The windows of a dwelling or building are one of the major sources of energy loss for both heating and cooling. Durabuilt Windows & Doors Inc. is an Edmonton-based manufacturer of windows that continues to develop new products that address this problem. All window manufacturers in Canada are required to meet a CSA standard for pressure differential across the window to limit the amount of window movement, air loss and ingress of water. All new products are tested to meet this standard before CSA approval. This research project will introduce to Durabuilt new optical instrumentation based on stereo vision to determine the three-dimensional displacement of the window during testing. Based on digital image correlation (DIC), the instrumentation can be used to determine not only the displacement of the window but also the surface strains that are generated. This is important information to determine the limitations of a current window design and also provides important insight into future directions for the design of a window. The research and development work will design and build an optimised imaging system for the unique testing requirements of the window. The system will then be used to carry out an initial investigation into window performance to highlight both the performance of the optical instrumentation as well as provide detailed information on the window design. This work is seen as a fundamentally new direction for the design and testing of windows.

住宅或建筑物的窗户是供暖和供暖能源损失的主要来源之一。 冷却。 Durabuilt Windows & Doors Inc. 是一家总部位于埃德蒙顿的窗户制造商， 开发解决这个问题的新产品。加拿大的所有窗户制造商都必须满足 CSA 窗户压差标准，用于限制窗户移动量和空气损失 和进水。所有新产品在 CSA 批准之前都经过测试以满足该标准。这项研究 项目将向 Durabuilt 引入基于立体视觉的新型光学仪器，以确定 测试过程中窗户的三维位移。基于数字图像相关（DIC）， 仪器不仅可用于确定窗口的位移，还可用于确定表面应变 所生成的。这是确定当前窗户设计的局限性的重要信息， 还为窗户设计的未来方向提供了重要的见解。该研究和 开发工作将设计和构建一个优化的成像系统，以满足独特的测试要求 窗户。然后，该系统将用于对窗户性能进行初步调查，以 突出光学仪器的性能并提供有关光学仪器的详细信息 窗户设计。这项工作被视为窗户设计和测试的全新方向。
