“…Therefore, in our framework we also include the design stage in buildings' life cycle stages. Overall, as illustrated in Figure 3, we consider three main lifecycle phases by taking into account the material [27], water [64][65][66], energy [67] and land [68] cycles: the pre-use phase, the use phase, and the next-use phase.…”

“…We envision a circular system in which there is no end of life; instead, all of the resources are reintroduced to the system multiple times by reuse or recycling with minimum resource inputs (see Section 4 for further arguments on this topic). [27,[64][65][66][67][68]. "+" signs on the water and energy cycles indicate potential surplus resource production.…”

“…Other examples of such pioneers include Rotor [24], Cycle Up [25], and Baubüro in situ [26]. However, the lack of cross-sector communication and coordination tools needs to be addressed in order to enable the broad implementation of a feasible circular design strategy in current construction practice [27]. Digitalisation could offer some of the tools needed.…”

“…• "Reuse": Reuse is concerned with reintroducing buildings and resources back into the system without needing major transformation and resource consumption. Reuse may occur in the same or a different location, and the function of the product may remain or change [27]. Strategies such as 'reduce primary resource inputs', 'design for reversibility', 'smart use of space' and 'urban mining' are partially built on reuse.…”

Digital technologies are considered to be an essential enabler of the circular economy in various industries. However, to date, very few studies have investigated which digital technologies could enable the circular economy in the built environment. This study specifically focuses on the built environment as one of the largest, most energy- and material-intensive industries globally, and investigates the following question: which digital technologies potentially enable a circular economy in the built environment, and in what ways? The research uses an iterative stepwise method: (1) framework development based on regenerating, narrowing, slowing and closing resource loop principles; (2) expert workshops to understand the usage of digital technologies in a circular built environment; (3) a literature and practice review to further populate the emerging framework with relevant digital technologies; and (4) the final mapping of digital technologies onto the framework. This study develops a novel Circular Digital Built Environment framework. It identifies and maps ten enabling digital technologies to facilitate a circular economy in the built environment. These include: (1) additive/robotic manufacturing, (2) artificial intelligence, (3) big data and analytics, (4) blockchain technology, (5) building information modelling, (6) digital platforms/marketplaces, (7) digital twins, (8) the geographical information system, (9) material passports/databanks, and (10) the internet of things. The framework provides a fruitful starting point for the novel research avenue at the intersection of circular economy, digital technology and the built environment, and gives practitioners inspiration for sustainable innovation in the sector.

“…The sourcing, processing, use and disposal of materials has other environmental impacts including pollution of air, water and land [1] which affect all the species on the planet including humankind. In Europe, the building industry is responsible for 35% of all solid waste [5]. This paper focusses on the energy consumption / carbon emissions associated with the built environment whole life cycle which is associated with materials.…”

Materials in the built environment – Whole life energy / carbon

Buildings are responsible for approximately 40% of global CO2 emissions – one quarter of these being Embodied Carbon, which is front loaded to the construction period (months) in comparison to operational carbon emissions which usually occur over decades. Emerging concern about this issue is noted to have driven recent guidance publications and a few countries are preparing legislation to address the issue. The opportunities with most impact lie at the planning and design stage and require a committed client to ensure that early decisions are carried through to completion. This paper analyses the whole life carbon emissions for four façade options in a case study. Three further case studies are analysed for the impact of material choice on embodied and operational carbon emissions. All case studies show potential carbon savings depending on material choice. Even with minor carbon savings for one unit, there is potential for increased saving across multiple units (e.g. hotels and dwellings). Finally, opportunities to utilize waste products are considered, not only reducing carbon emissions, but meeting the Circular Economy principle of “keep products and materials in use”.

Legitimation der kreislaufeffektiven Holzbauweise – Nachweis der Klimaschutzwirkung

Das Nachhaltigkeitsgebot fordert, dass nur maximal so viel Holz aus dem Wald entnommen wird, wie im gleichen Zeitraum nachwächst. Daher ist das jährlich zur Verfügung stehende Erntevolumen für die Verwendung im Bauwesen begrenzt, auch vor dem Hintergrund, dass andere Wirtschaftsbereiche verstärkt auf den Rohstoff zurückgreifen. Anzustreben ist dementsprechend die Maximierung der Kohlenstoffspeicherung als Summe aus dem im Wald gebundenen Kohlenstoff und der stofflichen Verwendung von Holz. Für das Bauwesen bedeutet dies die Langlebigkeit der Baukomponenten, indem die Ressource Holz kreislaufeffektiv eingesetzt wird. In diesem Aufsatz wird zum einen die strategische Herangehensweise zur Steigerung der Kreislauffähigkeit der Holzbauweise vorgestellt. Zum anderen wird der klimarelevante Nachweis der Notwendigkeit kreislaufeffektiven Bauens erbracht und mit einer dynamischen Bilanzierungsmethode nachgewiesen. Dazu wird für den Ressourcenverbrauch und das Treibhauspotenzial aufgezeigt, wie das kreislaufeffektive Bauen grundsätzlich und im Besonderen mit Holz quantifiziert werden kann.
