Provincial allocation of total building energy consumption in the context of"Double Control"of carbon emissions:A perspective from coupling of equity and efficiency
China's carbon peaking and carbon neutrality work has gradually changed from"Dual control"of energy consumption to"Dual control"of total carbon emission and intensity,which requires all sectors to properly handle the relationship between carbon emission reduction and energy security.In this context,exploring a provincial allocation scheme of total building energy consumption that considers both needs of regional development and carbon emission reduction is the key to respond to the national strategy of"Dual control"of carbon emissions and achieve safe carbon reduction in the building sector.Based on the perspective of equity-efficiency coupling,this paper proposes the principle of"appropriate balance between equity and efficiency"within regions and"equal probability of realization"among regions,and constructs a provincial allocation model of total building energy consumption with the constraint of total carbon emission target.Through Monte Carlo and numerical simulation techniques,the provincial quotas of building energy consumption in 2030 are obtained and compared with the provincial allocation result of total building energy consumption constrained by the total energy consumption target.The results show that in terms of the degree of satisfaction of constraints and the depth of carbon emission reduction potential realization,the provincial allocation scheme of total building energy consumption constrained by the total carbon emission target is the optimal choice that meets the multi-dimensional requirements.Its realization probability is 12％,public buildings and urban residential buildings will be the focus of future energy conservation and emissions reduction.
