● Section 151<br />
● Revise & Add: language to read as follows:<br />
● “Domestic <strong>Water</strong>-heating systems. <strong>Water</strong> heating systems shall meet the<br />
requirements of either A, B, C or D and meet the requirements of E and F or<br />
shall meet the requirements of Section 151(b)1.<br />
● D. For systems serving individual dwelling units using Package C, an electricresistance<br />
water heater may be installed as the main water heating source, only<br />
if the water heater is located within the building envelope and the minimum<br />
percent of the energy for water heating is provided by a passive or active solar<br />
system as specified in Table 151-B COMPONENT Package C<br />
● Table 151-B COMPONENT Package C<br />
● Remove: Footnote 7 from table and below text: “Electric-resistance water heating may<br />
be installed as the main water heating source in Package C only if the water heater is<br />
located within the building envelope and a minimum of 25 percent of the energy for<br />
water heating is provided by a passive or active solar system.<br />
● Adjust Climate Zones (see below)<br />
● Add to “<strong>Water</strong> <strong>Heating</strong>” section, an additional sub-row and include “If electricresistance,<br />
<strong>Solar</strong> Fraction = (See below),” and remove “or section 151 (b)1”<br />
