Planning & EstimatingQuestion 381 of 521
Under the optional dwelling method, at what percentage is the nameplate rating of the air-conditioning equipment included in the heating/AC portion of the calculation?
a.40%
b.100%
c.65%
d.75%
Explanation
In the optional method, air-conditioning is included at 100% of its nameplate rating (as one of the larger heating/AC selections). The 65% figure applies to certain central electric heating, and 40% is the optional method's general-load factor, not the AC factor.
