NOTES: 2011 - 2013 billing data exemplifies increasing usage profile in parallel to owner population of process operating equipment (pre-final day). Proposed building data reflects a "final day" energy
usage projection. The non-HVAC energy use electrical equipment projections reflect the plant process load associated with machining, fabrication, assembly, and transport of product.

IAQ and Thermal Comfort
Facility system design incorporates significant indoor
environmental quality measures.
All HVAC systems that incorporate an outside air component incorporate ³30% increased outdoor airflow per
Table 6-1 (ASHRAE Standard 62.1-2007), dynamic outdoor air path flow measurement, and MERV-7/14 or 8/13
(two-stage) filtration.
The main office and employee services areas use
DOAS units to provide dry, constant volume ventilation air directly to each occupied space. Ventilation
load is decoupled from building load so that dehumidification and sensible cooling can be addressed
independently. Constant ventilation airflow is

maintained via measurement of airflow and modulation of fan speed as MERV-8/13 filter loading
increases. Additionally, the DOAS units provide space
dew-point control. All in-plant offices are served
with 100% outdoor air to provide positive pressure
relationship to plant conditions. In-plant office pressurization air is subsequently used as transfer air for
select plant exhaust systems.
Plant production zones use 100% outdoor air systems with energy recovery wheels to provide ventilation, zoned pressurization, and process exhaust
makeup air. Plant zones incorporate dynamic, cascading pressure relationship measurement to maintain
air quality and cleanliness needs across plant zones.
