Attachment C-3 Points.xlsx

This document is a technical specification file for the ODOT Building A HVAC Controls Replacement project in Oregon, detailing an extensive inventory of building automation system (BAS) points and control parameters. The project involves updating HVAC controls across two buildings (ODOT Building A and Building B) to improve energy efficiency and simplify operational control. The specification lists over 800 individual control points (PTs) organized by function, including rooftop supply fans (SF1 and SF2), exhaust fans (EF1 and EF2), variable air volume (VAV) units across multiple zones (101-221), boiler systems with dual units, chilled water systems, and fan coil units (FC1-FC37). The points encompass temperature sensors, differential pressure controls, valve positions, pump run statuses, VFD (variable frequency drive) signals, and schedule/enable controls distributed across multiple building networks and controllers identified by port numbers (ranging from 2618 to 11228). The specification includes control loop PID parameters, setpoint reset functions, and alarm status monitoring across both buildings' HVAC infrastructure.

The document represents a detailed point mapping for a building automation system upgrade that requires coordination of heating, cooling, and ventilation systems across multiple zones and floors. Key system components include two boiler units with associated hot water pumps and isolation valves, a chiller system with multiple compressors and a dedicated chilled water pump with VFD control, numerous VAV boxes with individual zone temperature and damper control, and extensive monitoring of supply/return temperatures, pressure differentials, and equipment run statuses. The specification indicates integration of thermostatic controls, freeze protection monitoring, filter pressure monitoring, and comprehensive status reporting for all major HVAC equipment. This level of detailed point specification suggests a complex retrofit project requiring careful coordination between controls contractors, system integrators, and HVAC equipment suppliers to ensure proper integration of all monitored and controlled parameters across the facility's distributed control network.
