Abstract

A study was undertaken to evaluate the embodied greenhouse gas emissions of four different design options for the foundation of a residential modular building in the East Midlands, UK. The assessment considered the embodied carbon dioxide equivalent of material production (without and with Portland cement replacement using ground granulated blast furnace slag), transportation, construction works (such as soil excavation) and plant usage on-site and off-site. The findings indicated that helical piles and reinforced concrete slabs supported with expanded polystyrene were the most sustainable options (in terms of embodied emissions) compared to conventional strip and pad foundations. The study provides valuable insight into considerations and constraints that may arise when evaluating the sustainability of modular building foundations. It offers practical guidance for decision makers in the modular construction sector seeking to mitigate the environmental impact of their geotechnical design.

模块化建筑基础的基于排放的方案评估——案例研究

在英国东米德兰兹进行了一项研究，以评估住宅模块化建筑基础的四种不同设计方案的具体温室气体排放。该评估考虑了材料生产(不使用和使用颗粒状高炉矿渣替代波特兰水泥)、运输、建筑工程(如土壤挖掘)以及现场和非现场工厂使用的隐含二氧化碳当量。研究结果表明，与传统的条形和垫形基础相比，螺旋桩和膨胀聚苯乙烯支撑的钢筋混凝土板是最可持续的选择(就隐含排放而言)。该研究为评估模块化建筑基础的可持续性时可能出现的考虑因素和限制提供了有价值的见解。它为模块化建筑行业的决策者提供了实用的指导，以减轻岩土工程设计对环境的影响。

期刊介绍： Engineering Sustainability provides a forum for sharing the latest thinking from research and practice, and increasingly is presenting the ''how to'' of engineering a resilient future. The journal features refereed papers and shorter articles relating to the pursuit and implementation of sustainability principles through engineering planning, design and application. The tensions between and integration of social, economic and environmental considerations within such schemes are of particular relevance. Methodologies for assessing sustainability, policy issues, education and corporate responsibility will also be included. The aims will be met primarily by providing papers and briefing notes (including case histories and best practice guidance) of use to decision-makers, practitioners, researchers and students.
