When we look into the LEED Reference Guide for Option 1, it seems to require a VAV system which we do not have (see pg. 168). We can show compliance with ASHRAE 90.1 Mandatory requirements but not the modulating air handling units and not the fan static pressure reset, both of which are features inherent with a VAV system. Is there something we're missing that would still allow us to use the Core Performance Guide efficiency requirements and not have to go to the effort and expense of an energy model?
