<P DIR=LTR><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">I am relatively new to eQuest, and trying to analyze the output from one of my models. I am having trouble reconciling two of the reports: BEPS (Building Energy Performance) with LS-E (Space Monthly Load Components).</FONT></SPAN></P>

<P DIR=LTR><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">My model only has 3 spaces, and the total</FONT></SPAN><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"> <FONT SIZE=2 FACE="Arial">annual</FONT></SPAN><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"> <FONT SIZE=2 FACE="Arial">heating load for the three spaces is: 62.240 + 34.887</FONT></SPAN><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial"> + 66.305 = 163.432 MBTU.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">However, the BEPS report shows a total heating fuel use for Natural Gas of 113.0 MBTU.</FONT></SPAN></P>

<P DIR=LTR><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">The fuel number should actually be</FONT></SPAN><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"><U> <FONT SIZE=2 FACE="Arial">larger</FONT></U></SPAN><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial"> than the sum of the heating load, since there is some loss of energy in the conversion of the fuel to heat. In this case, there is</FONT></SPAN><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"> <FONT SIZE=2 FACE="Arial">actually</FONT></SPAN><SPAN LANG="en-us"></SPAN><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial"> a smaller amount of BTUs in the fuel for the overall building.</FONT></SPAN></P>
