University of Notre Dame - Joyce Center Green Roof
The Joyce Center’s vegetated roof is the campus’ fifth, and the largest green roof among all U.S. colleges and universities at 85,000-sf. It also represents a key milestone in the University of Notre Dame’s commitment to cut its carbon footprint in half by 2030.
The Joyce Center green roof provides the University both local and campus-wide benefits. In addition to providing lasting and significant bottom line impact, the green roof improves air quality, reduces noise transfer, and demonstrates the University’s commitment to creating a sustainable future.
The green roof assembly includes a protective barrier for the roof membrane. This protective barrier extends the life of the Joyce Center membrane by 200%-300%. As Tony Polotto, Director of Construction and Quality Assurance for the University of Notre notes, ““We’ve put a roof system on this building that should last 40 years.” This increased lifespan minimizes the disruptions and downtimes associated with construction and repairs, eliminates waste that would end up in a landfill, and decreases the roof assembly’s life-cycle cost by as much as 60% compared to a standard single-ply membrane roof. The vegetated barrier provides natural insulation for the Joyce Center, helping keep indoor temperatures lower during warm months and higher during cold months. This enhanced insulation has created an immediate impact on the heating and cooling loads for the building.
