01234 – Landscaping Requirements
Section 01234 Landscaping Requirements a. Plant Selection: At all properties, landscaping priority shall be the use of xerographic plants native to the upper Gulf Coast of Texas and adjacent northern counties or plants that can tolerate or thrive in both drought and heavy rain conditions. For properties north of an east west line paralleling Little York Road, plants shall also be able to survive a “hard freeze”, i.e. temperatures at or below 32° F for six or more hours. b. Irrigation Systems: Only Drip Irrigation systems shall be used in bedding areas for trees, bushes, shrubs, herbs and flowers. Pop-up sprinklers for lawn and turf irrigation shall use high density polyethylene (HDP) flexible pipe risers and HDP, insert-ell, threaded fittings. Only HDP insert ells with a self-locking ridge and spiral barbs designed for flexible HDP pipe shall be used on the HDP risers. An acceptable alternative to the HDP riser is the preassembled swing riser with PVC ells having o-ring sealed swivels built into them. During installation the pipe shall not be bent to position the sprinkler (HDP has “memory” and will return to its original shape, pulling the sprinkler along with it causing the sprinkler head to tilt at an unwanted angle). The length of flexible pipe used for risers shall be of no greater length than 15 inches. Lengths greater than 15 inches result in an unacceptable pressure loss. Sprinkler heads shall not be positioned within 6 inches to curbs, walkways and landscape borders.

Each building c. Each floor and zone controlled F. Zone Setpoint Adjustments Color floor plans displayed via a web browser shall utilize a contiguous band of colors, each corresponding to actual zone temperatures relative to the desired heating and cooling setpoints. The ideal temperature shall be shown as a green color band. Temperatures slightly warmer than ideal shall be shown in yellow and even warmer temperature band shall be shown in orange. Temperatures slightly cooler than ideal shall be light blue, and even cooler temperatures shall be shown as dark blue. All alarm colors shall be in red. 1. Active Zone Graphic Setpoint Controls: Utilizing a mouse, it shall be possible to select occupied or unoccupied setpoints (corresponding to the floor plan colors) and drag the color slide bar(s) to increase or decrease heating and cooling setpoints. In addition to the slide bars, an operator may type the numeric value of the heating and cooling setpoints. The floor plan graphic shall then change colors on a zone-by-zone basis to reflect the actual temperature in each zone relative to the changed heating or cooling setpoint. G. Hierarchical Schedules Utilizing the Navigation Tree displayed in the web browser GUI, an operator (with password access) shall be able to define a Normal, Holiday or Override schedule for an individual piece of equipment or room, or choose to apply a hierarchical schedule to the entire system, site or floor area. For example, Independence Day ‘Holiday’ for every level in the system would be created by clicking at the top of the geographic hierarchy defined in the Navigation Tree. No further operator intervention would be required and every control module in the system with would be automatically downloaded with the ‘Independence Day’ Holiday. All schedules that affect the system/area/equipment highlighted in the Navigation Tree shall be shown in a summary schedule table and graph. DDC Automatic Temperature Controls / Energy Management System
1. BACnet Schedules: Schedules shall comply with the BACnet standard, (Schedule Object, Calendar Object, Weekly Schedule property and Exception Schedule property) and shall allow events to be scheduled based on: a.

Any combination of Month of Year (1-12, any), Week of Month (1-5, last, any), Day of Week (M-Sun, Any) e. Wildcard (example, allow combinations like second Tuesday of every month). 2. Schedule Categories: The system shall allow operators to define and edit scheduling categories (different types of “things” to be scheduled; for example, lighting, HVAC occupancy, etc.). The categories shall include: name, description, icon (to display in the hierarchy tree when icon option is selected) and type of value to be scheduled. 3. Scheduled Groups: In addition to hierarchical scheduling, operators shall be able to define functional Schedule Groups, comprised of an arbitrary group of areas/rooms/equipment scattered throughout the facility and site. For example, the operator shall be able to define an ‘individual tenant’ group – who may occupy different areas within a building or buildings. Schedules applied to the ‘tenant group’ shall automatically be downloaded to control modules affecting spaces occupied by the ‘tenant group’. 4. Intelligent Scheduling: The control system shall be intelligent enough to automatically turn on any supporting equipment needed to control the environment in an occupied space. If the operator schedules an individual room in a VAV system for occupancy, for example, the control logic shall automatically turn on the VAV air handling unit, chiller, boiler, and/or any other equipment required to maintain the specified comfort and environmental conditions within the room. 5. Partial Day Exceptions: Schedule events shall be able to accommodate a time range specified by the operator (ex: board meeting from 6 pm to 9 pm overrides Normal schedule for conference room). 6. Schedule Summary Graph: The schedule summary graph shall clearly how Normal versus Holiday versus Override Schedules, and the net operating schedule that results from all contributing schedules. Note: In case of priority conflict between schedules at the different geographic hierarchy, the schedule for the more detailed geographic level shall apply. 7. Schedule Distribution: For reliability and performance, instead of maintaining a single schedule in a field device that writes over the network to notify other devices when a scheduled event occurs, field devices will only keep their part of the schedule locally. The BAS server software shall determine which nodes a hierarchical schedule applies to and will create/modify the necessary schedule objects in each field device as necessary. H. Events (& Alarms) Events and alarms associated with a specific system, area, or equipment selected in the Navigation Tree, shall be displayed in the Action Pane by selecting an ‘Events’ view. Events, alarms, and reporting actions shall have the following capabilities:

2.03 GRAPHICAL PROGRAMMING The system software shall include a Graphic Programming Language (GPL) for all DDC control algorithms resident in standalone control modules. Any system that does not use a drag and drop method of graphical icon programming as described herein is NOT acceptable. GPL is a method used to create a sequence of operations by assembling graphic microblocks that represent each of the commands or functions necessary to complete a control sequence. Microblocks represent common logical control devices used in conventional control systems, such as relays, switches, high signal selectors, etc., in addition to the more complex DDC and energy management strategies such as PID loops and optimum start. Each microblock shall be interactive and contain the programming necessary to execute the function of the device it represents. Graphic programming shall be performed while on screen and using a mouse; each microblock shall be selected from a microblock library and assembled with other microblocks necessary to complete the specified sequence. Microblocks are then interconnected on screen using graphic "wires," each forming a logical connection. Once assembled, each logical grouping of microblocks and their interconnecting wires then forms a graphic function block which may be used to control any piece of equipment with a similar point configuration and sequence of operation. A. Graphic Sequence The clarity of the graphic sequence must be such that the operator has the ability to verify that system programming meets the specifications, without having to learn or interpret a manufacturer's unique programming language. The graphic programming must be selfdocumenting and provide the operator with an understandable and exact representation of each sequence of operation. B. Simulation Full simulation capability shall be provided with the graphic programming. Operator shall be able to fully simulate the constructed control sequence prior to downloading into field control modules. Simulation capabilities shall include step-by-step, accelerated time, and operator defined simulation criteria like outside weather, demand, and communication status. Multiple graphic programs shall be simulated and displayed in split screens at the same time. DDC Automatic Temperature Controls / Energy Management System
C. GPL Capabilities The following is a minimum definition of the capabilities of the Graphic Programming software: 1. Function Block (FB): Shall be a collection of points, microblocks and wires which have been connected together for the specific purpose of controlling a piece of HVAC equipment or a single mechanical system. 2. Logical I/O: Input/Output points shall interface with the control modules in order to read various signals and/or values or to transmit signal or values to controlled devices. 3. BACnet Points: Shall be points that comply with the BACnet structure as defined in the BIBB’s Addendum B1/B2, and the BACnet standard. 4. Microblocks: Shall be software devices that are represented graphically and may be connected together to perform a specified sequence. A library of microblocks shall be submitted with the control contractors bid. 5. Wires: Shall be Graphical elements used to form logical connections between microblocks and between logical I/O. Different wires types shall be used depending on whether the signal they conduct is analog or digital. 6. Labels: Labels shall be similar to wires in that they are used to form logical connections between two points. Labels shall form a connection by reference instead of a visual connection, i.e. two points labeled 'A' on a drawing are logically connected even though there is no wire between them. 7. Parameter: A parameter shall be a value that may be tied to the input of a microblock. 8. Properties: Dialog boxes shall appear after a microblock has been inserted which has editable parameters associated with it. Default parameter dialog boxes shall contain various editable and non-editable fields and shall contain 'push buttons’ for the purpose of selecting default parameter settings. 9. Icon: An icon shall be graphic representation of a software program. Each graphic microblock has an icon associated with it that graphically describes it function. 10. Menu-bar Icon: Shall be an icon that is displayed on the menu bar on the GPL screen, which represents its associated graphic microblock. 11. Live Graphical Programs: The Graphic Programming software must support a ‘live’ mode, where all input/output data, calculated data, and set points shall be displayed in a ‘live’ real-time mode. For each piece of HVAC equipment, the entire graphic program shall be displayed through the Web Browser GUI. The operator must have the ability to scroll through the entire ‘live’ graphic program as necessary. Piecemeal graphic programs that only show one part of HVAC equipment program at any one time are NOT acceptable. For example, when viewing an AHU live graphic program, the operator shall see the entire AHU graphic program, not just the Heating Coil control.

Dated schedules shall be entered up to 9 (nine) years in advance. 3. Self-Deleting. Schedules shall be self-deleting when effective dates have passed.
DDC Automatic Temperature Controls / Energy Management System
4. Leap Year. Leap years shall be adjusted automatically without operator intervention. B. Optimum Start/Stop (OSS) / Optimum Enable/Disable (OED) This application provides software to start and stop equipment on a sliding schedule based on the individual zone temperature and the heating/cooling capacity in °F/hour of the equipment serving that zone. The heating/cooling capacity value shall be operator adjustable. Temperature compensated peak demand limiting shall remain in effect during morning start up to avoid setting a demand peak. C. Source Temperature Optimization (STP) The system shall automatically perform source optimization for all air handling units, chillers and boilers in response to the needs of other downstream pieces of equipment, by increasing or decreasing supply temperature setpoints, i.e. chilled water, discharge air, etc. using owner defined parameters. In addition to optimization, the STO capability shall also provide for starting and stopping primary mechanical equipment based on zone occupancy and/or zone load conditions. 1. Setpoint Reset. The STO program will allow setpoints for various equipment in the heating/cooling chain to be reset between an operator defined maximum and a minimum setpoint based on the actual requirements of the building zones. The actual setpoint shall be calculated based on the number of heating or cooling requests which are currently being received from the equipment or zones served. Once every update period, the STO program surveys the network to see if any piece of equipment requires any additional heating or cooling from its source. As an example, a VAV air handler is the source of cold air for a number of VAV boxes. Assume that the STO program for the air handler has the following parameters established for it by the owner: Optimized setpoint description – a. Initial setpoint is 60.00, b. Maximum setpoint is 65.00, c. Minimum setpoint is 55.00. d. Every 2.0 minutes, trim by 0.25 and respond by -0.50 but no more than 2.0. Every two minutes, the STO program will total up all of the requests and calculate a new setpoint: New setpoint = prev setpoint + 'trim by' + ('respond by' x no. of req.). Assuming four requests were received and the previous setpoint was 57.00 degrees, the new setpoint would be: New setpoint = 57.00 + 0.25 + (-0.50 x 4) = 55.25 Deg F If (the number of requests received) x (the 'respond by' value) > (the 'but no more than' value), use the 'but no more than' value inside the parenthesis in the above calculation.

Equipment shall not be shed if these reset setpoints are not satisfied; rather the setpoint shall be revised for the different established demand levels. The system shall have failed meter protection, such that when a KW pulse is not received from the utility within an operator adjustable time period, an alarm will be generated. The system software will automatically default to a predetermined failsafe shed level. 3. Information Archiving. The system shall have the ability to archive demand and usage information for use at a later time. System shall permit the operator access to this information on a current day, month to date and a year to date basis. E. Day/Night Setback (DNS) The system shall allow the space temperature to drift down [up] within a preset [adjustable] unoccupied temperature range.

The system shall turn the equipment ON upon receiving a request from the local input device. Local input devices shall be push button (momentary contact), wind-up timer, or ON/OFF switches as detailed in the I/O summary. G. Space Temperature Control (STC) There shall be two space temperature setpoints, one for cooling and one for heating, separated by a dead band. Only one of the two setpoints shall be operative at any time. The cooling setpoint is operative if the actual space temperature has more recently been equal to or greater than the cooling setpoint. The heating setpoint is operative if the actual space temperature has more recently been equal to or less than the heating setpoint. There are two modes of operation for the setpoints, one for the occupied mode (example: heating = 72°F or 22°C, cooling = 76°F or 24.4°C) and one for the unoccupied mode (example: heating = 55°F or 12.7°C, cooling = 90°F or 32°).
DDC Automatic Temperature Controls / Energy Management System
1. Schedule. The occupied/unoccupied modes may be scheduled by time, date, or day of week. 2. Color Code. One of seven colors shall be generated to represent the comfort conditions in the space, and shall be displayed graphically at the operator station. a. If the actual space temperature is in the dead band between the heating setpoint and the cooling setpoint, the color displayed shall be green for the occupied mode, representing ideal comfort conditions. If in the unoccupied mode, the color displayed shall be gray representing 'after-hours' conditions. b. If the space temperature rises above the cooling setpoint, the color shall change to yellow.

At this point an alarm shall be generated to notify the operator. c. When space temperature falls below the heating setpoint, the color shall change to light blue. Upon further temperature decrease below the heating setpoint minus an offset, the color shall change to dark blue. Upon further space temperature decrease below the heating setpoint minus the light blue band offset minus the dark blue band offset the color shall change to red indicating unacceptable low temperature conditions. At this point an alarm shall be generated to notify the operator. 3. Operator Definable. All setpoints and offsets shall be operator definable. When in the occupied mode, start-up mode, or when heating or cooling during the night setback unoccupied mode, a request shall be sent over the network to other equipment in the HVAC chain, such as to an AHU fan that serves the space, to run for ventilation. The operator shall be able to disable this request function if desired. 4. Additional Cooling. When comfort conditions are warmer than ideal, indicated by the colors yellow, orange, and high temperature red, a request for additional cooling shall be sent over the network to other cooling equipment in the HVAC chain, such as a chiller. This information is to be used for optimization of equipment in the HVAC chain. The operator shall be able to disable this function if desired. 5. Additional Heating. When comfort conditions are cooler than ideal; indicated by the colors light blue, dark blue and low temperature red; a request for additional heating shall be sent over the network to other heating equipment in the HVAC chain, such as a boiler. This information is to be used for optimization of equipment in the HVAC chain. The operator shall be able to disable this function if desired. 6. Cooling/Heating Setpoints. The cooling [and heating] setpoints maybe increased [decreased] under demand control conditions to reduce the cooling (heating) load on the building during the demand control period. Up to three levels of demand control strategy shall be provided. The operator may predefine the amount of setpoint increase [decrease] for each of the three levels. Each space temperature sensor in the building may be programmed independently. 7. Optimum Start. An optimum start-up program transitions from the unoccupied setpoints to the occupied setpoints. The optimum start-up algorithm considers the rate of space temperature rise for heating and the rate of space temperature fall for cooling under nominal outside temperature conditions; it also considers the outside

temperature; and the heat loss and gain coefficients of the space envelope (AI: Space Temperature). 8. PID Loop. A PID control loop, comparing the actual space temperature to its setpoint, shall modulate the dampers [and heating coil valve or heating stages in sequence] to achieve the setpoint target.
PART 6 – SEQUENCES OF OPERATION A. Chilled Water System. 1. The chilled water system will be activated by a request for cooling from any air handler supplied with chilled water being controlled through the B.A.S. 2. When the chilled water system is activated, the chiller manager will send a run request to the lead (110) ton chiller. The B.A.S. will start the lead chilled water pump. A differential pressure switch across the pump will prove status to the B.A.S. Control Module and will alarm at the Central Site if the switch is not made within 20 seconds (adjustable). There will also be a 20 second (adjustable) de-bounce time to prevent nuisance alarms from a bouncing pressure switch. When chilled water pump status has been proven for 1 minute(adjustable), the B.A.S. will send a 24 VAC signal to a relay mounted at the chiller control cabinet which will complete the start circuit and allow the chiller to run. A flow switch in the chilled water line will not allow the chiller to start until the pump has been started and flow has been proven. If the lead chiller fails to start within 2 minutes (adjustable), the B.A.S. will shut off its chilled water pump, alarm the Central Site and automatically start a lag (30) ton chiller and lag pump. 3. When the lad chiller has started, the B.A.S. will receive temperature inputs from sensors mounted in the chilled water supply and return piping. After 15 minutes (adjustable), if the chilled water supply temperature rises above 46º F (adjustable), the B.A.S. will send a run request to the (30) ton lag chiller control program. The lag chiller and chilled water pump will be started and controlled in the same manner as the lead chiller. 4. When the chilled water return temperature reaches 49º F (adjustable), the run request to a (30) ton chiller will be canceled. The lag chiller will continue to run for 10 minutes (adjustable) and will then be stopped. Its chilled water pump will continue to run for 5 minutes (adjustable) to insure adequate flow during shutdown. When the lead chiller has started, the B.A.S. will calculate the BTUs being used by receiving temperature inputs from sensors mounted in the chilled water supply and return piping, and a flow meter in the chilled water supply. After 10 minutes (adjustable), if the BTUs being used are greater than 95% (adjustable) of the capacity of the lead chiller, a run request will be sent to the lag chiller. The lag chiller and pumps will be started as described above. As the building load decreases to 80% (adjustable) of the capacity of lead chiller for 5 minutes (adjustable), the run request to the lag chiller will be canceled. Ten minute (adjustable) time delays will be assigned to each chiller start/stop circuit to prevent short cycling. 5. A differential pressure sensor will measure the pressure differential between the chilled water supply and chilled water return. The differential pressure sensor will be used to modulate the bypass flow control valve to maintain the required building pressure.

6. The B.A.S. Control Module will reset the chilled water supply temperature between 42º F and 49º F (adjustable) depending on the number of requests for cooling and their duration. 7. When the chilled water system is inactive, all chillers and chilled water pumps will be off. If the outside air temperature drops below 40º F (adjustable), the B.A.S. start the lead chilled water pumps for freeze protection. B. Hot Water System. 1. The heating water system will be activated by a request for heat from any air handler or terminal unit supplied with heating water and controlled through the B.A.S. 2. When a request for heating is received, the B.A.S. will send a signal to start the pump. A differential pressure switch across the pump will prove status to the B.A.S. and will alarm at the Central Site if the switch is not made within 20 seconds (adjustable). There will also be a 20 second (adjustable) de-bounce time to prevent nuisance alarms from a bouncing. 3. When the boiler is deactivated, the heating water pump will continue to run for three minutes (adjustable) to avoid excessive pressure build-up in the boiler. The lead/lag sequence will be operator assigned to alternate the pumps weekly. Ten minute (adjustable) time delays will be assigned to each heating water pump start/stop to prevent short cycling. 4. B.A.S. will send a 24 VAC signal to a remote relay interfaced with the boiler control circuit which will enable the boiler to fire. If the lead boiler is de-energized by any of its internal safeties, the B.A.S. will alarm the Central Site. 5. The B.A.S. Control Module will receive temperature inputs from sensors located in the building’s hot water supply and return piping. The B.A.S. will modulate the mixing valve to maintain the hot water supply setpoint. The hot water supply setpoint shall be reset between 140º F and 180º F based on an outdoor air temperature of65º F to 40º F respectively (all values adjustable). 6. When incoming requests for heating are less than five minutes (adjustable), the boilers will be deactivated and the mixing valve willfully open to the boiler to provide a cool-down period. 7. When the boiler is inactive, a shutdown will be broadcast on the network to indicate that heating water is not available. A normal condition will be broadcast whenever the heating water supply temperature is greater than 100º F (adjustable) and the heating water pump has an ON status. 8. When the heating water system is inactive, the boiler enable circuits will not allow the boiler to fire, the heating water pump will be off and the mixing valve will be open to the boiler. If the outdoor air temperature drops below 40º F (adjustable), the B.A.S. will energize the heating water pump for freeze protection. C. VAV Air Handler. 1. Each VAV air handling unit will be activated by a request to run from any CVB terminal unit it serves. 2. A run request will be sent to the chilled water system when the air handling unit is active. The discharge air temperature will be monitored by a duct-mounted temperature sensor. The B.A.S. will modulate the chilled water control valve as required to maintain the discharge air temperature setpoint of 55º F (adjustable).

3. The B.A.S. Control Module will receive inputs from a static pressure sensor located at the midpoint of the duct run. The B.A.S. will send a 0-10 VDC signal to the inverter which will adjust the speed of the air handler fan motor to maintain the required pressure setpoint of 1.5" (adjustable). 4. During the occupied time period, the outside air damper associated with the air handling unit will be open and any related exhaust fans will be energized. 5. When the air handling unit is de-energized, its chilled water valve and outside air damper will be closed, and any related exhaust fans will be de-energized. 6. A duct temperature sensor shall be located in the mixed air stream. If the mixed air temperature drops below a designated setpoint, the outdoor air damper shall close and the unit shall be energized. The chilled water coil shall be modulated full open for freeze protection. D. Fan Powered Terminal Boxes. 1. Each CV terminal unit will have an occupancy/vacancy schedule, occupied heating/cooling setpoints, and unoccupied heating/cooling setpoints assigned to it. As the occupancy time approaches, an optimum start/stop program will calculate a start time based on current space temperature verses the occupied heating or cooling setpoint, assigned recovery rate, and outdoor air temperature. 2. When the zone becomes occupied, the terminal unit fan will be energized and run to provide constant air volume to the space. 3. If cooling is required, a P.I.D. control loop will modulate the terminal unit damper from its minimum CFM setpoint (adjustable) to its full open position as required to maintain the space temperature. As the space temperature returns to setpoint, the terminal unit damper will be modulated to its minimum CFM setpoint. 4. If heating is required, a run request will be sent to the heating water system. The terminal unit damper will be maintained at its minimum CFM setpoint (adjustable) and the hot water reheat v valve will be modulated to maintain the space temperature. 5. During unoccupied periods, the terminal unit damper and hot water reheat valve will be closed. E. Miscellaneous Control: 1. Furnish and install a firestat for each exhaust and ventilating fan handling 200 CFM or more. These shall be manual reset devices which shall “break” line voltage contact as the air temperature reaches a pre-determined level. Contact rating shall be 5 amps at 240 VAC. 2. Smoke detectors shall be furnished and installed by Mechanical Contractor in supply air on all air handling units. AHU fan shall be de-energized upon detection of products of combustion. This hardwired interlock to be done by Division 16. 3. Interlock fans with respective AHU unless noted on prints.
