Background

The European building and construction sector is extremely resource-intensive. This makes the renovation of existing buildings, including the adaptive reuse of cultural heritage buildings (ARCH), important for reducing the materials and energy intensity of the sector. Currently, Europe is embarking on a Circular Economy (CE) strategy that directly affects the environmental indicators for buildings and landscapes, including ARCH. However, there is a misalignment between macro-level European CE policy goals and micro-level renovation and management of existing buildings and ARCH. The analysis shows that macro European Union-level indicators are too narrowly defined to effectively guide the implementation of CE at the micro-project level for ARCH.

Results

This policy study develops a comprehensive ARCH Circular Environmental Impact Indicator Framework to close this gap by: (1) defining the research question; (2) identifying the causal network; and (3) selecting the best indicators. The study compares Circular Environmental Indicators for ARCH projects to current and developing European management schemes. Best practices in environmental impact assessment at the project level are highlighted for the building and construction sector in Europe.

Conclusions

The proposed new framework is a comprehensive and suitable list of explicitly circular environmental indicators for ARCH. The framework has immediate practical applications for practitioners and policymakers interested in the CE regime for buildings in Europe.

欧洲文化遗产建筑的循环环境影响指标的未来

背景

欧洲的建筑业非常耗费资源。这使得现有建筑的翻新，包括对文化遗产建筑（ARCH）的适应性再利用，对于降低该行业的材料和能源强度非常重要。当前，欧洲正在实施一种循环经济（CE）战略，该战略直接影响包括ARCH在内的建筑物和景观的环境指标。但是，欧洲CE宏观政策目标与现有建筑物和ARCH的微观翻新和管理之间并不一致。分析表明，欧盟宏观水平的指标定义太狭窄，无法有效指导ARCH在微项目级别实施CE。

结果

这项政策研究制定了一个全面的ARCH循环环境影响指标框架，以通过以下方式弥补这一差距：（1）定义研究问题；（2）找出因果关系；（3）选择最佳指标。这项研究将ARCH项目的循环环境指标与当前和正在制定的欧洲管理计划进行了比较。重点介绍了欧洲建筑行业在项目级别的环境影响评估的最佳实践。

结论

拟议的新框架是ARCH的全面而适当的清单，明确列出了环境指标。该框架对于对欧洲建筑使用CE制度感兴趣的从业者和决策者具有即时的实际应用。
