LEED - Future Expansion = Fan Power Oversizing

2 posts / 0 new

I am working on a project currently that has oversized all of the VAV - AHU fans by approximately 25 HP (was 50 now is 75) to account for future expansion.  This expansion is not quanitfiable now, but is assured.  How do account for this in the proposed model since the baseline will only size the fans for current model inputs.  I am using Trace 700 with the autosize PRM selected.

Any help is greatly appreciated.

 

Thanks,
