In the Home Energy Saver, users are allowed to select either an electric and gas oven. The following equations describe the method used to calculate energy consumption by ovens. Electric
EC = power x usage_{week} x 52
where:
EC = Annual
energy consumption in kWh
power = energy
consumption rate of the oven (kW)
usage_{week}
= hours of use per week
52 = weeks per
year
For electric ovens, the power consumed is assumed to be
2.3 kW for the purposes of this model (PG&E 1995).
Gas
EC = (oven_rate x usage_{week} x 52) + pilotLight
where:
EC = Annual
energy consumption in therms
oven_rate =
energy consumption rate of the oven (therms/hour)
usage_{week}
= hours of use per week
52 is weeks per
year
pilotLight =
energy consumed by the pilot light (therms/year)
For gas ovens, the energy consumed is assumed to be 0.11
therms/hour and pilot light consumption is 17 therms/year (PG&E 1995). The
default usage for all ovens is assumed to be 2 hours per week, regardless of
oven fuel.
Users are able to alter the inputs for stoves and ovens
only in the detailed inputs model. The table below details the initial assumptions
used for calculating stove and oven energy.
