My proposed model is showing fan energy far in excess of the baseline. The Baseline systems is PVAVS Dx Cooling with HW reheat– The proposed is PVVT with Water Source Heat Pumps. I have attached SS-M and SSL for the Appendix G model and for the proposed, for the system which seems to be the heart of the problem – Sys-1 in the Baseline and ERU-1 in the proposed. I am at a loss to explain why the fans in the proposed seem to be running 1000 hours a year more than the proposed. I am in the process of reducing unmet heating hours in the proposed by adding electric BB but it does not seem to have an effect on the fan run time. I would really appreciate any insights from the community on how I might approach this. <o:p></o:p></p><p class=MsoNormal>Thanks in advance, <o:p></o:p></p><p class=MsoNormal>Gerry Hazel<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Gerard Hazel <o:p></o:p></p><p class=MsoNormal>M&E Engineers, Inc.<o:p></o:p></p><p class=MsoNormal>908-526-5700 x14<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
