<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman","serif";color:black">A project I’m building the energy model for is considering switching to electric heat. I understand that generally you would use the predominant HVAC system,
so if the “predominant” system is electric, you would use System 8. See highlighted excerpt below.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman","serif";color:black">My question to you is: what qualifies as “predominant”? Is there some percentage of energy consumption assigned to gas and electricity that signifies either
