[BLDG-SIM] Residential Internal Gains in IECC 2006

Mike. 

We've checked this against meas data and it is not far from the total loads we've seen. This is documented in several reports on our web site.

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.  

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.   

Thanks in advance for any help.
