; and (B) ensure that procurements after the date of enactment of the BRIGHT Act of lighting systems or the individual components of lighting systems maximize life-cycle cost effectiveness and energy efficiency. (2) Use Each public building constructed, altered, acquired, or leased by the Administrator shall be equipped, to the maximum extent practicable as determined by the Administrator, with the most life-cycle cost effective and energy efficient lighting systems for each application. (c) Maintenance of public buildings Each individual component of a lighting system, including a lamp or fixture, that is replaced by the Administrator in the normal course of maintenance of public buildings shall be replaced, to the maximum extent practicable, with the most life-cycle cost effective and energy efficient lighting system possible for the application. (d) Considerations (1) Contracting options In carrying out this section, the Administrator shall consider appropriate contracting options for the procurement of the most life-cycle cost effective and energy efficient lighting systems. (2) Procurement and use In making a determination under this section concerning the practicability of procuring and installing the most life-cycle cost effective and energy efficient lighting system, the Administrator shall consider— (A) the compatibility of the lighting system with existing equipment, including consideration of a cost effective retrofit; (B) whether procurement and use of the lighting system could result in interference with productivity; (C) the aesthetics relating to the use of the lighting system; and (D) such other factors as the Administrator determines to be appropriate. (e) Life-Cycle cost effective The Administrator shall use the procedures and methods established under section 544(a) of the National Energy Conservation Policy Act ( 42 U.S.C. 8254(a) ) in determining whether a lighting system is life-cycle cost effective.
