<div>The above paper might have the answer for you (page 35). Let me know if it works out. I have not really tried it.</div>

<div>This question is about setting the efficiency of the budget case domestic hot water heater for modelling purposes. In 90.1-2004, Section 11.3.2 (b) is states "<font face="Times New Roman, Times">All HVAC and service water heating equipment in the <i>budget building </i>shall be modeled at the minimum <i>efficiency </i>levels, both part load and full load, in accordance with 6.4 and 7.4. <br>
<br></font>7.4 refers to Table 7.8. A small gas heated storage tank has an efficiency of 0.62-0.0019V EF. Where EF is the energy factor. From what I can find there is no single formula to convert EF to thermal efficiency. So what would you model the budget case efficiency at in DOE2.1e for this example?<br>
<br>Thanks for any insight you can give.<br><font color="#888888"><br><br><br><br><br><br>
