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

CS-2009 EAp2:Minimum Energy Performance

Anticipated Tenant Fit Out

Background: In a C&S building we suggest a Tenant fit out to comply with credit IEQ_c8.2, where we show meeting rooms, corridors and an office space layout resulting in a grater quantity of people of that responding to the "default occupancy". The questions are: 1. Do we have to consider this layout for the PIForms? 2. Do lighting savings have to account for the different spaces like corridors in the lighting power allowed calculations? Thank you

1. I think the default is used in the PIf. 2.If you are trying to claim lighting savings in the tenant space then you must have the actual design that will be used by the tenant or have a requirement in the tenant lease agreement. Corridors within the tenant space would be accounted for in either scenario. For the lease agreement you could use the Building Area Method which is an average for the whole space or the Space-by-Space method which establishes a lighting power density for each portion of the tenant space by space type.

Thank you Marcus, So, as I understand in point 2, if I use the Building Area Method I will not have to consider every different ussage space, which will me allow to take the hole tenant space as "Office" space. I think this option will be better, thank you again

That is certainly the clearer and easier route to take.
