2-10.4.2 This manual provides specific guidance in key areas regarding energy
efficiency studies. Refer to the following paragraphs for additional informati on.
Paragraph 6-3--sizing wiring for increased energy savings is discussed.
Paragraph 7-1-- minimum motor efficiency requirements are provided.
Paragraph 7-3--ASDs are described, including analysis methods to assess energy
Appendix C--design issues relating to power factor correction are discussed.
Appendix F--energy efficiency criteria related to lighting systems are covered in
LIFE-CYCLE COST ANALYSIS .
Include a life-cycle cost analysis in the comparison of design alternative s.
The expected equipment operating life must be based on an engineering assessment of
the realistic operational life. Do not use equipment warranty periods as the expected
service life unless the manufacturer provides convincing evidence that the equipment is
capable of this operational life.
