### TRIAL STANDARD LEVEL S AND EQUATIONS Trial Standard Level Selection Criteria DOE defined f ive Trial Standard Levels ( TSLs ) for this Notice of Data Availability ( NODA ) , as described below. 1. TSL 5 represents the maximum technologically feasible ( max - tech ) level . 2. TSL 4 is an intermediate step between TSL 5 ( the max - tech level ) and TSL 3 ( the maximum c ustomer net present value ( NPV ) level based on a 7 - percent discount rate ) , subject to the requirement that the TSL 4 NPV must be positive. Where a sufficient n umber of efficiency levels allow it, TSL 4 is set at least one level below TSL 5 and one level above TSL 3. In some case s , the TSL 4 efficiency level equals the TSL 3 level because the next level had a negative NPV. In cases where the maximum NPV efficienc y level is the penultimate efficiency level and the max - tech level showed a positive NPV , the TSL 4 efficiency level is also the max - tech level. 3. TSL 3 represent s the efficiency level within each equipment class with the highest NPV at a 7 - percent discount rate . 4. TSL 2 represents an intermediate efficiency level between TSL 3 and TSL 1. 5. TSL 1 represents energy use reduction of 10 percent as compared with the current standard or the baseline, except that it is reduced to 0 percent for classes where TSL3 is at 0 percent. DOE analyzed 1 3 equipment classes for the NODA , and produced 1 9 cost - efficiency curves . TSLs for the full set of equipment classes have been established by extending results from primary equipment classes to secondary classes that are similar fr om an engineering perspective. Table 1 ( below ) maps the secondary equipment classes to those similar, directly analyzed equipment classes.
