In LEED energy savings seem to be calculated not only as an energy unit amount, but also and more specifically in EAc1 and 2 in monetary amounts. As solar PV panels would contribute to savings in kWh the calculation for EAc2 would provide one number using this as the basis, but in the EU most countries have feed-in-tarriffs, which reimburse the owner for energy produced at a higher rate than the cost of energy. This would therefore provide a more favorable calculation for EAc2 when "using the building's annual energy cost". Does anyone know if feed-in-tarriffs can be used in the calculation?

Use the energy cost of electricity bought from a utility on site, not the feed-in tariff rate for EAc1 and EAc2 calculations
