“…A block form is a material space form composed of urban buildings and their enclosed open spaces within a block area [41]. Urban block CEs are closely related to urban block form parameters, which has been proven by researchers [32,35]. Block form affects a building's CE and green space carbon sink by influencing the building energy demand [42,43] and the microclimate environment [44,45].…”

“…Yuan et al [34] quantified the relationship between the spatial forms of small cities and CE, and their research results showed that improving urban space compactness and reducing complexity and fragmentation had positive impacts on CE efficiency. Dong et al [35] researched the influence of urban morphology on CE, taking Beijing as an example, and the findings from their study revealed that in the northern region of Beijing, factors such as adjacency ratios, meshedness levels, and widths had significant positive impacts on CO 2 emissions. Ou et al [36] adopted panel data to analyze the effect of urban forms on CEs, and their research results showed that the irregularity of urban forms may also lead to more CEs, and the compact urban land development model was conducive to reducing CEs.…”

“…For pavilion The difference in the buildings' CEI caused by the block forms was 31.66%, which was slightly higher than the difference in the building energy consumption (BEC) in the operational stage caused by the block forms. The block form can have a significant impact, ranging from 10% to 30% or more, on the BEC [35,53]. In a study conducted by Xu et al [40] in Wuhan, China, the impact of block forms on the BEC during the operational stages of office buildings was examined.…”

“…Additionally the magnitude of the correlation coefficient r indicated the strength of the relevance Among these parameters, the BSF, FAR, BH, and BCR were considered representative form parameters. Taking Beijing as an example, Dong et al [35] investigated the influence of building form and street form on a building's CE by using a geographically weighted regression method, and their research findings indicated a negative correlation between the BCR/FAR and the CE. Their results supported the findings of this study.…”

Controlling building carbon emissions (CEs) is key to achieving the goal of carbon neutrality. Residential blocks are the main contributors of buildings’ carbon emissions and intensity, and thus can be manipulated to achieve carbon neutrality. This work aimed to evaluate the building carbon emissions intensity (CEI) levels of residential blocks using Rhino and Grasshopper and to quantify the relationship between the block form parameters and a building’s carbon emissions (CEs). Firstly, 48 cases were selected by stratified sampling, and they were classified by architectural typology. Secondly, the residential block morphological parameters and building carbon emissions were calculated. Thirdly, the relationship between the block form parameters and the building’s CE was quantified using statistical methods. Lastly, low-carbon planning strategies for residential blocks under the target of carbon neutrality were proposed. The findings showed that the influence of the block form parameters on a building’s CE was 31.66%. A building’s shape factor has a positive influence on its CE, and the floor area ratio, building volume–site area ratio, and building height have negative influences on its CE. A building’s shape factor, cover ratio, and surface–site area ratio synergistically impact its CE. The weight of a building’s shape factor on its carbon emissions was 3.84 times that of its cover ratio and 4.46 times that of its surface–site area ratio. The technology workflow proposed in this study can provide data in support of carbon emissions assessments and low-carbon planning strategies for urban blocks in other cities in China and worldwide.
