Dear eQUEST experts,

This is a LEED v4 C&S project modeled with eQUEST 3.65 build 7175 DOE 2.3.

System Type for the Baseline Case is System 5 ? Packaged VAV with HW boiler
and for the Proposed Model is Gas fired RTUs with Digital Series Fan
Powered Terminal (DTQS).

Comparing the annual energy costs of the two models, when I change terminal
type of the propose design system to Series PIU the energy costs of the
model increases by 12%, which indicates the baseline system is more
efficient the design system. Is this correct or there is something wrong
with the terminal type selection? INP and PD2 files of the model are
attached.

Thank you for your help.
