“ Each agency will prescribe policies under which its industrial facilities in the aggregate increase energy efficiency by at least 20 percent in fiscal year 2000 in comparison to fiscal year 1985, to the extent that these measures minimize life cycle costs and are cost-effective in accordance with 10 CFR Part 436. Each agency shall establish appropriate indicators of energy efficiency to comply with this section. ”

“ Each agency using petroleum products for facilities operations or building purposes shall seek to minimize such use through switching to an alternative energy source if it is estimated to minimize life cycle costs and which will not violate Federal, State, or local clean air standards. ”

“ To the extent practicable, each agency shall require vendors of goods to provide appropriate data that can be used to assess the life cycle costs of each good or product, including building energy system components, lighting systems, office equipment, and other energy using equipment. ”
