Planning a Large-Scale Infrastructure Replacement—Part Two

Bradley Rohloff, Harley Ellis Devereaux
Anthony Lozier, SFA Architects

This presentation is a continuation of the presentation "Planning a Large-Scale Inrastructure Replacement" given at the Labs21 2007 Annual Conference and will provide an overview of the ongoing design of Phases II and III and the current construction of Phase I, part of the complete replacement of the HVAC infrastructure at the EPA AWBERC facility in Cincinnati, Ohio. This ten story, 400,000 square foot laboratory was constructed in the 1970s and has been slated for full replacement of its HVAC system infrastructure.

We will begin the discussion with a summary of planning a multi-phased, large-scale infrastructure project, while the building remains functional. This includes a discussion of solutions to complex mechanical system installations within an existing building. The implementation of equipment planning, to ensure that older equipment can be removed from the facility and new equipment can be installed in its place, will be reviewed. Additionally, we will review energy saving concepts employed in Phase I and designed for future phases to reduce the building's annual energy use by 40 percent.

We will conclude with a discussion of implementation with the construction progress of Phase I. This includes construction phasing, lessons learned, and budgeting, which will all be used in future phases. It is critical that the majority of the facility remain functional during construction. Therefore, employment of the phasing plan and its effect during construction will be discussed.

One of the main drivers of the EPA AWBERC project is reduced energy consumption. Every aspect of the HVAC system concept development, from system types to specific technologies employed, includes strong consideration of energy impacts for long term sustainability.
