Abstract
This report summarizes the experimental works that was carried out for a one-year research project developed as the continuation of previous research projects on the subject of light weight hollow core sandwich panels. The experiment focused on the investigation of creep behavior of light weight hollow core panel under long term static loading and high humidity conditions and its correlation with short term properties. Five types of surface panels were used, namely, 3.2 mm thick high density fibreboard with birch veneer on both sides, two thicknesses of M2 grade particleboard (6.3 mm and 9.5 mm) and two thicknesses of medium density fibreboard (6.3 mm and 9.5 mm). All panels were fabricated to the same final sandwich thickness of 45 mm using cell size of 12.7 mm Kraft paper honeycomb. The results of the experiment show that the strongest facing material used to make the sandwich panels was the 3.2 mm hardboard with wood veneer lamination on both sides running along the long axis of the panel and test specimen, followed by the 6.3 mm MDF and the 9.5 mm MDF. The experiment demonstrated that exposing the panels to high humidity could cause strength loss of up to half of the original strength. However, the result of the experiment also suggested that it would be difficult to accurately predict the long term creep behavior of the sandwich panels using their corresponding short term flexural properties as the correlation between creep deformation and flexural properties was rather weak under the testing procedure and condition used.

Abstract
The effects of natural drying in relation to the use of tarps on the moisture content of stacked softwood roundwood were examined. Biomass quality logs were stored for a period of 15 months in a mill yard in the Bas Saint-Laurent region of Quebec. The results of the study showed that the roundwood dried naturally during the summer season with moisture content at the end of the season below 30%. Tarping the roundwood piles during the fall and winter prevented an average increase in moisture content of 6%.
Abstract
Cette étude d'entreposage de la biomasse forestière visait à évaluer les effets du séchage naturel par rapport à l'utilisation de bâches sur la teneur en humidité de bois rond résineux au cours d'une période de 15 mois. Des billes de qualité biomasse ont été empilées dans un parc d'usine de la région du Bas-Saint-Laurent, au Québec. Les résultats de l'étude ont démontré que la biomasse séchait très bien naturellement pendant l'été avec un taux d'humidité en fin de la saison estivale en-dessous de 30%. La bâchage des empilements de biomasse au cours de l'automne et de l'hiver a permis d'éviter une augmentation moyenne du taux d'humidité de 6 %.

Abstract
A study conducted by FPInnovations in collaboration with the Coopérative forestière de la Matapédia (CFM) tested the use of tarpaulins on piles of round fir wood and to measure the effects on the natural drying of the logs. An experimental setup was installed in Sainte-Florence, in the Lower St. Lawrence, where the biomass was stored for 15 months (January 2012 to March 2013).

Une étude menée par FPInnovations en collaboration avec la Coopérative forestière de la Matapédia (CFM) a permis de tester l’utilisation de bâches sur des empilements de bois rond de sapin destiné à une mise en copeaux, et d’en mesurer les effets sur le séchage naturel des billes. Un dispositif expérimental a été installé à Sainte-Florence, dans le Bas-Saint-Laurent, où la biomasse a été entreposée pendant 15 mois (de janvier 2012 à mars 2013).

Abstract
This monitoring study was initiated to collect performance data from a highly energy efficient, six-storey building located in the coastal climate of British Columbia. This work focuses on the following objectives by installing sensors during the construction: · To provide information about the indoor environment of a highly energy efficient building · To provide field data about the durability performance of an innovative high energy efficiency exterior wall solution for mid-rise wood-frame construction · To provide information on the amounts of vertical movement in wood-frame exterior walls and interior walls below a roof/roof deck
