See quotation from LEED-CI. "Use tenant renewable energy systems to offset the project’s energy cost. Calculate the project’s
percentage of renewable energy by the following equation:
% renewable energy = Equivalent cost of usable energy produced by renewable energy system/ Total building annual energy cost"
If the CS project fulfills the criteria for meeting maximum points on this credit and a lot of photovoltaics are installed, are the tenant obliged to install even more renewable energy sources? This doesn't seem correct.

From the Reference Guide.
Projects whose base building uses renewable energy are eligible to receive credit for the percentage of its contribution. Use Equation 2 to determine this amount.
Equation 2. Equivalent cost of renewable energy from base building system
Equivalent cost of base building renewable energy = ($ value of renewable energy used in base building x % of base building energy delivered to project)
