jismart2024073: Decarbonization of Heating Systems in Qingdao's Residential Districts: The Impact of Floor Area Ratio on Heating Load and Energy Efficiency

Abstract

The decarbonization of heating systems in Qingdao's residential districts is pivotal in reducing urban carbon footprints and enhancing energy efficiency. This study investigates the influence of Floor Area Ratio (FAR) on heating load and energy efficiency within the centralized heating system of Qingdao, China. Utilizing a combination of empirical data analysis and energy modeling, we assess how varying FARs affect the thermal demand and overall energy performance of district heating networks. Our findings reveal a significant correlation between higher FARs and increased heating loads, which subsequently impacts the energy efficiency of centralized heating systems. The study further explores mitigation strategies, including optimized insulation and the integration of renewable energy sources, to enhance the sustainability of district heating under different urban density scenarios. The results provide valuable insights for urban planners and policymakers aiming to design energy-efficient and low-carbon urban environments.
