1.04 QUALITY ASSURANCE A. Design system under direct supervision of a Professional Engineer experienced in design of

this Work and licensed at the State in which the Project is located. PART 2 PRODUCTS - NOT USED PART 3 EXECUTION

A. Review and when needed modify the Sequences for the following systems so the Sequences include the following.

3.01 AIR TERMINAL UNITS

Modify the Seqeunce of Operation listed on the Johnson Controls Clark County Community Health Center Control Drawings dated 11/15/2004 so the following is incorporated.

a) Implement zone level schedules (per schedule guidelines provided) for all TUs on AHU-001 and AHU-002. This represents total of (137) TUs.


b) Modify and document all relevant zone temperature parameters to achieve air flow and temperature setpoints described above, on all TUs. This represents a total of (116) standard VAV TUs and (60) series fan-powered TUs.

Detailed Scope Description - Scheduling:

1) Total number of boxes per AHU that is allowed to go to zero airflow will be determined during implementation so minimum fan speed and duct pressure will be within allowable limits.

2) Adjust AHU-001 system occupied/unoccupied period schedule to operate in occupied mode from 6 AM to 1 AM, on weekdays. Unoccupied mode will be scheduled for all other hours. This will control both supply fan and return fan operation, and will save fan energy, cooling energy, and heating energy.

3) Leave system level schedules unchanged for remainder of units. (No savings.) 4) Schedule all TUs on AHU-001 to have occupied-unoccupied periods corresponding to actual

zone-level occupancy. Zone schedules remain to be developed as part of technical support for re-commissioning.

5) Schedule all TUs on AHU-002 to have occupied-unoccupied periods corresponding to actual zone-level occupancy. Zone schedules remain to be developed as part of technical support for re-commissioning. It is assumed that most zones will be scheduled to be unoccupied at 5 pm.

Detailed Scope Description - Setpoints:

1) Confirm that the standard VAV TU controllers can be programmed in dual maximum air flow mode, i.e., there are four (4) air flow setpoints on each controller for occupied period and four (4) air flow setpoints on each controller for unoccupied period. Based on a review of Johnson Controls literature for the VMA1420 controller, it appears that the standard VAV TU applications can be configured with dual maximum air flow setpoints, and can have separate heating and cooling minimum setpoints for unoccupied periods.

2) Setpoints are proposed to be modified as follows for standard VAV boxes. Note that boxes on systems AHU-101, 102, 103, and 104 will not have any unoccupied periods.

a. Cooling Max Flow: Existing setpoints shall remain unchanged.

b. Occupied Clg Min: 20% of cooling maximum (unless ventilation requirements dictate otherwise).

c. Unoccupied Clg Min: 0 (full closed damper)

d. Heating Max Flow: 70% of cooling maximum

e. Occupied Htg Min: Equal to occupied clg min.

f. Unoccupied Htg Min: 0 (full closed damper)

3) Setpoints are proposed to be modified as follows for series fan-powered VAV boxes. Note that boxes on systems AHU-101, 102, 103, and 104 will not have any unoccupied periods. When unit is in occupied heating, primary air dampers will be in cooling minimum position (20%.) When unit is in unoccupied heating mode, primary air dampers will be closed and unit will operate in full re-circulation mode.

a. Cooling Max Flow: Existing setpoints shall remain unchanged.


b. Occupied Clg Min: 20% of cooling maximum (unless ventilation requirements dictate otherwise).

c. Unoccupied Clg Min: 0 (full closed damper)

4) Increase occupied period zone temperature setpoint deadband from 1 deg. F to 4 deg. F.

a. For occupied period, the following modifications will result in setpoints typical setpoints of 70 F (heating) / 74 F (cooling) when there is no remote adjustment enabled. Ensure that seasonal setpoint compensation parameters are such that the 4 deg. F deadband is maintained during both heating and cooling seasons.

I. Common setpoint: 72 F

II. Cooling bias: +2.0 F

III. Cooling setpoint: 0 F

IV. Heating bias: - 2.0 F

V. Heating setpoint: 0 F

b. For unoccupied period, the following modifications will result in setpoints typical setpoints of 60 F (heating) / 85 F (cooling) when there is no remote adjustment enabled.

I. Common setpoint: 72 F

II. Cooling bias: +13.0 F

III. Cooling setpoint: 0 F

IV. Heating bias: -12.0 F

V. Heating setpoint: 0 F

3.02 CHILLER (CH-1 through 5) CONTROL PROGRAMS A. Chiller Control Sequence shall follow the sequence listed on drawing CS-1-1 in the Johnson

Controls Clark County Community Health Center Control Drawings dated 11/15/2004 and include the following modifications.

Modification to the sequence shall include the following:

a) Chilled water reset temperature shall be based on polling chilled water valve positions for all the AHUs and adjusting in a linear fashion the chilled water supply temperature setpoint so at least one valve is between 90% to 95% open. Minimum and maximum setpoints shall be 44 and 52 degrees.

b) Contractor Controls Contractor to verify analog output can be provided to the chiller controls to reset chilled water setpoint. If additional hardware is needed to implement sequence, Contractor shall notify Owner and Engineer of Record through a RFI.

c) Controls Contactor to provide any additional input and output points needed on the DDC system, wiring, programming changes, and graphics display updates to fulfill the requirements of this Contract.

d) Sequencing of chiller stages shall be controlled by the internal controls on the chiller. DDC system shall provide the input and outputs listed on the drawing CSC-1-1.

B. Condenser Water Sequence shall follow the sequence listed on drawing CS-1-1 in the Johnson Controls Clark County Community Health Center Control Drawings dated 11/15/2004 and include the following modifications.


a) Once condenser water pumps are enabled set initial setpoint for condenser supply water temperature (CDSWT) to the chiller at 75 degrees.

1. Enable and control cooling tower fan speed through a PID control loop to maintain condense water supply temperature at setpoint.

2. After 15 minutes check CDWST and perform the following as needed. a. If the CDSWT does not reach the setpoint, and the VFD output has been above 95%

for the 15 minutes than increase the setpoint by 2 degrees b. If the VFD speed has been below 80% for the 15 minutes, reset the condenser water

temperature setpoint down 2 degrees. c. If the VFD speed falls between 95% and 80%, keep the setpoint the same as the last

iteration. 3. Set the maximum CDSWT setpoint to 78 degrees and the minimum to 65 degrees.

C. Freeze Protection Sequence for Chilled Water Pumps: Chilled Water Pump Control Sequence shall follow the sequence listed on drawing CS-1-1 in the Johnson Controls Clark County Community Health Center Control Drawings dated 11/15/2004 and include the following modifications.

A. Modify sequence so chilled water pumps are enabled when any of the following are true:

I. Chilled water plant is enabled when outside air temperature is above OSA enable setpoint.

II. Mixed air temperature (MAT) or supply air temperature (SAT) for any air handler drops below 45 degrees for more than 2 minutes.

III. Any air handler freeze protection is enabled. IV. When mixed air temperature or supply air temperature, or freeze protection event on any

air handler enables chilled water pumps, open chilled water valve for that AHU to 100%. V. When MAT or SAT for the air handler that went into freeze protection goes above 50

degrees the chilled water pumps shall be displayed and the chilled water valve for the air handler that went into freeze protection shall be released from 100%.

3.04 AIR HANDLERS (All Air Handlers) A. Operation for all air handlers shall follow the sequence listed on drawings appropriate for

each air handler in the Johnson Controls Clark County Community Health Center Control Drawings dated 11/15/2004 and include the following modifications.

Modification to the sequence shall include the following: B. Supply Static Pressure Setpoint (SSPS) Reset:

a) SSP shall be reset in a linear fashion through a PID control loop that monitors the damper positions for all the variable air terminal boxes served by the air handler and determine the Critical Zone (CZ), which is the zone with the terminal box with the damper that is open the most. When the CZ damper is open more than 95%, SSPS shall increase 0.2 in. wc of the previous setpoint. Damper position and reset shall be checked every 3 minutes. SSP shall be adjusted up until the CZ damper position is less than 95% open, or the static pressure setpoint has reached the maximum static pressure setpoint, or the supply fan VFD is at its maximum speed. When the damper for the CZ is less than 85% the static pressure will be reset down by 0.2 in wc of the previous setpoint. Damper position and reset shall be checked every 3 minutes. Static pressure setpoint shall be adjusted down until the CZ terminal box damper position is above 85% or the static pressure setpoint has reset to the minium static pressure setpoint of .75 in wc, or the supply fan VFD has reached its minimum setting.

b) Modify the box polling code to remove any rogue boxes that cannot be repaired and modified, and are inappropriately driving the reset sequences. Adjustments will be


made to the TU sample sequence during the testing of the sequence during commissioning.

c) Assume inspection and repair (TBD) of a maximum of six (6) terminal units that are identified as rogue boxes during commissioning of the revised reset sequences. It is recommended that an budget allowance be defined for each TU that represents a reasonable basis of budgeting.

C. Discharge Temperature Reset: a) Discharge Air Temperature (DAT) shall be reset in a linear fashion between 55 and 65

degrees based on outside air temperature and sampling of zone cooling requirements. b) During the occupied period, reset discharge temperature setpoint from T-min (53°F)

when the outdoor air temperature is 70°F and above, proportionally up to T-max when the outdoor air temperature is 60°F and below. T-max shall be reset using a PID control loop within the range 55°F to 65°F. When the fan is off, freeze T-max at the maximum value (65ºF). While fan is proven on, every 2 minutes, increase the setpoint by 0.2ºF if there are two (adjustable) or fewer zone cooling requests. If there are more than two (adjustable) cooling requests, decrease the setpoint by 0.3ºF. A cooling request is generated when the cooling loop of any zone served by the system is >99%.

c) Modify the box polling code to remove any rogue boxes that cannot be repaired and modified, and are inappropriately driving the reset sequences. Adjustments will be made to the TU sample sequence during the testing of the sequence during commissioning.

d) Assume inspection and repair (TBD) of a maximum of six (6) terminal units that are identified as rogue boxes during commissioning of the revised reset sequences. It is recommended that an budget allowance be defined for each TU that represents a reasonable basis of budgeting.

3.04 AIR HANDLERS (AHU-001 and AHU-002)

A. Operation for all air handlers shall follow the sequence listed on drawings appropriate for each air handler in the Johnson Controls Clark County Community Health Center Control Drawings dated 11/15/2004 and include the following modifications.

B. Outside, Return, and Exhaust Air Dampers: a) Economizer sequence shall utilize the outside damper assembly that has three separate

damper sections with separate actuators. Damper operation shall be staged. b) When economizer cooling is initiated, the section farthest from the air filter rack shall open

first, once that section is 100% open than the middle section of the OSA dampers shall modulate open. When the middle section is 100% open than the section closest to the air filters shall modulate open.

c) As economizer cooling is reduced, closing of the dampers shall occur in reverse to economizer cooling. Section closest to the filter rack shall modulate closed first. Once fully closed, the middle section shall modulate closed. Once the middle section is closed the section farthest from the filter rack shall modulate.

d) When the system outside air temperature is 1. When supply fan is not running, outside and relief dampers are closed and return damper

is open. 2. When supply fan is running, dampers are controlled and operate with outside and relief

dampers opening, and return damper closing. 3. For cooling and outside air temperatures below 55 degrees F, modulate dampers to

maintain mixed air temperature of 55 degrees F or higher. 4. For cooling and outside air temperatures above 55 degrees F outside and relief dampers

are open and return damper is closed.


5. For cooling and outside air temperatures above 55 degrees F compare return and outside air temperatures. If return air temperature is lower, drive outside damper to minimum, close relief damper, and open return damper.

6. For outside air temperatures above 79 degrees F, drive outside damper to minimum, close relief damper, and open return damper.

7. For heating, drive outside damper to minimum, close relief damper, and open return damper.

e) Modulate return and exhaust damper in such a way that the exhaust damper opens indirectly proportional to the return damper. Exhaust and return damper shall operate from the same analog output from the Johnson Controls Controller.

C. Building Static Pressure: Review and where needed modify sequence of operation for building static pressure so the static pressure shall be maintained at a steady 0.03 in wc. Sequence of operation shall include a PID control loop with input from the zone differential pressure sensor that is used for the exhaust fan speed control. Review differential pressure signal. If signal is erratic, investigate and make changes to the sensing points, sensor, and/or input configuration to create an accurate and steady signal. Verify and if needed make changes to the graphics and/or signal configuration to allow an accurate value to be displayed on the graphics screens. .
