''Energy conservation'', shall include but not be limited to the modification of or change in the operation of real or personal property in a manner likely to improve the efficiency of energy use, and shall include energy conservation measures and any process to audit or identify and specify energy and cost savings.

''Energy conservation measures'', measures involving modifications of maintenance and operating procedures of a building or facility and installations therein, which are designed to reduce energy consumption in such building or facility, or the installation or modification of an installation in a building or facility which is primarily intended to reduce energy consumption.

''Energy conservation projects'', projects to promote energy conservation, including but not limited to energy conserving modification to windows and doors; caulking and weatherstripping; insulation, automatic energy control systems; hot water systems; equipment required to operate variable steam, hydraulic and ventilating systems; plant and distribution system modifications, including replacement of burners, furnaces or boilers; devices for modifying fuel openings; electrical or mechanical furnace ignition systems; utility plant system conversions; replacement or modification of lighting fixtures; energy recovery systems; on-site electrical generation equipment using new renewable generating sources as defined in section 11F; and cogeneration systems.

''Energy management services'', a program of services, including energy audits, energy conservation measures, energy conservation projects or a combination thereof, and building maintenance and financing services, primarily intended to reduce the cost of energy and water in operating buildings, which may be paid for, in whole or in part, by cost savings attributable to a reduction in energy and water consumption which result from such services.

''Energy savings'', a measured reduction in fuel, energy, operating or maintenance costs resulting from the implementation of energy conservation measures or projects; provided, however, that any payback analysis to evaluate the energy savings of a geothermal energy system to provide heating, cooling or water heating over its expected lifespan shall include gas and electric consumption savings, maintenance savings and shall use an average escalation rate based on the most recent information for gas and electric rates compiled by the Energy Information Administration of the United States Department of Energy.

''Local governmental body'', a city, town, district, regional school district or county, or an agency or authority thereof, including a housing authority, board, commission, department or instrumentality of a city, town district, regional school district or county, and any other agency which is not a state agency or building authority; or a combination of 2 or more such cities, towns, districts, regional school districts or counties, or agencies or authorities thereof.

''Marine or hydrokinetic energy'', electrical energy from: (a) waves, tides and currents in oceans, estuaries and tidal areas; (b) free-flowing water in rivers, lakes and streams; (c) free-flowing water in man-made channels; or (d) differentials in ocean temperature, called ocean thermal energy conversion.

''Minor informalities'', minor deviations, insignificant mistakes and matters of form rather than substance of the proposal or contract document which may be waived or corrected without prejudice to other offerors, potential offerors or the public agency.

''Non-renewable energy supply and resource development'', shall include but not be limited to gasoline, natural gas, coal, nuclear energy, offshore and onshore petroleum, and facilities related to the exploration, development, processing, transportation and distribution of such resources and programs established for the allocation of supplies of such resources and the development of supply shortage contingency plans.

''Person'', any natural person, business, partnership, corporation, union, committee, club, or other organization, entity or group of individuals.
