KFI provided mechanical and electrical engineering for the new all-electric library, helping create a high-performance building designed to reduce energy use and carbon emissions. Heating and cooling are provided by a water-to-water heat pump system utilizing a Darcy closed-loop aquifer well. Active chilled beams distribute heating and cooling throughout the building and are supplied by a dedicated outdoor air system with energy recovery.
KFI’s electrical design incorporates LED lighting and daylighting controls that take advantage of the library’s open design and natural light. A rooftop solar photovoltaic array further reduces reliance on purchased electricity. Together, these systems support the project’s goal of providing an efficient, sustainable facility while creating a comfortable and inviting environment for library patrons.
The new 10,500 square-foot Hamline Midway Library provides the community with a more accessible and flexible facility while honoring the history of the neighborhood library. Historic stonework from the former building was integrated with daylight and accessibility features to create an inviting environment that reflects the neighborhood’s culture.
The all-electric facility meets the Minnesota B3 sustainable building standard and is designed to use 90% less energy than the Minnesota SB2030 baseline. As the electric grid continues to decarbonize, the building is also positioned to decrease annual carbon emissions over time.
