Case Study: New York Marriott Marquis BAS & Commissioning Bill Michell, RPA, FMA, CEOE Director of Engineering
Retro-Commissioning ( 05-06) NYSERDA co-funded study Re-Commissioning of all major mechanical, AHU & VAV systems Re-Commissioning and re-engineering of Steam systems Electricity reduction of 3% and Steam reduction of 15% Lighting Retrofit ( 06 ROI Project) BOH Lighting conversion to T-8 lamps & electronic ballasts/led Exit signs Escalator lamps converted to Cold Cathode lamps 2 year ROI; 793,300 KWH annual reduction Lighting Retrofit ( 07 ROI Project) Replacement of Atrium rail guest corridor lighting with T-8 fixtures 2 year ROI; 625,464 KWH
Building Automation System ( 08 ROI Project) - Installation of Tridium BAS - Convergence Johnson Controls 9100 BAS & original Honeywell BAS - Installation of VFD s - Integration of Chiller Plant, Hot Water System & Lighting Controls - Chiller Plant Optimization - 2.5 year ROI, annual reduction of 2,887,337 KWH
BAS Commissioning Features - Graphics; Easy operator interface - System operations easily verified - Open protocol; convergence & integration of controls - Trending - Scheduling Tools - Allows for ongoing Continuous Commissioning
