Hello friends,<br><br>Anyone know what the BASELINE system should be if the design system is a ground source heat pump? I have a non-residential building, 3 floors and < 75,000 square feet. The design system type is groundsource heat pump, which leads to system 4-PSZ-HP, which nobody would ever choose for this climate (Burlington, VT).<br>
<br>Any thoughts?<br><br>~Karen~<br>
