Jenkins and Nanovic Halls are a new pair of conjoined buildings on a key gateway site at the entrance of the University of Notre Dame’s campus built to house an integrated ensemble for the Social Sciences and the newly inaugurated Donald R. Keough School of Global Affairs. Programmed for two distinct program groups, Jenkins and Nanovic Halls were designed to maintain the separate identities of the Social Science and International programs while locating them within a singular structure that would promote the interdisciplinary interchange between faculty and students, functioning as an intellectual hub for the campus by providing a 24 hour facility for learning, research and study.
The entry sequence into the building is accomodating from all directions on campus with entrances located on the west, north and east. The interior Forum in the south/Nanovic wing addresses the needs of a building that is to serve the entire University community, resident academic departments and institute programs, as well as providing a gathering space for the assembly of diverse groups of visitors from around the world. Major shared building functions are organized around the Forum in an effort to promote student and faculty interaction on a daily basis.
The University’s ecclesiastical roots form the basis for the stipulated Collegiate Gothic style of architecture on campus. Great care was taken with the challenge of reconciling the notable qualities of the Collegiate Gothic style with contemporary circumstances such as modern building floor to floor heights, massing and cavity wall construction.
Sustainable Design Intent and Innovation
The University of Notre Dame is committed to the principles of sustainability and approaches this effort with respect for the human condition, respect for conservation of natural resources and economic viability. Jenkins and Nanovic Halls were approached with an understanding of sound design principles and with considerations made toward sustainable design practices to encompass both the philosophical and technical aspects of the architecture.
As an academic building, located on a university campus developed according to a specific and considered set of architectural and planning principles, Jenkins and Nanovic Halls were conceived to be both physically and aesthetically robust, with the understanding that university buildings should provide for a long, useful life that might include reassignment of use and subsequent additions. To this end, the building reflects a responsible use of resources and is built from durable, natural materials to ensure the building’s longevity. It also is clearly organized with a modular and rational subdivision of the internal spaces and employs a structural clear span over a typical double loaded corridor ‘bar’ which will allow for future reconfiguration of the internal organization should the building’s needs dictate. The above is also reflective of Notre Dame’s Seven Tenets for Campus Planning of which includes ‘Stewardship of the Built Environment and Architectural Forms, Styles and Materials.
It is anticipated that Jenkins and Nanovic Halls will receive a LEED Silver rating. With regard to LEED, the building’s design was based on providing architectural legibility and flexibility, longevity with regard to the building’s lifespan through the selection of durable and sustainable materials, user comfort and energy efficiency through systems design and awareness of the site, climate and environmental circumstances, and employment of sound construction site management practices. The site, set within the Notre Dame University campus environment, benefits from density and an in place network of public and alternative transportation. The stipulated Collegiate Gothic expression resulted in a building with a favorable window to wall ratio which assisted in achieving the minimum requirements for optimum energy performance. Materials were specified for sustainable sourcing and low environmental impact resulting in both recycled content and regional material percentages of over 20%, and low emitting materials were utilized throughout the building whenever possible. Exemplary performance was achieved for construction waste management.
As part of the Jenkins and Nanovic Halls LEED Silver objective, the following energy credits were pursued: Minimum/Optimum Energy Performance, Fundamental/Enhanced Commissioning and Measurement and Verification. Minimum/Optimize Energy Performance (EAp2c1) achieved a 19.48% energy cost savings compared to the ASHRAE 90.1-2007 baseline.
Credits for Indoor Environmental Quality and occupant comfort were also pursued including Increased Ventilation (IEQ2C), Controllability of System (Lighting) an Controllability of Systems (Thermal Comfort). The building’s systems designs were able to increase outdoor air ventilation to all occupied spaces by at least 30% above the minimum rates required by ASHRAE 62.1-2007.
Notre Dame receives a walk score of 54, which is considered to be ‘somewhat’ walkable. Services proximate to the Jenkins and Nanovic Halls site are main campus functions such as University Administration, Academic Buildings, Library, Dormitories, Places of Worship, Police and Fire Department and Student Life. Within ½ mile of the building’s site is the Eddy Street Commons which functions as a “main street” for the greater University and local residential community and provides services such as banks, convenience stores, restaurants, beauty salons and specialty shops.
Shuttle buses are provided by the University from remote parking on campus to central locations including the main administration building, the main library, and the conference center.
South Bend public transportation provides multiple bus routes between South Bend and the Notre Dame Campus.
In addition to public transportation, the Notre Dame Office of Sustainability has instituted a bike share program to facilitate non-vehicular means of transportation on the campus.
Dedicated parking for staff and visitors is not provided for Jenkins and Nanovic Halls as is the University policy. There are numerous parking lots with a ½ mile radius of the site that serve the building. As part of the building’s LEED certification, 17 preferred spots for Low Emitting Vehicles dedicated to Jenkins and Nanovic Halls have been provided.
As part of the Jenkins and Nanovic Halls LEED Silver objective, Water Use Reduction credit (WEp1c1) was pursued and achieved water reduction of 39% compared to the LEED baseline. Water usage calculations compared to the water use baseline are as follows:
i. 1.28 GPF Water Closets
ii. 0.125 GPF Urinals
iii. 0.1 GPC Lavatory Faucet
iv. 1.5 GPM Kitchen Sink
v. 1.5 GPM Shower
Whenever possible, low emitting and sustainable materials were selected for the Jenkins and Nanovic Halls project. Typical VOC contributors such as carpet and paint were specified with low VOC and sustainability certified products. In addition, terrazzo was specified with recycled aggregate and low VOC resin system. All grouts and sealants were also specified with low VOC versions. An Indoor Air Quality Management Plan was followed during construction.
Pre and Post-Consumer recycled content was tracked for the project and documented at an exemplary performance value of recycled content greater than 30% of the total material cost. Materials contributing to this percentage are structural and reinforcing steel, metal roofing, fasteners and flashings, wood stile and rail doors and interior gypsum products.
Recycling has been made very accessible and visible in the common hallways with recycling stations located throughout the building. Dedicated recycling compactors have also been installed in the building.
