<p class="MsoNormal">I often get unmet heating and/or cooling hours in Build 7175, though I get the impression that my DOE2.3 models generally have fewer unmet hours than my DOE2.2 models did, probably due to simulation engine improvements but also due to me
being older and in some ways, wiser. <span style="font-family:"Segoe UI Emoji",sans-serif">
