“Knowing that this facility will be around for many, many years to come, we pushed ourselves to do more in terms of sustainability.”
Located on a 6.5-acre, two-block tract, the four-story headquarters shows the possibilities that can come with redeveloping an urban brownfield site. The design celebrates the natural beauty and resources of the Iowa landscape while incorporating basic sustainability principles and promoting employee wellness.
Sustainable strategies are projected to save more than 30 percent in energy costs and reduce Wellmark’s overall water use by 58 percent. Combined with low‐flow water fixtures, a 60,000-gallon cistern system helps save 1.5 million gallons of potable water each year. Among the largest graywater systems in the US, it reclaims rainwater from roof drains, ground water from a subsoil drainage system and condensation from mechanical equipment before sending it to toilets and urinals.
Other green features include an under-floor air distribution system, site habitat protection and a construction strategy that diverted more than 2.5 million pounds of waste away from the landfill.
A fitness center/gym, a cafeteria providing health-conscious choices, ergonomic workstations and natural light help keep Wellmark’s people healthy.
The project supports the revitalization of downtown Des Moines through increased pedestrian activity.
