This overstates the energy consumption on the proposed model somewhat but the approach is at least conservative, defensible and simple. Even if the duct system has lots of restrictions and the filters are dirty, you know that the real world energy consumption will be no worse than the motor horsepower. Using this method I've found that the Appendix G fan energy still gives me savings, even though I'm (likely) overstating the proposed consumption. My take is that fan manufacturers are pretty good at matching motor HP and performance to keep equipment costs down.</div><div><br></div><div><div><span class="Apple-style-span" style="font-size: 13px; font-family: Verdana, Helvetica, Arial; ">Steve Samenski, PE, LEED AP BD+C, BEMP</span></div><font face="Verdana, Helvetica, Arial"><font><font size="2"><span style="font-size: 10pt; ">

Do you typically use the nameplate motor HP or do you use the total pressure along with the mechanical and motor efficiencies. Using the nameplate motor HP to get a W/cfm or W/gpm seems to overestimate the fan/pump energy because the next available motor size is chosen (or the motor is oversized). The baseline on the other hand only uses the BHP with the motor efficiency for fan power and a straight W/gpm number for pumps.<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125); font-family: Calibri, sans-serif; "><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125); font-family: Calibri, sans-serif; ">On another note related to fan power, are laboratory exhaust fans (for general and fume hood exhaust) considered part of the “System Fan Power” or are the exhaust fan powers modeled so that the baseline and proposed are kept the same. The exhausted air is made-up via the air handling unit which also serves other non-laboratory spaces and has a return fan. I’ve read some discussions on this forum leaning towards including it as part of total system fan power but I’ve also seen LEED review comments stating that independent exhaust fans should be modeled identically between baseline and proposed models. It seems like keeping the exhaust fan powers the same in both cases helps boost the energy cost savings as the fan power allowance when excluding exhaust fan is distributed to only the supply/return fans.<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125); font-family: Calibri, sans-serif; "><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125); font-family: Calibri, sans-serif; ">Last question is do you break up your baseline total system fan power into supply/return/exhaust using the power or flow fraction of each applicable fan in the proposed design? I typically use the flow fraction but I was checking out the “Energy Model Input Translator” put out by RMI and it seems like they calculate baseline fan power by distributing the total system fan power by power fractions for each fan.<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size: 11pt;
