"If ASHRAEIIES Standard 90.1, ... is amended with respect to any ... 

equipment, ... the Secretary shall establish an amended uniform 

national standard ... at the minimum level ... specified in the amended 

ASHRAE/IES Standard 90.1, unless the Secretary determines, by rule 

... supported by clear and convincing evidence, that adoption of a 

uniform national standard more stringent than such ... would result in 

significant additional conservation of energy and is technologically 

feasible and economically justified."
