Operation Room Laboratory - OR lab - Department of Energy and Process Engineering - NTNU
Operation Room Laboratory
The operation room facilities (OR Lab) will facilitate new research and innovation on energy efficient indoor environment control technologies and solutions for the operating room of the future.

The OR lab is engaged to develop new solutions for the following challenges:
- High mortality in operating rooms
- Very high energy consumption for indoor environment control in operating rooms
- Very high indoor air quality requirements
Contributors to the OR lab: Sykehusbygg, St. Olavs hospital, Swegon, Lindab, Halton, Glamox, COWI, NTNU Campusservice.
