A. Insulation. The owner of residential housing subject to the provisions of this chapter shall be required to install all of the insulation necessary to comply with the standard set forth in section 16.60.100.A., above, without regard to the cost of such compliance.
B. Additional energy conservation measures.
1. An owner shall not be required to install any additional energy conservation when the required insulation has been installed within the 42 month period immediately preceding the sale, exchange, or transfer of the property and the cost of installing the insulation was $800 or more for a detached, single family residence, or $560 or more per dwelling unit for residential housing consisting of two or more units.
2. An owner shall be required to install additional energy conservation measures when any of the following apply:
a. The required insulation is present and was installed prior to the 42 month period preceding the sale, exchange or transfer;
b. The insulation is not required because the attic of a building has a headroom of less than 30 inches at the attic peak; or
c. The required insulation was installed within the 42 month period preceding the sale, exchange, or transfer, at a cost of less than $800 for a detached, single family residence, or less than $560 per dwelling unit for residential housing consisting of two or more units.
3. Priority of additional energy conservation measures. The additional energy conservation measures to be installed shall be those set forth in section 16.60.100.B, and they shall be installed in the order listed in that section unless a different priority is approved by the building official. The building official may approve implementation in a different priority when it is determined that doing so would achieve better overall energy conservation or that the implementation of one or more of the items listed in section 16.60.100.B would not be feasible.
4. Maximum expenditure. When the installation of additional energy conservation measures is required pursuant to paragraphs B.2.a or B.2.b of this section, the maximum amount that an owner shall be required to spend on additional energy conservation measures shall be $800 for a detached, single family residence, or $560 per dwelling unit for residential housing consisting of two or more units. When the installation of additional energy conservation measures is required pursuant to paragraph B.2.c of this section, the maximum amount that an owner shall be required to spend on additional energy conservation measures shall be the difference between $800 and the cost of installing the required insulation for a detached, single family residence, or the difference between $560 per dwelling unit and the cost of installing the required insulation for residential housing consisting of two or more units. The cost of the installation of any of the additional energy conservation items listed in section 16.60.100.B. which occurred during the 42 months preceding the sale, exchange, or transfer shall count toward meeting this requirement.
C. Credit for energy conservation measures not listed in section 16.60.100.B. The building official may grant an owner a credit toward some or all of the additional energy conservation measures listed in section 16.60.100.B that would otherwise be required to be installed upon the owner providing the building official with documentation that the owner has made other improvements to the building, or buildings, which resulted in a documented energy or water savings and that such improvements were installed within the ten year period immediately preceding the sale, exchange, or transfer of the property. Examples of the types of improvements for which such credits may be granted include, but are not limited to, replacement of single with dual pane windows or the replacement of HVAC or water heater systems with more efficient systems.
