ABSTRACT: This paper aims to study the energy performance of basement structure of the currently under-construction Engineering Building of the University of Manitoba. The building is located at Fort-Garry campus in Winnipeg. A total of eighteen soil samples were collected at different locations and depths based on the geological profile of the ground. Thermal properties of the collected soil samples were obtained in the Geotechnical Engineering Lab using a K2-Pro device by Decagon. Heat losses are predicted for the below-grade envelope by considering thermal properties of soil and building materials. For that purpose, a numerical model was created based on construction drawings using COMSOL Multiphysics software. The applied approach includes the calculation of heat loss due to heat transfer through conductive mechanism. Different alternatives for insulation are suggested and compared.

RÉSUMÉ: Cet article vise à étudier la performance énergétique de la structure du sous-sol du bâtiment de la faculté de génie de l'Université du Manitoba. Le bâtiment est actuellement en construction et situé au campus Fort-Garry à Winnipeg. Au total, dix-huit échantillons de sol ont été prélevés à différents endroits et à différentes profondeurs en fonction du profil géologique du sol. Les propriétés thermiques des échantillons de sol collectés ont été obtenues dans le laboratoire géotechnique en utilisant un dispositif K2-Pro de Decagon. Ensuite, les pertes de chaleur sont calculées pour l'enveloppe souterrain du bâtiment en tenant compte des propriétés thermiques du sol et des matériaux de construction. À cette fin, un modèle numérique a été créé à partir des plans structuraux à l'aide du logiciel COMSOL Multiphysics. L'approche appliquée inclut le calcul des pertes de chaleur dues au transfert de chaleur par la conduction. Différentes alternatives d'isolation sont suggérées et comparées.
