Efficiency Rating type:
select energy factor or uniform energy factor, if unknown, select
energy factor
If the Energy Factor radio button was selected, then select User
specified to enter the assessed Energy Factor. Alternatively,
select Standby to enter the efficiency by Standby Heat Loss,
Thermal Efficiency and Input Capacity. Data must be entered
into all three of these fields to define the efficiency by standby

heat loss unless the Energy Source is Electricity. In that case, the
Thermal Efficiency is automatically set to 98%. If the efficiency is
unknown, use the HOT2000 default.
For heat pump water heaters only integrated heat pump water
heaters located inside building envelope can be modelled in
H2K
Do not use Tankless heat pump or Heat pump for modelling
integrated heat pump water heater HPWH energy factor 0.9
HP COP= HPWH EF/0.9

-EnerGuide Rating : assessed using standard operation
conditions. Measured in GJ per year. EnerGuide Rating= Annual
energy consumption (-) On-site renewable energy contributions
- House Address
- Data collected: the date the evaluation was completed
- File number
- Evaluated by
- EnerGuide Rating scale
- Rated Annual energy consumption
- Energy Sources
- On-site renewable energy contributions

- Breakdown of rated annual energy consumption
- Rated energy intensity: Rated annual energy consumption
divided by heated floor area. It allows you to compare the
annual energy use of homes of different
sizes on a "per square metre" basis.
- Rated GHG emissions
- Significant Energy uses not included in rating
- Quality Assured by
