My question is about retail space and EAp2/EAc1. According to page xxiii of the Reference Guide, up to 10% of the floor area can be exempted from all credits (except EQp2) for multitenant buildings. However, Energy Star indicates that retail spaces that directly support the main activity of the building should be included under the "Office" space use type (see: http://www.energystar.gov/index.cfm?c=eligibility.bus_portfoliomanager_e...) in Portfolio Manager. How do these two guidelines fit together? Under what circumstances can I exclude a retail space from EAp2/EAc1?
