“…Huang, Liu [19] believe that compared with no courtyard occupancy, full use of courtyards can reduce building energy consumption by 7.21% to 33.99% in various situations. Lizana, Lopez-Cabeza [20] found that the microclimate of the courtyard can greatly reduce the impact of urban overheating in the building, eliminating more than 88% of the uncomfortable time indoors. In Iraq, courtyards have been shown to provide occupants up to 38% more comfort throughout the year [21].…”

The spontaneous evolution of vernacular architecture mainly relies on the inheritance of architectural traditions and the innovative decisions of occupants, rather than the professional guidance of architects and the promotion of government agencies. This study introduces a new and rapidly developing phenomenon of spontaneous green evolution of vernacular architecture into the professional field, and conducts scientific research on its technical characteristics, system effects, and optimization methods. Based on the phenomenon of roofing of courtyards (CBR) in southern Hebei, we intervene from the professional point of view of architects, make the best use of the situation, and moderately intervene in its scientific development. By re-examining the adaptability of the open and closed attributes of courtyard buildings to specific climatic conditions and living patterns, the performance improvement and potential risks brought by CBR to local vernacular buildings are systematically analyzed, and the improvement strategies and promotion paths of CBR are explored. The research aims to form a relay and interaction between the professional intervention of architects and the spontaneous evolution of folk wisdom, and to explore the sustainable development of vernacular architecture. The findings help to improve the health and comfort of existing vernacular buildings, as well as to contribute to the improvement of rural human settlements.

“…If insulation and airtightness are improved without promoting better ventilation, less heat is dissipated and consequently overheating increases (López-García et al 2022). Fosas et al (2018), Samuelson et al (2020b), Lizana et al (2022) and Mehmood et al (2022) demonstrated how energy efficiency measures through insulation and airtightness could reduce overheating in well-designed buildings. However, if left unchecked, such measures create trade-offs in building performance, increasing overheating by more than 5%.…”

“…At the national level, infrastructure design can be better adapted by updating building 1086 Lizana et al Buildings and Cities DOI: 10.5334/bc.255 codes. The consideration of future climate conditions in building design, more thermal comfort variables in energy demand analysis and passive survivability analysis could help to address better adaptation to climate change (Lizana et al 2022;Zhang et al 2021). At the city level, appointing chief heat officers with the capacities to work across urban departments to put in place locally contextualised extreme heat plans and support urban solutions for sustainable cooling can enhance urban adaptation to increasingly frequent extreme heat (WEF 2021).…”

This article examines cooling in the built environment, an area of rapidly rising energy demand and greenhouse gas emissions. Specifically, the status quo of cooling is assessed and proposals are made for how to advance towards sustainable cooling through five levers of change: social interactions, technology innovations, business models, governance and infrastructure design. Achieving sustainable cooling requires navigating the opportunities and barriers presented by the incumbent technology that currently dominates the way in which cooling is provided-the vapour-compression refrigerant technology (or airconditioners). Air-conditioners remain the go-to solution for growing cooling demand, with other alternatives often overlooked. This incumbent technology has contributed to five barriers hindering the transition to sustainable cooling: (1) building policies based exclusively on energy efficiency; (2) a focus on temperature rather than other thermal comfort variables; (3) building-centric design of cooling systems instead of occupantcentric design; (4) businesses guided by product-only sales; and (5) lack of innovation beyond the standard operational phase of the incumbent technology. Opportunities and priority actions are identified for policymakers, cooling professionals, technicians and citizens to promote a transition towards sustainable cooling.

“…This land-based climate network has widely supported macro-and meso-climate studies. However, these stations are usually located in rural areas or near airports and with the growing in uence of urban areas on local meteorology, their data are less representative of the urban climate context 10 .…”

Urban heat islands are compounding the dangerous impacts of urban heat exposure globally. Cities across geographies require immediate and advanced urban climate information with enough resolution to detect risks and prioritise local climate adaptation interventions for their people. This research analyses the applicability of 550,000 citizen weather stations globally, a network 12 times larger than professionally operated weather stations, to measure urban climate at the highest spatio-temporal resolution and support climate adaptation policies globally. Cities with higher citizen data availability worldwide are identified, and a first open-source procedure in Python is proposed that cities around the world can use. The approach is validated in London, integrating temperature data from Netatmo and Wunderground platforms. The validation tests showed how pre-processing techniques improve citizen data accuracy, decreasing mean temperature deviation from 0.98ºC to 0.48ºC, inside the precision range of sensors. Data analytic methods identified significant implications of urban overheating in the case of London, increasing annual cooling degree hours by 60% in some urban areas, with different night and daytime hot spots. Aerodynamics and imperviousness affected urban overheating at night and daytime differently, requiring different localised interventions. Such large-scale application and scalability of open-access and readily available citizen data networks can efficiently support and monitor localised climate adaptation to mitigate the impacts of rising heat.
