2. Code of Practice on Energy Labeling of Products. Pursuant to Section 15 of the EEC 
Act, the Code of Practice on Energy Labeling of Products (COPE) provides for the 
calculation methods of the following:  
 
2.1 The Air Conditioner Energy Efficiency Performance Rating (EEPR) or the star rating 
shown in the DOE Energy Label is based on the Cooling Seasonal Performance 
Factor (CSPF) , which is calculated as foll ows: 
 
CSPF =          Cooling Seasonal Total Load (kWh )   
         Cooling Seasonal Energy Consumption (kWh)  
 
Where:  
 
CSTL  stands for Cooling Seasonal Total Load and is defined as the total annual 
amount of heat energy removed from the indoor air when the equipment is operated 
for cooling in active mode. The value of which must be converted and expressed in 
kilowatt -hour (kWh ). 
 
CSEC  stands for Cooling Seasonal Energy Consumption and is defined as the total 
annual amount of electrical energy consumed by the equipment when it is operated 
for cooling in active mode and is expressed in kilowatt -hour (kWh) . 
 
The EEPR reflected on the DOE Energy Label shall correspond to the CSPF value 
shown in the product test report during product registration. The EEPR shall be 
adjusted accordingly (as needed) once the product has undergone verification 
testing.  
 
2.2 For the estimation of monthly ene rgy kWh consumption  (based on a specified 
hour of daily usage), as shown in the DOE Energy Label, the calculation is as follows:  
 
Monthly kWh Consumption = Power Input x Daily Operating Hours x 30 x F  
 
Where:   
 
Power Input  is the determined electrical power required by the equipment to operate 
normally and is expressed in kilowatts (kW). This corresponds to the value declared 
by the applicant during product registration.  
 
Operating Hours  is the assumed length of time that the equipment is operated in a 
day and is expressed in hours. With regards to the DOE Energy Label, this parameter 
is assumed to be 9 hours.  
 
F is the assumed operating factor for the air conditioners. It is 0.8 for fixed -speed 
units (due to compressor cut in / off) and 0.5 for variable -speed units (due to speed 
adjustment / control).     PELP – IMPLEMENTING GUIDELINES FOR AIR CONDITIONERS                               Page 7 of 8 
  
2.3 For the estimation of monthly electricity cost , the calcu lation is as follows:  
 
Monthly Electricity Cost = Monthly kWh Consumption x Electricity Price  
 
Where:   
 
Electricity Price  is the prevailing peso per kWh, as indicated in the electricity bill 
issued by an electric power distribution company.  
 
2.4 For the estimation of  monthly Greenhouse Gas (GHG) emission  due to monthly 
electricity consumption, the calculation is as follows:  
 
Monthly GHG emission = Monthly kWh Consumption x Emission Factor  
 
Where:  
 
Emission Factor  is the Simple Operating Margin (OM) Emission Factor derived 
using the power grid statistics and is available in the DOE Website.   
   
The unit of the calculated GHG emission shall be in kg CO 2.
