The busiest library in Minnesota was dark, dated, unwelcoming, and inefficient. A much-needed renovation and second floor expansion completely transform the 1990s building. The design uses the addition of daylit open spaces and views to the outside to accomplish the transformation. Open sight lines, efficient space layouts and technology, and select use of color provide clear wayfinding, accessibility, and self-servicing. The project is LEED Gold certified. A key sustainable strategy entailed reinvesting in the existing site and reusing 75% of the existing structure. The designers also selected regionally-produced and recycled materials. High efficiency systems save water and energy.
