Differences in energy-saving benefits between the rich and poor: data-driven method to study equity of mandatory energy efficiency policy in Chongqing.

The equity of mandatory building energy efficiency design standards (BEEDSs) has not received sufficient attention, for there is little study emphasizing the equity between the rich and the poor from the perspective of mandatory energy policies. Therefore, this study is aimed at evaluating the heterogeneous effect of BEEDSs on the energy consumption of households with varying incomes based on household-level data (n = 1196) from Chongqing in China. The study indicates that the actual energy efficiency of the high-income group is 47%, whereas those of the middle- and low-income groups are 32% and 25%, respectively, compared to groups in the absence of BEEDSs.

Historical peak situation of building carbon emissions in different climate regions in China: Causes of differences and peak challenges.

The climatic conditions in different regions of China are complex and diverse, and the characteristics of building energy consumption in different climatic regions are quite different, leading to significant differences in the historical peak situation of building carbon emissions (BCE). Based on the statistical Mann-Kendall (MK) trend test method, this study evaluates the historical peak situation of BCE in different climate regions in China and discusses the reasons for the differences in the growth trends and peak situations of BCE in these regions. Furthermore, according to the characteristics of building energy consumption in different climate regions, the challenges faced by each climate region in promoting the peaking of BCE are highlighted.

Analysis of the vibration characteristics of tail beam of the hydraulic support under random coal gangue particle slip conditions.

To study the influence of the gangue content of coal gangue particles on the vibration signal of the tail beam under sliding condition, this paper combines three-dimensional(3D) laser scanning technology with the finite element method, establishes a finite element model of the real shape of coal gangue particles and the hydraulic support in top coal caving in LS-DYNA, analyzes the influence of gangue content on some characteristics of the acceleration signal on the tail beam in the time and frequency domains, and then studies the influence of the size and total mass of the rock, and the angle of the tail beam on the characteristics. The following conclusions are obtained: when the coal gangue particles slip on the tail beam, an increase in gangue content significantly improves the effective value of the acceleration signal of the tail beam in the time domain and the average power and average amplitude in the frequency domain. With different sizes, total masses, and tail beam angles, the increase in gangue content always causes an increase in acceleration signal characteristics.
