The value shall be retained with 2 decimal places (at least 3 decimal places when used as a process parameter). 3.2 cooling seasonal total energy; CSTE total electric energy consumed by the package during cooling operation in the cooling season Note: The unit is kilowatt-hour (kW·h). The value shall be retained with 2 decimal places (at least 3 decimal places when used as a process parameter). 3.3 cooling seasonal performance factor; CSPF ratio of the total heat removed from the interior to the total electric energy consumed by the package during cooling operation in the cooling season Note: The unit is kilowatt-hour per kilowatt-hour [(kW·h)/(kW·h)]. The value shall be retained with 2 decimal places (at least 3 decimal places when used as a process parameter). 3.4 heating seasonal total load; HSTL total heat delivered to the interior of a building by the package during heating operation in the heating season Note: The unit is kilowatt-hour (kW·h). The value shall be retained with 2 decimal places (at least 3 decimal places when used as a process parameter). 3.5 heating seasonal total energy; HSTE total electric energy consumed by the package during heating operation in the heating season Note: The unit is kilowatt-hour (kW·h). The value shall be retained with 2 decimal places (at least 3 decimal places when used as a process parameter). 3.6 heating seasonal performance factor; HSPF ratio of the total heat delivered to the interior to the total electric energy consumed by the package during heating operation in the heating season Note: The unit is kilowatt-hour per kilowatt-hour [(kW·h)/(kW·h)]. The value shall be retained with 2 decimal places (at least 3 decimal places when used as a process parameter). 3.7 annual performance factor; APF ratio of the sum of heat removed from the interior during cooling and heat delivered to the interior during heating to the total electric energy consumed by the package over a year consisting of one consecutive cooling season and one heating season Note: The unit is kilowatt-hour per kilowatt-hour [(kW·h)/(kW·h)]. The value shall be retained with 2 decimal places (at least 3 decimal places when used as a process parameter). 3.8 useful water temperature Tm minimum water temperature that contributes to the useful energy content when water is drawn off in the water use model Note: The unit is degree Celsius (°C). 3.9 useful water flow f
