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建造的，带有负载。砖贴面安装在木结构的外面，为木结构房屋提供砖饰面外观。砖贴面是许多房主的首选选择，因为它不含维护，并且为建筑信封提供了优雅的外观和良好的绝缘介质。砖贴面还提供了改进的防止雨，风和火的保护。架子角是安装在建筑物木框上的钢C形构件，以支撑砖贴面并将砖饰面的负载转移到木框结构上。架子角的安装需要安装钢紧固件的安装，该钢紧固件通过螺栓拨动，这些螺栓需要穿过木框，进入建筑物的信封，形成热桥。这些热桥允许内部热量（在冬季）和房屋的凉爽空气（在夏季）逃到外部大气中，因此，丢失了用于加热和冷却的大部分能量。这项NSERC研究将进行实验和数值（计算机模拟）研究，以开发用于安装架子角度的热有效连接。目的是减少用于供暖和冷却我们的房屋的能源损失，并帮助加拿大到2050年实现净零能量建筑物和净零温室气体排放的目标。这项研究将由两位大师的学生执行接受绿色砌体建筑和环境可持续建筑信封的培训。这两位工程专业的学生将在温莎大学的S. Das博士和Alberta Masonry委员会的M. Hagel博士的指导下工作。这些训练有素且熟练的学生将能够弥合加拿大的技能差距。
