FURNACE CONTROL SEQUENCE:

OCCUPIED MODE:

THE GAS FURNACE SHALL BE CONTROLLED BY A 7-DAY PROGRAMMABLE THERMOSTAT. THE SUPPLY FAN SHALL RUN CONTINUOUSLY DURING OCCUPIED HOURS. THE PROGRAMMABLE THERMOSTAT SHALL CYCLE ON THE GAS

HEAT EXCHANGER AS REQUIRED TO MAINTAIN HEATING SETPOINT (70°F - ADJUSTABLE).

WHEN THE SUPPLY FAN RUNS, THE OUTSIDE AIR DAMPER SHALL OPEN TO PROVIDE THE SCHEDULE OUTSIDE AIR

TO THE SPACE.

WHEN THE OUTSIDE AIR TEMPERATURE IS ABOVE 70°F (ADJUSTABLE), THE ECONOMIZER MIXING BOX CONTROLLER SHALL MODULATE THE OA AUTOMATIC DAMPER OPEN AND THE RA AUTOMATIC DAMPER

OPEN/CLOSED AS REQUIRED TO MAINTAIN HEATING SETPOINT (70°F - ADJUSTABLE).

UNOCCUPIED MODE:

THE PROGRAMMABLE THERMOSTAT SHALL CYCLE ON THE SUPPLY FAN AND GAS HEAT EXCHANGER TO MAINTAIN THE UNOCCUPIED HEATING SETPOINT (55°F - ADJUSTABLE). THE OUTSIDE AIR DAMPERS SHALL REMAIN

CLOSED DURING UNOCCUPIED HOURS.

DEMAND CONTROLLED VENTILATION:

THE OUTSIDE AIR DAMPER SHALL BE CONTROLLED VIA THE ECONOMIZER/DCV CONTROL MODULE (BASIS OF

DESIGN - HONEYWELL JADE W7220).

WHEN SPACE CO2 SENSOR DETECTS CO2 LEVELS BELOW SETPOINT OF 1,100PPM (ADJUSTABLE), OUTSIDE AIR TO THE SPACE WILL BE AT THE VENTILATION MINIMUM SETPOINT (VENTMIN VALUE IN VENTILATION SETTINGS

TABLE BELOW).

WHEN SPACE CO2 SENSOR DETECTS CO2 LEVELS ABOVE SETPOINT OF 1,100PPM (ADJUSTABLE), OUTSIDE AIR TO THE SPACE WILL MODULATE UP TO THE VENTILATION MAXIMUM SETPOINT (VENTMAX VALUE IN VENTILATION

ELECTRICAL DEMOLITION REQUIREMENTS

THE BASIS OF THESE DRAWINGS WERE SITE OBSERVATIONS, ORIGINAL BUILDING DRAWINGS AND

VARIOUS OTHER SOURCES. EVERY ATTEMPT HAS BEEN MADE TO DOCUMENT THE ACTUAL

CONDITIONS. HOWEVER, THE CONTRACTOR SHALL CAREFULLY EXAMINE THE CONTRACT

DOCUMENTS AND THOROUGHLY BECOME FAMILIAR WITH THE BUILDING/NPS STANDARDS RELATING TO THE WORK. FAILURE TO DO SO WILL NOT RELIEVE THE CONTRACTOR OF THE OBLIGATIONS OF

THE CONTRACT.

THE ELECTRICAL CONTRACTOR SHALL NOTIFY THE CONTRACTING OFFICER OF ANY MATERIALS OR APPARATUS BELIEVED TO BE INADEQUATE, UNSUITABLE, IN VIOLATION OF LAWS, ORDINANCES, RULES

OR REGULATIONS OF AUTHORITIES HAVING JURISDICTION.

THE ELECTRICAL CONTRACTOR SHALL INCLUDE IN THEIR COST THE REMOVAL OF ALL EXISTING

ELECTRICAL DEVICES, CONDUITS, FIXTURES AND EQUIPMENT. DISCARD ALL EQUIPMENT AS

REQUIRED, UNLESS NOTED OTHERWISE.

EXISTING DEVICES NOT NOTED AS EXISTING (E) OR INDICATED ON PLANS SHALL REMAIN, AS THEY PRESENTLY EXIST. FOR DEMOLISHED DEVICES IN WALLS WHICH ARE TO REMAIN, THE ELECTRICAL CONTRACTOR SHALL INSTALL A BLANK FACE PLATE ON THE BACKBOX. FOR DEMOLISHED DEVICES INSTALLED IN THE FLOOR, THE ELECTRICAL CONTRACTOR SHALL CUT THE FLOOR BOX FLUSH WITH

THE FLOOR AND FILL WITH CONCRETE; COORDINATE WITH THE CONTRACTING OFFICER.

THE DEMOLITION OF SOME DEVICES MAY INTERRUPT POWER TO DEVICES DOWN STREAM. THE

ELECTRICAL CONTRACTOR IS RESPONSIBLE FOR REWORKING THESE CIRCUITS TO MAINTAIN POWER

TO THE DOWN STREAM DEVICES WHICH WILL REMAIN.

ALL UNENERGIZED/DEMOLISHED CIRCUITRY SHALL HAVE THE CONDUCTORS REMOVED FROM THE

CONDUIT AND THE CONDUIT SHALL BE MARKED "EMPTY" WITH INDELIBLE MARKER.

HISTORIC MATERICAL CONSIDERATIONS

WOOD SLAT CEILING IN EXHIBIT HALL AREA IS A HISTORIC FABRIC AND SHALL NOT BE

CUT/DRILLED/PENETRATED UNDER ANY CIRCUMSTANCES WITHOUT SPECIFIC APPROVAL AND COORDINATION WITH THE CONTRACTING OFFICER. EVERY EFFORT HAS BEEN MADE TO ENSURE THAT SPECIFIC LOCATIONS REQUIRING NEW OPENINGS ARE IDENTIFIED SPECIFICALLY. PHASING OF INSTALLATION OF EQUIPMENT SHALL BE COORDINATED WITH RE-INSTALLATION OF THE HISTORIC MATERIALS TO AVOID UNNECESSARY OPENINGS

OR DAMAGE ASSOCIATED WITH THE CONSTRUCTABILITY OF THE SCOPE OF WORK.
