IN PARTICULAR THIS PROJECT USES AN OCCUPANCY SENSOR AT THE SECURITY BUILDING AND An ENERGY RECOVERY UNIT FOR VENTILATION NEEDS AT THE CORE FACILITIES BUILDING. SEE ASHRAE 62.1 VENTILATION COMPLIANCE SCHEDULE. C403.7.4.2 THE PROJECT OCCUPANCY SENSOR AT SECURITY BUILDING WILL AUTOMATICALLY TURN OFF THE SUPPLY AIR FAN WITHIN 30 MINUTES OF THE OCCUPANTS LEAVING THE BUILDING. C403.7.8 THE OCCUPANCY SENSOR FAN AT SECURITY BUILDING WILL COMPLY WITH THE REQUIREMENT OF SHUTOFF DAMPERS AND BE CLASS 1 LEAKAGE OF LESS THAN 4 CFM/SF AT 1.0 INCH WATER GAUGE WHEN TESTED IN ACCORDANCE WITH AMCA 500D. C403.8 THIS PROJECT DOES NOT HAVE ANY FAN SYSTEM MOTOR NAMEPLATES EXCEEDING 5 HP. C403.10 CONSTRUCTION OF HVAC SYSTEM ELEMENTS COMPLY WITH THIS SECTION. DUCTS CONVEYING OUTSIDE AIR WILL BE INSULATED TO R-7, PER TABLE C403.10.1.1 OUTDOOR AIR DUCTS INSIDE A CONDITIONED SPACE CRITERIA <2800 CFM WILL BE USED FOR THIS PROJECT. PER C403.10.1.2 ALL OTHER DUCTS SUPPLY, RETURN, EXHAUST DUCTS WILL BE INSULATED USING A DUCT LOCATION AS INSIDE UNCONDITIONED SPACES, R-6. C403.10.2 THIS PROJECT USES LOW PRESSURE DUCT SYSTEMS OPERATING AT < 2 INCHES WATER GAUGE, CONSTRUCTED PER IMC AND THAT WILL BE LONGITUDINAL AND TRANSVERSE JOINTS SEAMS ANS CONNECTIONS SEALED WITH WELDS, GASKETS, MASTICS OR TAPES IN ACCORDANCE WITH THE MANUFACTURER'S INSTALLATION INSTRUCTIONS AND THE SPECIFICATIONS. C403.10.3 PIPING INSULATION WILL BE APPLIED PER TABLE C403.10.3 PER FLUID OPERATING TEMPERATURES, INSULATION CONDUCTIVITY AND NOMINAL PIPE OR TUBE SIZE. C404 NOTES SEE PLUMBING, C405 NOTES SEE ELECTRICAL. C406.1 ADDITIONAL ENERGY EFFICIENCY CREDIT REQUIREMENTS, THIS PROJECT COMPLIES WITH EXCEPTION 1 BY BEING LOW ENERGY SPACES WITH SUFFICIENT PACKAGES FROM TABLE TO ACHIEVE A MINIMUM OF THREE CREDITS.
