For Core and Shell, in the reference guide and various other LEED resources I’ve been looking through - it appears that for LEED-CS projects it’s possible to take 15% of the annual electricity (from energy model), multiply by the two years and 35% to get the required green power purchase. However, the LEED Online template calculator does not take into account the “15%”.

It is unclear how to take into account the 15% given the hidden calculations of the calculator. (You can understand – this makes a HUGE difference in the amount of green power our project purchases - so we want to understand what to do before we make the purchase.)

Your guidance on how to incorporate the 15% is much appreciated!

Thanks,
Melissa
