Indiana University Health has engaged CMID to optimize their 250 N Shadeland building, which houses their support and accounting staff. The building was built in the 1950s and expanded in the 1970s, with many air handlers manufactured in the 1970s or earlier. The building has five multi-zone air handlers, two variable air volume air handlers, and two constant volume air handlers, and a mix of digital and pneumatic controls. One multi-zone unit and the two constant volume air handlers had been replaced and the controls updated as of Spring 2016. Additionally, one chiller had been replaced in 2013 and another is scheduled for replacement. Two boilers provide heating hot water to the building, one installed in 1966 and one installed in 1993.
CMID completed programming on a new Daikin magnetic-bearing chiller installed winter 2015/2016 into the existing Niagara AX platform. The chilled water pumps for the chilled water plant were also replaced at that time, and those controls as well as the existing Trane chiller, replaced in 2013, were integrated into new chilled water plant programming.
CMID is advising IU Health on modernizing controls within the building, from the older Staefa controllers to the existing AX platform. Along with these controls recommendations, there are many potential mechanical updates to the multizone and VAV air handlers, which CMID is identifying and prioritizing for review by IUH. Additional energy saving projects will be proposed once the mechanical issues arising from the age of the equipment have been resolved.
