US Green Building Council Exam LEED-AP-ID+C Topic 5 Question 6 Discussion

Actual exam question for US Green Building Council's LEED-AP-ID+C exam

Question #: 6
Topic #: 5

After the construction and installation of all finishes and furnishing of a new 36,000 ft2 (3 344.5 m2) office space, what is the minimum total volume of outdoor air that is required during a non-phased flush-out procedure to achieve Indoor Environmental Quality Credit, Indoor Air Quality Assessment?

A126,000,000 ft3 (3 567 922.7 m3)

B378,000,000 ft3 (10 703 768.1 m3)

C504,000,000 ft3 (14 271 690.7 m3)

D522,000,000 ft3 (14 781 394.0 m3)

Show Suggested Answer

Suggested Answer: C

The LEED requirement for Indoor Environmental Quality Credit, Indoor Air Quality Assessment, specifies that after construction, a non-phased flush-out must supply a total air volume of 14,000 cubic feet of outdoor air per square foot of floor area1. For a new office space of 36,000 ft, the calculation would be:

36,000ft214,000ft3/ft2=504,000,000ft3

This aligns with option C, which is the correct answer.

Ah, the joys of HVAC calculations. I bet the person who wrote this question is sitting back, sipping their coffee, and chuckling at our struggling expressions. Well, joke's on them, I'm about to nail this one!

Option D, clearly. After all, a 'flush-out' procedure implies we need to flush out as much air as possible, like a super-sized version of those car washes with the giant brushes. Go big or go home, I always say!

Ah, the age-old question of how much air is enough. I say we just open all the windows and let Mother Nature handle it. Who needs fancy calculations when you've got a good old-fashioned breeze, am I right?

Hold on, I think I remember something about the minimum required volume. Wouldn't that mean option A is the correct answer? Wait, is this a trick question? I'm starting to second-guess myself now.

Hmm, let me think about this. I'd say option B looks about right, it's the biggest number so it must be the correct answer. After all, more is better when it comes to indoor air quality, right?
