Res. Amending the 2013 Budget to Include Expenditures for BAS Improvements at Comm. Center February 11, 2013 Page 2 Public Works has met with a number of mechanical engineering firms and mechanical contractors the past several years regarding the HVAC deficiencies at the Community Center. Every one of these firms and contractors has made mention of the outdated building automation system (BAS) that was installed at initial construction, and recommend upgrading the system. The BAS is the "brains" of the HVAC system that monitors, adjusts, and controls the various HVAC components to provide a comfortable indoor air environment. The BAS is also the interface for Public Works staff (and maintenance contractors) to monitor, adjust, and troubleshoot various HVAC related issues. The current BAS is a Barber Coleman Network 8000 controls system that is obsolete, and no parts or components are available any longer for this system. Public Works evaluated various controls systems for replacing the Barber Coleman system and recommend a Trane Tracer SC controller. This system is a non-proprietary, open protocol, operating platform that will allow the various manufacturer controls to be operated by the system and allow for future expandability with competitive bidding. This will be particularly useful when likely future improvements are made to address humidity issues and other recommendations from the current retrocommissioning study. The only other BAS controller owned by the City is a Trane Tracker for the City Hall building, which can be interfaced with the Tracer SC controller and accessed via the network in the future.
