Abstract
FPJoule is a web-based tool that can be used to evaluate the amount of energy contained in harvest residues according to their origin (species group and part of tree) and moisture content. The tool can also be used to quantify the financial advantages when using biomass as a fuel source compared to conventional fossil fuels. A more comprehensive spreadsheet model is also available to FPInnovations members. The latter version can be modified to match a particular facility, such as boiler efficiency.

Abstract
FPJoule est une application web permettant d’évaluer la quantité d’énergie fournie par des résidus forestiers selon leur origine (groupe d’essences et partie de l’arbre) et leur teneur en humidité. L’outil permet également de quantifier les avantages financiers liés à l’utilisation de la biomasse comme source d’énergie pour le remplacement des combustibles fossiles. Un modèle de feuille de calcul plus complet est également disponible pour les membres de FPInnovations. Cette version peut être modifiée pour correspondre à une installation particulière, comme l’efficacité des chaudières.

Abstract
Several RF pressing trials were successfully conducted in the pilot plant at the Vancouver lab of FPInnovations, which aimed at thick LVL manufacturing, use of lignin-based PF resin as a binder and new plywood pressing method. A number of 3.5-in thick LVL billets were first RF-pressed for heavy-duty packaging applications with a pressing time of being shortened to about 25 min but with satisfactory bending MOE and MOR properties. Lignin PF resin (with 20wt% phenol replacement ratio) was prepared and used to make 13-ply spruce LVL. Compared to the control, there was no significant difference in both panel flatwise and edgewise bending MOE and MOR, as well as panel delamination resistance, when the lignin-based PF resin was applied. Further plywood RF heating trials with aluminum plate separation of panels demonstrated that the inclusion of the plates can help increase the thickness uniformity of plywood panels pressed with RF heating. Economic analyses were conducted to determine the benefits of RF pressing for manufacturing LVL and plywood, and RF preheating of plywood. For RF pressing of LVL preliminary calculations demonstrated that RF pressing would generate aoubt $3.0 million CAD operating profit per year. It would also have 3.3% higher internal rate of return (IRR) and 1.25 years shorter payback period. For RF pressing of plywood, preliminary calculations indicated about $1.0 million CAD increase in operating profit annually for the RF pressing option, yielding a payback period of 3.95 years for purchasing and installing the new RF equipment. For RF pre-heating of plywood, the analysis showed that an increase of $4.7 million CAD in operating profit can be achieved annually and payback period is only 0.4 year. However, some further pilot plant work is required to establish the maximum closed assembly time of pre-heated plywood panels for industrial applications. PF adhesive formulations may also need to be changed in order to prevent glue dry-out after preheating.

Abstract
The objective of this project was to help Forintek members improve MDF manufacturing processes and maintain cost competitiveness by developing improved or new methods for mat preheating and/or humidification. MDF mat heating and humidification with steam (the H & H system) has demonstrated its great ability to increase press speed and hence production capacity in Ranger Board and WestPine MDF. Higher mat temperature allows shorter press time but it tends to drive some moisture out of the mat. Moisture content can vary significantly across the thickness of the mat depending on the conditions of the H & H system and the configurations of the formers, which have a strong influence on panel properties. It was observed that board formaldehyde emissions can be significantly increased as a result of using H & H, although emission levels can be effectively controlled by increasing the use of formaldehyde scavenger, or via resin modification, or both. Achieving the balance of mat temperature and moisture content and hence obtaining the optimal H & H conditions is challenging. Trial and error has been the only approach available to the mills so far. The approach of computer modeling, however, should be an excellent enhancement to the empirical approach. Based on mill data from WestPine MDF and Ranger Board, a preliminary computer model for mat heating and humidification with steam has been developed. It can be used to develop a deeper understanding of the individual process parameters and their interactions within the H & H system, improving process efficiency and product quality as well as training mill operators. In co-operation with Hydro Quebec, an experiment on microwave preheating of MDF mat was conducted. It was observed that moisture movement within the mat upon microwave heating was from the centre of the mat to both surfaces and towards the edges and corners. The moisture variation was much higher across the thickness of the mat than among different locations of a layer of the mat. The variations are thought to be related to the mat density profiles, electric field distribution and penetration depth. During hot pressing, PressMan profiles showed higher core temperatures for the microwave-preheated mat than the control for most of the press cycle. Based on the work carried out for this project, the following conclusions and recommendations are made: 1. A preliminary computer model has been completed for the MDF mat heating and humidification system at Ranger Board. It is now ready to customize to mill conditions. 2. A preliminary computer model has been completed for the MDF mat heating and humidification system at WestPine MDF. It is now ready to customize to mill conditions. 3. Microwave preheating of MDF fibre mat increases the initial mat temperature and re-distributes and moves moisture towards the mat surfaces. 4. As a result of moisture re-distribution, the moisture gradient and temperature gradient are in the same direction at the early stage of the hot pressing. Due to this effect of positive coupling between moisture gradient and temperature gradient, heat can be transferred significantly faster from the surfaces to the core and heat flux is also increased. 5. With microwave preheating, the increase of core temperature in MDF fibre mat starts earlier and the rate of the temperature increase is greater. 6. As a result of microwave preheating, hot press cycle time may be substantially reduced, leading to increase of production efficiency.

Abstract
This guide was jointly developed by FPInnovations; the Homeowner Protection Office, Branch of BC Housing; BC Hydro; FortisBC; and the City of Vancouver. It is based on the building industry’s design and construction practices and relavent research. The majority of the content was prepared by Chris Mattock of Habitat Design + Consulting Ltd. This guide focuses on design and construction strategies and detailed measures to improve home energy efficiency in British Columbia. The primary purpose of this publication is to provide guidelines for designers and builders who are interested in the design and construction of single-family and small multi-family buildings that are substantially more energy efficient and lower in environmental impact than traditionally built homes.

Abstract
A new heat flux sensor prototype was developed by Mark Ackerman in 2016. The new sensor can record heat flux data during the passage of a crown fire’s front due to changing the calorimeter material on the sensor. The new heat flux sensors were tested during an experimental burn at the Pelican Mountain FireSmart Research Area on May 31, 2017. This Info Note described the prototype deployment, data result and observations of the new heat flux sensors.

Abstract
In 2000, the Saskatchewan Department of Highways and Transportation (SHT) conducted two trials of heavy trucks equipped with tire pressure control systems and operating on rural roads. The Forest Engineering Research Institute of Canada (FERIC) participated in an advisory capacity and prepared this summary of the trials. The main objectives involved quantifying the potential benefits of optimized tire pressures in minimizing damage to rural roads, and offsetting the incremental road damage caused by larger capacity trucks carrying enhanced weights. Tire heating and fuel consumption were also examined.
