whichever is less.
4. The maximum height of any roof-mounted
accessory wind energy system is 15 feet
above the height of such structure. Roof-
mounted systems are not included in the
calculation of maximum structure height.
5. Roof-mounted accessory wind energy
systems shall be set back from any edge of
the building upon which they are mounted
by a distance equal to or greater than the
total height of the system, measured from
the roof surface at the point of attachment
to the top of the system at maximum
vertical rotation. The setback distance shall
be measured to the center of the wind
