The Total Energy Use Calculator is a powerful tool that allows individuals and businesses to assess their energy consumption efficiency. It provides a precise measurement of the energy used for lighting and appliances relative to the total floor area. This information is invaluable for making informed decisions about energy consumption and efficiency improvements.
Formula of Total Energy Use Calculator
The formula used by the Total Energy Use Calculator is as follows:
Lighting and Appliance Energy Use (kWh/m²/year) = (Total energy consumption of lighting + Total energy consumption of appliances) / (Total floor area)
This formula takes into account both the total energy used by lighting and appliances and divides it by the total floor area to provide a standardized measurement of energy efficiency.
General Terms Table
| Term | Conversion |
|---|---|
| Kilowatt-hour (kWh) | 1 kWh = 1,000 Watt-hours |
| Square Meter (m²) | 1 m² = 10.764 square feet |
This table will serve as a quick reference guide for users, eliminating the need for manual calculations each time.
Example of Total Energy Use Calculator
Let’s illustrate the application of the Total Energy Use Calculator with an example:
Suppose a residential building has a total energy consumption of 15,000 kWh for lighting and 10,000 kWh for appliances. The total floor area of the building is 500 square meters.
Using the formula:
Energy Use = (15,000 kWh + 10,000 kWh) / 500 m² = 50 kWh/m²/year
This means that the energy use for this building is 50 kWh per square meter per year.
Most Common FAQs
To measure the total energy consumption, you’ll need to refer to your energy bills or use energy monitoring devices. These tools provide accurate readings of the energy consumed by lighting and appliances.
Calculating energy use per square meter provides a standardized metric for comparing energy efficiency across different spaces. It helps identify areas for improvement and ensures fair comparisons between buildings of varying sizes.
