Exercises
1. Put together a CPM schedule for items for SMACNA and the other requirements for IEQc3.1
and IEQc3.2. (See Chap. 8 for information on a CPM.)
A. With procurement staggered
B. With on-site protected storage
C. For sequencing installation of absorbent materials
2. Make a site plan with staging areas for material protection.
A. Calculate the size of the covered areas needed.
B. Determine the area needed for the staging and access.
C. Put these items on the plan.

3. When we breathe outside air, we inhale air with oxygen at about 21 percent (volumetric) and
carbon dioxide (CO ) at around 380 ppm (0.038 percent volumetric) and exhale air that has a little
2
less oxygen (a bunch more water) and around 4.5 percent CO , which is then rapidly diluted by
2
the air around it. Typically, you can estimate that sedentary activities in a typical space with proper
ventilation will raise the CO concentrations by about 350 ppm. Sedentary activities are said to be
2
1 Met (metabolic rate), which is a measure of the rate at which we expend energy, which can also
represent the rate at which we exhale CO . Vigorous exercise might be about 6 Met.
2
A. In a room with computer programmers and typical ventilation, estimate what you might
expect the concentration of CO to be (in ppm and also percent volumetric).
2
B. Estimate what this concentration might be in a jazzercise room if you do not increase
the ventilation from the level in the computer room (in ppm and percent volumetric).
(Many times the CO alarm is set at 1000 ppm. CO is considered toxic at about 5 percent
2 2
volumetric.)
4. For IEQc3.1 and IEQc5 there are requirements to have particulate filtering capabilities on the
air handlers based on the ASHRAE MERV (minimum efficiency reporting value) ratings. For these
ratings, typical airborne particulates are categorized into the following size ranges: 0.3 to
1 μm, 1 to 3 μm, and 3 to 10 μm. The micrometer (abbreviated μm) is given as an average diameter
