Buildings account for approximately 29% of Canada's total energy consumption and 22% of greenhouse gas emissions, two-thirds of which are attributed to space heating and cooling demands. The use of passive thermal storage, primarily with building integrated phase change materials (PCMs), can reduce the energy required to meet these demands by 20-30%. Although this decrease is significant, much research is still required before these materials can be safely integrated into traditional assemblies. To address this gap, it is necessary to improve the available data for building surface temperatures, including the trends and spatial distribution of a room's surface temperature. To support this need for better data, Dr. Cruickshank, Director and PI of the Carleton University Centre for Advanced Building Envelope Research (CABER), has developed two full-scale fully instrumented test chambers, each measuring 3 m x 3 m x 3 m, with replaceable interior panels. The two chambers, currently under construction, are identical, allowing for comparative tests to be completed (e.g., typical construction materials in one and building integrated PCMs panels in the other). These tests chambers, however, are not currently equipped to monitor the spatial surface temperature distribution in the room in detail or real time. As these data are critical to advance the state of the art and support Dr. Cruickshank's NSERC Discovery research, she is requesting $76,310 through the NSERC RTI program to purchase two unique, custom designed surface temperature measurement systems, to be installed in each of the two test chambers within CABER. The systems, designed and supplied by Viper Imaging, each utilize a FLIR A70 camera with a 95° lens, attached to a pan and tilt system, allowing for a complete sweep of the entire space to be completed using a single camera, obtaining temperate readings for each 10 cm x 10 cm area of the test chamber. Coupled to the camera is a high accuracy IR thermometer, which will be used for continuous calibration of the IR camera, improving the accuracy of results. Both cameras will feed back to a single computer workstation running ViperTrack, a software for compiling and analyzing IR camera data, which will be utilized to provide a detailed data set for analysis and computer model validation. In addition to improving the experimental and modelling methods for PCMs, co-applicants Drs. O'Brien and Gunay will make extensive use of this equipment within their own research, which focuses on the impact of occupant comfort under changing building conditions and adaptive building controls on the energy use within a space, respectively. The proposed equipment is critical to the success of the aforementioned research and the development of new tools and methods in Canada's battle against climate change. This is especially true and timely, given the substantial energy and emission target reductions required by 2025 to meet the 2030 objectives of the Canadian government.

建筑物约占加拿大总能源消耗的 29% 和温室气体排放量的 22%，其中三分之二归因于空间供暖和制冷需求 被动蓄热的使用，主要采用建筑集成相变材料 (PCM)。 ，可以将满足这些要求所需的能量减少 20-30%，尽管这种减少量很大，但在这些材料能够安全地集成到传统组件中之前，仍需要进行大量研究。为了解决这一差距，有必要改进可用的材料。数据为了支持对更好数据的需求，卡尔顿大学高级建筑围护结构研究中心 (CABER) 主任兼 PI Cruickshank 博士开发了两种完整的方法。 - 规模齐全的测试室，每个尺寸为 3 m x 3 m x 3 m，具有可更换的内部面板。目前正在建造的两个测试室是相同的，可以完成比较测试（例如，典型的建筑材料）。然而，这些测试室目前尚未配备用于详细或实时监测房间内的空间表面温度分布，因为这些数据对于推进现有技术至关重要。并支持 Cruickshank 博士的 NSERC Discovery 研究，她通过 NSERC RTI 计划请求 76,311 美元购买两个独特的、定制设计的表面温度测量系统，安装在 CABER 内的两个测试室中。由 Viper Imaging 设计和提供，每个都采用带有 95° 镜头的 FLIR A70 相机，连接到平移和倾斜系统，允许使用单个相机完成整个空间的完整扫描，获得每 10 个温度的温度读数测试室的面积为 10 厘米，与相机相连的是高精度红外测温仪，它将用于红外相机的连续校准，从而提高结果的准确性。工作站共同申请人 O'Brien 博士运行 ViperTrack，这是一种用于编译和分析红外摄像机数据的软件，该软件将用于提供用于分析和计算机模型验证的详细数据集。和 Gunay 将在自己的研究中广泛使用该设备，其重点分别是在不断变化的建筑条件下对居住者舒适度的影响以及适应性建筑控制对空间内能源使用的影响。所提议的设备对于项目的成功至关重要。讨论了研究和开发考虑到加拿大政府需要在 2025 年大幅削减能源和排放目标，以实现 2030 年的目标，这一举措显得尤为真实和及时。
