    <div class="moz-cite-prefix">You're right, Bill, my 0.5 in. H2O was
      too low, but we use very small fans all the time in residential
      installations that run lower than that.š So when I do a LEED or
      90.1 or CA T-24, I know the fan power is lower than the motor
      nameplate, but I have trouble getting the small fan manufacturers
      to even know what fan efficiency is...š Alas...<br>
      <br>
      I really appreciate the reference to mechanical efficiency in the
      ASHRAE Pocket Guide.š I'm going to go after that now.<br>
      <br>
      <br>
      Thanks again for your thoughts and insight.<br>

            apologize for confusing motor efficiency with fan mechanical
            efficiency. Since section 6.5.3.1 describes the maximum
            allowable fan power, we can expect it to use conservative
            allowances for mechanical efficiency and static pressure.
            Using the allowance for bhp (bhp ˜ CFM<sub>S</sub>*0.00094 +
            A) and neglecting the pressure drop adjustments (A), we can
            determine static pressures (SP) for a range of mechanical
            efficiencies by setting 0.00094 = SP/(6356xefficiency).
            Using a range of mechanical efficiencies from 0.4 to 0.6
            (ASHRAE Pocket Guide, 7<sup>th</sup> ed. p. 246), we get a
            range of static pressures from 2.4” to 3.6” w.g. That’s
            higher than your 0.5”, but seems reasonable to me for

            <br>
            I verified that the references you gave lead to the result
            of the calculation in the spreadsheet, but if the
            theoretical calculation below has any validity at all, the
            assumed fan efficiency in 90.1 is about 8%.š I used a fan
            static pressure rise of .5 in. H2O.š <br>
            <br>
            So, this fan efficiency seems a little low to me.<br>
            <br>
            You said "Fan efficiency is from ASHRAE 90.1, Table 10.8 as
            described in G3.1.2.9." but Table 10.8 is Fan Motor
            efficiency, which is about 85%.š I have no problem with
            that, but to use the theoretical fan power equation I need
            the Fan efficiency.š Do you have any idea what fan
            efficiency is assumed in 90.1?<br>
            <br>
            I also notice that the fan power calculation in 90.1 does
            not include a pressure rise component, which I find odd.š Is
            the pressure rise across the fan assumed somewhere?š From
            the checks described above, it appears to be about .5 in.
            H2O.š Does this seem reasonable?<br>

              <br>
              The theoretical fan power equation, Fan BHP = (cfm x
              static press "w.c.) / (6356 x fan efficiency) can be used

              efficiency.š This seems to be NOT the way the BHP is being
              calculated by the spreadsheet that was attached
              previously.<br>
              <br>
              Is there a reason for that?<br>
              <br>
              Was there an assumed fan efficiency used in the
              spreadsheet, and was it based on anything particular, or
              just a conservative assumption?<br>
