Development and demonstration of Automated Rapid Thermal Performance Assessments (RaThPAs) for scalable, accurate assessment of building fabric

皮博迪信托和联合生活地产服务有限公司认识到，现有的能源表现数据不适合国内大规模改造。如今，收集数据来准备和验证改造方案的成本太高、时间太密集，基于当前能源性能证书(EPC)的建模也不准确。为了以可扩展、经济高效的方式解决这一问题，皮博迪和United Living与技术领先的中小企业Kestrix Ltd.建立了合作关系。Kestrix将机器学习(ML)与基于区域的热图像捕获相结合，以快速评估建筑节能性能，消除了建筑织物性能测量的猜测工作。这为社会住房提供商(SHPS)、能源公用事业公司和国内改造价值链中的其他利益相关者降低了与改造规划和结果验证相关的成本和时间。通过该项目，Kestrix将开发创新的快速热性能评估(RaThPA)ML算法，以自动解读热像以获得能量性能。当与基于区域的热像测绘结合使用时，RaThPA可以立即解锁城市层面的建筑结构性能基准，而成本只有皮博迪的一小部分。皮博迪是一家监管104,000套住宅的小水电公司，而联合生活是一家顶级住宅承包商，它将提供密切的市场投入，并支持RaThPA技术的演示，从而使Kestrix能够在项目后迅速实现商业化。一旦这项技术被开发和测试，Kestrix将准备好在加快改造、减少燃料贫困以及推动英国向净零经济过渡方面发挥作用。

Peabody Trust and United Living Property Services Ltd recognise that existing energy performance data is not fit-for-purpose for domestic retrofit at scale. Today, collecting data to prepare for and verify retrofit schemes is too costly and time-intensive, and modelling based on current Energy Performance Certificates (EPCs) is inaccurate. To solve this problem in a scalable, cost-efficient manner, Peabody and United Living have formed a collaboration with the technology-lead SME, Kestrix Ltd.Kestrix is blending machine learning (ML) with area-based thermal image capture to rapidly assess building energy performance, taking the guesswork out of building fabric performance measurement. This drives down the costs and time associated with retrofit planning and outcomes verification for social housing providers (SHPs), energy utilities, and other stakeholders in the domestic retrofit value chain.Through this project, Kestrix will develop innovative _Rapid Thermal Performance Assessment_ (RaThPA) ML algorithms to interpret thermal images automatically for energy performance. When used in conjunction with area-based thermographic mapping, RaThPAs can unlock building fabric performance benchmarking at the city-level instantly, and at a fraction of the cost.Peabody, an SHP overseeing 104,000 dwellings and United Living, a top tier residential contractor, will provide close go-to-market input and enable demonstration of the RaThPA technology, enabling rapid post-project commercialisation for Kestrix. Once the technology is developed and tested, Kestrix will be ready to play its role in accelerating retrofit, reducing fuel poverty, and driving the UK's transition to a net zero economy.
