Holabird & Root renovated and expanded the Vermeer Science Center. Built in 1978, the Vermeer Science Center needed significant upgrades to mechanical systems, computer network connections, classrooms and laboratory spaces. The new wraparound addition houses biology, chemistry, physics, preengineering, environmental studies, mathematics and computer science disciplines. Advanced student and faculty research labs are grouped together by physical requirements such as the concentration of fume hoods or need for proximity to service areas or research greenhouse. All of the faculty offices are clustered together on the north side of the addition to encourage faculty interaction. The prominent corners of the addition feature common spaces used by all of the departments such as study rooms, computer labs and a multipurpose, 100-seat auditorium. Other spaces include a new greenhouse, museum display areas, and a special collections science library and reading room.

Holabird & Root regards environmental stewardship as an inherent part of design. The architect's team of Leadership in Energy and Environmental Design(TM) (LEED® accredited architects and Certified Indoor Air Quality Professional (CIAQP) engineer worked to establish the Vermeer Science Center as the first LEED-certified facility in Iowa. The project received Silver level of certification through collaboration among all parties involved.

Fifty percent of the Vermeer Science Center's site area has been restored from impervious surfaces to adaptive vegetation, including the conversion of an unused tennis court into a grass area.

A photovoltaic array, which was donated to the College, powers a fountain. The water level of the fountain fluctuates with the intensity of the sun. A concrete cistern near the greenhouse collects rainwater from the existing building roof surfaces that is in turn used to water plants in the greenhouse.

More than 60% of building materials and products are manufactured within 500 miles from the site.

Ninety percent of the regularly occupied spaces permit views to the outdoors. The building is 60% more efficient than the ASHRAE 90.1 base building model. Due to the efficiency of the system, there will be an annual reduction of 2,262,800 lbs. of CO2, 12,200 lbs. of SO2, and 7,112 lbs. of NO2 released into the atmosphere. The annual energy cost savings for the reduction in energy consumption is $152,000.

The design team utilized a double passed air system, which supplies air to offices, lecture halls, and classrooms and then returns to a central air-handling unit. Next the fresh air is mixed with the nonlab space air and ventilates the lab spaces. This method allows the laboratory ventilation air to be used to ventilate the entire building, saving the ventilation air for the offices, lecture halls, and classrooms.

The fume hood exhaust system is manifolded, allowing energy recovery coils in the exhaust air stream to reclaim energy used to precondition the makeup air for the entire building. A payback analysis on the heat recovery system determined a payback of 3.5 years. A specialized control sequence allows for decommissioning of fume hoods and further reduces the minimum requirement per hood during the summer.

A specialized fan coil unit cools the sensible solar load projected into the west labs. This resulted in a reduction in chiller tonnage consumed while allowing natural light to enhance the indoor lab environment.

A controller receives a signal from the space occupancy sensor to ensure ventilation occurs only when the space is occupied. Carbon dioxide monitors located in the return ducting and in the most remote classroom help ensure the building is performing above the minimum ventilation requirements.

The Vermeer Science Center has won an AIA Chicago Sustainable Design Award and has received Special Recognition for Energy-Efficient Laboratory Design.
