Provide services and manpower necessary for commissioning of the system in coordination with the HVAC Contractor, Balancing Contractor and Owner's representative. F. All work performed under this section of the specifications will comply with all governing codes, laws and governing bodies. If the drawings and/or specifications are in conflict with governing codes, the Contractor, with guidance from the engineer, shall submit a proposal with appropriate modifications to the project to meet code restrictions. If this specification and associated drawings exceed governing code requirements, the specification will govern. The Contractor shall obtain and pay for all necessary construction permits and licenses. G. The AMBCx provider shall supply equipment, software, installation labor, programming, functional testing, training, and documentation capable of meeting the AMBCx requirements for the Project as specified in this Section. If additional hardware is required, the AMBCx provider shall work with the EMCS contractor and/or other subcontractors to make sure this hardware is installed. H. The AMBCx provider shall host the AMBCx software with off-site servers that shall require no maintenance or management by the building personnel. The AMBCx provider shall be responsible for firmware maintenance, FDD database maintenance and upgrades, and collected EMCS data maintenance and integrity. Software solutions that reside on local site computers with custom locally created one of a kind diagnostic fault detection and analysis algorithms unique to the local supplier will not be acceptable as the AMBCx software must always be running the latest up to date version of both core software and diagnostic fault and analysis algorithms I. The AMBCx provider shall provide a web-based portal to the AMBCx service that shall be able to be accessed by any Internet accessible device with a web browser. The AMBCx website shall maintain a 99 percent uptime. J. Remote access to the EMCS for data collection by the AMBCx system shall be afforded by VPN or other approved firewall ports, with data exchange to the AMBCx system only possible in one direction (outbound to the AMBCx service), and without any means of writing commands, or programming changes back to the EMCS. K. The AMBCx system provided shall be able to satisfy fault detection and diagnostics (FDD) and analysis of the following major mechanical and energy systems in the facility, including, but not limited to, the following: 1. Boiler and other related heating plants. 2. Chilled water plants. 3. Building radiation and slab cooling/heating. 4.

The AMBCx system shall be able to analyze a combination of hard-wired (analog and digital I/O) and virtual points (setpoints, calculated variables) in a system using real-time and historical time-series data to the following (the actual set of analysis capabilities for a particular building shall be dependent on the EMCS data available from that building): 1. Minimum Required Capabilities: a. Determine the stability of control devices (valves/actuators/speed drives) b. Determine the degree of error above reasonable thresholds. c. Compare sensor readings to setpoint and flag out-of-range errors from faulty sensors. d. Compare outputs (controllers) setpoints to actual conditions to find failed devices. e. Calculate and report on energy consumption for systems under EMCS control. f. Ensure economizer systems are working to provide optimal free cooling opportunities. g. Diagnose flow measurement systems to ensure readings are in range of expectations. h. Categorize faults according to various priorities (energy, comfort, and system maintenance impact). i. Identify simultaneous heating and cooling in a system and sub system (precool/reheat). j. Ensure ventilation rates are adequate (testing minimum outdoor air volume settings). k.

The avoidable energy cost for the period selected c. Period trend summary of energy, comfort, and maintenance faults d. The top five issues found during the period for each category of energy, maintenance, and comfort along with a list of recommended actions to correct these issues. e. Graphs of the trends of the avoidable energy costs, maintenance issues, and comfort issues discovered during the period as benchmark to measure operational efficiency from period to period. f. New fault issues discovered since the last report. g.
