      1. (i) energy consumption;
      2. (ii) water use; or
      3. (iii) sewage use.

   2. (b) "Energy efficiency measure" includes:

      1. (i) insulation installed in a wall, roof, floor, foundation, or heating and cooling distribution system;
      2. (ii) a storm window or door, multiglazed window or door, heat absorbing or heat reflective glazed and coated window or door system, additional glazing, or reduction in glass area;
      3. (iii) an automatic energy control system;
      4. (iv) a heating, ventilating, or air conditioning and distribution system modification or replacement in a facility;
      5. (v) caulking and weatherstripping;
      6. (vi) a replacement or modification of a lighting fixture to increase the energy efficiency of the lighting system without increasing the overall illumination of a facility unless the increase in illumination is necessary to conform to the applicable building code for the proposed lighting system;
      7. (vii) an energy recovery system;
      8. (viii) a cogeneration system that produces steam or another form of energy for use primarily within a facility;
      9. (ix) a renewable energy or alternate energy system;
      10. (x) a change in operation or maintenance practice;
      11. (xi) a procurement of a low-cost energy supply, including electricity, natural gas, or water;
      12. (xii) an indoor air quality improvement that conforms to applicable building code requirements;
      13. (xiii) a daylighting system;
      14. (xiv) a building operation program that provides cost savings, including computerized energy management and consumption tracking programs or staff and occupant training; or

6. (6) "Qualified energy service provider" means a person who:

   1. (a) has a record of successful energy savings agreements; or

   2. (b) has:

      1. (i) experience in the design, implementation, and installation of energy efficiency measures;
      2. (ii) technical capabilities to ensure that an energy efficient measure generates cost savings; and
      3. (iii) the ability to secure the financing necessary to support the proposed energy efficiency measure.
