Implementation and Operation of a Large-Scale Infrastructure Replacement Project Part III
Bradley Rohloff, Harley Ellis Devereaux
Anthony Lozier, SFA Architects
This presentation is a continuation of the presentation "Planning a Large-Scale Infrastructure Replacement Project Part Two," given at the Labs21 2008 Annual Conference. It will provide an overview of the ongoing design and construction of phases III and IV and the current operation of phases I and II. Phases I through IV are part of a five-phase replacement of the HVAC infrastructure at the EPA Andrew W. Breidenbach Environmental Research Center facility in Cincinnati, Ohio. This 10-story, 400,000-square-foot laboratory was constructed in the 1970s and has been slated for full replacement of its HVAC system infrastructure.
The presentation will look back at the operation of the completed phases I and II, as well as looking ahead at the design challenges for phases III through V. We will discuss operation of the new HVAC system installed in phases I and II, its operational effect on the building's occupants, and improved air quality. Issues that were encountered with installation of HVAC equipment while the building was occupied will be addressed. Collateral projects, which developed due to the infrastructure replacement project, will be part of the presentation. One such project is renovation of the process water system by incorporating energy recovery to preheat air for the mechanical space ventilation.
The speakers will conclude with lessons learned in the first two phases and how they simplified, improved, and challenged the design in subsequent phases.
