Abstract

The application of eco-design principles in the building sector is considered a promising way to mitigate its substantial environmental impacts. However, quantitative evidence for this mitigation potential is lacking. The objective of this study was to quantify the environmental performance of diverse eco-design strategies when applied to the building sector. A macroscale model capable of simulating the future demand for housing and related material flows within the urban building stock was developed based on an existing building stock model. These material flows were used to build inventories for a consequential life cycle assessment and, in turn, to quantify the potential environmental consequences of introducing eco-design strategies in the building sector, assessed across 16 impact categories. Model outputs have a high level of uncertainty but are still useful for decision-making, given the model's simplicity and transparency. The main results show that impact reductions can be obtained from specific uses of wood and wooden products, for example, when used for the walls in high-rise buildings, whereas using hempcrete for partition walls increases the impact. Although the use of adaptability or disassembly strategies can reduce impacts, this pay-off can only be obtained after a long period of implementation. In summary, the present study provides new quantitative insights into the ability of eco-design strategies to mitigate environmental impacts in the building sector.

应用于建筑领域的生态设计战略的环境绩效
在建筑领域应用生态设计原则被认为是减轻其对环境的巨大影响的一种可行方法。然而,目前还缺乏有关这种缓解潜力的量化证据。本研究的目的是量化各种生态设计策略在应用于建筑领域时的环境绩效。在现有建筑群模型的基础上,开发了一个宏观模型,能够模拟未来的住房需求和城市建筑群内的相关材料流。这些材料流被用于建立相应的生命周期评估清单,并反过来量化在建筑领域引入生态设计策略的潜在环境影响,评估涉及 16 个影响类别。模型的输出结果具有很高的不确定性,但鉴于模型的简洁性和透明度,仍可用于决策。主要结果表明,木材和木制品的特定用途可以减少影响,例如用于高层建筑的墙体,而使用麻混凝土制作隔墙则会增加影响。虽然使用适应性或拆卸策略可以减少影响,但这种回报只有在长期实施后才能获得。总之,本研究为生态设计策略在建筑领域减轻环境影响的能力提供了新的量化见解。

期刊介绍: The Journal of Industrial Ecology addresses a series of related topics: material and energy flows studies (''industrial metabolism'') technological change dematerialization and decarbonization life cycle planning, design and assessment design for the environment extended producer responsibility (''product stewardship'') eco-industrial parks (''industrial symbiosis'') product-oriented environmental policy eco-efficiency Journal of Industrial Ecology is open to and encourages submissions that are interdisciplinary in approach. In addition to more formal academic papers, the journal seeks to provide a forum for continuing exchange of information and opinions through contributions from scholars, environmental managers, policymakers, advocates and others involved in environmental science, management and policy.
