Study On The Influencing Factors And Collaborative Governance Of Building Life Cycle Energy Consumption

With the continuous development and progress of society,people’s demands for quality of life have been continuously increasing.The increasing degree of urbanization has also driven the rapid growth of the number and scale of buildings.However,this trend has also led to the continuous increase in building energy consumption.China has proposed to reach the peak of carbon dioxide emissions before 2030 and strive to achieve carbon neutrality before2060.Therefore,in the context of achieving carbon peaking and carbon neutrality,the building industry will undertake more energy-saving and emission reduction tasks.The 20 th National Congress of the Communist Party of China clearly pointed out the importance of actively and steadily promoting carbon peaking and carbon neutrality,emphasizing the need to improve the control of total energy consumption and intensity,and promote clean and lowcarbon transformation in industries such as industry,building,and transportation.The current period is a critical period for promoting building energy conservation.Identifying the stakeholders and key influencing factors of the energy consumption throughout the entire life cycle of buildings,and further determining the impact of each influencing factor on the growth of the energy consumption throughout the life cycle,as well as the stakeholders who should bear key responsibilities for this,can help explore the energy consumption governance issues from a life cycle perspective,and enable the government to find the key points to promote energy conservation in buildings and formulate targeted policy measures.However,at present,research in China on the influencing factors of building energy consumption mostly focuses on the analysis of single factors,with little attention paid to the combination of stakeholders and influencing factors,and the existing energy governance research is mostly limited to the analysis of energy consumption in a specific stage.Therefore,this paper combines the influencing factors of building energy consumption with the stakeholders throughout the entire life cycle of buildings,and uses a combined qualitative and quantitative method to study the influencing factors and stakeholders that cause the growth of building energy consumption,providing an important supplement to the previous research that focused on single influencing factors.From a life cycle perspective,this paper also explores the energy consumption governance issues of each stakeholder,providing a basis for the formulation of energy conservation strategies and plans.The core contents of the paper include the following: calculation and analysis of the energy consumption of buildings throughout their entire life cycle;definition of the stakeholders involved in the entire life cycle of buildings;identification of the factors influencing the energy consumption throughout the entire life cycle of buildings;research on the extent of the impact of the factors affecting the increase in energy consumption throughout the entire life cycle of buildings and key stakeholder research;and policy recommendations for the coordinated management of energy consumption throughout the entire life cycle of buildings.The main conclusions are as follows:(1)The building industry is the largest energy-consuming sector in China.In 2020,the energy consumption throughout the entire life cycle of buildings was 2.307 billion tons of standard coal,accounting for 46.3% of the total national energy consumption and representing the sector with the highest energy consumption in the national economy.(2)Social factors,economic factors,and industrial structure factors have played a significant role in driving the growth of building energy consumption.Using the STIRPAT model,the factors that have led to the increase in building energy consumption were quantitatively studied,and a regression analysis model was established using ridge regression method.The research found that the above factors have a significant driving effect on the growth of building energy consumption.(3)All relevant stakeholders throughout the entire life cycle of buildings bear important responsibilities for the increase in building energy consumption.By studying the relationship between the factors influencing the increase in energy consumption in buildings and the relevant stakeholders,it was found that energy-saving policies aimed at a single stakeholder cannot significantly reduce the energy consumption throughout the entire life cycle of buildings.Only by coordinating all relevant stakeholders and achieving collaborative cooperation can building energy consumption be effectively reduced.Throughout the paper,the following innovations have been achieved:(1)From a whole life cycle perspective,exploring the issue of multi-agent energy consumption governance in buildings is a breakthrough in the current research which focuses only on the energy consumption of a single stage.Studying energy consumption in a single stage has certain limitations,as the interests and goals of each stage are not consistent.Achieving zero energy consumption in a single stage may increase costs and energy consumption in other stages.Therefore,studying multi-agent energy consumption governance throughout the entire life cycle is not just simply combining all stages,but also considering the collaborative governance of multiple agents throughout the entire life cycle.(2)By combining the factors affecting building energy consumption with the relevant stakeholders throughout the entire life cycle,this study provides an important supplement to the previous research which only focused on individual factors.Due to the complexity of the whole life cycle of buildings,which involves multiple stakeholders,their participation is crucial to reducing the overall energy consumption of buildings throughout their life cycle.This study defines the relevant stakeholders throughout the whole life cycle of buildings,identifies the main factors that contribute to the increase in building energy consumption,and analyzes their correlation.Furthermore,it determines the degree of impact of different stakeholders on the increase in building energy consumption and proposes collaborative governance strategies for multiple agents,which can help achieve energy-saving goals in buildings more effectively.
