New College of Business - LEED Plantinum
The University of Illinois’ new College of Business (Business Instructional Facility – BIF) was among the first certified LEED Platinum facilities at a public university in the U.S. The facility’s high-performance building design reduces energy consumption by 48% compared to ASHRAE 90.1-2004, saving the University more than $300,000 per year in utility costs. The building exceeded the University’s project goal, and now campus standard of LEED Gold, and became the first LEED Platinum building on campus.
Completed in May 2008, the 152,000-SF new facility accommodates 8 high-tech classrooms, career development and academic counseling centers, student program offices, a commons area with café, a recruitment suite with executive meeting rooms, dining room and catering kitchen, 20 interviewing rooms, a 300-seat auditorium, a laboratory that simulates real-time market trading, and space for students to meet and study. Designed by world-renowned architect, Cesar Pelli, the U-shaped structure offers a bright, airy commons area and a spacious, south-facing courtyard. The “heart” of the building is an expansive atrium area that provides space for students to study and interact with each other, as well as host alumni and student events and corporate receptions.
To achieve the University’s sustainability goal, extensive collaboration among the design team occurred early in Concept Planning Phase, resulting in vast computer modeling and life-cycle cost analysis of the building’s orientation, layout, building envelope, and infrastructure systems to optimize the building’s performance. Low maintenance and low operating costs, as well as flexibility and maintainability, were considered in all designs. Designs included:
- 4,000 SF of roof-top photovoltaic panels to convert solar energy into clean and renewable electricity, producing approximately 8% of the building’s total electricity demand.
- A green roof that reduces rainwater run-off into the drainage system.
- Low-energy-use building design reduces power consumption and cooling power from the campus chiller. Zero use of CFC refrigerants reduces ozone depletion.
- Displacement ventilation (DV) system which moves warm and cool air through the building more efficiently than a traditional forced-air system and improves air quality. With increased ventilation effectiveness, the DV System provides incredible energy efficiency.
- Photo sensors on lights to reduce energy consumption as outside light enters a room.
- Motion sensors turn lights off in unoccupied rooms reducing power consumption.
- Low-volume shower heads, toilets, and faucets reduce water consumption.
- Carbon dioxide monitoring to help sustain long-term occupant comfort and well-being while saving energy.
The building’s tight urban site at the heart of the campus made site utility connections and construction challenging. It also limited applications for wind turbines and geothermal bore fields, which were evaluated, due to height restrictions and land access. BIM was used by all members of the project team.
