To quantify and make public the energy system’s conversion efficiency.
Calculate the project’s system energy efficiency coefficient (SEEC), benchmark SEEC, and percentage improvement above the benchmark based on the project’s nonrenewable energy sources, using the following formula:
Total energy delivered to customers (MMBtu) = CL + HL + EL
CL = Annual cooling load delivered to all customers (MMBtu)
- Convert tons of cooling to MMBtu using a conversion factor of 0.012 (MMBtu/ton-hr)
HL = Annual heating load delivered to all customers (MMBtu)
EL = Annual electric load delivered to all customers (MMBtu)
- Convert MWh of electricity to MMBtu using a conversion factor of 3.412 (MMBtu/MWh)
Additionally, establish a public disclosure policy to publish the results of SEEC evaluations in the project’s annual performance and/or sustainability reports.
Projects that own or operate local generation units (including backup generation) must have in place formal processes and/or infrastructure to enable periodic monitoring of the energy system conversion performance of electricity generation, cooling units, and heating units.
