<P dir=ltr><SPAN lang=en-us></SPAN><SPAN lang=en-us><FONT size=2 face=Arial>Hello,</FONT></SPAN></P>
<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></SPAN><SPAN lang=en-us></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></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>
<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>If someone understands how this works, please let me know.</FONT></SPAN></P>
