Ventilation and IAQ

When you have to individually go verify whether 128 air curtains meant to ensure air balance in the original design’s branch ductwork are still there or not, you’re not having an easy time of it.

Analytics to workorder management, energy audits to light meters — the spectrum of apps for facility engineering tasks continues to get wider and more versatile.

Choosing not to sample every system can be a gamble, but here are some ways to lower your risk.

The research is consistent over the years, and the cost of low humidity continues to rise. Even our increasingly computer-oriented lifestyle exacerbates the problem.

The symptoms are familiar: hot and cold complaints, higher-than-expected costs, etc. Here’s a look at how the retrocommissioning process should work to tackle these and other developments for your facility.

So you’ve decided on your sample size. What next? What happens when a system failure is found?

An air handling unit that hasn’t worked since, well, ever. Chillers that have to work more often as a result — and an extra chiller just to attack the affected zone. These were the obvious symptoms, but what was the cause?

A few are more familiar and worth a reminder, while some are pretty sneaky. Others may have gotten there before the first occupant. In any event, any “sustainable facility” can sustain IAQ damage without attention to these sorts of risks.
