport of air from the smoking rooms (with closed doors) to adjacent spaces.
CASE 2. Residential and Hospitality Projects
Prohibit smoking in all common areas of the building.
Locate any exterior designated smoking areas, including balconies where smoking is permitted, at least 25 feet from entries, outdoor air intakes and operable windows opening to common areas.
Prohibit on-property smoking within 25 feet of entries, outdoor air intakes and operable windows. Provide
signage to allow smoking in designated areas, prohibit smoking in designated areas or prohibit smoking on the entire property.Weather-strip all exterior doors and operable windows in the residential units to minimize leakage from outdoors.
Minimize uncontrolled pathways for ETS transfer between individual residential units by sealing penetrations in walls, ceilings and floors in the residential units and by sealing vertical chases adjacent to the units.
Weather-strip all doors in the residential units leading to common hallways to minimize air leakage into the
hallway1. Demonstrate acceptable sealing of residential units by a blower door test conducted in accordance with ANSI/ASTM-E779-03, Standard Test Method for Determining Air Leakage Rate By Fan Pressurization.
Use the progressive sampling methodology defined in Chapter 4 (Compliance Through Quality Construction) of the Residential Manual for Compliance with California’s 2001 Energy Efficiency Standards. Residential units must demonstrate less than 1.25 square inches leakage area per 100 square feet of enclosure area (i.e., sum of all wall, ceiling and floor areas).

Potential Technologies & Strategies
Prohibit smoking in commercial buildings or effectively control the ventilation air in smoking rooms. For residential buildings, prohibit smoking in common areas and design building envelope and systems to minimize ETS transfer among dwelling units.


IEQ P2:吸烟环境控制(ETS)
必须

目的
将建筑用户、室内表面、通风系统暴露于烟草气降到最低程度。

要求
情形1.所有工程
选项1
建筑内禁止吸烟。
在距入口、外门、取风口、可开启窗的25英尺范围内禁止吸烟，提供指定吸烟区，或指定
禁烟区，或整个建筑范围禁烟。
或者
选项2
除指定区域外，全建筑禁烟。
建筑实体、新风入口和可开启窗的25英尺范围内实施禁烟。在设定的吸烟区域给予提示，禁
烟区也要有标识提示。
建筑中的吸烟室应设置排烟设施，烟气排放至少要直接排放室外，并远离建筑入口、新风进
口，防止循环进入室内，吸烟区域与非吸烟区域要有顶到顶的隔墙，排放装置运行时，当吸
烟室关门时，可使吸烟区域相对于周边区域至少有一个平均5Pa、最低1Pa的负压差。
检测吸烟区压差性能时，每10秒测量一次，测量15分钟，关闭吸烟室的门，取最不利的位置
进行测量。
情形2. 仅对居住建筑和医院建筑
建筑中所有公共区域禁烟。
所有指定的吸烟区域，包括室外阳台，都必须距离建筑实体、入口、新风入口、公共区域可
开启窗25英尺范围之外。
距建筑实体、入口、新风入口和可开启窗25英尺范围内禁烟，所有禁烟区和指定的吸烟区都
必须有标识表明。
居住单元的外门、窗加装密封条防止空气渗入。
密封居住单元间的墙体、楼板和竖管的透风通道，防止烟气窜流。
通向公共区域的门加装密封条，减少向公共走道1的空气泄漏.
采用标准ANSI/ASTM E779-03标准的方法，进行鼓风门气密性检测，说明居住单元的密封符
合。按照加州2001节能标准的居住建筑手册，采取逐步进阶采样法，证明其围合面积(所有墙
体、顶地板面积)中每百平方英尺的渗漏面积不大于1.25英寸。

技术措施和策略
商业建筑中禁烟或吸烟室配置有效通风。居住建筑公共区域禁烟，和防止各居住单元间烟气窜
行。
