I'm currently working in a project of a shopping centre (common areas + tenant areas) pursuing LEED certification (Core&Shell).
This shopping center mall is an open-mall type (i.e., outdoor and without HVAC system) with some canopies and shading devices covering roughly 50% of the mall area. This type of mall design has evident environmental advantages against a typical enclosed shopping center mall, namely in what respects energy use, much lower in an open-mall (only lighting) than in a conventional enclosed mall (lighting, climatization and ventilation).
If we model the baseline building mall as an outdoor area, the open-mall center is deeply penalized under EA.P2 and EA.C1 because mall is the only relevant core & shell zone where energy savings can be achieved. As this is a core & shell, shops must be modeled equally in the proposed and the baseline buildings. This does not seem to be fair: as open-air mall, much less energy intensive, being penalized under energy efficiency related LEED credits…
Given this, is it reasonable to model the mal in the baseline building as an enclosed mall ?

There are some CS projects that have no common space lighting. You should be able to get some savings from the outdoor spaces. You can then claim additional savings by requiring the tenants to install lower than the 90.1 allowance via a lease agreement. This is no different than most CS projects.
You cannot compare an indoor space to an outdoor space. The configuration of the baseline must be the same as the proposed design.
