项目摘要

There are ~22.2 million dwellings in England. One in five (21%) dwellings were built before 1919. About three quarters of these older dwellings have been subject to at least some major alterations since they were built, mostly extensions or loft conversions. A further 17.9% of dwellings was built between 1919 and 1944 and further 18% from 1945 to 1964. Dwellings built after 1990 account for just 12% of the stock. A large proportion of English housing stock is thus considered as heritage. Novel technologies for retrofit of our ageing stock would enable us to reduce its carbon emission and alleviate fuel poverty in a cost-effective way. This is essential for preservation of the heritage housing stock. The company Q-Bot has developed an innovative system for reducing heat loss through suspended timber floors that applies PU insulation from underneath. A robot is inserted into the floor void, surveys the void and condition of the floor, sprays insulation to the underside of the floor boards, and verifies the area and depth of insulation applied. This keeps the appearance of the floor (which could itself be considered as a heritage element) on the warm dry side, while maintaining ventilation within the floor void. Access can be made through an air vent in the outside wall, or through a small opening in the floor from within the property. This minimises disruption to residents and results in a typical in-stall time of 1-2 days.Initial 'in-house' experiments indicated that spraying insulation to suspended timber floors could reduce heat loss through the floor by 85%, reduce temperature stratification within the room, and reduce draughts in the property by up to 40%. The project will address the important question of the impact of the PU foam itself on the indoor environment and on occupants during the installation and afterwards. The currently used PU foam appears to contain ~30 Volatile Organic Compounds, some with unknown effects on human health. This could potentially create a risk to inhabitants due to exposure to chemicals that might, in the future, turn out to be (or have been) harmful. The proposal will develop suitable analytical techniques to explore the impact of various PU foams (and other sprayable insulation materials) on environmental and energy performance of retrofitted historic houses, and develop a comprehensive evaluation methodology to assess and model the effect of spray insulation on historic domestic properties.The project strongly supports the CDT Science and Engineering in Arts, Heritage and Archaeology as it supports the development of two of its strands: Data to Knowledge and Knowledge to Enterprise. It aligns with the EPSRC priorities 'Materials Characterisation' and 'Data to Knowledge

英格兰约有 2220 万套住宅。五分之一 (21%) 的住宅建于 1919 年之前。这些旧住宅中约有四分之三自建成以来至少进行过一些重大改造，大部分是扩建或阁楼改建。另外 17.9% 的住宅建于 1919 年至 1944 年之间，还有 18% 的住宅建于 1945 年至 1964 年之间。1990 年以后建造的住宅仅占存量的 12%。因此，英国住房存量的很大一部分被视为遗产。用于改造老化库存的新技术将使我们能够以具有成本效益的方式减少碳排放并缓解燃料匮乏。这对于保护遗产住房至关重要。 Q-Bot 公司开发了一种创新系统，通过从下方应用 PU 隔热层的悬浮木地板来减少热量损失。将机器人插入地板空隙中，测量地板的空隙和状况，将绝缘材料喷涂到地板的下侧，并验证所施加的绝缘材料的面积和深度。这使地板的外观（其本身可以被视为遗产元素）保持在温暖干燥的一面，同时保持地板空隙内的通风。可以通过外墙上的通风口或通过房屋内地板上的小开口进入。这最大限度地减少了对居民的干扰，通常安装时间为 1-2 天。最初的“内部”实验表明，在悬浮木地板上喷涂隔热材料可以将地板的热量损失减少 85%，减少房间内的温度分层，并将房屋内的气流减少多达 40%。该项目将解决聚氨酯泡沫本身在安装过程中和安装后对室内环境和居住者影响的重要问题。目前使用的 PU 泡沫似乎含有约 30 种挥发性有机化合物，其中一些对人类健康的影响未知。这可能会给居民带来潜在的风险，因为他们会接触到将来可能（或曾经）有害的化学物质。该提案将开发合适的分析技术，探索各种 PU 泡沫（和其他可喷涂隔热材料）对改造历史房屋的环境和能源性能的影响，并开发一种综合评估方法来评估和模拟喷涂隔热对历史住宅的影响。该项目大力支持 CDT 艺术、遗产和考古学科学与工程，因为它支持其两个分支的发展：数据到知识和知识到知识企业。它符合 EPSRC 的优先事项“材料表征”和“数据到知识”
