PROJECT T4–3-C11: INTUMESCENT COATINGS TO PROTECT ENGINEERED WOOD PRODUCTS

The objectives of this research are to identify effective intumescent coatings to protect susceptible components of Engineered Wood Products (EWP) from thermal degradation, develop appropriate quality control procedures to ensure that the coatings meet the target performance and evaluate the weathering behavior and resistance to mechanical damage of the coatings. It is a continuation of an exploratory study in collaboration with FPInnovations and related to another project on the fire resistant performance of reconstituted wood project with FPInnovations and Université Laval.

PROJECT T4–5–C10: DEVELOPING DURABLE BUILDING ENVELOPE ASSEMBLIES FOR CLT CONSTRUCTION

The objective of this research project is to develop durable building envelopes for the successful use of CLT construction in North America. It involves investigating the one-dimensional wetting and drying behaviour of CLT to provide guidance for field testing of CLT panels and to evaluate the thermal and moisture performance of CLT assemblies. A field study using a building envelope test hut will assess the long-term hygrothermal performances of CLT constructions of various configurations in different climates.

PROJECT T4–6–C10: DEVELOPMENT OF A METHODOLOGY TO CHARACTERIZE WIND-DRIVE LOAD ON MID-RISE BUILDINGS

The goal of the research is to develop a method to assess the wind-driven rain load on a given mid-rise building and to evaluate the impact of wind-driven rain on building envelopes so that appropriate technical solutions can be developed to reduce building envelope failures related to wind-driven rain. The project will develop and validate a CFD model to predict wind-driven rain loads on mid-rise buildings and develop a method to assess wind-driven rain loads on mid-rise buildings

PROJECT T4–7–C10: DEVELOPING DURABLE WOOD-FRAME BUILDING ENVELOPE SYSTEMS FOR NET-ZERO ENERGY READY BUILDINGS

The goal is to develop and advance knowledge and best practices in constructing energy efficient, cost effective and sustainable residential buildings with ensured long-term durability. The research objectives will 1) generate knowledge of the hygrothermal performance of energy-efficient wood-frame envelope systems, 2) help improve design and construction quality of the changed building envelope assemblies and prevent premature building envelope failures and 3) develop knowledge and help improve confidence in the construction industry in using innovative building materials and building envelope assemblies

PROJECT T4-8-C10: EVALUATION OF ENERGY EFFICIENT WALL SYSTEMS FOR MID-RISE WOOD FRAME BUILDINGS (PHASE II)

The overall goal of this research is to identify promising exterior wall assemblies that can meet future code requirements on overall wall thermal performance and provide required structural capability for mid-rise wood frame construction. In Phase I of this research (Value to Wood project), the research team has completed wall assembly selection, hygrothermal modeling and simulation, field experimental design, set up, and started the data collection from a muck up model, and laboratory testing on wall load bearing capacity. The specific objectives of the proposed project Phase II are threefold:Evaluating the long term hygrothermal performance of the selected exterior wall assemblies exposed in natural outdoor climate and to controlled indoor conditions, Characterizing the heat, air and moisture response of these wall systems in extreme weather condition or to challenging indoor conditions of humidity and pressure and Providing guidance on actual load bearing capacity (vertical load) of these wall systems to facilitate the mid-rise building design.
