Abstract
La tendance vers la construction verte est en croissance fulgurante depuis les dix dernières années. On estime que le marché de la construction verte représente environ 5 % du marché actuel de la construction. La majorité des bâtiments conçus ou construits dans une perspective environnementale se situent dans les secteurs non-résidentiel ou multifamilial. C’est dans ce contexte que nous nous sommes intéressés à la possibilité de développer et vendre des isolants faits à partir de bois; un matériau généralement reconnu pour ses vertus écologiques. La principale application ciblée dans le rapport est les cavités murales. Ce rapport se présente en cinq (5) principales sections :
Marché : Le marché mondial pour les produits isolants est énorme. Il est estimé à plus de 190 milliards de pi² base R-1. Près de 70 % de ce total est destiné au marché de la construction qui comprend la construction résidentielle (45 %) et non-résidentielle (23 %). La majorité des isolants consommés à l’échelle mondiale sont utilisés en Amérique du Nord et en Europe de l’Ouest. De manière générale, le marché est dominé par les mousses plastiques et la fibre de verre. Le marché pour les isolants autres (alternatifs) oscille entre 2 et 6 % en fonction des marchés dont il est question. Cette proportion est généralement plus élevée dans la réparation et la rénovation que dans la nouvelle construction. Il existe des variations régionales qui sont documentées dans le présent rapport.
Structure industrielle : Les isolants sont des produits dont la valeur unitaire est relativement faible. Il est par conséquent difficile de livrer ces produits sur de grandes distances. La majorité de la production mondiale se fait dans les deux grands marchés mondiaux soit l’Amérique du Nord et l’Europe de l’Ouest. Le tiers du marché (33 %) est dominé par cinq grandes entreprises qui opèrent plusieurs divisions. Elles sont : St-Gobain, Rockwool, Owens Corning, Johns Manville et Knauf. Il faut dire que les produits dominant actuellement le marché nécessitent d’importants investissements en capitaux. Ceci explique, en partie, cette concentration du marché au chapitre de la production.
Politiques et réglementations : Cette section documente les grandes tendances qui risquent d’affecter la demande pour les produits isolants. L’augmentation des coûts de production des mousses pourrait offrir des opportunités pour d’autres produits. Les exigences relatives aux émissions de gaz à effet de serre pourraient jouer en faveur des isolants faits à partir de bois. Les politiques de réutilisation des matières résiduelles présentent des opportunités quant à l’utilisation de ces résidus pour fabriquer des isolants. La hausse des exigences de performance énergétique exigera l’amélioration des produits communément utilisés ainsi que des innovations à partir des matériaux moins fréquemment employés.
Performance environnementale : Cette section montre que les produits isolants à base de bois peuvent contribuer à l’obtention de 8 à 9 % des points pour les systèmes de certification LEED et Green Globes. Il faut toutefois être conscient que l’isolant représente une petite proportion des matériaux entrants dans la construction d’un immeuble (<1 % en valeur). Ceci démontre l’intérêt, du point de vue de la construction verte, à développer des produits qui ont d’autres fonctions que simplement celle d’isoler.
Comportements et exigences d’achat : Des entrevues exploratoires auprès d’architectes et autres utilisateurs d’isolant ont démontré un intérêt pour des produits plus verts. Les principaux facteurs intervenant dans la sélection du matériau isolant sont sa résistance thermique, son coût et la familiarité avec le produit. Les produits isolants conventionnels ne reçoivent que très peu d’intérêt de la part des architectes. L’isolant n’est pas perçu comme étant très innovateur (c’est plus ou moins une commodité) et a peu d’incidence sur le concept (esthétique ou fonctions) du bâtiment. Une des tendances qui semble poindre actuellement à l’horizon est celle des isolants qu’il est possible d’agrafer par l’extérieur du bâtiment. Les autres sections du document présentent le contexte dans lequel le projet s’est exécuté (contexte, objectifs, équipe de projet, etc.) et font état des conclusions à retenir (discussion et conclusions). Les propriétés et caractéristiques générales des différents matériaux isolants sont présentées en annexe. Cette section complémentaire recense des exemples de produits pour chacun des principaux types de matériaux utilisés sur le marché incluant la fibre et la laine de bois. Les informations colligées dans le cadre de ce projet permettent d’établir ces constats généraux :
À court et moyen terme, les principaux marchés pour l’isolant fait à partir de bois sont le marché non-résidentiel et multifamilial.
Le positionnement du produit isolant bois devrait être du côté des produits verts ou respectueux de l’environnement. Il ne s’agit pas d’un matériau dont la performance surpasse les matériaux communément utilisés.
Pour profiter pleinement de ce positionnement stratégique, le(s) produit(s) développé(s) devrai(en)t : o Incorporer d’autres fonctions (pare-air, pare-vapeur, pare-feu, revêtement structural extérieur, parement extérieur, structure, etc.). o Utiliser des matériaux issus de la démolition d’immeubles existants, fibres agricoles et autres intrants avec une faible empreinte écologique. o Être analysés objectivement par l’entremise d’une analyse de cycle de vie. La conclusion du rapport soulève certaines avenues de recherche pour les années à venir. Parmi celles-ci, on note les pistes suivantes :
Meilleure connaissance des types de construction les plus susceptibles d’utiliser des isolants verts faits à partir de bois.
Critères (incluant le prix et spécification de produit) recherchés par les différents utilisateurs.
Identification des marchés industriels (pas liés à la construction) susceptibles d’être réceptifs à des produits à base de bois.
Potentiel d’utilisation des matériaux de différentes sources (récupération, agricole, etc.) dans la fabrication de produits isolants.
Développement des propriétés (ex. : résistance à la compression) et des procédés.

Abstract
This report discusses eco-labeling and the rise in interest of environmental product declarations (EPDs). EPDs are ISO Type III labels conveying non-judgemental life cycle assessment (LCA)-based environmental performance data about products. These documents work in principle like nutrition labels on food packages, transparently disclosing standardized data about the contents and enabling side-by-side comparison between products. EPDs are a user-friendly vehicle for bringing LCA data to the marketplace. In Europe and Asia, EPD development is on the rise, and some jurisdictions are moving towards making EPDs mandatory; this may have trade implications for Canadian exporters. Meanwhile, North America has been slow to follow this trend, although there is movement in the US towards development of standards. It is in the best interests of the wood products industry to accelerate North American activity in EPDs and position itself as a leader in industrial sustainability by developing EPDs early. Over two decades of work in LCA by the wood industry has already indicated that environmental metrics for wood products are generally better than those for competing products. In this report, EPDs are explained in terms of applications, benefits, risks and market drivers. We discuss how EPDs are created and identify global activity in EPD development and creation of national infrastructures. We address trade implications, assess Canada’s readiness, and provide recommendations for moving more quickly to bring the potential benefit of EPDs to the Canadian wood products sector.

Abstract
Forintek, Tembec, Comact and McMaster University have developed the Smart Mill Assistant (SMA), a real-time system that rapidly detects when the process is out of control. The SMA will assist sawmill managers and supervisors with detecting, identifying and correcting process deviations. The SMA relies on the acquisition and analysis of process data in real time. Multivariate statistical analysis, simple data analysis and visualization methods have served as a basis for the development of monitoring and diagnostic models. The SMA monitors the process at two levels. The first model monitors the overall process. It can detect when the process is out of control, and identify the variable or machine centre responsible for a problem, but it does not, however, identify the factors responsible for the problem. At the second level, we have developed an expert system for one machine centre, the bull edger, which is capable of detecting problems, identifying the causes for them, and suggesting solutions to mill users. The SMA has been implemented in a Tembec pilot sawmill. Based on the models in place, we estimate that gains of $5 to $10/Mbf are theoretically achievable. Actual gains will vary with the type of equipment, personnel reaction time and its ability to correct problems. At the time of report preparation, the evaluation of actual gains was not totally completed.

Abstract
This project looks at consumption patterns for structural wood products within the Top 20 residential homebuilding markets in North America. A first objective was to document the use of wood, steel, and concrete materials in structural floors, walls and decking applications. In all these applications, the most important attributes required by homebuilders were outlined and ranked. The project further allows characterizing the performance of wood, steel, and concrete on these demanded attributes. Results show that wood products continue to be under pressure from the growth of concrete slab floors. While the basis for growth in the use of concrete slabs was traditionally found in the U.S. South, this survey points out that western and northern cities may be also susceptible to the growth of concrete slab floors. According to homebuilders, concrete significantly outperforms wood on durability, strength/structural integrity, and acoustic performance. Two of these attributes (durability and strength/structural integrity) are among the Top 3 important attributes in floor applications. The use of concrete in structural walls, either poured or concrete blocks, is well over 65% in Tampa, Orlando, and Miami. Concrete use in walls also reached a market share ranging between 20% and 30% in New-York, Minneapolis, Washington, and Philadelphia, indicating a possible spread of concrete use in walls in some markets which traditionally relied on wood. The market share for wood in walls remains very strong especially in Dallas, Austin, and Houston. Concrete significantly outperforms wood on durability, strength/structural integrity, and acoustic performance. Two of these attributes (durability and strength/structural integrity) are among the Top 3 most important attributes in walls. For wood to remain a competitive alternative in walls and floors, these attributes should be guiding the development of future wood based products and building systems. Wood based sheathing (OSB, Plywood and Fiberboard) retains over 85% of the market in 17 of the 20 metro areas. However, foam and kraftboard sheathing (alone or in combination) have a market share of 10% or more in 6 areas: Detroit, Houston, Austin, Dallas, Phoenix, and Chicago. In Chicago, the market share of foam and kraftboard together even reaches 24%. When comparing the performance of wood based sheathing with foam based sheathing, plywood and OSB are significantly thought superior to foam for strength, structural integrity, resistance to jobsite damage, environmental friendliness, and code acceptance. Foam is said to perform better than OSB or Plywood for both acoustics and energy performance. As a result, acoustics and energy performance in sheathing applications prove to be valuable paths for product development. Composite decking has captured at least 20% market share in 12 of 20 of the metro areas. The highest market shares are found in Denver (71%), Washington (50%), Seattle (45%), and Philadelphia (40%). Clearly, composite decking now offers the greatest competition to wood in decks. This is shown by the satisfaction measures of decking materials which are greater for tropical hardwood and composite/plastic lumber than for wood, treated or not. Composite materials seemingly suit better the most demanded attributes, including durability, appearance, and longevity.

Abstract
Past market studies (Lavoie, 2008; Fell et al., 2006; Robichaud, 2003; Eastin et al., 2001) have shown that wood is increasingly threatened by replacement materials such as concrete, wood plastic composites and steel. It is within this context that this project sought to estimate market shares and explain material preferences of homeowners in decking, floor and wall applications. Issues of environmental performance of materials as well as influence of communication media were also addressed. Fifty (50) respondents from the top 20 metropolitan construction areas were surveyed yielding a total of one thousand respondents. The originality of this project largely lies in the fact that results can be analyzed at small-scale as opposed to the four region approach most construction data employs. A significant proportion of North American homes (40%) have decks. Most of them are built using treated lumber (55%). Wood plastic composites, the key threat to wood products, have yet to capture 10% of the market. Yet, based on homeowners’ preferences for next deck surfacing products, wood plastic composites are in position to increase their market shares to 38%. Some cities, such as Washington, Philadelphia, Las Vegas and Denver, have anticipated market shares equal or above the 50% mark. Consequently, wood plastic products are in a position to gain ground (over treated lumber and other non-treated wood alternatives) in decks. Strength/structural integrity and durability/low maintenance are two attributes on which they perform well. Incidentally, these two attributes are also those that homeowners look for the most in decking products. Wood floors (over basements or crawl spaces) represent the majority of floors (51%) currently built in the US. Current concrete (mainly slabs) market share stands at 37%. Attributes most sought by homeowners are strength/structural integrity, durability/low maintenance as well as lower energy bills. Despite the fact that perceptions of durability and strength remain challenges for wood floors, it appears they will acquire 10% market shares in future floors built in the US. Key assets of wood products include lower energy bills, ability to make repairs, warmth in winter and comfortable to walk/sit on. It is possible that affordability issues will stimulate the expansion of wood products in floors. This may be an indication that there are region/climate specific opportunities for wood products. Yet, it is likely that concrete floors will maintain or increase their shares in most markets of the South region (where they are mostly built) based on homebuilders’ influence on material selection. Market shares for wood products in wall applications suggested that homeowners were generally uninterested by wall material selection. This manifested itself in potential added shares for alternative techniques such as insulated concrete forms and structural insulated panels. One of the key outcomes of this project consists in the data collected on perceptions of environmental merit of building materials. In short: Ø Wood’s environmental assets (green, renewable, recyclable, etc.) continue to be shadowed by concerns of regeneration/scarcity of the material. Ø Steel is seen as being equally recyclable as wood. It is seen as a durable material. Ø Concrete is viewed as the best material to ensure low energy costs. This is an attribute homeowners currently rate very highly. Ø The impact of materials on greenhouse gas emissions is not a salient/tangible concept in the minds of homeowners. It is likely to gain in importance as green building standards and knowledge of environmental impact of product on a lifecycle basis develops. Ø Energy efficiency/costs issues (more than any other environmental issue) are important for homeowners. Following structural issues (durability and strength), homeowners are giving significant consideration to energy efficiency. It is the most important complaint homeowners have about their current house. Unfortunately, wood is supplanted by concrete on the energy issue in floor applications. Respondents were asked to identify the information sources that influence them the most in their material selection decisions. The top five communication media identified are (in order) physical examples, neighbours/friends/relatives, home center staff, TV shows/DIY network and internet/websites. The results suggest complementary promotion and communication strategies should be evaluated by the wood products industry.

Abstract
Industrial markets were investigated due to their relatively high importance for the wood products sectors. In 2009, it was estimated that about a third (33%) of all lumber use went to markets other than construction. The information collected in this project allowed estimating consumption volumes for the five (5) sectors studied: bedframe, engineered flooring substrates, formwork, pallets and crates, and household furniture.
In addition to gaining a better understanding of volumes and products used, the project focused on trying to identify unmet user needs or product issues influencing satisfaction with wood products. This kind of information could result in opportunities to substitute products currently used or develop new markets for wood products currently used. Clear cut opportunities specific to each sectors were difficult to identify. It is apparent that wood product users are yearning for straighter products and products displaying fewer defects like wane, knots, etc. This could point towards potential markets for finger jointed and engineered products. The demands for more products that are more visually appealing is somewhat surprising since these are not typically associated with industrial applications. The information comprised within this report will serve as the basis to explore future business opportunities for wood products in specific business cases.

Abstract
Canadians spend 88% of their time in indoor environments. With such high exposure to buildings it is important to understand what type of environment they are surrounded by. This study took an initial step to create an inventory of materials used in different types of buildings. Not only does this study look at what materials are used in buildings, it also studied how occupants see their surrounds with respect to an inventory of environmental descriptors. Finally, respondents in this study were asked if they would like to see more or less of a series of materials used for each building types. The goal of this study is to provide a baseline for which to set priorities with respect to targeting further visual wood use in buildings. This report contains a literature review on buildings and their users. Building inventory and construction data is contained within this report for homes, offices, hotels, hospitals, schools, libraries, and recreational facilities. It also looks at the annual users and intensity of usage of each type of building. This provides a baseline for which to evaluate the human benefit of using more wood in various environments. Two surveys were executed to collect primary data for this study. A study of the general Canadian population over 25 years old looked at the use of materials in their home environments. There were 545 respondents to this survey. The second survey had the same population parameters but looked at the use and experience in non-residential buildings. There were 646 respondents to the non-residential survey. Highlights and results by building type are below: Homes: There are 32.5 million regular users of home environments. Half of the average Canadian’s waking time is spent in their home. In general, the materials used in the home matched the materials desired in homes and in other types of structures. These priority materials are wood, glass, and plants. The reason that home materials match the desired materials is that 67% of Canadians are homeowners and they can remodel their home environment to their own desires. This is a high priority sector because of the volume of inventory (close to 13 million homes) and the intensity of remodelling and new starts. Offices: Offices have some 4-6 million regular users in Canada. There are 410 million square feet of commercial office space in the country. Wood is used in offices but not intensely. Material use is actually quite spread out. However, respondents would like to see more wood and plants in their office environments to make them more agreeable. Offices are generally perceived to be clean but not particularly warm, healthy, or productive. This is a priority sector as commercial spaces turn over often and are remodelled and new furniture and fixtures are added. In 2007 there were over $5 billion in permits issued for construction and remodelling to office buildings, not including the fixtures and furniture. Hotels: Hotels are a medium to high priority for further wood use. There are only 376 thousand regular users of hotels (workers) but there are 84 million overnight stays per year in the country. When people do stay at hotels they are foregoing their comfortable home environment. Hotels can recreate this with the appropriate use of materials. While there was a moderate amount of wood used in hotels it was clear from the study that more wood, glass, and plants are desired. The top descriptor for hotels was clean, but relaxing and warm were also common. Hotels were not seen as natural, healthy, or productive. Hospitals: Hospitals are a low to medium priority for further wood use. While respondents would like to see more natural materials in hospitals this must be tempered with the intense durability and cleaning demands of a hospital setting. Hospitals are high stress environments. However, respondents disagreed that hospitals felt healthy or natural. The only statement they agreed with was that hospitals are clean. Respondents desire less concrete, metal and plastic and more wood, glass and plants. Durability must be a key consideration for further wood use. This could involve hardening and coatings. Alternatively, wood could be selectively applied to ceilings where durability is not an issue and patients are often forced to stare from their bed. Schools: Schools are a moderate priority for further wood use. Like hotels the need for a positive indoor environment must be tempered with the need for durability. Schools and colleges are heavily used with close to 7 million regular users (teachers, staff, and students). This puts school use on par with office use in Canada. Respondents reported concrete, plastics, and glass were the most commonly seen materials in schools. Of these they wanted to less concrete and plastics and more natural materials. Design for durability is needed to add more natural elements to schools. Libraries: There are approximately 2700 non-school libraries in Canada. Libraries faired well with respect to the match between actual and desired material usage. More natural materials are desired but respondent were moderately happy with library attributes. Recreation facilities: Pools and arenas are heavy users of concrete and metal. There are approximately 2500 ice rinks and 1200 public swimming pools in Canada. Interestingly half of this infrastructure was built in the 1970’s and is therefore due for replacement and renovation. These buildings have had infrastructure money directed at them as part of the 2009 economic stimulus package. While more natural materials are desired these demands of these structures mean that mixed material solutions are the most likely. Strategies for more visual wood use: There is a desire for more wood use in many non-residential buildings. One of the key issues is the heavy use of these buildings makes wood surfaces more susceptible to wear and tear. The key to more visual wood use in non-residential construction is to focus on its strategic application rather than applying what we do in residential construction. Momentum is beginning to build in the structural / visual application of wood. These applications are often in roof systems where wood performs well structurally and is not subject to user wear and tear. Three strategies for further visual wood use are: 1. Up and away – visual wood applied where user wear and tear is reduced, 2. High performance surfaces – hardening and finishing to reduce wear and tear and to aid in cleaning, 3. The mixed material toolbox – apply wood in combination with other materials considered natural or preferred. These are plants, glass and stone.

Abstract
Forintek, Tembec, Comact et l’Université McMaster, ont réalisé le développement du Smart Mill Assistant (SMA). Le SMA est un système fonctionnant en temps réel qui détecte rapidement le procédé hors contrôle. Ce système aidera les gestionnaires des scieries et leur personnel de supervision à détecter, identifier et corriger les déviations du procédé. Le SMA est basé sur l’acquisition et l’analyse de données en temps réel. L’analyse statistique multivariée et des méthodes d’analyse simple et de visualisation de données, ont été utilisées pour la construction des modèles de monitorage et de diagnostic. Le système SMA surveille le procédé à deux niveaux. Dans un premier temps, le procédé a été observé dans son ensemble. Le modèle développé permet de détecter lorsque le procédé est hors contrôle et d’identifier la variable ou le centre de transformation en cause, sans toutefois identifier les causes du problème. Dans un deuxième temps, un système expert a été développé autour d’un centre de transformation, la débiteuse à scies multiples. Les modèles développés pour ce système permettent de détecter le problème, d’en identifier les causes et de fournir des solutions aux usagers. Le SMA a été implanté dans une scierie pilote de Tembec. Les modèles implantés permettent d’estimer théoriquement un gain potentiel de 5 à 10 $/Mpmp. Ces gains varieront selon le type d’équipement en place, le temps de réaction du personnel de la scierie et la capacité à corriger les problèmes. L’évaluation des gains réels n’était pas complétée au moment de la rédaction du rapport.
