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 SETPOINTS 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. SETPOINTS SPACE COOLING TEMPERATURE SETPOINTS: OCCUPIED: 75 °F +/- 1.5 °F OCCUPIED SETBACK: 75 °F + 3 °F UNOCCUPIED: 75 °F + 6 °F SPACE HEATING TEMPERATURE SETPOINTS: OCCUPIED: 75 °F +/- 1.5 °F OCCUPIED SETBACK: 75 °F - 3 °F UNOCCUPIED: 75 °F - 6 °F TOTAL EXHAUST AIR CHANGE RATE (ACPH): TYPICALLY = 8 ACPH OCC / 4 ACPH UNOCC 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 RATE + OFFSET FUME HOOD EXHAUST AIRFLOW RATE: NOT CONTROLLED BY BACS.

GENERAL EXHAUST AIRFLOW RATE (CFM): REFER TO AIRFLOW SCHEDULE TOTAL EXHAUST CFM - FUME HOOD EXHAUST CFM SPACE AIR DIFFERENTIAL OFFSET (CFM): REFER TO AIRFLOW SCHEDULE TYPICALLY = - 100 CFM FOR NEGATIVE PRESSURE LABS TYPICALLY = + 100 CFM FOR POSITIVE PRESSURE LABS FUME HOOD FACE VELOCITY: NOT CONTROLLED BY BACS. FACE VELOCITY SETPOINTS ARE PROGRAMMED INTO FUME HOOF 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 THE FUME HOOD SHALL BE EQUIPPED WITH A FUME HOOD MONITOR AND SASH POSITION INDICATOR. 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 VALVE. THE FUME HOOD MONITOR SHALL INDEX THE FUME HOOD EXHAUST AIR VALVE AS NEEDED TO MAINTAIN THE 100 FPM FACE VELOCITY SETPOINT BASED ON THE SASH POSITION. THE GENERAL EXHAUST AIR VALVE SHALL MODULATE AS NEEDED TO MAINTAIN THE OCCUPIED AIR CHANGE RATE. THE SUPPLY AIR VALVE SHALL MODULATE AS NEEDED TO MAINTAIN THE SPECIFIED AIRFLOW DIFFERENTIAL. WHEN THE ROOM IS UNOCCUPIED, AND THE SASH IS AT OR BELOW 18-INCHES, THE BACS SHALL SEND AN UNOCCUPIED COMMAND TO THE FUME HOOD EXHAUST AIR VALVE. THE FUME HOOD MONITOR SHALL INDEX THE FUME HOOD EXHAUST AIR VALVE AS NEEDED TO MAINTAIN THE 65 FPM FACE VELOCITY SETPOINT BASED ON THE SASH POSITION. THE GENERAL EXHAUST AIR VALVE SHALL MODULATE AS NEEDED TO MAINTAIN THE UNOCCUPIED AIR CHANGE RATE. THE SUPPLY AIR VALVE SHALL MODULATE AS NEEDED TO MAINTAIN THE SPECIFIED AIRFLOW DIFFERENTIAL WHEN THE ROOM IS UNOCCUPIED AND THE SASH IS ABOVE 18-INCHES BASED ON SASH POSITION, THE BACS SHALL NOT SEND THE SPACE UNOCCUPIED COMMAND TO THE FUME HOOD EXHAUST AIR VALVE. THE FUME HOOD MONITOR SHALL INDEX THE FUME HOOD EXHAUST AIR VALVE TO MAINTAIN THE UNOCCUPIED AIR CHANGE RATE. THE SUPPLY AIR VALVE SHALL MODULATE AS REQUIRED TO MAINTAIN THE SPECIFIED AIRFLOW DIFFERENTIAL. VACANT MODE: THE BACS SHALL SEND A DECOMMISSION COMMAND TO THE FUME HOOD EXHAUST AIR VALVE. THE FUME HOOD MONITOR SHALL INDEX THE FUME HOOD EXHAUST AIR VALVE TO CLOSE. THE GENERAL EXHAUST AIR VALVE SHALL MODULATE AS NEEDED 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 PROGRAMED SCHEDULE AND SPACE OCCUPANCY SENSORS. OCCUPIED HEATING: IF THE SPACE IS OCCUPIED DURING THE SCHEDULED OCCUPIED PERIOD AND THE SPACE TEMPERATURE FALLS BELOW THE OCCUPIED HEATING TEMPERATURE SETPOINT, THE REHEAT AND RADIANT PANEL CONTROL VALVES SHALL MODULATE IN PARALLEL TO MAINTAIN THE SPACE TEMPERATURE SETPOINT. WHEN THE SPACE TEMPERATURE IS AT SETPOINT, THE RADIANT PANEL AND REHEAT COIL CONTROL VALVES SHALL BE CLOSED. OCCUPIED COOLING: THE SPACE SHALL HAVE A FAN COIL UNIT TO PROVIDE SUPPLEMENTAL SPACE COOLING. IF THE SPACE IS OCCUPIED DURING THE SCHEDULED OCCUPIED PERIOD AND THE SPACE TEMPERATURE RISES ABOVE THE OCCUPIED COOLING TEMPERATURE SETPOINT, THE FAN COIL UNIT FAN SHALL START, AND THE COOLING COIL CONTROL VALVE SHALL MODULATE TO MAINTAIN SETPOINT. WHEN THE SPACE TEMPERATURE IS AT SETPOINT, THE FAN COIL UNIT SHALL SHUT OFF AND THE CHILLED WATER CONTROL VALVE SHALL CLOSE. OCCUPIED SETBACK: IF THE SPACE BECOMES UNOCCUPIED DURING THE SCHEDULED OCCUPIED 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 AND THE SPACE TEMPERATURE FALLS BELOW THE UNOCCUPIED HEATING TEMPERATURE SETPOINT, THE REHEAT AND RADIANT PANEL CONTROL VALVES SHALL MODULATE IN PARALLEL TO MAINTAIN THE SPACE TEMPERATURE SETPOINT. UNOCCUPIED COOLING: IF THE SPACE IS UNOCCUPIED DURING THE SCHEDULED UNOCCUPIED PERIOD AND THE ZONE TEMPERATURE RISES ABOVE THE UNOCCUPIED COOLING TEMPERATURE SETPOINT, THE FAN COIL UNIT SHALL START, AND THE FAN COIL UNIT COOLING CONTROL VALVE SHALL MODULATE TO MAINTAIN SETPOINT. 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. VACANT MODE: THE ABOVE UNOCCUPIED HEATING/COOLING SEQUENCES SHALL APPLY. THE SPACE SHALL BE MAINTAINED AT THE UNOCCUPIED TEMPERATURE SETPOINTS. THE COOLING COIL CONTROL VALVE SHALL BE CLOSED WHENEVER THE HEATING COIL CONTROL VALVE IS OPEN TO PREVENT SIMULTANEOUS HEATING AND COOLING. THE COOLING CONTROL VALVE SHALL BE CLOSED WHEN THE FAN COIL UNIT FAN IS OFF.
