SCE Testing
ASHRAE Standard 207P
 Title:
 Laboratory Method of Test of Fault Detection and Diagnostics Applied to Commercial
Air-Cooled Packaged Systems
 Purpose:
 This standard provides a method to define an FDD tool’s function. This standard also
provides a method of laboratory test for the performance of Fault Detection and
Diagnostic (FDD) tools on commercial air-cooled packaged equipment.
 Scope:
 2.1 This standard applies to commercial air-cooled packaged air conditioning systems.
 2.2 The test is a physical laboratory test on a particular combination of diagnostic tool for
each model of a unitary system.
 2.3 This standard applies to any on-board, after-market or hand-held hardware and/or
software functionality that detects and/or diagnoses problems that lead to degraded
performance such as, energy efficiency, capacity, increased maintenance costs or
shortened equipment life.
 First Meeting January 23, 8am-12pm (CST), in Chicago

 October 4, 2011 - 12:02pm
Washington, D.C. –
 “The U.S. Department of Energy (DOE) today
announced that it has received the first official
submission by a manufacturer to a voluntary challenge
for a new generation of high-efficiency cost-effective
air conditioners for commercial buildings.
 “The Department will begin testing the new Daikin
McQuay “Rebel” unit from McQuay International to
determine whether it meets the high energy-efficiency
performance levels outlined by the challenge.
