The majority of residential houses in Canada are built with wood frames, which carries the loads. Brick veneer is installed on the outer surface of the wood building to provide a brick finish look for a wood-framed house. Brick veneer is a preferred choice by many homeowners because it is maintenance-free, and it offers an elegant appearance and a good insulation medium for the building envelope. Brick veneer also provides improved protection against rain, wind, and fire. Shelf angles are steel C-shaped members mounted on the wood frame of a building to support brick veneer and transfer the load of the brick veneer to the wood frame structure. Installation of shelf angles requires installation of steel fasteners called through bolts which need to pierce through the wood frame into the building envelope creating thermal bridges. These thermal bridges allow internal heat (in winter months) and cool air (in summer months) of the homes to escape to the outside atmosphere and thus, a large portion of the energy used for heating and cooling is lost. This NSERC research will undertake experimental and numerical (computer simulation) studies to develop thermally efficient connections for mounting shelf angles. The goal is to reduce the loss of energy used for heating and cooling our homes and help Canada in achieving the target of net-zero energy buildings and net-zero greenhouse gas emissions by 2050. This research will be executed by two master's students who will be trained in aspects of green masonry construction and environmentally sustainable building envelopes. These two engineering students will work under the supervision of Dr. S. Das at the University of Windsor and Dr. M. Hagel at Alberta Masonry Council. These highly trained and skilled students will be able to bridge the skills gap in Canada.

加拿大的大多数住宅都是用木框架建造的，木框架承载着负荷。砖饰面安装在木建筑的外表面上，为木结构房屋提供砖饰面。砖饰面是许多业主的首选，因为它是免维护的，它提供了一个优雅的外观和良好的绝缘介质的建筑围护结构。砖饰面还提供了更好的保护，防止雨，风和火。搁架角钢是安装在建筑物木框架上的C形钢构件，用于支撑砖饰面，并将砖饰面的负荷转移到木框架结构上。安装架子角需要安装称为贯穿螺栓的钢紧固件，该螺栓需要穿过木框架进入建筑物外壳，从而形成热桥。这些热桥允许房屋的内部热量（在冬季）和冷空气（在夏季）逃逸到外部大气中，因此，用于加热和冷却的大部分能量损失。NSERC的这项研究将进行实验和数值（计算机模拟）研究，以开发用于安装搁板角度的热效率连接。我们的目标是减少用于供暖和制冷的能源损失，并帮助加拿大实现到2050年净零能源建筑和净零温室气体排放的目标。本研究将由两名硕士生执行，他们将接受绿色砌体结构和环境可持续建筑围护结构方面的培训。这两个工程系的学生将在S博士的指导下工作。温莎大学的Das和M.哈格尔在阿尔伯塔马斯洛理事会。这些训练有素、技术精湛的学生将能够弥补加拿大的技能差距。
