Service Hot Water

Dear fellow LEEDusers. Our base building (C&S) has not included a service hot-water system (it will be installed by tenants later) and therefore we modelled the Proposed Building Performance and the Baseline Building Performance identically. However, we have received a design review comment saying: "Tables EAp2-4 and EAp2-5 indicate that service water heating energy has been modeled identically as a process load for both the Baseline and Proposed Case models, which is unexpected. Revise both models to ensure that the Baseline Case service water heating energy is modeled per ASHRAE 90.1-2007 Appendix G and the Proposed Case service water heating energy is modeled as designed. Revise Table 1.4 and the form as necessary." Do you any idea where is the mistake? Thank you in advance.
