Building Interiors

As part of our green building efforts, Catholic University emphasizes sustainability and occupant health and wellness during building renovations. For instance, in 2023 the University completed several interior projects with a focus on sustainable design and furnishings that support healthy indoor air quality.

  • In the Anthropology Suite in O'Boyle Hall, 87% of the furniture met stringent environmentally friendly certification criteria from Greenguard, InterTek Clean Air, or SCS Certified Indoor Advantage, with 6% repurposed from elsewhere. The flooring materials received CRI Green Label Plus and Cradle-to-Cradle Silver level certifications.
  • The Columbus School of Law Lower Level Improvements achieved a 93% certification rate for its furniture selections, emphasizing indoor air quality, while the carpet, certified with CRI Green Label Plus, boasted post-consumer content and low volatile organic compounds.
  • The Pryzbyla Hub featured many eco-conscious carpet and luxury vinyl tile selections, with 86% of the furniture complying with environmental certificates.
  • The Pangborn Lobby renovation continued the university's sustainability commitment with furniture bearing Greenguard and InterTek Clean Air certifications.

LED lighting was also incorporated into each project to ensure energy efficiency.
