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).

Is it acceptable to model a split-type AC with inverter technology compressor as a heat pump, like modeling VRF?

A portion of our building envelope is historic. Can we exclude it from our model?

Our project has a large process load—75%. Despite our efforts to make an efficient HVAC design, the cost savings are minimal. What can we do to earn this prerequisite and be eligible for LEED certification? Is there any flexibility in how we model the p

Our process load is higher than 25%. Do we have to justify that?

Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?
