<TITLE>Residential Internal Gains in IECC 2006</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/rtf format -->
<P><FONT SIZE=2 FACE="Arial">Does anyone know the history of the internal gain equation that is included in Table 404.5.2 in Section 404 (Residential Performance Approach) of IECC 2006. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">Using it a 3 bedroom 2,000 square foot house would have a total daily internal gain of 77,812 BTU which would be equivalent to 22.8 kWh a day (assuming its all electric). I am just trying to get a sense of how reasonable this number is. I do realize it is supposed to represent all internal gains including lighting. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">Thanks in advance for any help.</FONT>
