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?
The available LEED credits and most obvious energy-saving possibilities are one thing. The potential for a ripple effect of system-wide savings by deploying VFDs as part of better overall monitoring are another.
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.
Reviewing documents, sizing equipment and systems, and sketching on the go: got an app for that? Also, we compare tablet vs. phone and the advantages or worries that come with taking your tablet into imperfect field conditions. How do you use yours?
After a brief hiatus, we are resuming exploration of the tablet as engineering tool. In the first article, we examined the energy study and how the tablet can facilitate tasks such as annotating existing documents, taking notes, and storing and accessing documents.
A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability. Some tips from an array of manufacturers’ reps round out this useful investigation.
