60+ Years of Design + Innovation

A Healthy Environment
for Patients and Staff

Peter Lougheed Centre
Calgary, Alberta, Canada

“The design team’s leadership and inspiration was instrumental in making the building a landmark in Calgary. The LEED submission is a testament to the dedication and hard work the team put into the project’s design details.”

Ed Mercier
Director of PLC/RGH Capital Projects, Alberta Health Services

This six-story east wing expansion and renovation of the Peter Lougheed Centre helps meet the healthcare needs of Calgary’s fast-growing population.

The project accommodate several new and improved programs, including a diagnostics imaging core, high-technology operating rooms, intensive care unit, cardiac care unit, hemodialysis unit, mental health clinics, mental health short stay, transplant clinic, clinical lab services and a transplant and renal inpatient unit. The new emergency department can handle 75,000 annual visits.

The Centre served as a sustainable design pilot project for the Calgary Health Region. By identifying sustainable strategies early in the design process, the team achieved its sustainability objectives without sacrificing budget, schedule or program considerations. Sustainable design features include operable windows providing fresh air for staff and patients, plenty of natural light in patient rooms, healthy materials and highly efficient mechanical systems.

Infection control is a major challenge for hospitals. The design provides rubber flooring and other easily-cleaned surfaces, mold-resistant drywall, separate hand washing sinks for staff and visitors in patient rooms, and in-room bedpan cleaners. Safety zones allow specific areas to be isolated without impacting operating costs. 

HOK designed the Peter Lougheed Centre in collaboration with Marshall Tittemore Architects of Calgary.
