Approximations and Sources of Error

1. Assumed complete horizontal mixing of air inside house.
2. The house was equipped with a Coleman Heat Package furnace that, according to the manufacturer, delivered 34,000 Btu/h of heat when operating. Calculations assumed that the furnace performed according to the manufacturer’s specifications; however, the furnace’s age (16 years) may have caused this to be an invalid assumption. We also assumed that when the HOBOs registered the furnace as active, it always worked at maximum output. Data of Mr. Davis's actual average daily electric use indicate 30% less than estimated.
3. External temperature variation during measurement period 1
4. External temperature variation during measurement period 2
5. Temperature measurement variation between duplicate Hobos
6. Major approximations of area and volume
7. Whole house R-Value Approximation
