To achieve the UK Government net-zero ambition requires an 80% reduction in carbon emissions by 2050\. Decarbonising domestic buildings is essential, as heating homes accounts for 7% of the UK's total energy demand. Heat-flux sensors measure heat transfer rate through surfaces, like walls and windows, to find the 'U-value' (i.e., thermal conductivity) of a building. This value quantifies the insulation performance of building materials.A growing application for heat flux sensors is their use in the construction of green buildings. One of the main aspects of a green building is that the power consumption of these buildings are bare minimal. To achieve this, it is necessary to determine where and how much heat (flux) is created at different parts of the building so that relevant construction material / HVAC operation can be applied for better heat distribution. This information is crucial for assessing energy efficiency and optimising a building's ongoing fabric performance.Unfortunately, current technologies for measuring the thermal performance of building fabrics are still too costly and complex, severely limiting the ability to properly assess, and thus effectively finance energy efficiency improvements. Our goal is to reduce the cost, and increase accessibility of heat-flux measurement technology for U-value measurement using new materials and processes.Vector Homes develop novel sensors and materials for green housing. This project will fund a collaboration with Printed Electronics and Tyrrell Building Technologies. Together we will develop a low-cost, fully-printed heat-flux sensor, by leveraging modern screen-printing, a high-throughput and industrially compatible manufacturing technology. We will design a 'smart-building' product around this sensor, for seamless integration into new-builds, to provide continuous thermal-health-monitoring. A disruptive technology for assessing and improving the real-life thermal envelopes of buildings.

为了实现英国政府的净零目标，需要到 2050 年将碳排放量减少 80%。国内建筑脱碳至关重要，因为家庭供暖占英国总能源需求的 7%。热通量传感器测量通过墙壁和窗户等表面的传热速率，以找到建筑物的“U 值”（即热导率）。该值量化了建筑材料的隔热性能。热通量传感器日益增长的应用是在绿色建筑的建设中的使用。绿色建筑的主要特点之一是这些建筑的能耗极低。为了实现这一目标，有必要确定建筑物不同部分产生的热量（通量）的位置和数量，以便可以应用相关的建筑材料/暖通空调操作以实现更好的热量分布。这些信息对于评估能源效率和优化建筑物的持续织物性能至关重要。不幸的是，当前用于测量建筑织物热性能的技术仍然过于昂贵和复杂，严重限制了正确评估的能力，从而有效地为能源效率改进提供资金。我们的目标是降低成本，并提高使用新材料和工艺进行 U 值测量的热通量测量技术的可及性。Vector Homes 为绿色住房开发新型传感器和材料。该项目将资助与印刷电子和泰瑞尔建筑技术公司的合作。我们将共同利用现代丝网印刷这种高吞吐量且工业兼容的制造技术，开发一种低成本、全印刷的热通量传感器。我们将围绕该传感器设计一款“智能建筑”产品，以便无缝集成到新建建筑中，提供持续的热健康监测。一种用于评估和改善现实生活中建筑物热围护结构的颠覆性技术。
