A strategy to combat the adverse effects of urbanization involves the installation of green roofs under different climatic conditions. The design and maintenance of green roof systems need to be tailored to the local climate. However, there is a scarcity of reports on the performance of plants under temperate monsoonal climatic conditions. This study follows the growth pattern of 28 species (18 non-succulent forbs and 10 succulents) grown at three substrate depths (10, 15, and 20 cm) over three years on an unirrigated extensive green roof, located in Beijing, China. The results of this study revealed that sustainable extensive green roof was realizable without irrigation in Beijing. In terms of plant adaptive strategies, the most successful plants in this study were the stress-tolerant species, followed by the ruderal species. While deeper substrate could facilitate the survival and performance of plants, substrate moisture content was more significant for the survival of plants in the dry and cold winter in Beijing. This study recommended the use of a substrate depth, which was at least 15 cm deep for unirrigated green roofs in Beijing.

Urban green roofs offer environmental and social benefits and provide resources for urban wildlife; however, how birds use green roofs remains poorly studied in Mediterranean cities. Here, we develop a 1-year study in Madrid, Spain, recording the birds that use both an urban green roof and the adjacent conventional roofs throughout the four seasons. We recorded a total of 17 bird species in the area, of which 8 use the green roof surveyed.

Owing to climate change, numerous regions around the world are expected to experience heightened occurrences of extreme events, including heat waves and intense precipitation. This will disproportionately impact the well-being of urban populations. The implementation of green roofs is actively considered as a viable climate adaptation strategy enhancing the resilience of cities.

Machinery operation is a major source of carbon emissions in building deconstruction. Early intervention through Design for Deconstruction (DfD) is crucial for emission reduction, yet the factors influencing these emissions are underexplored. This study integrates parametric BIM with multi-objective optimization (MOO) to assess mechanical carbon emissions in deconstruction.

The capacity of extensive green roofs (EGRs) in runoff reduction and pollutants control significantly decreased with increasing rainfall intensity. This is attributed to most of EGRs are the lower-drainage method and use a thinner substrate layer because of the structural load-bearing limits of buildings. Existing solutions depend on increasing the rainwater storage by thickening the substrate layer of EGRs, or replacing the substrate materials.
