Hi,

One of my LEED project received a standard comment as:

*Energy recovery is modeled for credit in the Proposed Case. Provide
further information regarding the energy recovery efficiency, verify that
outside air is modeled with zero flow in both the Baseline and Proposed
Case during unoccupied periods when fans are cycled on to meet unoccupied
setback temperatures unless health or safety regulations mandate an
alternate minimum flow during unoccupied periods (in which case, the
unoccupied outside air rates should be modeled identically in the Baseline
and Proposed Case), and indicate the bypass mechanism used to bypass the
energy recovery during mild conditions.*
I need to know,what exactly i need to do in E-quest model.as per my
understanding,i need to Keep Fan operation on by putting the fixed set
point temp. control with bypass mechanism.
But how exactly it will consider schedule for unoccupied hours.And how
bypass mechanism will serve the purpose during mild condition?
Please guide to resolve this query.
