本研究は、フランダースの住宅改修における循環型材料（再利用、リサイクル、バイオベースなど）の使用が、組込み炭素に与える影響をLCAで評価。従来材料と比較し、循環型戦略の環境便益と負荷を明らかにした。複数の影響カテゴリーを評価し、負荷の転嫁を防いだ。結果は、循環型改修の有効性を示唆する。
English
This paper evaluates the life cycle carbon footprint of circular material strategies (avoiding, reclaiming, recycling, bio-based) for renovating single-family houses in Flanders. It compares conventional and circular measures for each building envelope element, assessing multiple impact categories to avoid burden shifting. The results provide insights into the environmental benefits and trade-offs of circular renovation approaches.

📄 Abstract（原文）
As buildings are responsible for an important share of the energy use and related greenhouse gas (GHG) emissions in Europe, renovation of the building stock is a key priority in the coming decades. As these large-scale renovations will require a vast amount of materials, sustainable solutions for material use in renovations must be searched for. To date, the use of circular materials is put forward to reduce the embodied impact of building renovations. To get a better insight into the carbon footprint of building renovation using circular materials, the life cycle carbon footprint for these renovation solutions is studied in this paper. To avoid burden shifting, multiple impact categories have been assessed. For each element of the building envelope, a life cycle assessment (LCA) has been conducted of a renovation with conventional materials and four circular renovation measures, i.e., avoiding materials, using reclaimed materials, using recycled materials, and using bio-based materials. The results provide insight into the environmental benefits and burdens of these circular renovation approaches for single family houses in Flanders. This paper is expected to contribute to the debate on using circular strategies for renovation by highlighting their benefits and burdens.
