The Home Energy Saver website includes a section called LEARN which offers tips about energy savings, an explanation of the house-as-system energy efficiency approach, and other information to help people understand how energy is used in a home. When launched in 1994, Home Energy Saver was the first and only online home energy calculator.
In newer designs, the timer only runs while the compressor runs, so the longer the refrigerator door is closed, the less time the heater will run for and the more energy is saved. A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more, thereby preventing excessive ...

Households in different parts of the world will have differing levels of consumption, based on latitude and technology.
The energy usage is calculated by considering the all aspects of buildings (location, design, construction, water heating, cooking, ventilation and appliances, lighting etc.) and for dwelling energy rating it use some standard assumptions, such as occupancy scenario, thermostat setting, occupant stay timings.
