Is it environmentally, economically, socio-culturally more sustainable to extend buildings’ lives or to build new? What are the specific challenges, potentials, and contributions for retaining existing buildings as opposed to their demolition and replacement? What are the drivers for the demolition of buildings? How can a more sustainable approach be created? How can retention and adaptive change be applied in different conditions and different scales (buildings, neighbourhoods, building stocks)?

Demolition / deconstruction has so far mainly been approached as a technical undertaking of engineering. Building preservation is primarily framed as historic conservation i.e. rarity, architectural quality, historic role, etc). Social scientists (e.g. Gilbert, 2009) have criticised mass-replacement policies and the consequences for underprivileged people who are dislocated. There has been relatively little problematisation both in- and outside of academia whether and when demolition should be performed, apart from Thomsen et al. (2011) and the RetroFirst campaign in the UK by the Architect’s Journal (2019).

Aims

The special issue will explore why demolition occurs with the aim to understand its environmental, socio-economic and cultural drivers, potentials and consequences, as well as policy and practices pertaining to avoiding demolition at different scales – supra-urban (country/region), urban (city/neighbourhood), building stock and building scale. How can planners and other stakeholders compare alternatives for densification without demolition i.e. by extending and infilling? What drives the replacement of existing buildings with new ones, what are the wider environmental, economic, and socio-cultural impacts on the sustainability of cities, and whether short-term financial gain is too privileged compared to other concerns. Submissions are welcomed that examine these phenomena in the different contexts of shrinking/growing communities. Contributions that explore the impacts of demolition from various viewpoints and multiple perspectives (urbanism, urban planning, obsolescence, resource efficiency, mass flows, embodied carbon, social value, etc.) are particularly welcome.

Context

Most of the developed world’s future cities already exist: most of the existing building stock will remain for decades if not centuries to come. However, in the sustainability discourse, the long-lasting nature of buildings is rarely celebrated. Older (domestic and non-domestic) buildings tend to be seen either as a problem and a threat, e.g. a contributor to climate change due to their allegedly excessive use of energy or, if they are heritage buildings, as being themselves threatened by the changing climate. Recently, new knowledge has emerged that challenges this perception, suggesting that older can potentially outperform new build as highlighted below.

First, as the focus is shifting from buildings’ operational energy consumption towards whole life carbon impacts, there has been a growing acknowledgement of embodied emissions (e.g. Röck et al. 2020). New build is inherently disadvantaged in this regard, as an existing building avoids further embodied emissions and waste generation. Second, the decarbonisation of energy supply is reducing the emissions from the in-use phase (Kuittinen & Häkkinen 2020), thus further increasing the significance of the embodied emissions.

Third, many existing buildings may already perform better than is the regular preconception (Sunikka-Blank & Galvin 2012) and there may be potential to reduce their consumption even further.

Fourth, due to differing temporal dimensions in which embodied and operational emissions are released, life cycle extension typically outperforms new build in the near future, i.e. in the timeframe most crucial to climate change mitigation (Heinonen et al. 2011).

Fifth, the existing economic arguments for demolition and rebuilding are contentious. Life cycle extension is typically more affordable for tenants, but redevelopment can create greater profits for the developer. Redevelopment increases property prices which often impacts negatively on affordability by displacing existing people and businesses. Not all incurred environmental, social and financial burdens are accurately converted into costs in our present economic system.

At the neighbourhood and urban scale, demolition of existing low- and middle-rise areas is often done to increase density. Denser urban structures in well-connected areas are believed to contribute positively to sustainability. However, the CO2 impacts for the two alternatives are rarely quantified in a satisfactory manner to account for embodied (both buildings and infrastructure) and operational (buildings and traffic) emissions and how they accumulate over time.

There is a pressing need for a wider and deeper understanding, but making comparisons is complicated and data intensive. Researching demolition and the prospects for its avoidance are further complicated by difficulties in accessing relevant data. Cadastral data on demolition is usually fragmented, not centrally collected and maintained, and/or lacks detail. Thus, different approaches and methods are needed in different contexts depending on the existence, availability and quality of data.

Suggested topics

The suggested topics for this special issue include, but are not limited to:

Dynamics of demolition vs. preservation on the building stock level

  • Spatiotemporal patterns of demolition vs. preservation
  • How vacancy may or may not be connected to demolition
  • Drivers, motives, incentives and/or barriers for demolition or preservation
  • Particularities in different types of contexts, e.g. shrinking or growing communities
  • More balanced approaches to economic, environmental and social criteria for demolition

Impact assessment

  • Environmental and/or economic performance of existing buildings in comparison to demolition and new build
  • Social and/or cultural consequences of demolition
  • Wider economic impacts of demolition and redevelopment e.g. higher costs of premises, externalised environmental costs
  • Demonstrable impacts of life cycle extension measures over the long term, e.g. a longer service life

Approaches and methods on the building level

  • Mechanisms of building obsolescence, their identification and mitigation (Thomsen & van der Flier 2011; Thomsen et al. 2015; Abrahamson 2016)
  • Untapped adaptation potentials of existing buildings and assessment thereof
  • Case studies of buildings, preferably representative multi-case studies of building types or ages prone to demolition
  • Case studies of existing buildings with minor interventions to extend their life and improve value e.g. extensions, accessibility improvements, etc.
  • Design qualities / morphological characteristics that enhance building longevity
  • Technical alternatives to demolition, e.g.  deconstruction, pre-planned disassembly, design for disassembly and adaptability

Policies, tools and skills

  • Planning and economic policies / strategies / criteria to support stewardship, continued use over demolition and their consequences
  • Policies, strategies and criteria for enhancing the longevity of the existing building stock
  • Policies, strategies and criteria for enhancing the longevity of new buildings
  • Appropriate data, indicators and measures for monitoring demolition and its avoidance as a part of policy implementation
  • Practical and professional skills needed to enhance the existing building stock and extend its life
  • The role of circular economic policies & practices on reducing demolition / extending service life

PhD Video Challenge: Two Minute Stories

Raymond J. Cole (University of British Columbia) reflects on the recent PhD Video Challenge and considers its wider benefits to doctoral students, the built environment community and wider civil society. It provides a valuable new path by which building-related research can be made accessible to a broad audience and a means by which PhD students can gain wide exposure of their research. Significantly, the Challenge also conveys a positive message about the research community by demonstrating how researchers strive to enhance the public's lived experience.

Fred Sherratt (University of Colorado) responds to the recent Buildings & Cities special issue ‘Modern Methods of Construction: Beyond Productivity’. It is easy to be beguiled by the promise of new technologies and the notions of ‘technological progress’. However, an essential role for the research community is to critically and robustly explore the consequences of new technologies for their potential impacts. Does the technology even deliver what it promises? These questions deserve societal discussion.
