QualityControl–HydronicFlushingandTreatment

•  Specifications include step-by-step start-up & testing procedure details

•  Conduct a meeting prior to the contractor starting his flushing, review procedures and witness a portion of the process

•  Bypass all coils, control valves and appurtenances, etc. & back-flush fouled

components and clean/replace strainers

•  After treatment, request water analysis to ensure all parameters (pH, TDS, Chlorides, etc.) are within manufacturer’s tolerances.

ON-GOINGCxENERGYINFORMATION•  For School Districts with an ‘Energy Manager’,

energy performance may be at odds with comfort.

•  More districts monitor and track energy consumption and system performance daily, often relying on Energy Information Systems

•  Potential market for CxAs and EMPs for M&V and to support the collection and analysis of this energy data
