Topic: The Washington State Facilities Energy Characteristics (PFEC) form is integral part of every ELCCA report.For projects less than 25,000 sf, or where the renovations total less than 50% of the value of the facility, then the PFEC alone suffices to satisfy State of Washington Department of E&A Services energy analysis requirements.Show common data required on the PFEC and NREC forms.Updated

All non-residential building projects in the State of Washington as part of the permitting process need to submit Non-Residential Energy Compliance (NREC) forms. NREC forms are required for mechanical systems, building envelope, and lighting systems.

eQuest is a powerful tool for analyzing envelope options. The following example input screens shows a typical wall section; any material can be varied in composition or thickness, any number of materials can be added or subtracted. Similar screens exist allowing the variation of window, skylight, door & roof options:For the baseline case and each comparative alternative, a lifecycle cost

Topic: What adjustments to the baseline model are required to simulate a displacement ventilation system?Energy Design Resources has a reference for doing underfloor and displacement ventilation systems with eQuest. While useful since eQuest (version 3.61 as of this writing) does not yet natively support displacement ventilation, the information is evidently based on an earlier version of eQuest

Not to be outdone, the folks at Carrier HAP software support also have some recommendations for modeling displacement ventilation systems:1. TRACE has a feature that models the return air plenum as a separate space. This lets you define the size of the plenum and heat going into and out of it. The calculate a load for it as if it was a room and also calculate its temperature. The seem to

The folks at Trane CDS Support have some suggestions for compelling Trace 700 to do displacement ventilation modeling:The air in a space supplied by an underfloor system is stratified and you only need enough airflow to handle the temperature (loads) in the lower stratified region. Trace (as well as the rest of the simulation programs) assumes well mixed spaces with the same temperature at all
