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22％的温室气体排放，其中三分之二归因于太空供暖和冷却需求。用被动热存储（主要具有建筑物集成相变材料（PCM））的使用可以将满足这些需求的能量减少20-30％。尽管这种减少是显着的，但是在将这些材料安全地整合到传统组件中之前，仍然需要进行大量研究。为了解决这一差距，有必要改善建筑表面温度的可用数据，包括房间表面温度的趋势和空间分布。为了支持这一对更好数据的需求，卡尔顿大学高级建筑信封研究中心（CABER）的主任和PI Cruickshank博士开发了两个全尺度的全仪器测试室，每个测试室的尺寸为3 m x 3 m x 3 m，带有可更换的内部面板。目前正在建设的两个钱伯斯是相同的，可以完成比较测试（例如，一种典型的建筑材料，另一个建筑集成的PCMS面板）。但是，这些测试类目前尚无详细或实时监视房间中空间表面温度分布的功能。由于这些数据对于推动Cruickshank博士的NSERC Discovery Research的最新状态至关重要，因此她要求通过NSERC RTI计划索取76,310美元，以购买两个独特的，定制的设计的表面温度测量系统，将安装在Caber内的两个测试室中的每个测试室中。该系统由Viper Imaging设计和提供，每个系统都使用带有95°镜头的FLIR A70摄像头，连接到平底锅和倾斜系统上，从而使整个空间完全扫描，可以使用单个摄像头完成，从而为测试室的每个10 cm x 10 cm x 10 cm x 10 cm x 10 cm读取温度读数。耦合到摄像机是高精度IR温度计，它将用于连续校准IR摄像机，从而提高结果的准确性。这两个摄像机都将回到运行ViperTrack的一台计算机工作站，这是一种用于编译和分析IR摄像机数据的软件，该软件将用于提供详细的数据集用于分析和计算机模型验证。除了改善PCMS的实验和建模方法外，共同实用师DRS。 O'Brien和Gunay将在自己的研究中广泛使用该设备，该设备的重点是在变化的建筑条件下的事件舒适性和适应性建筑物控制对空间内能源使用的影响。拟议的设备对于在加拿大与攀登变化的斗争中的优先研究和开发新工具和方法的开发至关重要。鉴于2025年为达到加拿大政府的2030年目标所需的大量能源和排放目标减少，这尤其及时。
