	Sec. 2311.002.  COMBINED HEATING AND POWER SYSTEMS.  When 
constructing or extensively renovating a critical governmental 
facility or replacing major heating, ventilation, and 
air-conditioning equipment for a critical governmental facility, 
the entity with charge and control of the facility shall evaluate 
whether equipping the facility with a combined heating and power 
system would result in expected energy savings that would exceed 
the expected costs of purchasing, operating, and maintaining the 
system over a 20-year period.  Notwithstanding Chapter 2302, the 
entity may equip the facility with a combined heating and power 
system if the expected energy savings exceed the expected costs.
