Er is een massale, wereldwijde migratie van bevolking naar (groot)stedelijke gebieden. Volgens de Wereld gezondheidsorganisatie (WHO) was in 1960 nog slechts 34% van de wereldbevolking gehuisvest in steden terwijl dat naar verwachting in 2030 reeds 70% zal zijn [1]. Daarbij is de ...

Design for Change and Circularity

Accommodating Circular Material & Product Flows in Construction

Journal article (2016) - Bob Geldermans

Circular building concepts, as proposed within e.g. Circular Economy and Cradle-to-Cradle frameworks, imply radical changes for the construction sector. Cradle-to-Cradle® in particular has put forward the idea of buildings as material banks, radically altering the way material flows need to be managed. The notion of material banks (temporary storage of materials that comprise the building assemblies) sheds new light on the value of building materials and products, and how to maintain and restore this. The basics are straightforward: high quality, pure material use and anticipated material regeneration routes. The implications for the supply and value chain, however, are significant, and research in this direction has only recently taken off. To smoothen the path to implementation, circular building principles may be combined with Design-for-Adaptability (DfA) guidelines, as developed over the last decades. DfA guidelines are rooted in enhanced resilience of the built environment on the one hand, and the associated constructive implications on the other. Synergy between the concepts of circularity and adaptability, with regard to the Dutch context, is at the heart of this paper. The main research question is: what are prerequisites for an effective performance of materials, products, services and buildings in the case circularity is a leading ambition? The research is structured around four interdisciplinary expert workshops in which knowledge and experiences were shared, discussed, tested and redefined, leading to a set of preconditions for circular building material and product flows. A key finding is that circularity-values emerge at the intersection of specific intrinsic properties (material and product characteristics) and relational properties (building design and use characteristics), whilst combining multiple parameters. In separation, neither intrinsic nor relational properties have decisive significance with regard to circularity; it is on the crossing where fulfillment is created. This paper finishes by discussing the findings from the perspectives of lifespan, monitoring, ownership, and standardization.@en

In onze traditioneel lineaire economie worden materialen gewonnen, verwerkt in producten en uiteindelijk gestort op stortplaatsen of verbrand in verbrandingsovens. Om de beschikking te kunnen blijven houden over materialen is een paradigmaverschuiving richting circulaire modellen ...

Circular Facade Refurbishment

Master thesis (2018) - Q.S. Henry, T. Klein, Bob Geldermans, T. Konstantinou, C.P. Dol

In de Paris Climate Agreement the goal is set to reach an energy neutral built environment by 2050. As a result, there is a high demand for energy neutral refurbishment of the existing housing stock. With the currently low refurbishment rate is it expected to take around 250 years to reach this goal. Due to the high initial investment costs of refurbishment, spread out over a short period of time, replacement and rebuilding is often the preferred option, while refurbishment is significantly less material consuming. Still the environmental impact of a refurbished building appears to be similar to the environmental impact of a new building, when looking at the material use spread out over the lifetime.

The Circular Economy is a solution to the problem of the current linear lifecycle of refurbishment, because it strives for an increased lifetime of the refurbishment by enabling reuse of components at the end of their functional service life and recycling of materials at the end of their technical service life. The Circular Economy aims to close and extend the loops of material cycles, in order to preserve value of materials, resulting in decreased raw material consumption and waste generation.

In this research the level of circularity of the 2nd Skin Façade Refurbishment system, which is a refurbishment strategy that wraps the building into a second layer of insulation, is examined. The level of circularity of the materials as well as the disassembly potential of the connections between the components and materials, have been analysed. Based on the assessment results, a Roadmap for circular façade refurbishment is developed. As validation of the approach, a design proposal is made for the Circular 2nd Skin Façade Refurbishment system, which is a universal refurbishment system that can be applied to different residential building typologies. The system is designed for future changes, as it enables reconfiguration of the façade arrangement and disassembly at the end of its functional lifetime. Instead of ending up as unrecoverable waste, the circular façade refurbishment system can be reused multiple times for the refurbishment of other residential buildings, exploiting the technical lifetime of the materials to the fullest.
