Hellems Arts and Sciences Building

Completed in 1921, Hellems Arts and Sciences Building stands as one of the defining structures of the CU Boulder campus. It was the first building constructed in architect Charles Klauder’s signature Tuscan vernacular style, an architectural vision that would come to shape the university’s distinctive appearance for generations. Originally known as the Liberal Arts Building or Arts Building, it was later named in honor of Fred Hellems, a professor and dean in the College of Liberal Arts. 

For more than a century, Hellems has been a cornerstone of the student academic experience. Located within the historic Norlin Quadrangle, the building has hosted countless classes and academic programs, becoming a familiar destination for students across disciplines. The adjacent Mary Rippon Outdoor Theatre, home of the Colorado Shakespeare Festival, further strengthened Hellems’ role as a center for learning, creativity and cultural engagement. 

Following a major renovation completed in 2026, Hellems Arts and Sciences Building entered a new chapter while preserving its historic character. The project modernized classrooms, improved accessibility, enhanced sustainability and created collaborative spaces designed around student success. The recent renovation also transformed Hellems Arts and Sciences Building into one of the university’s most sustainable historic buildings. Despite the addition of air conditioning, the building’s energy use intensity decreased by nearly 68% through a combination of upgraded HVAC systems, LED lighting, enhanced insulation and high-performance triple-pane windows. The project also prioritized resource conservation, incorporating low-flow plumbing fixtures, improved ventilation and daylight-optimized spaces that support occupant well-being while reducing energy demand.

Sustainability goals extended beyond building systems to the preservation of historic materials. More than 80% of the original clay roof tiles were reused, while existing terrazzo and hardwood flooring were carefully refurbished rather than replaced. By combining historic preservation with modern efficiency standards, the renovation ensures that Hellems Arts and Sciences Building can continue serving students and faculty for generations while significantly reducing its environmental footprint.
