Abstract
1re partie Empreinte environnementale du CLT – résultats préliminaires Dans la présente partie, nous déterminons expérimentalement certaines caractéristiques environnementales quantifiées du CLT en tant que matériau de construction, sans toutefois effectuer une analyse du cycle de vie (ACV) exhaustive. Puisqu’il n’existe aucune documentation comparative sur le CLT, nous utiliserons plusieurs approches pour estimer son empreinte environnementale et pour le comparer au béton. À l’aide des données d’ACV existantes du bois lamellé-collé canadien en tant que valeurs de remplacement, nous examinerons l’empreinte du matériau en soi comparé aux matériaux du béton armé ainsi que des matériaux utilisés dans les bâtiments de moyenne hauteur comparativement au béton. Nous ajusterons ensuite les données de l’ACV du bois lamellé-collé pour qu’elles se rapprochent de celles d’une section de plancher de CLT aux fins de comparaison à une section de plancher en béton équivalente sur le plan fonctionnel. Dans chacun des cas, nous estimons que le CLT surpassera considérablement le béton dans chaque mesure environnementale abordée selon l’ACV. 2e partie Effets potentiels sur la qualité de l’air intérieur de l’utilisation du CLT dans les bâtiments – résultats préliminaires Cinq produits de bois lamellé-croisé de différentes épaisseurs et lignes de collage ont été testés aux fins d’analyse de leurs composés organiques volatils (COV) comprenant les émissions de formaldéhyde et d’acétaldéhyde afin d’aider les ingénieurs et les constructeurs à mieux choisir les matériaux de construction ayant le moins d’incidence sur la qualité de l’air intérieur. Les émissions ont été évaluées selon la norme ASTM D 5116 et ont été recueillies après que les échantillons aient été exposés dans la chambre d’essais pendant 24 heures. Aucune corrélation n’a pu être établie entre l’épaisseur du bois lamellé-croisé, les lignes de collage ou la quantité de COV individuels (COVi) émis, comprenant le formaldéhyde et l’acétaldéhyde, ou les COV totaux (COVt). Les cinq produits de CLT ont démontré de très faibles taux d’émissions de COVi et de COVt. La plupart des COV détectés provenaient de composés de terpène de bois résineux utilisés dans la fabrication de bois de construction laminé. Ainsi, lorsque le CLT est employé dans la construction d’un bâtiment, l’effet des COV sur la qualité de l’air intérieur est mineur, voire inexistant. Lorsqu’on évalue les effets du produit sur la qualité de l’air intérieur, on peut facilement conclure qu’il serait négligeable, sinon nul. Les résultats relatifs aux COVt et aux émissions de formaldéhyde des cinq produits de bois lamellé-croisé après une exposition de 24 heures étaient généralement inférieurs à ceux indiqués dans les systèmes européens de marquage des émissions. En outre, le niveau européen E1 pour les émissions de formaldéhyde des produits de bois, qui est établi à 0,1 partie par million (ppm) ou à 100 parties par milliard (ppb), est de 6 à 20 fois supérieur aux niveaux mesurés pour les produits de bois lamellé-croisé. D’ici juillet 2012, l’application de la phase 2 des normes du CARB (organisme de réglementation de l’État de Californie) relative à tous les produits composites sera complétée et les limitations d’émissions de formaldéhyde seront établies à des valeurs variant entre 0,13 ppm (130 ppb) pour les panneaux de MDF (panneaux de fibres de densité moyenne) minces et 0,05 ppm (50 ppb) pour le contreplaqué de feuillus avec noyau de composite (HWPW-CC). En comparant ces limitations à celles des produits de bois lamellé-croisé, on peut conclure que ces produits respectent amplement les limitations les plus rigoureuses du CARB, qui sont de 50 ppb.

Abstract
This study presents a life cycle assessment of two prototype biocomposite formulations manufactured at NRC-IMI in Boucherville, Quebec under a collaborative project between National Research Council of Canada-Industrial Materials Institute (NRC-IMI) and the Composites Department of FPInnovations on the “Development of cellulosic fibres/thermoplastic biocomposites”:
Formulation 1 – uses wood fibre with two biopolymers: polylactic acid (PLA) and thermoplastic starch (TPS). PLA is imported from Nebraska, US and TPS is produced at NRC-IMI using a locally available biopolymer source.
Formulation 2 - uses wood fibre and PLA. The goals set to assess the cradle-to-gate environmental performance of the two formulations are:
Develop life cycle inventory for Formulation 1
Develop life cycle inventory for Formulation 2
Perform contribution analysis to identify significant inputs within the two formulations
Compare and contrast environmental performances of the two formulations
Compare and contrast environmental performance of the two biocomposite formulations with alternative materials such as nylon and polypropylene.

Abstract
This study presents a cradle-to-gate life cycle assessment (LCA) of hardwood lumber produced in eastern Canada. LCA is a comprehensive analytical examination of the flows to and from nature related to a product or a process. LCA is typically performed following international protocols and is considered by many to be the best mechanism for quantifying the true environmental footprint of a product. An LCA can address some or all of the stages in the life of a product. This LCA addresses environmental impacts up to the mill “gate” for hardwood lumber; such a cradle-to-gate assessment is typical for products that are usually destined to be components in any number of secondary products. For those secondary products, a full cradle-to-grave LCA could be developed (incorporating effects from transportation, installation, usage and disposal), using the cradle-to-gate LCA as part of the input data. 201002820 - 1.1

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
This preliminary study addresses the life cycle sustainability analysis subproject of the Woody Biomass Innovative Project, which proposed to assess the future bioenergy potential for British Columbia from a broad perspective that includes energy, greenhouse gas considerations and climate change, impacts on soil and biodiversity, and socio-economic sensitivities and to consider the need for guidance and policy development. This preliminary study reviews currently available assessment methodologies and proposes a framework for a life cycle sustainability assessment of current and emerging wood-based biofuel products used in three sectors (i.e., residential, institutional, and industrial) in British Columbia. In addition, this study defines data requirements and data availability for a detailed assessment, and outlines the possible policy implications that might be drawn from a detailed study.

Abstract
This report reviews life cycle assessment (LCA) based regulatory approaches that have been adopted in several countries to evaluate and improve environmental impacts of cosntruction products and buildings. Recommendations are provided for incorporating LCA into Canadian regulations (including the National Building Code of Canada), and for enhancing building LCA guidelines to address principles of consistency, simplicity, and representative data which can improve the effectiveness of LCA to achieve regulatory objectives. This work supports the project need of guidance for performance-based design to accelerate the introduction of wood-based systems. The findings of this review can be used to help accelerate the adoption of life cycle-based regulations for buildings and infrastructure in Canada.
