A growing interest in using renewable and sustainable resources as building materials has stimulated design professionals to make use of the long-established structural performance and aesthetic beauty of wood, and push the height limits of wood building construction. At 6-stories high (29.5 m), the Wood Innovation and Design Centre (WIDC) is one of the tallest contemporary wood buildings in North America. With a complex layout including a lecture hall, laboratories, classes, and faculty offices for the University of Northern British Columbia in the lower storeys, and offices in the upper storeys, the WIDC building design includes innovative acoustical solutions to impede sound transmission between adjacent rooms and accommodate the mixed occupancy of the building. Sound transmission tests were carried out to determine the airborne sound insulation performance of selected wall assemblies and impact sound insulation performance of selected floor assemblies. This paper provides an overview of the WIDC building, describes the tested assemblies and the sound transmission test methods, and summarizes the test results.
