<DIV style="FONT-FAMILY: tahoma, sans-serif; COLOR: #000000" class=yiv8184329658gmail_default><BR></DIV>
<DIV style="FONT-FAMILY: tahoma, sans-serif; COLOR: #000000" class=yiv8184329658gmail_default>I'm simulating a large commercial building for <SPAN class=yiv8184329658>LEED</SPAN> compliance. There i am facing a major issue in pumping power annual consumption. The proposed case pumping power is almost 7 times higher than the <SPAN class=yiv8184329658>ASHRAE</SPAN> baseline case which has great impact on my overall anticipated savings. I've generated hourly report to see the pump operations power and found propose case pump is running all year round whereas baseline is running as per building operating hours. I've thoroughly checked all the schedules assigned and it seems fine to me. My gut feeling is there is some load which is driving the pump to run throughout the year. I would appreciate if someone can give expert advice to troubleshoot this.</DIV>
