1. The area of the CI project. 2. The portion of the building included in your model. This could be part of the building or the whole building. See Step 2 on page 169. 1. Usually you will need to model more than just the CI area but it depends on the HVAC system configuration. 2. For building envelop you can use the previous (Table G3.1-5 Baseline (f)). For lighting and HVAC you use ASHRAE baseline.
