Unraveling how the concept of circularity relates to sustainability: An indicator-based meta-analysis applied at the urban scale

Claudia Rebeca Binder Signer, Albert Merino, Valeria Superti

Cities account for 75% of resource consumption and 80% of CO2 emissions. With rising urbanization, achieving urban sustainability becomes crucial. The Circular Economy (CE) concept has been proposed to reduce resource consumption, although its link to sust ...

The challenges of studying change in carbon-intensive urban consumption practices: Exploring the dynamics of practice change and of normative considerations in knowledge production

Franziska Meinherz

Problem. To reach international greenhouse gas (GHG) emission targets, the carbon intensity of urban resource and energy consumption must be reduced. Technological innovation alone is not sufficient: The practices that constitute urban household demand for ...

A review of approaches to low-carbon transition of high-rise residential buildings in China

Yi Wang, Jean-Louis Scartezzini, Dasaraden Mauree

In developing countries with a large population and fast urbanization, High-rise Residential Buildings (HRBs) have unavoidably become a very common, if not the most, accommodation solution. The paradigm of HRB energy consumption is characterized by high-de ...

Active renovation strategies with building-integrated photovoltaics (BIPV). Application on an early 20th century multi-family building

Emmanuel Rey, Sergi Aguacil Moreno

Tomorrow's cities are already largely built, as much of the existing building stock – with a low level of energy performance – will still be standing in 2050. Urban renewal processes therefore play an essential role towards the sustainable transition of Eu ...
