Conference: CAS-Climate: Ambient Energy for Buildings (AEB) Workshop: Beyond Energy Efficiency

将举办一个研讨会，讨论促进建筑物使用环境能源的机会和策略。环境能源系统和材料、设计、建筑、市场营销、金融、政策和社会科学方面的专家将齐聚一堂，提供他们的观点。研讨会的成果是发布一份白皮书，概述在研究、教育和传播方面的需求，以增加环境能源的使用，从而帮助解决迫在眉睫的气候危机。该研讨会将于2023年7月在华盛顿特区的能源部举行。建筑占美国碳排放量的近一半。此外，到2060年，由于建筑面积增加一倍，预计排放量将增加。全电零排放建筑并不能解决这个问题，因为到2050年，公用事业公司预计仍将燃烧化石燃料产生近一半的电力。当地收集的环境能源提供了一个转型的选择。入射到建筑物上的太阳能几乎是建筑物消耗的十倍。许多历史建筑和现代建筑的供暖和制冷都完全依靠环境资源。太阳能还可以加热水、烘干衣服、烹饪食物和提供照明。几十年来，许多建筑已经证明了100%的太阳能供暖。对于目前的技术，更广泛的采用可能需要在教育、培训、营销和激励方面进行创新。包括热管系统、聚合太阳能集热器、相变材料、透明绝缘、真空绝缘板和电致变色表面在内的新技术可以提高热学、经济和环境性能。通过改进设计工具，并将其纳入建筑性能标准和规范，可提高采用率。据估计，随着当地环境能源系统满足其非常适合的需求，到2050年，对公用事业级电力的剩余需求可能会比今天少。研讨会将讨论促进建筑物使用环境能源的机会和策略。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

A workshop will be held to discuss opportunities and strategies for promoting ambient energy use in buildings. Experts in ambient energy systems and materials, design, construction, marketing, finance, policy and social science will be assembled to provide their perspectives. The result of the workshop is to be a white paper outlining needs in research, education, and dissemination to increase the use of ambient energy and, thereby, help address the looming climate crisis. The workshop is to be held at DOE in Washington DC, tentatively during July 2023. Buildings account for nearly half of US carbon emissions. Further, emissions are projected to increase due to the doubling of built floor area by 2060. All-electric net-zero buildings will not solve the problem, because utilities are expected to still burn fossil fuel for nearly half of all electricity by 2050. Locally harvested ambient energy offers a transformational alternative. Nearly ten times more solar energy is incident on buildings than they consume. A number of historic and modern buildings have been heated and cooled entirely from ambient sources. Solar energy can also heat water, dry clothes, cook food, and provide lighting. 100% solar heating has been proven by numerous buildings over many decades. For current technologies, more wide-spread adoption may require innovations in education, training, marketing, and incentives. Thermal, economic and environmental performance could be advanced by new technologies, including heat pipe systems, polymeric solar collectors, phase change materials, transparent insulation, vacuum-insulated panels, and electrochromic surfaces. Adoption could be enhanced with improved design tools and incorporation into building performance standards and codes. It is estimated that with local ambient energy systems serving demands for which they are well-suited, the remaining need for utility-level electricity could be smaller in 2050 than it is today. The workshop will discuss opportunities and strategies for promoting ambient energy use in buildings.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
