Projects of a certain scope can simply take a while, and such is the case with this medical complex. We check in seven years after the site evaluation but still a year or two away from opening. It’s a good time to ask some questions: How do you plan for equipment that isn’t invented yet? How do you keep adjusting design once construction has started? Explore the obstacles - plus intricacies, such as how the BAS works with emergency power - that make such planning anything but child’s play.
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.
