The process for an ECP is simple, and an energy assessor will comply with a calculation based on the appliances within the home.  

For example, factors that can contribute to the rating include:  

• •  The type of construction 

• •  The different use of a building

• •  Cooling 

• •  Ventilation

• •  Heating  

• •  Hot water systems used

•  The type of lighting.  

As soon as this is done, the assessor will comply with a calculation and consider further requirements for his survey. Once they have collected all the information, they can enter the information and produce an ECP.
