College Hall, the first building constructed on the University of Pennsylvania’s West Philadelphia campus in 1871, recently earned LEED Gold certification following the completion of a major renovation and restoration.

Listed on the National Register of Historic Places, College Hall has a special relevance at Penn, and its renovation required a unique approach that honored its historic and symbolic importance while also furthering Penn’s Climate & Sustainability Action Plan goals. Those goals include maintaining a Silver or higher certification standard for all major renovation projects. 

Awarded by the U.S. Green Building Council, LEED stands for Leadership in Energy and Environmental Design and provides an internationally accepted standard for sustainable building. Certifications are based on scorecard results that rate projects in areas including energy efficiency, materials management, and indoor environmental quality.

The renovation and restoration project was completed in 2025 and earned high marks for sustainability through a combination of energy‑saving systems, waste reduction, and healthy interior design. 

All building appliances and equipment meet ENERGY STAR standards, and lighting power use was cut by more than half through efforts such as installing advanced daylighting controls and occupancy sensors. Renewable Energy Credits from Penn’s Power Purchase Agreement that were administered by Facilities & Real Estate Services also played a key role in achieving high LEED scores in the energy and atmosphere category.

The project also managed to reduce materials being sent to landfill and incineration. During construction, 80% of debris was recycled, or 1,200 tons—equivalent to the weight of over 200 elephants.

Inside the building, teams selected low‑emitting, certified sustainable materials, from its choices of insulation, flooring, and paints to its selection of PFAS‑free furniture.  The work ensures that the building meets LEED’s indoor air quality requirements to ensure a healthy, well‑ventilated environment for occupants.

In addition to earning LEED Gold certification, the AIA (American Institute of Architects) Philadelphia Chapter awarded College Hall’s renovation and restoration its 2025 Honor Award for historic preservation and adaptive reuse. The awards recognize excellence in design in the Philadelphia area while advancing knowledge and promoting the value of architecture. 

The project also earned a University City Historical Society Outstanding Preservation Award and a General Building Contractors Association Excellence In Craftsmanship Award, both in 2025.

Together, these awards and distinctions highlight Penn’s ongoing commitment to being an urban campus that balances its hundreds-of-years-old history with its commitment to creating a more sustainable future.
