摘要：
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.

摘要：
Though building-scale energy demand and indoor thermal comfort have been extensively covered by recent studies, the automation of middle- and larger-scale outdoor microclimate evaluation in parametric design is less covered. The relatively slow computation and the need for sophisticated expertise are some of the current issues. This paper proposes a Rhino–Grasshopper custom script to automatically compute spatial indicators for a quick thermal comfort estimation. The Galapagos evolutionary algorithm is used to optimize thermal comfort and select the best combinations of spatial indicators. In a summer case study located in Shantou, China, the proposed workflow was three times faster than a non-automated indicator calculation in ArcGIS, while the optimization method achieved 25% to 33% reduction in land areas under extreme heat stress. This automated process applies to existing states and new urban designs. It is adaptable to customized prediction models under different climatic zones.

摘要：
In the face of global warming and increasing impervious surfaces, quantifying the change of climate potential productivity (CPP) is of great significance for the food production planning. Targeting the Dongting Lake Basin, which is a key area for food production in China, this paper uses meteorological data, as well as Climate Change Initiative Land Cover, and Shuttle Radar Topography Mission digital elevation model to investigate the CPP and its changes from 2000 to 2020. The suitability of land for cultivation (SLC), and the land use/land cover change (LUCC) are also considered. The results showed that the CPP varied from 9,825 to 20,895 kg ha(-1). Even though the newly added impervious surfaces indirectly resulted in the decrease of CPP by of 9.81x10(8) kg, overall, the CPP increased at an average rate of 83.7 kg ha(-1) a(-1). Global warming is the strongest driver behind CPP increase, and CPP has played an important role in the conversions between cultivated land and other land types. The structure of land types tends to be optimized against this challenge.
