CONSTRUCTION DOCUMENTS

VAV TERMINAL UNITS (TYPICAL)

GENERAL:

EACH TERMINAL UNIT SHALL BE PROVIDED WITH APPLICATION SPECIFIC CONTROL MODULE (ASC). UNIT AIRFLOW SHALL BE

MONITORED BY AN INTEGRAL, MULTI-POINT, AVERAGING FLOW SENSING DEVICE AND TRANSDUCER TO MAINTAIN AIRFLOW

WITHIN 5% OF THE RATED CFM DOWN TO A MINIMUM CFM AS SCHEDULED, INDEPENDENT OF CHANGES IN SYSTEM STATIC

PRESSURE.

OCCUPIED COOLING CYCLE:

UPON A RISE IN SPACE TEMPERATURE ABOVE COOLING SETPOINT, THE TERMINAL UNIT SHALL MODULATE THE PRIMARY AIR

VALVE BETWEEN THE MINIMUM AND MAXIMUM AIR FLOW RATES SCHEDULED TO MAINTAIN SPACE TEMPERATURE SETPOINT.

OCCUPIED HEATING CYCLE:

IF THE TERMINAL UNITS AIR DAMPER IS IN THE MINIMUM POSITION AND THE SPACE TEMEPERATURE CONTINUES TO FALL BELOW

THE SPACE TEMPERATURE SET POINT, THEN THE TERMINAL UNIT HEATING WATER CONTROL VALVE SHALL MODULATE OPEN TO

MAINTAIN SPACE TEMPERATURE SETPOINT. WHEN IN HEATING MODE THE AIR TERMINAL UNIT SHALL REMAIN AT MINIMUM AIR

FLOW RATE (CFM) AS SCHEDULED.

UNOCCUPIED CYCLE:

IN ORDER TO MAINTAIN BUILDING PRESSURIZATION, THE AHU'S AND VAV AIR TERMINAL UNITS WILL OPERATE IN A SIMILAR

MANNER AS THE OCCUPIED MODE. HOWEVER, DURING THE UNOCCUPIED MODE SETBACK SPACE TEMPERATURE SETPOINTS WILL

BE USED.

VAV AIR HANDING UNIT WITH STATIC PRESSURE OPTIMIZATION (AHU-1):

OCCUPIED MODE:

COOLING:

WHEN THE AHU IS IN THE OCCUPIED COOLING MODE, THE SUPPLY FAN WILL OPERATE CONTINUOUSLY, THE VFD WILL MODULATE

TO MAINTAIN THE DUCT STATIC PRESSURE SETPOINT (AS DETERMINED BY TAB), AND THE COOLING VALVE WILL MODULATE IN

SEQUENCE TO MAINTAIN A CONSTANT DISCHARGE AIR TEMPERATURE OF 55 F (ADJ).

HEATING:

WHEN THE AHU IS IN THE OCCUPIED HEATING MODE, THE SUPPLY FAN WILL OPERATE CONTINUOUSLY, THE VFD WILL MODULATE

TO MAINTAIN THE DUCT STATIC PRESSURE SETPOINT (AS DETERMINED BY TAB), AND THE PRE-HEAT VALVE WILL MODULATE IN

SEQUENCE TO MAINTAIN A CONSTANT DISCHARGE AIR TEMPERATURE 52 F (ADJ). THE OA DAMPER SHALL BE SET TO THE

MINIMUM POSITION REQUIRED FOR SPACE VENTILATION. THE AIR SIDE ECOMONIZER MODE SHALL BE LOCKED OUT ANYTIME THE

UNIT IS IN HEATING MODE.

UNOCCUPIED MODE:

IN ORDER TO MAINTAIN BUILDING PRESSURIZATION, THE AHU'S AND VAV AIR TERMINAL UNITS WILL OPERATE IN A SIMILAR

MANNER AS THE OCCUPIED MODE. HOWEVER, DURING THE UNOCCUPIED MODE SETBACK SPACE TEMPERATURE SETPOINTS WILL

BE USED.

WARM UP AND COOL DOWN MODE:

THE DDC SYSTEM SHALL HAVE AN ALGORITHM TO ADJUST MORNING WARM-UP/COOL-DOWN SCHEDULE TO ENSURE THE SPACE

TEMPERATURE SETPOINTS ARE ACHIEVED PRIOR TO THE BUILDINGS OCCUPANCY SCHEDULE. MORNING WARM-UP/COOL-DOWN

SHALL BE SCHEDULED NO LESS THAN 1 HOUR (ADJ.) PRIOR TO OCCUPANCY. THE THE DDC SHALL ENERGIZE THE WATER LOOP

SYSTEMS TO MAINTAIN THE SPACE TEMPERATURE SET-POINTS .

SUPPLY FAN CONTROL:

THE SUPPLY FAN WILL OPERATE CONTINUOUSLY DURING OCCUPIED AND UNOCCUPIED MODES UNLESS THE STOP/AUTO

INTERLOCK IS OPEN, SMOKE DETECTION, THE MIXED AIR LOW LIMIT TRIPPED, OR THE SUPPLY FAN STATUS INDICATES A FAILURE

(AFTER A TWO MINUTE DELAY). THE LOW LIMIT, SMOKE DETECTION AND THE FAN FAILURE REQUIRE A MANUAL RESET.

VFD CONTROL:

WHEN THE SUPPLY FAN IS ON, THE VFD WILL SLOWLY RAMP (ADJUSTABLE) UP TO SETPOINT AND MODULATE TO MAINTAIN THE

PROPER DUCT STATIC PRESSURE SET POINT AS MEASURED BY A STATIC PRESSURE SENSORS LOCATED AT THE MID-POINTS OF

THE MEDIUM PRESSURE DUCT LOOP. THE FAN SPEED SHALL BE SET WITH WITH A HIGH STATIC LIMIT (3.75" IN W.C) AND IF THE

FAN EXCEEDS THE HIGH STATIC LIMIT AN ALARM SHALL BE SENT TO THE DDC. IF THE STATIC PRESSURE ACROSS THE FAN

EXCEEDS THE HIGH STATIC SHUTDOWN LIMIT (4 IN W.C.) THEN THE FAN SHALL BE DE-ENERGIZED AND ALARM SENT TO THE DDC.

THE VFD (VARIABLE FREQUENCY DRIVE) WILL BE OFF IF THE SUPPLY FAN IS OFF OR THE DUCT STATIC PRESSURE SENSOR

FAILS.

DUCT STATIC PRESSURE OPTIMIZATION:

THE DUCT STATIC PRESSURE SETPOINT SHALL BE RESET USING TRIM & RESPOND LOGIC WITHIN THE RANGE 0.15 IN. W.G. TO 1.3

IN. W.G. (35 PA TO 325 PA). WHEN THE FAN IS OFF, THE SETPOINT SHALL BE 0.5 IN. W.G. (125 PA). WHILE THE FAN IS PROVEN ON, EVERY TWO MINUTES, TRIM THE SETPOINT BY 0.04 IN. W.G. (10 PA) IF THERE ARE TWO OR FEWER ZONE PRESSURE REQUESTS. IF

THERE ARE MORE THAN TWO ZONE PRESSURE REQUESTS, RESPOND BY INCREASING THE SETPOINT BY 0.06 IN. W.G. (15 PA). A

ZONE PRESSURE REQUEST IS GENERATED WHEN THE VAV DAMPER IS GREATER THAN 95% OPEN UNTIL IT DROPS TO 80% OPEN.

COOLING VALVE CONTROL:

THE COOLING VALVE WILL MODULATE TO MAINTAIN THE SUPPLY AIR TEMPERATURE AT THE DISCHARGE COOLING SETPOINT OF

55°F (ADJUSTABLE). THE COOLING VALVE WILL BE CLOSED IF THE THE SUPPLY FAN IS OFF,OR THE DISCHARGE AIR SENSOR

HAS FAILED.

SMOKE DETECTION MODE:

WHEN SMOKE IS DETECTED AND FIRE ALARM SYSTEM ACTIVATED, THE BUILDING DDC SHALL INSTRUCT THE AHU TO STOP THE

FAN, CLOSE THE CHW & HW CONTROL VALVES, AND CLOSE THE OA & RA DAMPERS.

COOLING COIL FREEZE PROTECTION:

THE DDC SYSTEM SHALL CLOSE THE OA DAMPER ANYTIME THE COOLING COIL ENTERING AIR TEMPERAURE FALLS BELOW 40 F

FOR LONGER THAN 5 MINUTES. THE LOW LIMIT FREEZE STAT SHALL STOP THE AHU FAN ANYTIME THE COOLING COIL ENTERING

AIR TEMPERATURE FALLS BELOW 35 F. DURING LOW LIMIT FREEZE STAT CONDITION THE CHILLED WATER AND HOT WATER

CONTROL VALVES SHALL BE OPENED TO ALLOW CIRCULATION OF WATER TO PREVENT COIL FREEZE.

OUTSIDE AIR CONTROL:

THE DDC SYSTEM, WITH DUCT MOUNTED AIR FLOW MEASURING STATIONS (AFMS), SHALL MODULATE THE RA AND OA DAMPERS

AS REQUIRED TO MAINTAIN THE OA FLOW RATE CFM SCHEDULED. READOUT OF THE OA AIRFLOW RATE SHALL BE IN CFM. UPON

FAILURE THE OA DAMPER SHALL BE NORMALLY CLOSED.

AIR SIDE ECONOMIZER:

THE OA DAMPER SHALL MODULATE BETWEEN THE MINIMUM POSITION REQUIRED FOR SPACE VENTILATION TO FULLY OPEN

PROVIDING 100% OA IN ORDER TO MAINTAIN THE AHU SUPPLY AIR TEMPERATURE SETPOINT. THE AIR SIDE ECONOMIZER SHALL

BE ENABLED ANYTIME THE AMBIENT DRY BULB AIR TEMPERATURE IS BELOW 55 F AND THE AHU IS CALLING FOR COOLING. THE

AHU RA DAMPER SHALL BE LINKED WITH THE OA DAMPER OPERATION. THE OA DAMPER SHALL MODULATE TO PROVIDE ALL OR

SOME PORTION OF THE COOLING CAPACITY REQUIRED BY THE AIR HANDLING UNIT DURING COOLING MODE.

GENERAL EXHAUST SYSTEMS

EXHAUST FANS (EF-1, -2, -3, -4, -5):

A. EXHAUST FAN SHALL OPERATE CONTINUOUSLY 24 HR/7 DAY/WEEK.

ISOLATION ROOM SYSTEM

THE HVAC SYSTEMS SERVING THE ISOLATION ROOM SHALL OPERATE CONTINUOUSLY 24 HR/7 DAY/WEEK.

A SPACE PRESSURIZATION MONITOR PANEL (SPM) WILL MONITOR AND CONTROL THE SPACE PRESSURIZATION LEVEL AS

COMPARED WITH THE DIALYSIS STATION OPEN BAY AREA. THE SPM SHALL HAVE A 2-POSITION KEY SWITCH THAT

ALLOWS LOCAL CONTROL FOR SETTING THE ISOLATION ROOM TO BE MAINTAINED AT EITHER NEGATIVE OR NEUTRAL

PRESSURE. THE SPM SHALL MODULATE THE CONSTANT VOLUME SUPPLY AIR TERMINAL BOX AND THE PATIENT ROOM

EXHAUST AIR DAMPER TO MAINTAIN AIRFLOW DIFFERENTIAL BASED ON THE MODE OF OPERATION (NEGATIVE OR

NUETRAL). THE SPM SHALL REPORT SPACE PRESSURE DIFFERENATIAL READINGS AND SETPOINT VALUES TO THE DDC

SYSTEM AND A REMOTE PANEL MONITOR (RPM) LOCATED AT THE NURSE STATION. WHEN THE SPACE PRESURIZATION IS

OUT OF RANGE A LOCAL AUDIBLE AND VISUAL ALARM WILL BE INITIATED AT THE SPM, THE RPM AND A ALARM SIGNAL

WILL BE SENT TO THE DDC SYSTEM.

THE SUPPLY AIR TERMINAL UNIT REHEAT WILL MODULATE TO MAINTAIN ROOM TEMPERATURE SETPOINT.

CHILLED WATER SYSTEM (CHWP-1 & CHWP-2)

GENERAL:

THE CHILLED WATER LOOP SYSTEM IS A VARIABLE FLOW, BUILDING TERTIARY LOOP TYPE. THE CHILLED WATER IS

SUPPLED FROM A CAMPUS CHILLED WATER LOOP PROVIDED FROM OFFSITE CENTRAL ENERGY PLANT. THE CHILLED WATER

LOOP SYSTEM CONSISTS OF (2) CHILLED WATER PUMPS, (2) PUMP MOTOR VFD'S, ASSOCIATED CONTROLS AND VALVES.

EACH CHILLED WATER PUMP IS SIZED TO PROVIDE 100% OF THE REQUIRED CHILLED WATER WATER FLOW RATE INCLUDING

ADDITIONAL FLOORS (2-4) PLANNED FOR CONSTRUCTION IN THE FUTURE.

CHILLED WATER (CHWP-1 & CHWP-2):

STARTING AND STOPPING OF THE CHILLED WATER PUMP SHALL BE ACCOMPLISHED WITH A VFD. PROVIDE CHILLED WATER

PUMP WITH A HAND-OFF-AUTO SWITCH. IN THE "HAND" POSITION, THE PUMP SHALL BE CONTROLLED MANUALLY. IN THE

"AUTO" POSITION THE PUMP SHALL BE CONTROLLED BY THE DDC SYSTEM. THE DDC SYSTEM SHALL START THE MAIN

CHILLED WATER PUMP ANY TIME THE AHU OR FAN COIL UNIT IS CALLING FOR COOLING. UPON CALL FOR COOLING THE

DECOUPLER VALVE (NORMALLY CLOSED) SHALL MODULATE OPEN TO MAINTAIN THE PRIMARY CHWS LOOP TEMPERATURE

OF 42 F (ADJ).

THE CHILLED WATER PUMPS SHALL BE OPERATE IN A MAIN / STAND-BY CONFIGURATION TO ENSURE EQUAL PUMP RUN TIME.

THE ALTERNATION FUNCTION REVERSES THE OPERATION OF THE PUMPS. UPON ALTERNATION THE MAIN PUMP SHALL

ROTATE TO STAND-BY AND THE STAND-BY PUMP SHALL ROTAE TO THE MAIN POSITION. THE ALTERNATION FUNCTION

SHALL BE PROGRAMMED TO OCCUR ANYTIME THE ACTIVE MAIN PUMP COMES TO REST.

DIFFERENTIAL PRESSURE CONTROL:

THE OBJECTIVE FOR THE CHILLED WATER PUMP OPERATIONS IS TO ALWAYS HAVE THE PUMP OPERATE AT THE LOWEST

SPEED AND PRESSURE POSSIBLE TO SATISFY THE BUILDING LOAD. THE LOOP DIFFERENTIAL SETPOINT WILL BE MAINTAINED

AT THE PRESSURE SETPOINT REQUIRED TO PROVIDE FULL FLOW TO ALL CONTROL VALVES SIMULTANEOUSLY (PER TAB

REPORT).

HOWEVER, IF THE PUMP VFD HAS BEEN RESET TO THE MINIMUM SPEED ALLOWABLE (TAB VERIFY) AND THE LOOP

DIFFERENTIAL PRESSURE CONTINUES TO RISE ABOVE THE MAXIMUM PRESSURE SETPOINT. THEN THE LOOP BYPASS VALVE

SHALL OPEN TO MAINTAIN THE DIFFERENTIAL SETPOINT AND THE MINIMUM PUMP SPEED (15Hz).

HOT WATER LOOP SYSTEM (HX-1, HX-2, HWP-1 & HWP-2):

GENERAL:

THE HOT WATER LOOP SYSTEM IS A PRIMARY LOOP SERVING THE AHU AND AIR TERMINAL UNIT REHEAT COILS. THE HOT
