DOE解读IES LM79,LM80和TM21的差异

TM-21 Calculation Verification

?The method is provided as formulas and procedure?This can be easily

developed in spreadsheet or similar common software tools

….but calculations can be easily miss-coded?A verification example –data + calculation results is provided to allow

checking of process and results

How Will TM-21 be Applied

?TM-21 may be adopted by organizations/programs as documentation of performance (i.e. Energy Star)

–Program may define who does calculations (lab, manuf, other)–Program could do calculations themselves

?TM-21 may be requested as part of LM-80 testing

–Test lab will need to develop calculation sheet

?TM-21 may be applied by a manufacturer

–Oversight/random checking of calculations will be prudent

It is likely that TM-21 will achieve widespread adoption and use
