so my research model should test several things, one of them is wheather the presence of a garage will effect the eui for heating and cooling only, so for some scenarios it will be there for others it wont, and there is a variable no of floors so variable number of zones. How can i effectivly remove the garage frm the results effectively without comprimising the results?

Use the HB Set Multiplier component. It has an option for excl_flr_ which causes the room floor are to be discounted from the EnergyPlus EUI calculation.

Thank you so much Chris, I just want to double check smth, that this component will remove both the area, and the energy use for the garage; as this was written in its source code
" excl_floor_: Boolean to indicate whether the floor area of the room is excluded from the Model it is a part of. Note that this will not affect the floor_area property of this Room but it will ensure the Room’s floor area is excluded from any calculations when the Room is part of a Model and when it is simulated in EnergyPlus’‘’
also is this how it should be connected in gh

No, the only way to remove energy use of something in an EnergyPlus simulation is just to remove all lighting, equipment, HVAC, etc. from it. If you want to do this, you can use the HB Plenum component, which removes all internal energy usage of the room while also excluding the room’s floor area from the EUI calculation. This is the way that I recommend things like crawl spaces be modeled.
However, unconditioned and intermittently-occupied spaces like garages still have lights that are connected to the main building meter and therefore contribute to the building’s EUI (even though you do not count their floor area). So the way that I would model a garage is with the Multiplier component and, yes, you have connected it correctly.

thank yu so much chriss this is what i needed! as i am only researching the energy use for heating and cooling loads so this would be perfect.
