Refer to January 2010 B2B for an introduction to energy auditing and energy retrocommissioning. A good guideline for implementing an energy audit is the ASHRAE Procedures for Commercial Building Energy Audits manual.
Helpful HintsRefer to the October 2006 "HVACR Designer Tips" and "Back to Basics," and this month's "HVACR Designer Tips" for additional information. Design Phase Give proper consideration to adequate duct
When designing an energy conservation system, it is important to be able to collect the operating data so that actual ROI can be monitored and measured against the estimated ROI. The design engineer needs to work closely with the facility engineer to determine what metering and control components are required in order for the facility engineer to do his job efficiently. The same can be said for specifying the expansion of an existing CMMS system so that planned maintenance workorders are available on day one of occupancy.
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.
