For an existing building, do I need to rotate the model?

Our project has a diesel backup generator. Should we include it in our energy model?

Our project has a large process load—75%. Despite our efforts to make an efficient HVAC design, the cost savings are minimal. What can we do to earn this prerequisite and be eligible for LEED certification? Is there any flexibility in how we model the p

Consider a space, storage, with no heating, modelled with heating setpoint -50 degC, receives air from a central air handling unit VAV system, where the delivered air is pre-conditioned from Outdoor Temp -12 to delivery temp 15. The terminal damper at the zone is set as to deliver the minimum air, but is not programmed to adjust for heating or cooling purposes. In essance I'm left with a space that may be "accidentally" conditioned to a certain degree, but not to hold setpoint of say 20 degC. Per ASHRAE and per LEED, does this space qualifiy as a conditioned space? My gut tells me, no.

I agree with your gut.
