The building sector plays an important role in urban energy conservation and CO2 emissions reduction. Therefore, it is necessary to fundamentally explore the influencing factors and mechanisms of building energy consumption. This study aims to explore the impact of building physical form on energy consumption for buildings. Firstly, this study uses different types of buildings as research objects. And method of combining EnergyPlus and GIS is used to calculate building energy consumption. Then adopting regression analysis to evaluate the impact of six building form indicators on building energy use. The results show that building coverage ratio (BCR) has a positive relationship with point-type building energy consumption. And among mix-type buildings, sky view factor (SVF) has a positive impact on energy consumption, and building coverage ratio (BCR) has a negative impact on it. As for slab-type buildings, total wall surface area (WSA) has a positive effect on energy consumption, and building floor (BF) has a negative effect on energy consumption. However, the indicators are not enough to explain the building energy consumption, and further exploration is needed.

“…This is because high aggregation degree means that urban spatial form shows high population density, high building density and relatively high industrial concentration, which are more conducive to improving energy intensive utilization efficiency (Steemers, 2003;Wang et al, 2020). Moreover, the centralized residential space and industrial distribution form help to save the energy consumption of transportation, commuting and product transportation (Hankey and Marshall, 2010;Ma et al, 2015;Quan and Li, 2021). Second, the centralization of urban spatial structure will also have a positive impact on energy efficiency, because the higher the urban centrality, the more conducive to saving overall energy consumption and realizing intensive utilization (Chen et al, 2011;Mangan et al, 2020).…”

Rational planning and optimization of urban spatial form to achieve the goal of energy efficient utilization and carbon emission reduction is one of the important ways to improve energy efficiency. We deconstruct urban spatial form into centrality, aggregation and complexity, and analyze net effect and its heterogeneity of urban spatial form on energy efficiency with OLS, quantile regression model as well as grouped regression model. The results show that the effects of urban spatial centrality and complexity on energy efficiency are nonlinear. For the vast majority of cities, strengthening urban spatial centrality will significantly improve energy efficiency, but the growth rate will gradually decrease. The impact effect of urban complexity on energy efficiency has the characteristics of U-shaped trend with an inflection point value of 0.429. And for the three-quarters of urban samples, enhancing urban spatial complexity will reduce energy efficiency. The positive effect of urban spatial aggregation on energy efficiency is only significant in cities with high quantile for energy efficiency. In terms of urban heterogeneity, the positive effects of spatial centrality and aggregation on energy efficiency are more obvious in megacities with a permanent population of more than 5 million, and the negative effect of spatial complexity on energy efficiency is more obvious in small and medium-sized cities. Whether it is promotion or inhibition, the urban samples with high energy efficiency are more affected by the change of urban spatial form. Optimizing the urban spatial form is one of the important ways to improve the energy efficiency, and the policy setting should give full consideration to the urban heterogeneity and classified policies.

“…In terms of energy use and carbon emissions in compact cities, because of the properties of travel distance and trip mode, research has mainly paid attention to the transportation sector [20][21][22][23]. In studies concerning the effect of urban form on building energy consumption and CO 2 emission, however, urban compact form is rarely considered [24].…”

“…Currently, research on the effect of urban form on building energy consumption mostly focuses on 2D urban form [25][26][27][28]. The planar layout and pattern, such as building density and land-use pattern, are the main research objects [24]. The real urban form includes not only the 2D pattern but also the 3D attribute, such as the spatial geometry and the intensity of space utilization in a 3D space.…”

Continuous growth of building energy consumption CO2 emission (BECCE) threatens urban sustainable development. Urban form is an important factor affecting BECCE. Compactness is a significant urban morphological characteristic. There is currently a lack of research on the effect of urban three-dimensional (3D) compactness on BECCE. To clarify the research value of 3D compactness, we investigated whether 3D compactness has a stronger impact on BECCE than two-dimensional (2D) compactness. A total of 288 buildings of the People’s Bank of China (PBOC) were divided into 5 zones according to building climate demarcation. As BECCE is affected mainly by four aspects (socioeconomic condition, building features, macroclimate, and urban form), the BECCE driven by urban form (BECCE-f) in each zone was calculated firstly using the partial least square regression model. Normalized compactness index (NCI) and normalized vertical compactness index (NVCI) were calculated with Python to quantify urban 2D and 3D compactness within a 1 km buffer of PBOC buildings. The mean NCI and NVCI values of each zone were adopted as 2D and 3D compactness of this zone. Gray correlation analysis of the five zones showed that the connection between the NVCI and BECCE-f is stronger than that between NCI and BECCE-f. Based on this, we believe that the emphasis of later research should be shifted to urban 3D form, not just 2D elements. 3D form can describe the real urban form in a more accurate and detailed manner. Emphasizing 3D morphological characteristics in studies of the relationship between urban form and building energy performance is more meaningful and valuable than only considering 2D characteristics. The impact mechanism of urban form on BECCE-f should also be analyzed from the perspective of 3D form. This study also provides beneficial solutions to building energy saving and low-carbon building construction.
