为了优化建筑节能性能，我们需要了解建筑围护结构组件在加热、冷却、热分布和储存方面的运行方式。在本文中，我们开发了一种低成本的热扫描传感器，可用于在较长的时间内（整个气候周期）连续测量建筑物表面的热辐射。该传感器是电池供电的，并通过无线通信，允许它安装在建筑物的每个房间。我们展示了如何提供建筑物的CAD模型，多个扫描仪可以将每个表面的热映射缝合在一起，从而提供结构内热传递的高保真模型。当随着时间的推移进行分析时，这些模型可以提供广泛的洞察力，从HVAC效率，隔热性能和太阳能增益到占用估计，舒适度和材料耐久性。本文的贡献是设计和评估的扫描热成像传感器以及映射到标准的CAD模型，可以使用的能源模拟包的原始传感器值的过程。
In order to optimize building energy performance, we need to understand how building envelope components operate in terms of heating, cooling, thermal distribution and storage. In this paper, we develop a low-cost thermal scanning sensor that can be used to continuously measure heat radiation from surfaces in a building over extended periods of time (entire climate cycles). The sensor is battery operated and communicates wirelessly allowing it to be installed in each room of a building. We show how provided a CAD model of the building, multiple scanners can stitch together a thermal mapping of each surface providing a high fidelity model of heat transfer within the structure. When analyzed over time, these models can provide a wide range of insight into properties ranging from HVAC efficiency, insulation performance and solar gain to occupancy estimation, comfort-level and material durability. The contribution of this paper is the design and evaluation of a scanning thermography sensor as well as the process of mapping the raw sensor values onto standard CAD models that can be used by energy simulation packages.
