About this file
This HVAC Schedules document is a technical specification sheet prepared by Newcomb & Boyd for the North Carolina School of Science and Mathematics (NCSSM) Morganton Campus Student Wellness and Activities Center (Building G) project. The document details comprehensive HVAC equipment specifications including air handling units, fans, pumps, chillers, boilers, terminal units, and ancillary equipment required for the facility. Key equipment includes two variable volume air handling units (AHU-G-1 and AHU-G-2) serving the wellness center and gym with capacities ranging from 9,000 to 20,000 CFM, two 80-ton air-cooled chillers with minimum 10.1 EER ratings, two 720 MBH condensing hot water boilers, multiple supply terminal units with variable volume and reheat capabilities, ductless split systems for specialized spaces, and various exhaust and relief fans. The specifications establish design conditions with summer outside air at 92.4°F DB and 72.7°F WB and winter conditions at 20°F, along with specific temperature and humidity requirements for different building zones. Equipment is scheduled with detailed performance requirements including CFM ratings, pressure drops, motor horsepower, vibration isolation specifications, and control valve types.
The document incorporates multiple control requirements and performance standards referenced in the North Carolina Energy Conservation Code-2018 and AHRI testing conditions. Vibration isolation requirements are specified throughout, with detailed references to isolation mount types and installation details. Sound attenuation requirements are established with maximum allowable sound power levels for air handling units and fans specified in octave bands from 63 Hz to 8000 Hz. Terminal units include 21 variable volume boxes with reheat coils and one constant volume unit, with heating capacities ranging from 0.8 to 26.4 MBH. Two variable frequency drives are mandated for supply fan operation, and integral motor-operated isolation dampers are required on exhaust equipment. The specifications require dual primary and secondary pump configurations for both chilled and heating water systems, with secondary systems operating at 1200 RPM for energy efficiency. All equipment selections are based on standard industry testing procedures and include references to electrical drawings and detailed installation specifications for vibration isolation and mounting.
