§4–808.

    (a)    To determine life-cycle costs, the Department, in cooperation with the Maryland Energy Administration, shall establish standards that require at least:

        (1)    an evaluation of:

            (i)    the amount and type of glass used in the building and the directions of exposure;

            (ii)    the effect of insulation incorporated into the design of the building;

            (iii)    the effect of the use of active and passive solar energy systems;

            (iv)    if wind or solar energy is used, the orientation and integration of the building with respect to its site; and

            (v)    the variable occupancy and operating conditions of the building and its parts;

        (2)    an energy consumption analysis of each major piece of equipment in any of the following systems serving the building:

            (i)    the cooling system;

            (ii)    the heating system;

            (iii)    the hot water system;

            (iv)    the lighting system;

            (v)    the ventilation system; and

            (vi)    any other major energy-using system; and

        (3)    a comparison of possible alternative energy systems:

            (i)    that would use the most plentiful and available energy resources in combinations that would result in maximum energy efficiency, both in the building and at the source; and

            (ii)    with respect to the projected annual energy consumption of the major energy-using equipment of each system over the life of the building.

    (b)    To evaluate life-cycle costs, the Department shall:

        (1)    adopt and uniformly apply a definition of the “life of the building”; and

        (2)    provide defending criteria for the definition adopted.
