Building Automation System

Maintenance Scheduling.

UBEMSC always  focus to include programs for control that switch pumps and compressors from operating equipment to stand-by on a scheduled basis. Also, programs that provide maintenance schedules for equipment in every building system shall be included, complete with information on what parts and tools are needed to perform each task.

System Design Considerations.

System Design Considerations.

BAS’s require measurements at key points in the building system to monitor part-load operation and adjust system set points to match system capacity to load demands. Controls cannot correct inadequate source equipment, poorly selected components, or mismatched systems. Energy efficiency requires a design that is optimized by realistic prediction of loads, careful system selection, and full control provisions. System ability must include logs of data created by user selectable features. In new buildings and major renovations, the BAS shall have approximately 20 percent spare capacity for future expansion. The system must provide for stand-alone operation of subordinate components. The primary operator workstation must have a graphical user interface. Standalone control panels and terminal unit controllers can have text-based user interface panels which are hand-held or fixed.

Energy Measurement Instrumentation.

BAS shall have the capability to allow building staff to measure energy consumption and monitor performance which is critical to the overall success of the system. Electrical values, such as V, A, kW, KVAR, KVA, PF, kWh, KVARH, Frequency and Percent THD, should be measured. See also Chapter 6: Electrical Engineering, Site Distribution, for separate metering of power consumption.
Energy management measurements shall be totalized and trended in both instantaneous and time-based numbers for chillers, boilers, air-handling units and pumps. Energy monitoring data shall be automatically converted to standard database and spreadsheet format and transmitted to a designated PC.
