Wood Harbinger designed an HVAC system that can kill influenza in 15 minutes or less; this beats the code requirement by 75%, contributing to better patient and provider health outcomes in the clinic.


As demand for healthcare services grows, hospitals are seeking cost effective ways to enable accessible care. With a creative vision, Providence acquired an existing big box retail store and brought on an innovative design team to transform it into a highly efficient medical office building. Wood Harbinger provided mechanical and electrical engineering for the new 24,500 SF clinic, which includes exam rooms, a diagnostic imaging suite, a laboratory suite, and administrative spaces. Through a collaborative effort, the design team prioritized pathogen control, maintained an open and comfortable feeling in the space, and maximized accessibility of the building systems.

Knowing that hospital-acquired infections (HAIs) are an ongoing problem in the healthcare environment, we focused heavily on HVAC strategies that could help mitigate the spread of airborne viruses. Our HVAC solution combined a variable refrigerant flow (VRF) system with an energy recovery ventilator (ERV) and the reuse of pre-conditioned air. Dedicated exhaust fans and room controls enable isolation exam rooms. Together, the elements of this HVAC system can kill influenza in 15 minutes or less; this beats the code requirement by 75%, contributing to better patient and provider health outcomes in the clinic. The system is also still highly efficient, resulting in operation cost savings and a more sustainable medical office building.

We incorporated a utilities mezzanine within the building, with an equipment platform for mechanical and electrical services. The easily accessible space is safer for maintenance and repair technicians, and enables a streamlined distribution layout, further improving energy efficiency.
