1- Estimate the energy usage breakdown in the building (Energy consumption by end use in percentage) for instance lighting, cooling, space heating, refrigeration, water heating, and ventilation. Access the IEA Commercial Building Consumption Survey to estimate the average annual energy used by square foot for each building component.
2- Estimate the CO2 emissions by kWh. Access this link to estimate the CO2 emissions. www.epa.gov/cleanenergy/energy-resources/calculator
