Hi all, this is my first post on the forum. I am a junior mechanical engineer and would appreciate if someone could clarify a problem I'm trying to logically think out.
I am currently using a building energy simulation software Virtual Environment from IES Ltd to run compliance check for CO2 production (Part L2 England & Wales Building Regulations).
The building has been modelled by a drafts person and they have created the internal space (which would be the occupied space to have HVAC) by including both ceiling and floor void as part of the space. Therefore the height of the room is 4.5 meters rather than 2.7 meters. I believe that the ceiling and the floor void should have been modelled in different zones.
What I would like to know is, would a larger room volume affect the energy consumption of the HVAC system? I have thought this out logically and my theory is that a smaller volume of air would mean that less energy is used to either heat or cool than a larger volume of air. Would anyone know how to calculate this?
