This award supports a 2.5 day international workshop in Lausanne, Switzerland, January 10-12, 2013 for the purpose of exploring and advancing the use of Thermo-active Geotechnical Systems for Near-surface Geothermal Energy as a sustainable geotechnical engineering practice. Thermo-active geotechnical systems are a novel approach to exploit the heat storage capacity of the ground for efficient heating and cooling of structures. The venue of the workshop is École Polytechnique Fédérale de Lausanne in Switzerland. The workshop will be held in a discussion forum format rather than in a conference style setting dominated by presentations. About one-fifth of the event will consist of overview presentations and rest of the time will be devoted to breakout sessions and discussions on resolving contentious issues and exploring future applications of this technology. The main motivation for this international workshop is to discuss and identify the technical and non-technical barriers involved in the implementation of thermo-active geotechnical systems. This workshop will serve as a synergistic discussion platform to bring together researchers from the academia, practitioners, and industry and public agencies representatives, to identify and address the pressing issues. Participants will come from the US, EU, Switzerland and Japan. The diverse mix of attendees from different backgrounds will ensure that communication will be cross-disciplinary and multi-dimensional, while the attendees from different parts of the world will help in transferring practical experience from other countries which have successfully implemented this technology. The technical issues to be addressed in the workshop will include 1) Soil-structure interaction issues related to the design of thermo-active foundation systems, 2) Testing, evaluation and non-destructive verification of these systems, 3) Use of near-surface geothermal energy in dense urban environments with congested and closely spaced foundations, and 4) Future applications of thermo-active foundations; bridge-deck deicing, thermal treatment etc. The non-technical issues that are critical for the wider implementations of these systems are 1) Building code and green-certification issues 2) Environmental impact calculations, 3) Cost-benefit analysis, life-cycle cost analysis, long-term savings. Collectively, these discussion themes will help develop a synergistic dialogue between the workshop participants and create a platform for the discussion and synthesis of ideas for the future direction of research in this field. The main outcome of this workshop will be a series of technical papers along with a synthesis document summarizing the results of the discussion sessions, and a workshop website. This workshop focuses on this renewable energy technology. This has far reaching impacts than geotechnical engineering through reductions in energy use with wider implementation of this innovative technology. Utilizing energy foundations can ultimately provide a more secure and stable energy source than conventional energy sources, higher energy security for the electric power system, and reduce harmful CO2 emissions. The results of this workshop will have broad impact on the geotechnical engineering profession related to the use of foundation systems for heating and cooling of structures. The workshop has the potential to result in increased use of energy foundations on a broad scale in the United States and globally.

该奖项支持2013年1月10日至12日在瑞士洛桑举行的为期2.5天的国际研讨会，旨在探索和推进近地表地热能热活性岩土系统的使用，作为可持续的岩土工程实践。 热激活岩土系统是一种新的方法，以利用地面的储热能力，有效地加热和冷却的结构。 讲习班的地点是瑞士洛桑联邦理工学院。 研讨会将以论坛形式举行，而不是以演讲为主的会议形式。 大约五分之一的活动将包括概述演讲，其余时间将用于分组会议和讨论，以解决有争议的问题并探索该技术的未来应用。 这次国际研讨会的主要动机是讨论和确定在实施热活性岩土工程系统所涉及的技术和非技术障碍。 该研讨会将作为一个协同讨论平台，将学术界研究人员、从业人员、行业和公共机构代表聚集在一起，以确定和解决紧迫问题。 与会者将来自美国、欧盟、瑞士和日本。 来自不同背景的与会者的多样化组合将确保交流将是跨学科和多维度的，而来自世界不同地区的与会者将有助于从成功实施该技术的其他国家转移实践经验。 讲习班将讨论的技术问题包括：（1）与热活性地基系统设计有关的土壤-结构相互作用问题;（2）这些系统的测试、评价和无损核查;（3）在地基密集和间隔紧密的密集城市环境中使用近地表地热能;（4）热活性地基的未来应用;桥面除冰、热处理等。对于这些系统的更广泛实施至关重要的非技术问题是：1）建筑规范和绿色认证问题2）环境影响计算，3）成本效益分析、生命周期成本分析、长期节约。 总的来说，这些讨论主题将有助于在讲习班与会者之间开展协同对话，并为讨论和综合这一领域未来研究方向的想法创造一个平台。 研讨会的主要成果将是一系列技术文件，沿着一份总结讨论会结果的综合文件和一个研讨会网站。本次研讨会的重点是可再生能源技术。 通过更广泛地实施这项创新技术，减少能源使用，这比岩土工程具有更深远的影响。 利用能源基础最终可以提供比传统能源更安全稳定的能源，为电力系统提供更高的能源安全性，并减少有害的CO2排放。 本次研讨会的结果将对岩土工程专业产生广泛的影响，涉及到基础系统用于结构的加热和冷却。该讲习班有可能导致在美国和全球范围内更广泛地使用能源基金会。
