Convert “Constant Air Volume” to “Variable Air Volume

Individual zone controlOccupant perception of local controlFlexibility to adapt to changeReduced ductwork and AHU sizeMonitor and record space temperaturesAllows for efficient use of static pressure reset

Convert “Pneumatic” to “Direct Digital Controls”

Precise positioning of dampers and valvesIdentifying trends Eliminate the need to change time clocks for holidays and schedule changes.Does not drift out of calibration and suffer from "offset"Provides energy savings by removing compressed air losses

Add AirCuity® Centralized Demand Control Ventilation

Monitors air quality and increases air change rate as neededAllows unoccupied spaces to be set to 2 air changes and occupied spaces to be set to 4 air changes in typical building uses.Emergency override “red” button allow for occupant override of air change rate

“Exhaust Stack Ventilation Discharge Reduction”

Wind tunnel and field dispersion studies based on post build out and chemical loads of the lab building are used to determine safe stack velocities for plume dispersionIncreased stack height may allow for significant velocity reductionCombining manifolds of exhaust fans to reduce maintenance cost and increase efficiencyEliminates or reduce need for wasteful bypass air.

Add Low Pressure Drop FiltersReduce required fan energy to meet static pressure requirements

Convert to Variable-Frequency Drives

Allow for maximum air handler fan control, saving energy by modulation the fan to match building demandAllows for maximum chilled water and high temp hot water control saving energy by modulation pump motors to meet demand

Premium Efficiency MotorsMotor upgrade may be required when adding a VFDDirect drive motors will also provide efficiency gainsMotors should be examined for proper sizing at the time of retrofit.

Static Pressure ResetAdded after conversion to VFD and VAV systemAHU fan speed, chilled and hot water usage can be reduced by supplying only the energy required to maintain duct pressure which will modulate based on downstream VAV box damper position

Add Day-lighting ControlsLower blinds to allow day-lightingDaylight sensors step dim lights as they get closer to the window

Add Occupancy ControlsAuto on to 50%Manual on to 100%Auto off

Reduce Operation Hours with OverrideFully utilize building EMS for office and common areasInstall time-clocks on lighting not utilizing occupancy controlsReduce scheduled hours for HVAC and add 2 hour pushbuttons in each zone to over-ride.

Install Solar Window FilmRejects up to 79% of solar heat gainMakes occupants more likely to take advantage of day-lighting.
