The current mechanical system consists of air handling units (AHU), condensing units, perimeter

radiation,reheatcoils,gasfiredboilers,hotwatercirculatingpumps,andamixtureofpneumaticand

Direct Digital Controls (DDC) controls. With the exception of the DDC controls and a booster fan

between thebuilding addition and theexisting library is alsoproblematic. Theexteriorwallsof the

Energyrecoveryventilatorswouldtransferbothheatandhumidityfromthebuildingsexhaustairto

could be utilized to provide perimeter infloor heat, contributing to the thermal comfort of the

building.

VAVwithHydronicHeatingandCooling

This system would consist of air handling units, VAV boxes with reheat coils, high efficiency air

cooled chillers andboilers. The airhandlingunitswouldbe equippedwith the followingenergy

efficient features: economizer cooling, variable frequency fan drives, and energy recovery. The

hydronicheatingand cooling systemswould incorporate twoway controlvalvesandpumpswith

variable frequencydrives. Perimeterheating canbeprovidedbywayof infloorheator fin tube

radiation.

Regardless of the mechanical system, Direct Digital Control (DDC), Demand Control Ventilation

(DCV),andbuildingcommissioningshouldbeutilizedinthedesign.

DDC is anecessity for an energy efficientmechanical system. DDC uses inputs from sensors to

controlequipmentsuchasvalves,dampers,andfans. Thesecontrolsareusedinconjunctionwitha

software package or Building Automation System (BAS), which graphically displays equipment

operation, building temperatures, trending, and alarms. The BAS also allows maintenance

personneltomonitorandcontrolthebuildingsmechanicalsystemsremotelyviatheinternet.

determine theoccupancy levelofthe libraryandmodulate theamountofoutsideair tomaintain

acceptablelevelsofCO2. Amodulatingfanwouldadjusttheamountofexhaustairtoensureproper

buildingpressurization.

Buildingcommissioningensures thatbuildingsystemsare installedandoperatingper theowners
