Aerzen USA's headquarters creates a statement of possibility for light
manufacturing facilities that are environmentally responsible,
worker-friendly, cost competitive, and architecturally significant. The
project includes a 8,000-square-foot office space and a
34,000-square-foot light manufacturing, shop, and storage areas. In the
nexus that links the shop and the office is a wall-to-wall window that
provides a visual reminder of the dual nature of the business. In the
conference room, straw bale walls were selected for their unparalleled
ability to insulate (R 42), minimal embodied energy, appropriateness for
an organic design, and contribution to the local economy. In the shop,
low-tech earth tubes naturally cool air by passing it underneath the
building, while large fans draw hot air up and let it escape through
operable clerestories. In the office, a ground source heat pump uses six
300-foot deep wells to exchange their temperature with the ground to
provide efficient air conditioning as well as heating.
Key to the building's environmental response is its relationship to the
path of the sun. With a 189 KW solar system soon to be installed, Aerzen
will soon be producing 90% of the energy it uses. These facilities were
completed to LEED Gold Standards and are modeled to use 50% less energy
than a comparable building. The natural surroundings are not ignored,
but instead celebrated through nature trails, as well as native meadows
vegetated swales that account for 100% of infiltrated storm-water
mitigation on site. Special attention not only to the work environment,
but also to the workers, was given through the creation of daylit spaces
to improve worker conditions, and through the inclusion of the entire
company in a 5 day integrated design charrette to involve them in the
