ROCHESTER — The new $64 million Oakland University Human Health Building has become the first LEED Platinum certified building on a university campus in Michigan.
Designed by SmithGroupJJR, the 160,260-square-foot, five-story, terra cotta-clad building, built on the former site of a parking lot and an untended natural wetland, features some of the industry’s most innovative, energy-efficient building systems and advanced sustainable design features.
The project’s primary funding of $40 million came from the State of Michigan legislature’s Capital Outlay Program. Then, to achieve the highest LEED rating — Platinum — while staying on budget, Oakland University, assisted by SmithGroupJJR, successfully pursued a $2.7 million grant from the U.S. Department of Energy, allowing the project to proceed with a full geothermal and renewable energy system.
“The collaboration between Oakland University, SmithGroupJJR and The Christman Co. truly benefitted our ability to design and build the most energy-efficient and sustainable building on any college campus in Michigan,” said Terry Stollsteimer, associate vice president, facilities management.
The facility’s energy systems are designed to save an estimated 35 percent in energy costs annually compared to the LEED prescribed “baseline” building.
A geothermal field, consisting of 340 wells built 320 feet underneath the university’s main parking lot, uses the earth as an energy source for heat pumps that efficiently provide heating and cooling for the building.
A total of 117 vacuum tube solar thermal panels provide “free” heat for the building in the wintertime, the desiccant dehumidification system in the summertime, and domestic water heating all year round. Four, 25,000-gallon underground tanks store any excess solar generated hot water until it’s needed.
A rooftop photovoltaic system, comprised of more than 200 solar panels covering 3,600 square feet, provides 45 kilowatts or 3 percent of the building’s power.
“Environmentally friendly buildings have shown to have positive effects on the quality of their occupants’ health, so it was easy for the university to decide that the new Human Health Building should be highly sustainable,” said Chris Purdy, AIA, LEED AP, SmithGroupJJR principal-in-charge for the project. SmithGroupJJR provided architectural design and development; mechanical, electrical, plumbing, structural and civil engineering; lab planning; interior design; landscape design and LEED certification and documentation.
The building’s environmental friendliness doesn’t end with the innovative, energy-efficient building systems. Outside, a grand porch created by the overhang of the upper floors protects faculty offices from the solar heat gain of a southern exposure. Exterior offices are outfitted with vertical sunshades and fritted glass to reduce glare and cut down on outside heat. Rainwater from the roof is collected and stored in a below-grade cistern, and used for site irrigation.
Inside the building, an elongated floor plan with floor-to-ceiling windows allows for abundant access to natural light and views of outdoor spaces. The interior’s use of recycled, regional and low-VOC materials includes sealed cork floors and bamboo cabinets, and walls are made with insulated cinderblock to reduce energy costs. Daylight and occupant sensors are used throughout the building to reduce energy use by occupants.
Directly south of the building is a towering, 100-year-old Oak tree that was integrated into the site design, rather than cleared. The site’s natural wetland was rehabilitated with native vegetation and invasive species were removed, thereby creating an outdoor lounge and gathering place for students.
