项目摘要

The research objectives of this CAREER project are to investigate impacts of decisions made by various stakeholders across a building’s lifecycle on material use, reuse, and recycle, and to develop a holistic approach to maximize recyclable and reusable material yields during the demolition phase. Many investigators have emphasized the importance of optimizing the use of materials throughout a building’s lifecycle, but most approaches have primarily focused on early stages (i.e., design and construction). This is because there is only a limited understanding of the impacts of collective decisions made by all relevant stakeholders (i.e., building owners, demolition contractors, and government agencies) across a building’s service life and the lack of a method to integrate their independent actions toward achieving downstream sustainability. This project addresses this knowledge gap. Specific research activities include advancing understanding of the decision-making process of stakeholders, (i) through the incorporation of recovered demolition material benefits within building owners’ maintenance, repair, and rehabilitation (MR&R) decision-making process, (ii) the quantification of productivity of different demolition options, and (iii) evaluating their impacts on recycling and reuse under different scenarios of environmental policy implementation. Focusing at a community level (i.e., in Tallahassee, Florida), this project will develop an integrated planning method for sustainable demolition material harvesting. The educational objectives are to instill in students and as much as possible in the general public a positive attitude about demolition waste as recoverable materials with untapped potential, and to educate the next generation of engineers to adopt sustainable practices. Educational activities include (i) developing educational modules on recycled construction materials and sustainable material harvesting for undergraduate and graduate teaching, (ii) engaging undergraduate and K-12 students in small-scale demonstration of the sustainable material harvesting concept, and (iii) promoting the benefits of recycled/reused construction materials and sustainable practices by working with student chapters. The educational activities are designed to improve the negative perception of demolition waste through interaction with students and the public.This project will create a holistic approach to sustainable demolition material harvesting, which not only advances phase-specific sustainability methods but also enables integration to maximize downstream sustainability across a building’s lifecycle. For the building use & occupation phase, this project will develop a new stochastic model to evaluate MR&R decisions made over a building's service life with respect to their contribution to the carbon- saving potential of recycling, and enable optimization of building owners’ decision-making toward sustainability. The project will quantify the time-performance of demolition methods under various management and operational conditions. Additionally, the project will develop a policy- planning framework, which enables interrelating and driving decision-making processes in a way that maximizes demolition material yields for recovery. The integrated material harvesting planning tool developed will be modified for use as an easy-to-comprehend learning medium by graduate students to address regional material issues (e.g., high material needs for rebuilding after a hurricane), thereby contributing to local environmental sustainability. Research and education outcomes will be disseminated nationally through the PI’s connection with natural hazards and construction engineering research communities. Minority and K-12 students will be engaged in research and education through FAMU-FSU College of Engineering's unique partnership with a minority-serving institution and FSU's existing programs. As part of the project, a new engineering-art collaboration will be created to improve students’ and the public’s perception of demolition waste.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.
该CAREER项目的研究目标是调查建筑物生命周期中各种利益相关者对材料使用,再利用和回收的决策影响,并制定一种整体方法,以最大限度地提高拆除阶段的可回收和可重复使用材料产量。许多调查人员强调了在建筑物的整个生命周期中优化材料使用的重要性,但大多数方法主要集中在早期阶段(即,设计和施工)。这是因为对所有相关利益攸关方作出的集体决定的影响只有有限的了解(即,建筑业主、拆除承包商和政府机构)在整个建筑物的使用寿命中的行为,以及缺乏一种方法来整合他们的独立行动,以实现下游的可持续性。本项目旨在解决这一知识差距。具体的研究活动包括提高对利益相关者决策过程的理解,(i)通过将回收的拆除物质利益纳入建筑物业主的维护,维修和修复(MR& R)决策过程,(ii)量化不同拆除方案的生产力,及(iii)评估在不同环境政策实施情况下,其对回收及再用的影响。以社区为重点(即,在佛罗里达塔拉哈西),该项目将为可持续的拆除材料收获制定一个综合规划方法。教育目的是向学生和尽可能向公众灌输一种积极的态度,即拆卸废物是具有未开发潜力的可回收材料,并教育下一代工程师采用可持续的做法。教育活动包括(i)为本科生和研究生教学开发关于回收建筑材料和可持续材料收获的教育模块,(ii)让本科生和K-12学生参与可持续材料收获概念的小规模示范,以及(iii)通过与学生分会合作,促进回收/再利用建筑材料和可持续做法的好处。通过与学生和公众的互动,教育活动旨在改善对拆除废物的负面看法。该项目将创建一个可持续拆除材料收集的整体方法,不仅推进特定阶段的可持续性方法,还可以实现整合,以最大限度地提高建筑物生命周期中的下游可持续性。对于建筑物使用占用阶段,该项目将开发一个新的随机模型,以评估在建筑物使用寿命期间做出的MR R决策对回收的碳节约潜力的贡献,并优化建筑物业主的可持续性决策。该项目将量化各种管理和业务条件下拆除方法的时间绩效。此外,该项目还将制定一个政策规划框架,使决策过程相互关联并推动决策过程,从而最大限度地提高拆除材料的回收率。开发的综合材料收获规划工具将进行修改,作为研究生易于理解的学习媒体,以解决区域材料问题(例如,飓风后重建的物质需求很大),从而有助于当地的环境可持续性。研究和教育成果将通过PI与自然灾害和建筑工程研究界的联系在全国范围内传播。少数民族和K-12学生将通过FAMU-FSU工程学院与少数民族服务机构和FSU现有项目的独特合作关系从事研究和教育。作为该项目的一部分,将创建一个新的工程艺术合作,以改善学生和公众对拆除废物的看法。该奖项反映了NSF的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
