7. SCE Testing

8. ASHRAE Standard 207P Title: Purpose: Scope:
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

10. DOE/CBEA 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.
