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

Hey All, This question is basically for the energy modelers out there who use HAP or any other software. I have a conditioned lobby where the fan coil just uses the return air, according to our calculations the door can provide enough OA CFM for ventilation. However, I am not sure if I should input the value of the required CFM in HAP or just leave the OA CFM blank there since it will not be conditioned.

You will need to model the outside air. You need to model it either through the unit or as extra air infiltration. As far as HAP goes you might ask them or post this question on the HAP Users listserve at onebuilding.org
