Dear All, My question refers to the LEED Core and Shell modelling guidelines in Appendix 2 of the LEED BD&C guide.
Under the subheading 'tenant spaces' it states that ...'... if the team is pursuing any additional energy saving opportunities not associated with core and shell areas..... outline opportunities....' and then it goes on '... model the electric meters....'
WHat if we are not pursuing any additional saving from the tenant areas...
do we need to model the tenant areas individually
I am modelling a very large shopping center, with many tenant areas - which are like cabins - in a large space of the retail mall . these cabins are also complicated to model as theyare not aligned in straight lines but rather curved and have multiple walls.
Do Appreciate some advice of how exactly to model the tenant areas andinput their loads in a simple way.
Or perhaps not at all, as it will not make a difference to the difference between the proposed and baseline energy costs, as the tenants are modelling with identical inputs to both

The purpose of modeling tenant spaces on different meters in the model is to be able to separate the energy use in those areas from the core areas. You would not need to include each individual tenant space on its own meter in the model. You will need to separate the two in order to claim savings for anything in the core spaces beyond the envelope's impact on HVAC energy use. If you are modeling the tenant spaces identically in both models than just separate the core spaces and the tenant spaces within the model.
So how you model it will depend on where and how you are trying to show energy savings.
