Hello Marcus. We have a healt care building and I would like to know if my baseline HVAC model approach is correct. The building has 12 floors. So it will classified as system 7 (VAV chiller water with reheat). However floors 9 to 10 are patient rooms. Floors 3 to 8 there are areas that have special presurisation and cross-contamitantion requirements. Floors 1 and 2 are general support areas. My approach is the following Floors 1 and 2 System 7 Floors 3 to 8 system 3 and 4 according to exeption G3.1.1 phragraph c Floors 9 to 12 system 2 -PTHP (residential) Do you think my approach is valid. Thanks.

You may not need to model a system 7 for the first two floors. When you apply exceptions to G3.1.1 the area related to that exception is subtracted from the total. So you applied exceptions a and c. Subtract these from the total area and then use the remaining area and enter Table G3.1.1A.
