##### Monthly Heat Pump Efficiency
This graph shows the efficiency of the heat pump in each month. Heat Pump
efficiency is measured as "COP"(Coefficient of Performance). A COP of 2.5
means 250% efficient, as compared to electric resistance heat, which is 100%
efficient. The heat pump's efficiency improves as the temperature outside
warms.

##### Design Heating Load Information
An approximate estimate of the design space heating load of this building is
**{design_heat_load:,.0f} Btu/hour**, not including any domestic hot water load.
This was based on a Design Outdoor Temperature of **{design_heat_temp:.1f} °F**;
approximately 1% of the hours in the year (88 hours) will be colder than this
temperature. The design heating load figure does *not* include any safety margin
and is measured at the output of the heating system.
The heat pump is estimated to have an output of **{hp_max_capacity_5F:,.0f} Btu/hour at a 5 °F**
outdoor temperature. The heat pump will have different maximum output capacities at other
outdoor temperatures, as the heat pump's efficiency varies with outdoor temperature.
This energy model shows that the heat pump {max_hp_str} point during the year.
