is usually not required for an energy model, including LEED models. This is the
responsibility of the mechanical designer. Unless I know that a project is
pursuing LEED IEQc2 credit, or that a proposed mechanical design is using
excessive ventilation for some other reason, I will use the proposed design
ventilation rates in both the proposed and baseline models, which I have been
entering on a zone-by-zone basis to this point to meet my interpretation of the

conclusion was that the current requirements are that the baseline and proposed
design models should have the same ventilation rates, BUT that this doesn't
make that much sense as you could over-ventilate to the point where there is no
added benefit to the occupants, and major additional energy use. The
discussion was primarily around LEED EA Credit 1, and there was some
correspondence between the simulation group and the LEED credit chair. I
believe that they will be looking at modifying this requirement for LEED models
