thermal blocks & HVAC zones

Hello, I´ve a question about thermal zonification in my energetic model. I use Energy+ and my proposed HVAC system is Geothermal Heat Pump, AHUs for ventilation requeriments, Fan-Coils and Radiant floor (all supply by GHP). To model HVAC system, i have to separate all HVAC zones in thermal blocks differents. So, if i want to model a thermostat for each thermal block, i have to model a AHU for each thermal block. I don´t have to model 4 AHUs like my proposed design. Thank you very much. Best regards

You are supposed to model the proposed case as designed/built (Table G3.1-1 Proposed). You do have some latitude to group like thermal blocks to simplify your model (see Table G3.1-7 Proposed).
