Research progress and prospects of energy-saving design of urban underground space light and thermal environment in the goal of carbon peak and neutralization
In the face of mounting challenges posed by global climate change and resource scarcity,attaining carbon peaking and carbon neutrality has become a collective objective for nations around the globe.Against this backdrop,research in the domain of building energy efficiency takes on increased significance.Exploration into urban underground spaces has bifurcated into two parts:energy-saving during the operational phase of buildings and using urban underground spaces for storing clean energy and sequestering carbon dioxide.Within this framework,energy-efficient design for urban underground spaces has gained considerable attention in recent years.The regulation of the thermal environment in underground spaces holds substantial implications for energy efficiency.Nevertheless,the present comprehension of the interplay between the thermal environment in underground spaces and energy-efficient design remains unclear.To realize the"Carbon Peaking and Carbon Neutrality"goals,a departure from generic building categories is imperative,necessitating an analysis of diverse behaviors and responses across distinct regions.Prioritizing the enhancement of thermal comfort in underground spaces,coupled with concurrent reductions in energy consumption and carbon emissions,forms the basis for achieving carbon peaking and carbon neutrality goals.In an effort to precisely dissect the focal issues between the thermal environment in underground spaces and energy-efficient design,this study employed the Web of Science core journal database and the Chinese Knowledge Network database.The study selected a total of 11 532 and 2 505 high-quality literature pieces for analysis,utilizing the CiteSpace tool to scrutinize pertinent domestic and international literature spanning the years 2012 to 2022.Findings reveal a substantial accumulation of research in the thermal environment energy efficiency field over the past decade.Recent studies have predominantly employed simulation experiments with machine learning and multi-objective optimization techniques to boost energy usage efficiency,exposing directional disparities in research focus.On an international scale,the emphasis centers around intelligent system control design and human behavior within residential,office,commercial,and tunnel engineering buildings.In China,research extends beyond energy efficiency,delving into specific types of building spaces,acknowledging variations in territorial resources.However,comprehensive studies addressing both energy efficiency in urban underground spaces and living conditions are scarce.Key issues in regulating the thermal environment in urban underground spaces remain ambiguous,and strategies for energy-efficient design in this context lack precision.The study categorizes research objects into four types(underground transportation spaces,underground commercial spaces,underground exhibition spaces,and other underground spaces)to clarify key factors that each space type emphasizes.Three overarching key issues are distilled:human-centric design,integration with nature,and building energy efficiency.The study advocates that underground space design must prioritize human comfort and health,sensibly regulate the thermal environment,enhance space utilization efficiency and occupant comfort using renewable resources such as natural light and airflow,reduce dependence on traditional energy sources,and decrease energy consumption and carbon emissions.Furthermore,optimization of building design,material selection,and equipment configuration should enhance the building's insulation and heat resistance while minimizing energy consumption.The study further posits that natural resource utilization establishes the upper limit for building energy efficiency,user demands determine the lower limit,and the estimation of regional human behavior and characteristics determines the theoretical maximum energy efficiency of architectural spaces.Consequently,a design process chain for the energy-efficient regulation of the thermal environment in underground spaces is proposed to tackle the challenges of high energy consumption and carbon emissions,providing insights to enhance energy efficiency and the quality of living environments in urban underground spaces.
