Section 4-222 - Solar Energy Project

(a)    A project qualifies as a solar energy project if it:
        (1)    is an addition, alteration, or improvement to a residential building or a commercial building; and
        (2)    is designed to reduce the energy requirements of the building by using:
            (i)    wind energy;
            (ii)    energy from a wood-burning appliance; or
            (iii)    solar energy of:
                1.    the active type based on mechanically forced energy transfer;
                2.    the passive type based on convective, conductive, or radiant energy transfer; or
                3.    a combination of these types.
    (b)    A solar energy project may include:
        (1)    a solar process heat device;
        (2)    a solar electric device; and
        (3)    an earth–sheltered building in which the sheltering substantially reduces the consumption of energy by the building.
    (c)    A solar energy project may not include a fireplace, unless the fireplace is an integral part of a system designed to use passive solar energy.
