QIAGEN Inc. is currently expanding its North American headquarters and campus located in Germantown, Maryland. This pharmaceutical manufacturing facility expansion will include manufacturing spaces, offices, and a cafeteria. These spaces will be conditioned with new boilers and chillers that are incorporated into the existing central energy plant.
This project presented unique challenges of meeting LEED EA Minimum Energy Performance prerequisite given the higher air exchange rates and clean manufacturing room type spaces that do not necessarily mesh well with ASHRAE 90.1-2007. We utilized our in depth knowledge of 90.1 requirements and how they apply to spaces of this type to help inform the design team on how to improve the design and operation to increase annual energy cost savings and comply with LEED requirements. We worked closely with the mechanical engineering firm to improve the projected energy cost savings; ultimately exceeding the project goals and expectations for this type of project.
