1.2 DEFINITIONS 1.2.1 ANSI/ASHRAE Standard 135 ANSI/ASHRAE Standard 135: BACnet - A Data Communication Protocol for Building Automation and Control Networks, referred to as "BACnet". ASHRAE developed BACnet to provide a method for diverse building automation devices to communicate and share data over a network.

1.2.2 BACnet


Section 23 09 23.13 22 Page 3

Building Automation and Control Network; the common name for the communication standard ASHRAE 135. The standard defines methods and protocol for cooperating building automation devices to communicate over a variety of LAN technologies.

1.2.3 BACnet/IP An extension of BACnet, Annex J, defines this mechanism using a reserved UDP socket to transmit BACnet messages over IP networks. A BACnet/IP network is a collection of one or more IP subnetworks that share the same BACnet network number. See also "BACnet Broadcast Management Device".

1.2.4 BACnet Internetwork Two or more BACnet networks, possibly using different LAN technologies, connected with routers. In a BACnet internetwork, there exists only one message path between devices.

1.2.5 BACnet Network One or more BACnet segments that have the same network address and are interconnected by bridges at the physical and data link layers.

1.2.6 BACnet Segment One or more physical segments of BACnet devices on a BACnet network, connected at the physical layer by repeaters.

1.2.7 BBMD BACnet Broadcast Management Device (BBMD). A communications device, typically combined with a BACnet router. A BBMD forwards BACnet broadcast messages to BACnet/IP devices and other BBMDs connected to the same BACnet/IP network. Every IP subnetwork that is part of a BACnet/IP network must have only one BBMD. See also "BACnet/IP".

1.2.8 BAS Building Automation Systems, including DDC (Direct Digital Controls) used for facility automation and energy management.

1.2.9 BIBBs BACnet Interoperability Building Blocks. A collection of BACnet services used to describe supported tasks. BIBBs are often described in terms of "A" (client) and "B" (server) devices. The “A” device uses data provided by the "B" device, or requests an action from the “B” device.

1.2.10 BI BACnet International, formerly two organizations: the BACnet Manufacturers Association (BMA) and the BACnet Interest Group - North America (BIG-NA).

1.2.11 BI/BTL

1.2.18 Digital Controller An electronic controller, usually with internal programming logic and digital and analog input/output capability, which performs control functions. In most cases, synonymous with a BACnet device described in this specification. See also "Device". There are different levels of controllers, with varying levels or complexity and flexibility.

1.2.18.1 Terminal Device Controllers Terminal device controllers typically are controllers with less control features, may have integrated actuators, and may be mounted directly on equipment (with enclosures).


Section 23 09 23.13 22 Page 5

1.2.18.2 Field Controllers Field controllers typically have a greater capability for input/output and customization, do not have integral actuators, are mounted in an enclosure not on the equipment and are used for equipment such as VAV air handlers.

1.2.18.3 Plant Controllers Plant Controllers are typically used to control various equipment in mechanical rooms such as pumps, heat exchangers, and chillers.

1.2.18.4 Supervisory Controllers Supervisory Controller is used to coordinate all equipment in a building, input scheduling, and is often used as a connection point for transferring configuration files to the other controllers.

1.2.18.5 Supervisory Building Controller (SBC) Supervisory Building Controller (SBC) is used to connect the building's DDC system (MS/TP) to Camp Lejeune's EMCS (TC/IP). Depending on approvals and capabilities, the SBC and supervisory controller may be combined into the same piece of hardware.

1.2.19 Direct Digital Control (DDC) Digital controllers performing control logic. Usually the controller directly senses physical values, makes control decisions with internal programs, and outputs control signals to directly operate switches, valves, dampers, and motor controllers.

1.2.20 DDC System A distribution network of digital controllers, communication architecture, and user interfaces. A DDC system may include programming, sensors, actuators, switches, relays, factory controls, operator workstations, and various other devices, components, and attributes.

HVAC Systems HVAC System Description The HVAC system uses terminal dual-temperature water (DTW) fan coil units (FCUs) to condition the building rooms and heating hot water (HHW) radiator heaters to heat the restroom areas of the building. The DTW coils within the FCUs use chilled water (CHW) or HHW, depending on the season, and share a common constant volume pump. The CHW is supplied by a 60-ton air-cooled chiller. The HHW system includes a steam-to-HHW heat exchanger (HX). The HHW radiators are supplied HHW with a separate pumping loop. The fitness area of the building uses a mini-split air conditioner. Exhaust fans (EFs) provide general building exhaust air relief. The chiller, HHW HX, and associated distribution systems are controlled by an electronic control system. The FCUs, radiator heaters, and EFs are locally controlled by manual thermostats or switches.

HVAC Systems HVAC System Description The HVAC consist of four central variable air volume (VAV) air-handling units (AHUs) that utilize chilled (CHW) coils and heating hot water (HHW) coil to condition the building. In addition, dual-temperature terminal fan coil units provide cooling and heating in common areas. The AHUs supply air to the terminal VAV boxes with HHW reheat coils. The AHU supply and return fan motor nameplates were inaccessible at the time of the audit. The chilled water is provided by a 52-ton packaged air-cooled chiller and constant-volume CHW pump. The HHW system includes a steam-to-HHW heat exchanger (HX) and constant-volume HHW pump. Exhaust fans provide restrooms with exhaust air relief. The AHUs are controlled by a direct digital control (DDC) system and the VAV boxes with reheat coils are controlled by pneumatic thermostats.

HVAC Systems The heating, ventilation, and air conditioning (HVAC) system consists of five multi‐zone air‐handling units (AHUs)

that condition a majority of the building. The AHUs have dual‐temperature coils that cool or heat the air

depending on the season. An air‐cooled chiller provides chilled water (CHW) to the AHUs and a steam‐to‐hot

water heat exchanger provides heating hot water (HHW). A single base‐mounted end suction pump distributes

the CHW or HHW from the primary system loop to the AHUs. Multiple ductless split‐system (DSS) and split

system (SS) units condition the basement offices and other various spaces. The HVAC system is controlled

pneumatically. Exhaust fans (EFs) provide restroom and general building exhaust.

HVAC Systems HVAC System Description The HVAC system consists of three split system direct expansion (DX) heat pumps with supplemental heat and multiple two‐pipe fan coil units (FCUs). The FCUs are served by a dual temperature system. An air‐cooled chiller provides chilled water (CHW) and a steam to hot water heat exchanger (HX) provides the heating hot water (HHW) for the dual temperature loop. Two inline pumps controlled in a lead/standby configuration distribute the CHW and HHW throughout the building. The pumps are located within a confined space and were not accessible. Hot water unit heaters provide heating to the vehicle bay areas and a few additional spaces. Two packaged terminal air conditioner (PTAC) units condition the weight room space. Two additional PTACs condition a few spaces located in the new expansion. General exhaust for the building is via roof and ceiling mounted fans controlled by wall switches. The two vehicle bay areas each contain a vehicle exhaust system.

HVAC Systems HVAC System Description The heating, ventilation, and air conditioning (HVAC) system consists of seven variable air volume (VAV) air‐handling units (AHUs) with associated terminal VAV boxes to condition the majority of the building. The AHUs have inlet vanes to control air volume. Some smaller split direct expansion (DX) systems are used to condition critical areas with high cooling loads.

The HVAC system is served by a dual‐temperature water (DTW) system (two‐pipe system) for heating hot water (HHW) or chilled water (CHW), depending on the season. CHW is provided by an air‐cooled chiller and HHW is produced by a steam to hot water heat exchanger (HX). Both the CHW and HHW loop have constant‐volume pumping. The HVAC system is controlled by pneumatic controls.

HVAC Systems HVAC System Description The heating, ventilation, and air conditioning (HVAC) system consists of four variable air volume (VAV) air‐handling units (AHUs) with associated VAV boxes to condition the majority of the building. The AHUs use a dual‐temperature water (DTW) coil for cooling and heating. A fifth VAV AHU with associated VAV boxes serves a portion of the first floor. This unit has a direct expansion (DX) coil for cooling and a dual‐temperature coil for heating. The chilled water (CHW) is produced by an air‐cooled chiller, and heating hot water (HHW) is produced by a steam‐to‐hot water heat exchanger. Both the CHW and HHW systems have primary inline pumps. A secondary DTW pump distributes DTW to the coils throughout the building. Two split‐system air conditioning (AC) units serve the chapel area. Two ductless split systems provide cooling to spaces with high heat gain. The HVAC systems are controlled by pneumatic controls. General exhaust for the building is by ceiling‐mounted fans controlled by wall switches.

HVAC Systems HVAC System Description The heating, ventilation, and air conditioning (HVAC) system consists of six variable air volume (VAV) air‐handling units (AHUs) with associated terminal VAV units to condition the majority of the building. Fan coil units (FCUs) are used to condition some of the core spaces. Most of the HVAC equipment appears to be in fair operating condition.

The HVAC system is served by a dual‐temperature water (DTW) system (two‐pipe system) for heating hot water (HHW) or chilled water (CHW) depending on the season. The DTW loop is supplied through Building HP56. The DTW system serves the AHUs, FCUs, and unit heaters.

Chilled Water System CHW is produced at a central chiller plant located in Building HP52. The chilled water serves each AHU through the DTW system.

Heating Hot Water System HHW is provided by a steam to hot water heat exchanger located in Building HP52. The HHW serves each AHU through the DTW system.

Air-Handling System One VAV AHU is located within each of the six mechanical rooms (two per floor). Each AHU serves VAV terminal boxes located in individual rooms. The AHUs provide heating and cooling through a DTW coil. The DTW coils use three‐way control valves. A variable frequency drive (VFD) controls the speed of each AHU supply fan. Most VFD controllers were found to be operating at 100 percent at the time of the site visit.

Outside air is brought into the building through outside air dampers on each AHU. The dampers are automatically controlled to determine a percentage of outside air. The dampers were found to be 100 percent open at the time of the site visit.

HVAC Systems HVAC System Description The heating, ventilation, and air conditioning (HVAC) system consists of two direct exchange (DX) air conditioning systems, general exhaust fans, heating hot water (HHW) fan coil units (FCUs), and HW unit heaters (UHs).

Heating Hot Water or Steam System Steam is used to produce HHW in the mechanical room; the HHW, which is used throughout the building, provides motive energy for the condensate receiver pump.

The HHW for the building is produced using a steam‐to‐HHW shell‐and‐tube heat exchanger (HX). Steam to the HX is controlled using a two‐way modulating control valve based on the HHW supply and return temperatures. The HHW is circulated through the system using a constant‐volume HHW pump. The pump nameplate data was illegible. The HHW is used in all the HVAC equipment coils as well as for the domestic hot water (DHW) tank, which is an immersion‐style HX for producing DHW. The HHW system is controlled by a direct digital control (DDC) system.

Air-Handling System There are two 7.5‐ton DX air‐handling units (AHUs) located in the second floor mechanical room that serve the office areas of the building. The AHUs provide heating and cooling through separate HHW and refrigerant coils. The associated air‐cooled condensing units are located outside the first floor mechanical room. Outside air is brought into each unit through control dampers located in the mechanical room.

HVAC Systems HVAC System Description The HVAC system consists of one central split system air-handling unit (AHU) utilizing direct exchange (DX) coils and a condensing unit for air conditioning and heating hot water (HHW) coils for heat to condition administrative rooms of the building. The building also utilizes five AHUs utilizing HHW coils to heat the air supplied to the maintenance bays with additional HHW reheat for specific spaces, six HHW unit heaters (UHs) and three HHW fan coil units (FCUs) units provide heat in other spaces. The AHUs supply and return fan data indicates installation in 1988, but no other data was accessible. The HHW is produced in the mechanical room using a steam to HHW heat exchanger (HX) and circulated through the building with a constant volume HHW pump. Exhaust fans (EFs) provide restroom and general building exhaust air relief. Additional EFs are used in the maintenance bay areas for vehicle exhaust. The HVAC systems use pneumatic controls. The other systems are controlled by local thermostats in the areas served by the system.

Heating Hot Water or Steam System (Including Pumping) The HHW is produced by a steam to hot water heat exchanger.

HVAC Systems HVAC System Description The heating, ventilation, and air conditioning (HVAC) system consists of six variable air volume (VAV) air‐handling units (AHUs) with associated terminal VAV units and two ERVs to condition the majority of the building. Fan coil units (FCUs) are used to condition some of the core spaces. Most of the HVAC equipment appears to be in good operating condition.

The HVAC system is served by a dual‐temperature water (DTW) system (two‐pipe system) for heating hot water (HHW) or chilled water (CHW) depending on the season. The DTW loop is supplied through Building HP561. The DTW system serves the AHUs, ERVs, FCUs, and unit heaters.



Air-Handling System One VAV AHU is located within each of the six mechanical rooms (two per floor). Each AHU serves VAV terminal boxes located in individual rooms. The AHUs provide heating and cooling through a DTW coil. The DTW coils use three‐way control valves. A variable frequency drive (VFD) controls the speed of each AHU supply fan. Most VFD controllers were found to be operating at 75 percent at the time of the site visit.

Outside air is brought into the building through one of two ERVs located in the attic space. The outside air is then directly ducted to each AHU, each of which has its own actuated outside air damper for control of air to the unit. Each ERV serves three AHUs. Each ERV includes a heat wheel, a DTW coil, an exhaust fan, and a supply air fan. The ERVs also serve as general exhaust for the building.

Terminal Units VAV Boxes The series fan‐powered terminal VAV boxes are air valves only and do not have reheat capability. One VAV box is provided for each BEQ room. Each VAV box is controlled by a Johnson Controls temperature sensor thermostat.

FCUs The Duty Office uses a floor‐mounted DTW FCU to provide heating and cooling. The recreational/lounge rooms located on each floor use ceiling‐mounted DTW FCUs.

Unit Heaters Each laundry room, with the exception of the large one on the first floor, has a UH which is connected to the DTW loop. The UH valve is designed to be closed in the summer months.

Exhaust Fans The main building exhaust is through the two ERVs located in the attic. Each laundry room has a small wall‐mounted exhaust fan for heat relief. The laundry room EFs are controlled by wall‐mounted manual thermostats. The EFs appeared in fair condition.



Controls and Operational Characteristics The building systems are controlled with a direct digital control (DDC) system, but the DDC system is not currently connected to the basewide energy management and control system (EMCS). The DDC controls operate to control the VFD on each AHU, the automatic dampers on supply, mixed, and outside air to each AHU, the three‐way valve on the coil, and each the damper on each VAV box in the space. The two‐pipe system in the building requires manual changeover. The building does not currently use schedules of occupancy.

HVAC Systems HVAC System Description The HVAC system consists of three constant air volume (CAV) air-handling units (AHUs). The supply air is conditioned by dual temperature water (DTW) coils within the AHU that utilize chilled water (CHW) or heating hot water (HHW) depending on the season; the DTW coils share common constant volume distribution pumps. The CHW is supplied by an air-cooled split-system chiller. The HHW system includes a steam-to-HHW heat exchanger (HX). The building also utilizes DTW fan-coil units (FCUs), HHW unit heaters (UHs), and finned-coil heaters. Exhaust fans (EFs) provide restroom and general building exhaust air relief. Additional EFs are used in the maintenance bay areas for vehicle exhaust. The HVAC systems are controlled by direct digital control (DDC) and electronic control systems.

Domestic Hot Water System A new domestic hot water system was being installed at the time of the audit. The new system will consist of a steam‐to‐hot water heat exchanger.

HVAC Systems HVAC System Description The primary heating, ventilation, and air conditioning (HVAC) systems serving the office portions of this building were being completely replaced at the time of this observation, with the work being about 90 percent complete. The new systems will continue to utilize steam for building heating with new steam‐to‐hot water heat exchanger (HX) and pump being installed. A new air‐cooled chiller with pump was being installed for the cooling system. The system will consist of ceiling‐mounted heat pumps that will work in conjunction with a roof‐mounted energy recovery ventilator (ERV). New controls for these systems will be a programmable direct digital control (DDC) system. The heating and ventilation systems in the maintenance shop areas of the building are not a part of the remodel and consist of roof structure‐mounted forced air HHW unit heaters and HHW make‐up air units. Exhaust systems are switch‐operated and provide bay ventilation; separate fans provide vehicle exhaust removal.

HVAC Systems HVAC System Description The primary heating, ventilation, and air conditioning (HVAC) system consists of a built‐up air‐handling unit (AHU) with direct expansion (DX) split‐system cooling, heating hot water (HHW) coil, and modulating outside air (OA) ventilation. A separate built‐up make‐up air unit (MAU) also includes a HHW coil. HHW for the facility is produced by steam‐to‐hot water heat exchanger (HX) and circulation pump. The outdoor air‐cooled DX chiller is a recent replacement that operates on R‐22 refrigerant. Control is provided by a direct digital control (DDC) system with room sensors. There are three packaged terminal air conditioning (PTAC) units at perimeter office locations.

The main function of the building is a Mess Hall and most roof equipment was expressly provided for Type I and II hood operations. The controls found in the kitchen prep spaces indicate an On/Off function for each hood and its related fan(s). Liquefied petroleum gas (LPG) is available onsite, but at the time of the audit it appeared to be used for cooking equipment only.

HVAC Systems HVAC System Description The HVAC system consists of six central variable air volume (VAV) air-handling units (AHUs) that use variable frequency drives (VFDs) for fan motor control. The supply air is conditioned by dual-temperature water (DTW) coils within the AHUs, which use chilled water (CHW) or heating hot water (HHW) depending on the season. Each AHU uses a three-way control valve to control the DTW flow. The AHUs supply conditioned air to terminal fan-powered VAV boxes. The AHU supply and return fan motor data were inaccessible. The DTW is supplied from an adjacent utility building (FC361). The CHW and HHW motor and pump data was inaccessible. Outside air (OA) to the building and general exhaust from the building is through two energy-recovery ventilators (ERVs). The OA is preconditioned in the ERV with a DTW coil and by exchanging energy with the exhaust air and is supplied to each AHU through a VAV Box. The building utilizes HHW unit heaters (UHs) in the laundry rooms. Exhaust fans are used in the laundry rooms, AHU mechanical rooms, and in the common restrooms on each floor. The AHUs, ERVs, terminal VAVs, and DTW system are controlled by a direct digital control (DDC) system. The UHs and other EFs are locally controlled by manual thermostats or switches.
