In a multi-unit residential building, what requirements must be met for ETS control if the hallways and rooms have the same air pressure?
A: Meet the requirements of ASHRAE 62.1-2007
B: Weatherstrip all doors leading to common hallways
C: Use MERV 13 filters on all vents to common areas
D: Locate all exterior smoking areas 20 feet away from any outdoor air intakes

参考答案: B

本题解释:
Reference: Indoor Environmental Quality Prerequisite, Environmental Tobacco Smoke (ETS) Control

For residential projects Case 2 must be followed.

If the same air pressure exists between the units and the hallways, the pathways between the units must be sealed to prevent ETS transfer.

Note that Case 2 does not require a negative pressure differential for each unit, only that the unit does not leak too much air.
