ALL POINTS WITHIN EACH ZONE MUST BE CONNECTED DIRECTLY TO A LOCAL CONTROLLER. TO ENSURE ZONES CAN OPERATE INDEPENDENTLY, DEVICES SHALL NOT RELY ON NETWORK TO COMMUNICATE ACROSS ZONES. SYSTEM SHALL BE CONTROLLED THROUGH THE BUILDING AUTOMATION AND CONTROL SYSTEM (BACS). ALL SET POINTS SHALL BE ADJUSTABLE. THE BACS SHALL BE CAPABLE OF RETAINING ITS PROGRAMMING AND TIME SETTING DURING A LOSS OF POWER FOR AT LEAST TEN HOURS. LABORATORY AIR CHANGE RATES ARE BASED ON TOTAL EXHAUST AIR FLOW FROM THE SPACE. THE SPACE SHALL BE CONTROLLED TO AN AIR CHANGE RATE. THE BACS SHALL CALCULATE THE REQUIRED CFM USING THE ROOM GROSS VOLUME (AREA x CEILING HEIGHT). DESIGN INTENT: THIS SEQUENCE IS FOR LABORATORIES IN WHICH THE DRIVING FACTOR IS THE EXHAUST AIR FLOW IN SUPPORT OF THE FUME HOODS. SETPOINTS SPACE COOLING TEMPERATURE SETPOINTS: OCCUPIED: 75 DEG F +/- 1.5 DEG F OCCUPIED SETBACK: 75 DEG F + 3 DEG F UNOCCUPIED: 75 DEG F + 6 DEG F SPACE HEATING TEMPERATURE SEPOINTS: OCCUPIED: 70 DEG F +/- 1.5 DEG F OCCUPIED SETBACK: 70 DEG F - 3 DEG F UNOCCUPIED: 70 DEG F - 6 DEG F TOTAL EXHAUST AIR CHANGE RATE (ACPH): REFER TO AIRFLOW SCHEDULE ACPH = TOTAL EXHAUST CFM x 60/ROOM VOLUME TOTAL EXHAUST AIRFLOW RATE (CFM): REFER TO AIRFLOW SCHEDULE SUPPLY AIRFLOW RATE (CFM): REFER TO AIRFLOW SCHEDULE TYPICALLY = TOTAL EXHAUST AIRFLOW RATE + OFFSET FUME HOOD FACE VELOCITY: NOT CONTROLLED BY BACS. FACE VELOCITY SETPOINTS ARE PROGRAMMED INTO FUME HOOD MONITOR. TYPICALLY 100 FPM OCC / 65 FPM UNOCC. MINIMUM LABORATORY OCCUPANCY INDEX TIME: 30 MINUTES ZONE OCCUPANCY SCHEDULE: 6 AM TO 8 PM MON-FRI FACE VELOCITY CONTROL EACH FUME HOOD SHALL BE EQUIPPED WITH A FUME HOOD MONITOR AND SASH POSITION INDICATOR. THE MONITOR SHALL ADJUST THE FUME HOOD EXHAUST VALVE TO MAINTAIN THE FACE VELOCITY SETPOINT. THE MONITOR SHALL, AS A MINIMUM, HAVE THE FOLLOWING CAPABILITIES: - SASH POSITION INPUT. - STANDBY MODE INPUT TO ALLOW ADJUSTMENT OF FACE VELOCITY. - HOOD DECOMMISSION MODE. LABORATORY AIRFLOW CONTROL AIR VALVE POSITIONS SHALL BE BASED ON MODE. UNDER NORMAL CONTROL, ROOM OCCUPANCY SHALL BE DETERMINED VIA ROOM OCCUPANCY SENSORS (MINIMUM 2 PER LAB USING LIGHTING OCCUPANCY SENSOR AUXILIARY CONTACTS). IF THE LABORATORY IS VACANT, THE ROOM SHALL BE PLACED IN VACANT MODE BY THE BACS. WHEN THE ROOM IS OCCUPIED, THE BACS SHALL SEND AN OCCUPIED COMMAND TO THE FUME HOOD EXHAUST AIR VALVES. THE FUME HOOD MONITORS SHALL INDEX THE FUME HOOD EXHAUST VALVES BETWEEN THE MINIMUM AND MAXIMUM POSITIONS AS NEEDED TO MAINTAIN THE 100 FPM FACE VELOCITY SETPOINT BASED ON THE SASH POSITION. THE SUPPLY AIR VALVE SHALL MODULATE AS NEEDED TO MAINTAIN THE SPECIFIED AIRFLOW DIFFERENTIAL. WHEN THE ROOM IS UNOCCUPIED, AND THE SASHES ARE AT OR BELOW 18-INCHES, THE BACS SHALL SEND AN UNOCCUPIED COMMAND TO THE FUME HOOD EXHAUST AIR VALVES. THE FUME HOOD MONITORS SHALL INDEX THE FUME HOOD EXHAUST AIR VALVES AS NEEDED TO MAINTAIN THE 65 FPM FACE VELOCITY SETPOINT BASED ON THE SASH-POSITION. THE SUPPLY AIR VALVE SHALL MODULATE AS NEEDED TO MAINTAIN THE SPECIFIED AIRFLOW DIFFERENTIAL. WHEN THE ROOM IS UNOCCUPIED AND ANY OF THE FUME HOOD SASHES ARE ABOVE 18-INCHES, THE BACS SHALL NOT SEND THE SPACE UNOCCUPIED COMMAND TO THOSE PARTICULAR FUME HOOD EXHAUST AIR VALVES. THE FUME HOOD MONITOR SHALL INDEX THE FUME HOOD EXHAUST AIR VALVES WHOSE SASHES ARE ABOVE 18-INCHES TO MAINTAIN THE OCCUPIED SASH OPEN AIRFLOW SETPOINT. THE BACS WILL SEND THE UNOCCUPIED COMMAND TO THOSE FUME HOOD MONITORS SHALL INDEX THE FUME HOOD EXHAUST AIR VALVES WHOSE SASHES ARE AT 18-INCHES AND BELOW TO MAINTAIN THE 65 FPM FACE VELOCITY SETPOINT. THE SUPPLY AIR VALVE SHALL MODULATE AS REQUIRED TO MAINTAIN THE SPECIFIED AIRFLOW DIFFERENTIAL. VACANT MODE: THE BACS SHALL SEND A DECOMMISSION COMMAND TO EACH FUME HOOD EXHAUST AIR VALVE. THE FUME HOOD MONITOR SHALL INDEX THE FUME HOOD EXHAUST AIR VALVE TO CLOSE. ONE OF THE FUME HOOD EXHAUST AIR VALVES SHALL BE SET UP TO OPERATE AS A GENERAL EXHAUST VALVE DURING VACANCY MODE, AND SHALL INDEX TO MAINTAIN THE VACANT AIR CHANGE RATE. THE SUPPLY AIR VALVE SHALL MODULATE AS REQUIRED TO MAINTAIN THE SPECIFIED AIRFLOW DIFFERENTIAL. ZONE TEMPERATURE CONTROL TEMPERATURE SETPOINTS SHALL BE DETERMINED BASED ON A COMBINATION OF PROGRAMMED SCHEDULE AND SPACE OCCUPANCY SENSORS. IF OUTSIDE AIR TEMPERATURE IS BELOW 50°F AND SV REHEAT COIL CONTROL VALVE IS NOT FULLY CLOSED, HOT WATER CONTROL VALVE FCV-01 SHALL FULLY OPEN. OCCUPIED HEATING: IF THE SPACE IS OCCUPIED DURING THE SCHEDULED OCCUPIED PERIOD AND THE ZONE TEMPERATURE FALLS BELOW THE OCCUPIED HEATING TEMPERATURE SETPOINT, THE REHEAT AND CEILING RADIANT PANEL CONTROL VALVE(S) SHALL MODULATE IN PARALLEL TO MAINTAIN THE SPACE TEMPERATURE SETPOINT. WHEN THE SPACE TEMPERATURE IS AT SETPOINT, THE REHEAT COIL CONTROL VALVE(S) SHALL BE CLOSED. OCCUPIED COOLING: IF THE SPACE IS OCCUPIED DURING THE SCHEDULED OCCUPIED PERIOD AND THE SPACE TEMPERATURE RISES ABOVE THE OCCUPIED COOLING TEMPERATURE SETPOINT, THE REHEAT CONTROL VALVE(S) SHALL CLOSE. IF TEMPERATURE IS ABOVE SETPOINT AND REHEAT CONTROL VALVE(S) ARE FULLY CLOSED, GENERAL EXHAUST AIRFLOW SETPOINT SHALL MODULATE TO MAINTAIN SPACE TEMPERATURE SETPOINT. OCCUPIED SETBACK: IF THE SPACE BECOMES UNOCCUPIED DURING THE SCHEDULED OCCUPANCY PERIOD, THE ABOVE OCCUPIED HEATING/COOLING SEQUENCES SHALL APPLY, BUT THE SPACE SHALL BE MAINTAINED AT THE OCCUPIED SETBACK TEMPERATURE SETPOINTS. UNOCCUPIED HEATING: IF THE SPACE IS UNOCCUPIED DURING THE SCHEDULED UNOCCUPIED PERIOD, THE ABOVE OCCUPIED HEATING/COOLING SEQUENCES SHALL APPLY, BUT THE SPACE SHALL BE MAINTAINED AT THE OCCUPIED SETBACK TEMPERATURE SETPOINTS. UNOCCUPIED COOLING: IF THE SPACE IS UNOCCUPIED DURING THE SCHEDULED UNOCCUPIED PERIOD AND THE SPACE TEMPERATURE RISES ABOVE THE UNOCCUPIED COOLING TEMPERATURE SETPOINT, THE REHEAT COIL CONTROL VALVE(S) SHALL CLOSE. IF THE SPACE BECOMES OCCUPIED DURING THE SCHEDULED UNOCCUPIED PERIOD, THE SPACE SHALL INDEX TO OCCUPIED MODE FOR THE DURATION OF OCCUPANCY. WHEN THE SPACE BECOMES UNOCCUPIED AGAIN DURING THE SCHEDULED UNOCCUPIED PERIOD, THE SPACE SHALL INDEX BACK TO UNOCCUPIED MODE.
