In 1979, extensive planning for the site and building began with final construction completing in 1985. Since the site consists of several acres of wetland habitat and sixty-acre lake, the goal was to create minimal impact upon the site. Upon completion, 97% of the site was preserved as unmodified wetland and wildlife habitat. The façade is oriented to the south-southeast for solar gain, day-lighting and views, allowing scientists to be exposed to natural light from workspaces throughout the building.
The laboratory backs into a hillside, consisting of a cascading three-level atrium with the entry/reception on the top level, dining commons in the middle, and a research library on the lower level with each of the elements opening up to roof terraces.
HGA Architects & Engineers designed the building in a way to address society’s responsible use of natural resources and integration of the site, building and systems. About 50% of the building’s envelope is earth-sheltered and not exposed to the north wind. The primary heating and cooling system was based on geothermal heat exchange and the environment systems, and laboratory exhaust systems to reheat makeup air. The project has been awarded numerous national conservation and innovation awards for its 92% energy independent structure.
The HB Fuller Company Willow Lake Laboratory represents the mid-century efforts of the profession to address responsible building and energy conservation. The building was the result of the energy crisis of 1979 and its founder, former Governor Elmer Anderson, who was a strong advocate of environmental sustainability.
Willow Lake Laboratory is HB Fuller Company’s world headquarters building. Established by AIA Minnesota in 1981, the 25-Year Award recognises exemplary architectural projects that have withstood the test of time.
Jurors for this year’s 25-Year Award were John Cuningham, FAIA, founder of Cuningham Group Architecture; Nathan Johnson, AIA, 2009 Young Architect recipient and founder of 4RM+ULA; and Blaine Brownell, AIA, Assistant Professor at the University of Minnesota College of Design and founder of the design/research firm Transstudio.
