Summary
The building sector is increasingly identified as being energy and carbon intensive. Although the majority of emissions are linked to energy usage during the operation part of a building's life cycle, choice of construction materials could play a significant role in reducing greenhouse gas emissions and other environmental end-point damages. Increasing the use of wood products in buildings may contribute to the solution, but their environmental impacts are difficult to assess and quantify because they depend on a variety of uncertain parameters. The present cradle-to-gate life-cycle analysis (LCA) focuses exclusively on a glued-laminated wood product (glulam) produced from North American boreal forests located in the province of Quebec, Canada. This study uses primary data to quantify the environmental impacts of all necessary stages of products' life cycle, from harvesting the primary resources, to manufacturing the transformed product into glulam. The functional unit is 1 m3 of glulam. This is the first study based on primary data pertaining to Quebec's boreal forest. Quebec's boreal glulam manufacturing was compared with two other LCAs on glulam in Europe and the United States. Our results show that Quebec's glulam has a significantly smaller environmental footprint than what is reported in the literature. From an LCA perspective, there is a significant advantage to producing glulam in Quebec, compared with the European and American contexts. The same holds true in regard to the four end-point damage categories.

Summary
Mobile digital tools (tablets and mobile phones) are ubiquitous in our lives. The potential of the cameras of these tools is under-exploited if we consider the geo-spatial information that they can provide to the information management systems (BIM) via cloud platforms for example. The images captured by these cameras can be combined with information from other sensors (gyroscope, accelerometers, etc.) and thus aligned with a BIM model. Many of these technologies are commonly used for robotic localization. The project would aim to assess whether current technologies could be used to track construction progress and identify non-conformities. The project would also determine the level of precision that can be achieved.

Summary
This paper illustrates arrangements of self-tapping screws to reinforce the mechanical behaviour of transverse compression. Several experimental approaches are studied such as the reinforcement below the support, beside the support or the combination of these two reinforcements. The last experimental approach is explored to solicit the shear over the entire height of the screw. These different approaches of reinforcement allow seeing a panel of constructive solutions to transverse compression reinforcement by screws. This panel allows adapting the type of reinforcement with the studied building.

Summary
In the development of an architectural concept, the perception of the client is a key element for acceptability. Wood often becomes a dominant architectural element. While decision-making on the choice of materials is often subject to budgetary considerations, it appears that the added value of wood in the building’s design, even on the basis of preliminary sketches and models (physical or visual), is not adequately delivered. The project proposes to explore augmented reality technology as a technique allowing greater acceptability of wood material during the initial design phases. The architectural component will explore the creative potential and quantify public perception when subject to the use of wood material in augmented reality.
