Summary
The objective of this project is to identify the risk factors taken into account in the pricing of an insurance contract for a construction site. This project aims to synthesize the quantitative approaches used in practice and presented in academic research for the pricing of home insurance and commercial insurance. Then, we aim to identify the preventive measures that can be taken to reduce the impact of different perils in the insurance of a construction site in wood or other.

Assessing the Environmental Impacts of the Canadian Building Sector through Dynamic Life Cycle Analysis: Developing a Forward-looking Model for Greater Use of Wood Products

Summary
Several studies indicate that using wood from sustainable forest management in building construction both maintains or increases carbon sinks in the forest, temporarily captures carbon in buildings, and substitute more emitting materials or fuels. This strategy is interesting, but it is difficult to implement from a political point of view because its real benefits are complex to evaluate. There are several methods for evaluating the GHG impacts of a product over its entire life cycle, but there is no consensus on the method to be used to assess the impacts of GHGs from biogenic carbon - the carbon contained in living or dead biomass, such as wood. Many commonly used methods rely on simplifying assumptions that do not accurately assess the benefits that could accrue from increased use of wood products under construction. This PhD project will improve a promising method to evaluate the GHG impacts of biogenic carbon. Particular attention will be paid to the uncertainties of the method so that it provides all the information necessary for informed decision-making. The expected results could confirm that greater use of wood products reduces the environmental impacts of buildings, and that current methodologies are too simplified to inform policy making.

Summary
Understanding how roof and floor systems (commonly called diaphragms by engineers) that are built from Pacific Northwest-sourced cross-laminated timber (CLT) panels perform in earthquake prone areas is a critical area of research. These building components are key to transferring normal and extreme event forces into walls and down to the foundation. The tests performed in this project will provide data on commonly used approaches to connecting CLT panels within a floor or roof space and the performance of associated screw fasteners. Structural engineers will directly benefit through improved modeling tools. A broader benefit may be increased confidence in the construction of taller wood buildings in communities at greater risk for earthquakes.

Summary
The biomimetic approach in architecture explores the genius of organic natural forms resulting from a long process of environmental adaptation. These forms often have a high compactness and an optimal material / volume ratio in line with the importance of reducing the material in the building to limit its environmental impact in terms of energy and resources. What are the natural forms and processes of growth of the form most appropriate to the physical properties of wood? What design process promotes the integration of a biomimetic approach from the earliest stages of design? Based on a review of the main achievements claiming this approach, this project will develop a taxonomy of the different biomimetic typologies and identify the most promising in the context of a wood realization. A digital manufacturing process will be developed to reflect the complexity of natural shapes and flows in an organic architecture that optimizes environmental performance and aesthetics.

Summary
This project is expected to reveal if cross-laminated mixed hardwood and softwood species would have bonding properties similar to softwood CLT using commercial adhesives for timber laminating. The results will provide baseline data on adhesion properties of bonding mixed northern wood species.

Summary
CIRCERB (Chaire industrielle de recherche sur la construction écoresponsable en bois) has in the past mapped decision-making in public construction projects in Quebec. Using the same mapping approach, the project will highlight the steps in carrying out a timber construction project to identify hot spots where risk is important to the proponent, taking into account all stakeholders (material suppliers, general contractors, specialized contractors, etc.). In addition to presenting a broad picture of the wood construction, the project will identify the elements of the value creation chain on which optimization of business practices would be beneficial for wood construction.

Notes

Summary
Construction standards are governed by several factors. The National Building Code dictates the minimum to meet occupant safety issues. Energy issues are imposed by the energy efficiency standards of the Novoclimat programs of Transition Energie Québec. However, some developer-builders go further and enforce voluntary environmental standards such as LEED Version 4 or the WELL standard on occupant welfare. Many of these efforts are invisible to the occupier or the buyer because they are hidden in the building assembly, envelope or structure. Over the entire life cycle of buildings, these construction details will be important to the building operator, but their initial costs will also have an impact on the choices made during construction or acquisition. The project proposes to determine the added value of these quality approaches for the consumer. The project will consider key wood building systems by comparing minimum requirements, best practices and consumer perception.

Summary
Classifications of volatile products that may pose health and comfort risks to occupants tend to be restricted by current regulations. It seems important to sample air from concrete, wood and steel buildings to measure the compounds present. Ideally, measurements at different time intervals could be considered to qualify and quantify contaminant dispersion dynamics over time. The project aims to identify a possible advantage of wood construction in the face of air quality, to identify the main contaminants (quantity and toxicity) and to propose sampling and measurement techniques adapted to the building environment.

Summary
Structural engineered woods require the use of previously evaluated structural adhesives in accordance with a variety of standard methods (ASTM D2559, ASTM D7247, CSA O112.9, CSA O112.10, CSA O177, etc.). The basic assumption is that a bonded engineered wood product will have a performance equivalent to, or better than, the non-bonded product it replaces, regardless of the conditions of use (dry, wet, fire, etc.). Nevertheless, the results of cross-laminated wood (CLT) fire tests have shown that the requirements currently imposed on adhesives do not allow to limit lamellae detachment when CLT is exposed to fire. Traditionally, this behavior is not observed for glulam. It is essential to review the classification and performance criteria imposed on adhesives by submitting them to the various tests currently standardized. The analysis of the results may also be used to develop a new test method for adhesives exposed to high temperatures, depending on the anticipated use of the engineered wood product.
