Abstract
Interior partition walls for non-residential and high-rise residential construction are an US$8 billion market opportunity in Canada and the United States (Crespell and Poon, 2014). They represent 1.6 billion ft² (150 million m²) of wall area where wood currently has less than 10% market share. To approach this market a new system would be needed to compete against the incumbent system (wood/steel stud plus gypsum). The system would need to have an installed cost before finishing of approximately US$5 per ft² or lower. The system would also need to meet several code requirements for strength, sound transmission and fire resistance (flame spread and burn through). Crespell and Poon further concluded that to be truly transformative, the system would also need to address major trends impacting the building industry including reducing labor, reducing skilled labor, reducing onsite waste, reducing call-backs, and easily recyclable with low environmental impact. A likely market entry point for wood-based interior partition systems may be in taller and larger wood buildings. Work described in this report investigated the fabrication, installation, acoustic and combustion properties of prototype interior partition wall designs. Two types of non-structural prototype interior wall panels designated Type A and Type C were installed between two offices in the FPInnovations Vancouver laboratory. Wood sill plates for mounting the prototype panels were fastened to the concrete floor, sides and top of the opening between the two offices to produce a frame for mounting the test panels. Panels were fastened to the frame using dry wall screws. This same method of installation is envisioned in practice. The installation method makes it easy and fast to both install and remove the wall panels. Acoustic tests showed the difference in ASTC rating measured between a double wall composed of Type A and Type C prototype panels compared with a double wood stud wall with gypsum board faces was approximately 6 ASTC points. A 6 point difference would be clearly noticeable. Although the results of this study are largely qualitative, they suggest that the prototype interior partition panels would have an acoustic advantage compared to stud wall designs. In a related study summarized in this report, the combustion properties of three prototype interior panel constructions, including Types A and C evaluated in this report, indicated that any of the three types of partition constructions could be used in combustible construction in accordance with Division B of the National Building Code of Canada. A second related study, also summarized in this report, estimated an installed cost of US$4.07 per ft² including overhead and profit for unfinished panel partitions comparable to panel construction Type C (gypsum/OSB/wood fibre insulation) as evaluated in this study. Thus, there would appear to be potential installed and finished cost advantages for the wood-based panel partitions compared to steel or wood stud walls with gypsum faces. Other potential advantages of the prototype interior partition panels compared with the most common, currently-used systems (wood/steel stud plus gypsum) include ease and speed of installation, ease and speed of removal, design flexibility, prefabrication including pre-finishing, and easy installation of services. Based on the positive results of these exploratory studies, further development of wood-based interior partition systems including design, fabrication, installation and in-service performance would appear justified. Knowledge of the products and testing methods developed in these studies would be expected to speed further development.

Abstract
The wood products industry wants to expand its market share in non-residential buildings. This is a challenging goal because building codes exhibit a bias against the use of wood products, particularly in the construction of non-residential buildings. The move towards adoption of performance-based building codes offers the promise of eliminating such biases. However, in order to be prepared for the introduction of performance-based codes, architects, engineers and building code officials have pointed out the need for engineering tools to assess the fire performance of buildings. This five-year project was initiated to develop fire-safety design tools for non-residential wood-frame buildings, and to foster development and delivery of educational programs to train students and practitioners in performance-based fire-safety design. In order to achieve these goals an NSERC Industrial Research Chair in Fire Safety Engineering was established at Carleton University in March of 2001. This report summarises the progress towards these goals made by the Chair in his first year of tenure.

Abstract
FPInnovations in collaboration with 475 High Performance Building Supply and the Canadian Wood Council (CWC) engaged in a project to introduce wood fibre insulation products into Canadian construction through a series of high profile demonstration buildings. Dry process wood fibre insulation products have been in use in a variety of structures throughout Europe for more than 25 years. While the market for wood fibre insulation in Europe is both developed and growing, very little is used in Canada and the United States. The goal of this project is to demonstrate the use of wood fibre insulation products in a range of building types with target market areas in the Pacific Region, the Prairie Provinces, and Eastern Canada. Wood fibre insulation was installed into three different buildings in three different climate regions of Canada, a single family residence near Collingwood, ON, a co-op multi-family housing project in Saskatoon, SK, and a laneway house in Gibsons, BC. All three buildings were designed to meet or approach Passive House standards. Two of the buildings were originally designed to use rigid polymer foam insulation. The third building was designed from inception to use wood fibre insulation. In all cases, 475 High Performance Building Supply provided expertise in design and construction using wood fibre insulation. Adapting the building design and construction practices to use wood fibre insulation as exterior insulation was straightforward and easy. Performance monitoring instrumentation was installed in each building. Performance monitoring of each building is to be carried out for at least one year. Wood fibre insulation seems to fit well into Canadian residential construction practices. In these demonstration buildings wood fibre insulation products were readily adapted into wall and roof systems that had originally called for other insulation products. Based on experience in Europe and FPInnovations testing of wood fibre insulation products, wood fibre insulation products would be expected to perform well under Canadian and other North American conditions. The principal challenges to seeing wood fibre insulation products used more widely in Canada and across North America will be the establishment of manufacturing facilities here, along with educating architects, engineers, builders and owners of the advantages these products bring. The objective of this work was to expose wood fibre insulation products through these demonstration buildings to accelerate their acceptance into Canadian and other North American markets. The project team intends to publicize the results of this demonstration building program to architects, engineers, builders and other potential users through selected websites and other publications.
