Equipment type: Central AHU and roof exhaust fans
* 0 to 10 score, with 10 being excellent and 0 being poor or not applicable* Review trade contractor's punchlist.[check] PROJECT CLOSEOUT* Confirm equipment and terminals are barcoded.SPECIFICATION REVIEWThe analysis and selection of the optimum HVAC system for a specific project can be determined through energy and life-cycle system analysis software program studies. This assessment should be part of optimizing energy performance when pursuing LEED[TM] project certification and/or other high-performance grant programs.The design of intent of this variable-volume application is to separate the cafeteria space into one HVAC zone with zone a2 being fine kitchen work area and zone #3 an area located off the kitchen where the dishwashing occurs. This month's "Back to Basics" focuses on the building/energy management portion of the system application while this month's "HVACR Designer Tips" focuses on project closeout.* Complete final commissioning report.* Transfer CAD-layered facility management drawings.** Design intent document;* Confirm equipment and distribution complies with standard details.* Post electrical one-line diagram (laminated) in equipment room.* Based on 5,000 sq ft of cafeteria space* Review water balancing report data-to-actual performance (e.g., pressure gauge readings, flow meter readings, etc.).If you have any comments, suggestions, or questions regarding this designer checklist, contact Amanda McKew at amckew@rdkengineers.com This column is meant to provide some basic guidelines for good design. Always consult all necessary codes and resources relevant to each particular project.* Transfer barcoded equipment database.* Review building automation points list checkout.* Transfer recommended operating budget.Barcode designation: 1111111Equipment location: Equipment room 101 and roof* Review air balancing report data-to-actual performance (e.g., static pressure, exhaust and makeup air).* Complete recommissioning manual.* Transfer CAD-layered record drawings.* Confirm Division 16 electrical requirements have been met.* Post AHU-1, EF-1, and EF-2 flow diagrams (laminated) in equipment room and also post within EF unit enclosures.* Transfer barcode scanner.The approach is based in part on the 2004 ASHRAE Handbook--Systems and Equipment, Chapter 1, "System Analysis And Selection Process. in addition, our scoring is based on our own design, construction, commissioning, and building management experience, as well as the use of the "Intelli-Hood Control" system (www.melinkcorp.com) for variable volume kitchen hood exhaust system. Scoring may differ based on project location, current costs, and local engineering experience.* Transfer recommissioning manual.[] TERMINAL EQUIPMENT AND SPACEEquipment designation: AHU-1, EF-1, and EF-2Total HVAC system application score is 246 points out of a possible 320 points, for a rating of 77%.
