Research Award Title: Assessment and Redesign of Processes for Sustainable Construction Project AbstractThis project will create 'hybrid' life cycle models of the environmental implications of construction process activities. Input-output models function by considering a change in economic activity in a primary sector, and estimating the implications in that sector and all other sectors in the supply chain. Further, these models then link with other data (e.g. emissions, energy use) on a sector basis to link primary production with all secondary impacts in the supply chain. However these models are highly aggregate (e.g. there are a small number of construction sectors). Thus the estimates from input-output models may not accurately reflect the specific activities within a particular process. In this project, we will integrate an existing input-output model with process-specific data from existing inventories (e.g. BEES). The data from these various process-based inventory sources will act as substitutes for the estimates that come from the very average and aggregated input-output based models. This should make the overall estimates much better.There are several broader impacts expected from the research. The construction industry has a significant impact on resource use, environmental emissions, and energy use in the United States. The products of construction activity (e.g. buildings, roads) further contribute to impacts in these areas. By using the model and framework described above, more detailed information about the impacts of various construction process activities will be created. The result of this project will be freely accessible on the Internet to aid in public and private decision making issues related to the implications of construction. For example, someone trying to construct a 'green building' can see estimate of the overall environmental effects of various processes (e.g. transportation of materials to the site) and be more informed about which of these processes has the smallest environmental burden. In the longer term, such results could better inform and define the ways in which green building/construction projects are rated via a better understanding of the relative impacts of various processes. Finally, the model will be widely disseminated through public availability on the web, similar to the fashion in which the EIO-LCA model is used.

研究奖名称：可持续建设项目过程的评估和重新设计摘要本项目将创建“混合”生命周期模型的建设过程活动的环境影响。投入产出模型通过考虑初级部门经济活动的变化，并估计对该部门和供应链中所有其他部门的影响来发挥作用。 此外，这些模型还与部门基础上的其他数据（如排放、能源使用）相联系，将初级生产与供应链中的所有次级影响联系起来。 然而，这些模式是高度综合的（例如，建筑部门的数量很少）。 因此，投入产出模型的估计数可能无法准确反映特定过程中的具体活动。 在这个项目中，我们将整合现有的投入产出模型与现有库存（例如BEES）的特定过程数据。 来自这些不同的基于过程的库存来源的数据将作为来自非常平均和汇总的基于投入产出的模型的估计的替代品。 这应该会使总体估计更好。该研究预计会产生几个更广泛的影响。建筑业对美国的资源使用、环境排放和能源使用产生重大影响。 建筑活动的产品（如建筑物、道路）进一步加剧了这些领域的影响。 通过使用上述模型和框架，将创建有关各种施工过程活动影响的更详细信息。 该项目的结果将在互联网上免费提供，以帮助公共和私人决策与建筑的影响问题。 例如，试图建造“绿色建筑”的人可以看到各种过程（例如将材料运输到现场）的总体环境影响的估计，并更了解这些过程中哪些过程具有最小的环境负担。 从长远来看，通过更好地了解各种过程的相对影响，这些结果可以更好地为绿色建筑/施工项目的评级提供信息和定义。最后，该模型将通过在网上公开提供而广泛传播，类似于使用环境影响评估-长期合作评估模型的方式。
