A contractor is documenting an IAQ plan that will be provided to each sub-contractor working on a major renovation project. Part of the building will remain occupied during the renovation. What steps should the contractor take to reduce indoor air quality problems due to the construction process?
A: Increase the ventilation to all occupied spaces by at least 30% above the minimum required by ASHRAE 62.1
B: Conduct high pollution activities during off hours
C: Clean any roll-out mats in front of the building at least weekly
D: Install filtration with a MERV 13 or better rating for both return and outside air

参考答案: B

本题解释:
Notes: The question is asking about Construction IAQ Management Plan but only referring to the intent.
The correct choice comes from the SMACNA Scheduling requirements. If there are occupants in the building during construction try to conduct tasks that have pollution potential during the off-hours of the building when occupants are not present. Painting is a good example since paint can give off a lot of fumes.
