Mont. Admin. R. 42.4.105 - STANDARD COMPONENTS AND PASSIVE SOLAR SYSTEMS
(1) Energy generating systems or their
components that are standard components of conventional buildings do not
qualify for the alternative energy system credit. The department is authorized
to adopt rules defining standard components of conventional buildings and to
establish other necessary elements of passive solar systems.
(2) Passive solar energy systems, or the
components of those systems that have been determined to be acceptable include:
(a) solar greenhouses, sun porches, and like
structures that are properly situated, constructed, and ducted to the building
for which they provide energy to be reasonably considered a complete or
supplementary energy source for that building;
(b) components of a building that have been
altered for energy collection, storage, or distribution to benefit the rest of
the building, such as the addition of triple glazed windows to enclosed
porches;
(c) windows installed in
excess of "double-glazing;"
(d)
thermal collection masses such as brick, stonework, and other types that were
not present in the original structure and were not installed for a purpose
other than energy storage; and
(e)
the components of an envelope house necessary for energy generation and
distribution in the "envelope house," such as the "envelope" area devoted
solely to energy collection, storage, and distribution.
