Dear All,

We have received the following from GBCI regarding the energy modelling
review:

"Table1.4.2 indicates that exhaust fan systems are reflected in the
Proposed model; however, the equipment capacities are inconsistent with the
exhaust fan systems (EF-1 through EF-9) as indicated in the mechanical
schedules provided for PI Form 4: Schedule and Overview Documents. In
addition, the independent fan systems of the HVAC systems in the actual
design must be modeled identically between the Proposed and Baseline
models at actual equipment capacities (fan volume and fan power) as
required by Table G3.1.10 in the Proposed building column, since the fan
design
air flow rates and fan power per Sections G3.1.2.8 and G3.1.2.9,
respectively, only applies to system types 1 through 8 in Table G3.1.1A.
Revise the
Proposed and Baseline models so all independentfan systems of the HVAC
systems are modeled identically between the Proposed and Baseline
models. In addition, separate the energy consumption and peak demand
energy for independent#fans in Table EAp2-4 and Table EAp2-5 of the
prerequisite form. Further,provide revised SV-A reports reflecting the
changes"

Our proposed model has supply and exhaust fans (Supply: AHU, FCU -
Exhaust: AHU, independant exhaust fans). Our baseline model has supply
and relief fans (VAV System).

Please look at Section 6 of the attached Table 1.4.2. Are we expected to
additionally model exhaust fans in the baseline case? Do they mean
exhaust fans when they say "independent fan systems of the HVAC systems?".

Thanks for all replies,

Omer Moltay, LEED AP BD+C
