The Warren E. Burger Federal Courthouse is located in downtown St. Paul. The building was originally constructed in 1966 and underwent a renovation in 2004. The 450,000 square foot building is owned and operated by the General Services Administration (GSA) and is home to 17 courtrooms as well as various office spaces and branches of the government. KFI Engineers provided recommissioning and energy study services for this federal building. The primary goal of the project was to perform a comprehensive energy and water evaluation in order to lower building energy consumption. As part of this process, testing was performed on all of the equipment for functionality and accuracy of the energy management system. A detailed recommissioning plan was conceived using ASHRAE commissioning guidelines to include the following systems: HVAC, lighting, plumbing, and building envelope.
KFI’s technicians pride themselves on being able to find energy savings in any building. This project provided an additional challenge. The building is already a LEED Silver certified building and was previously awarded the regional Outstand Building of the Year (TOBY) award. Compared to other buildings of similar size and use, KFI found the building to already be running at a highly efficient level. Throughout the course of KFI’s investigations, our experienced technicians and engineers were able to uncover deficiencies and annual energy savings that equated to an estimated 10% in total energy and domestic hot water costs.
This courthouse building, which houses District, Appeals, Magistrate, and Bankruptcy Courts, as well as the US Marshals Service, Veterans Administration and US Attorney’s offices is rarely unoccupied during normal hours. KFI was required to perform recommissioning services with minimal to no disturbance to the occupants. The building is open between 7:30am and 6:00pm, coming in before or after-hours required significant coordination between multiple parties, for access and security reasons. Careful coordination was conducted throughout the project to ensure that the spaces being tested were unoccupied and the maintenance staff was available to escort KFI employees. KFI was able to access all necessary areas for testing, with no disruption to the building occupants. This project finished on schedule with great results.
