Gunnison County Libraries was looking to replace their existing library in Gunnison, Colorado, with a new sustainable building providing flexible and functional community space. The 15,000 square-foot public facility also needed to stand up to the harsh and variable weather conditions experienced in Gunnison. Winter ambient temperatures in the Gunnison valley range from negative 30 to negative 40 degrees, which sometimes comes with heavy snow, so careful design of the roof systems was critical to handle snow and ice.
Anderson Hallas Architects created the new library design, along with a team of engineers, sustainability consultants, and landscape designers. 360 Engineering provided mechanical and plumbing engineering services, including helping achieve sustainability goals for the project. The energy-efficient mechanical system combined geothermal ground source heat pumps and a variable air volume dedicated outside air system (VAV DOAS) with new DDC controls. The plumbing design and fixtures for the building included restrooms and a warming kitchen for events and community gatherings.
