1128023 This project supports a cooperative research project by Dr. James Martin, Dr. Guney Olgun both at Virginia Tech. and Dr. Amr Darrag, Cairo University, Egypt. They plan to conduct research on Geothermal Energy Piles as a new sustainable green Energy solution for buildings, especially in the Middle East. There is a strong interest around the world in exploring alternative energy sources. Among the driving forces are growing energy demand, depleting natural resources and the adverse effects of greenhouse gas emissions from fossil fuel consumption. Energy Piles are a relatively new deep foundation engineering technology designed to access and exploit the relatively constant temperature of the ground (i.e., they extract heat energy from the ground) for efficient heating and cooling of structures. In ideal conditions, they can reduce heating and cooling costs of buildings by as much as 80%, and simultaneously help reduce the problem of greenhouse gas emissions. Although the use of Energy Piles has seen steady increasing usage in Europe and Japan over the past decade, more research is needed before they can enjoy common usage worldwide. Intellectual merits: There is a need to investigate the long term thermo-mechanical behavior of energy piles. The collaboration with researchers in Egypt would advance research that the US PIs are currently conducting. The PIs plan to conduct a full scale field test which will improve understanding of the behavior energy piles, and to develop laboratory test equipment which will improve testing capabilities for energy pile, including continuing to conduct FEM analysis of energy piles. A workshop organized by the PIs has identified certain barriers to the wide use of these piles, such as the lack of long-term Energy Pile performance data, a lack of refined design and testing standards, a lack of region specific field case histories, a lack of awareness among owners and engineers, and widely varying regulations for installation of geothermal wells. This proposal will help addressing these issues. The project will expand the PIs' ongoing work, currently involving Europe and the US, by developing region specific field performance data needed to optimize Energy Pile design and promote usage in Egypt. Broader impacts: Currently there is reluctance by engineers, contractors and owners to incorporate energy piles in foundations because of concerns of the thermal effects on the load carrying capacities of the foundations. This research could help to reduce some of their concerns. The US PIs are working with the deep foundations industry for this purpose. The use of energy piles in building foundations will enhance green construction efforts directed towards increasing energy efficiency and reducing energy demands. The work will promote wider usage of energy piles in the Middle East and in the US. Energy Pile may be an important part to the development of net-zero energy buildings. The project involves a significant international collaboration, including unique educational opportunities for a PhD student at VirginiaTech and students at Cairo University, and will likely continue partnering with Deep Foundation Institute (DFI). The project will promote wider usage of this new technology in the Middle East where more efficient solutions for cooling are increasingly needed. Also, because this work involves an innovative energy technology, it has great potential to create Egyptian jobs in the field of green energy. The project would also help lay the groundwork for a joint degree program in civil engineering between Cairo University and Virginia Tech. The findings will be disseminated via journals, the Internet, and incorporated into academic courses and the PIs? professional short courses for ASCE, FERC, USACE, etc. Key partners in this effort will be DFI and the US Green Building Council (USGBC).

1128023 该项目支持弗吉尼亚理工大学 James Martin 博士和 Guney Olgun 博士的合作研究项目。和埃及开罗大学的 Amr Darrag 博士。 他们计划对地热能桩进行研究，作为建筑物（尤其是中东地区）的新型可持续绿色能源解决方案。世界各地对探索替代能源有着浓厚的兴趣。驱动因素包括不断增长的能源需求、不断消耗的自然资源以及化石燃料消耗造成的温室气体排放的不利影响。能源桩是一种相对较新的深基础工程技术，旨在获取和利用相对恒定的地面温度（即从地面提取热能），以实现结构的高效加热和冷却。在理想条件下，它们可以将建筑物的供暖和制冷成本降低多达80%，同时有助于减少温室气体排放问题。 尽管能源桩的使用在过去十年中在欧洲和日本稳步增长，但仍需要进行更多研究才能在全球范围内得到普遍使用。智力优点：有必要研究能源堆的长期热机械行为。 与埃及研究人员的合作将推进美国 PI 目前正在进行的研究。 PI计划进行全面的现场测试，以提高对能源桩行为的了解，并开发实验室测试设备，以提高能源桩的测试能力，包括继续对能源桩进行有限元分析。 PI 组织的研讨会指出了广泛使用这些桩的某些障碍，例如缺乏长期能源桩性能数据、缺乏完善的设计和测试标准、缺乏特定地区的现场案例历史、业主和工程师缺乏认识，地热井安装法规差异很大。该提案将有助于解决这些问题。 该项目将通过开发优化能源桩设计和促进埃及使用所需的特定地区现场性能数据，扩大PI目前正在进行的工作，目前涉及欧洲和美国。 更广泛的影响：目前，由于担心热效应对地基承载能力的影响，工程师、承包商和业主不愿意将能源桩纳入地基中。 这项研究可能有助于减少他们的一些担忧。 为此，美国 PI 正在与深层基础行业合作。 在建筑地基中使用能源桩将加强绿色建筑工作，旨在提高能源效率和减少能源需求。 这项工作将促进中东和美国更广泛地使用能源堆。能源桩可能是净零能耗建筑发展的重要组成部分。 该项目涉及重要的国际合作，包括为弗吉尼亚理工大学的博士生和开罗大学的学生提供独特的教育机会，并且可能会继续与深度基金会 (DFI) 合作。该项目将促进这项新技术在中东的更广泛使用，中东地区越来越需要更高效的冷却解决方案。 此外，由于这项工作涉及创新能源技术，因此在绿色能源领域为埃及创造就业机会的潜力巨大。该项目还将有助于为开罗大学和弗吉尼亚理工大学之间的土木工程联合学位课程奠定基础。研究结果将通过期刊、互联网传播，并纳入学术课程和 PI 中？为 ASCE、FERC、USACE 等提供专业短期课程。这项工作的主要合作伙伴将是 DFI 和美国绿色建筑委员会 (USGBC)。
