项目摘要

Through the 2008 Climate Change act, the UK committed to reduce by 80% its carbon emissions. While great progress has been made so far, data suggests that reductions in emissions have been achieved through switching electricity production to greener, more environmentally friendly sources, such as offshore wind. Clearly, it is inevitable that, to achieve further reductions in carbon emissions, we need to look for improvements elsewhere, such as heating and cooling of buildings, which accounts for 25% of all UK final energy consumption and 15% of carbon emissions.Project SaFEGround aims to provide a template for reducing emissions associated to heating and cooling through the deployment of heat pumps. These are efficient devices capable of extracting heat from a storage medium, e.g. air for air-source heat pumps or the ground for ground-source heat pumps, and this is done with high efficiency, since for each unit of electricity consumed by the system, it is usual to get 3-4 units of heat. Clearly, these are more environmentally-friendly than boilers as they require only electricity, which, as mentioned above, is increasingly being generated from renewable and low-carbon sources. Therefore, SaFEGround will investigate how ground-source heat pumps can be coupled with civil engineering structures to deliver low-carbon heating and cooling in a sustainable, safe and efficient manner. To achieve this, SaFEGround will combine research on material science, heat pump technology, energy geotechnics, building energy systems modelling, whole-system modelling and finance, to demonstrate that ground source energy systems can play an important role in the UK's future low-carbon energy mix in a cost-effective manner.

通过2008年气候变化法案，英国承诺减少80%的碳排放。虽然迄今为止已经取得了很大进展，但数据表明，通过将电力生产转向更绿色、更环保的能源，如海上风电，已经实现了减排。显然，要进一步减少碳排放，我们不可避免地需要在其他方面寻求改进，例如建筑物的供暖和制冷，这占英国所有最终能源消耗的25%和碳排放的15%。SaFEGround项目旨在通过部署热泵提供减少供暖和制冷相关排放的模板。这些是能够从存储介质（例如，空气源热泵的空气或地源热泵的地面）提取热量的有效装置，并且这是以高效率完成的，因为对于系统消耗的每单位电力，通常获得3-4单位的热量。显然，这些比锅炉更环保，因为它们只需要电力，如上所述，越来越多的电力来自可再生能源和低碳能源。因此，SaFEGround将研究如何将地源热泵与土木工程结构相结合，以可持续、安全和高效的方式提供低碳供暖和制冷。为了实现这一目标，SaFEGround将联合收割机结合材料科学，热泵技术，能源岩土工程学，建筑能源系统建模，全系统建模和金融研究，以证明地源能源系统可以在英国未来的低碳能源组合中发挥重要作用。
