Why enroll

Mastering indoor air pollution management can significantly enhance your career prospects in the HVAC, facilities management, and environmental health industries. With this expertise, you'll be in high demand as an Indoor Air Quality (IAQ) Specialist, HVAC System Designer, or Facilities Manager. Your knowledge will enable you to design and implement effective air quality control strategies, improving occupant health and productivity. You'll be competitive for senior roles like Senior HVAC Engineer, Environmental Health Specialist, or Sustainability Manager, and be well-positioned to pursue certifications like CIEC, CMC, or LEED AP. Unlock new opportunities and take your career to the next level with this specialized skillset.

What enrolled engineers say

2 verified reviews

The labs pushed me to notice a few sloppy habits around hvacr assumptions. Module 3’s lab where you model ACH changes and watch the PM2.5 decay curve, then size a MERV 13 vs HEPA and see the pressure drop math, stuck; it's close to what I check in infra reviews. Framed like a CI gate for buildings, measure/adjust/verify, so the obs mindset carried over. wasn't sold on the skimpy bit about sensor drift in prod spaces, but I've cleared up some long‑held mix-ups about CO2 as a proxy.

Good baseline for hvacr teams; it's geared for beginners and keeps costs visible, but it wasn't sold on advanced controls. The Module 2 table comparing MERV 8/13/16 pressure drop vs fan watts and the CO2 ppm walkthrough stuck, useful when scoping infra changes in prod; wished there was more on ongoing obs.

Questions and Answers

Q: You're on site doing pre-commissioning and you catch yourself googling "AHU pre commissioning checklist verify filter installation airflow direction" while standing in front of a newly installed MERV 13 bank. The GA shows correct filter size, but the supplier submittal pack is thin. What do you verify first before applying power to the supply fan?

A: A: Orientation and bypass are zero-power checks. If the arrows are wrong or there's a gap, everything downstream lies. B: ΔP means nothing until you know air is going the right way and not leaking around the frames. C: Jogging the fan before confirming physical install risks pulling filters off their seats. D: Paper compliance doesn't stop a backwards filter from dumping dust into the coil.

Q: During design review, someone asks you to justify the HEPA upgrade and you search "what does HEPA filter not protect against indoor air quality" to sanity-check the argument. In an occupied lab with solvent use, what hazard remains essentially unaffected by a HEPA filter alone?

A: A: That's exactly the particle size HEPA is meant to catch. B: Again particulate, even if the source is outdoors. C: Vapors pass straight through fibrous media; you need adsorption or dilution. D: Droplets behave like particles once airborne, filtration still helps.

Q: Operations calls because CO₂ readings are climbing in a conference area right after a controls change, and you're searching "CO2 rising after VAV minimum airflow reduction" on your phone. Outdoor air fraction was left unchanged at the AHU. What actually caused the spike, and what's the correct first response?

A: A: Outdoor air fraction stayed fixed, but total flow dropped. OA in cfm fell with it. B: Drift doesn't line up with a controls change across multiple rooms. C: Stratification doesn't create a sustained CO₂ rise tied to occupancy. D: Forcing the damper masks the real miss and can break humidity control.

Q: You're rough-checking a retrofit and type "estimate outdoor air ACH from cfm room volume" to see if the numbers smell right. A 1,000 ft² office with 10 ft ceilings gets 500 cfm of outdoor air. Order of magnitude, what air changes per hour does that represent?

A: A: Volume is 10,000 ft³. 500 cfm is 30,000 ft³/hr. That's about three air changes. B: That would imply only 5,000 ft³/hr, off by a factor of six. C: Mixing losses don't multiply flow by three. D: Occupancy doesn't change the math on volume and flow.
