ABM Based Simulation Research Of University Dormitory Energy Consumption Management

With the progress of urbanization in China,the sharp increase in construction area inevitably leads to that building energy consumption.Among the many important determinants of energy consumption in building operations,occupant behavior is one of them.Therefore,the researches are of high theoretical and practical value concerning building energy consumption management from the perspective of occupant behavior.Based on the literature review,this thesis takes the college student behavior and dormitory energy consumption as the cut-in point.Firstly,the student dormitory energy consumption management system is analyzed from the perspective of the complex adaptive system(CAS)theory.Secondly,historical data of dormitory energy consumption are collected and analyzed,and students' energy-saving awareness and behaviors are investigated through questionnaires and interviews.Then,an agent-based simulation model of student dormitory energy consumption management system with JAVA in Anylogic is built.Finally,taking 400 studentdormitories in 2017 as an example,simulation experiments areconductedon different behavior energy saving strategies,different student interaction behaviors and two energy-saving education methods.After comparing building energy consumptions in different experiments,the following conclusions are drawn:The energy consumption of male dormitories is generally higher than female dormitories.The energy consumption of higher-grade dormitories is generally higher than lower-grade dormitories.The energy consumption of mixed dormitories is obviously higher than that of dormitories with students of the same grade and major.In summer,the energy consumption of some extravagant and wasteful dormitories reaches 2 to 3 times that of energy-saving and environment-friendly dormitories.All the above comparisons assertoccupant behavior`s significant impact on building energy consumption.Student energy saving behavior is lagging behind consciousness.Student energy saving consciousness has no significant gender or economic differences.The energy saving consciousness and behavior of the students with different political features are slightlydifferent.The difference in behaviors between male and female mainly lies in air conditioning temperature setting,computer using time length and frequency,and daytime light using.Studentbehaviortends to be influenced by roommates.As simulation experiments on different energy-saving strategies indicates,impacts of different behaviors on dormitory energy consumption are sequenced as: student occupance time > air-condition using time> air-condition set temperature> computer using time>computer standby time.Simulation experiments on student interaction behaviors show that strengthening the communication among students helpsoptimizetheir attitudes toward and awareness of energy-saving behavior.Simulation experiments on energy-saving publicity and education methods show that for the same publicity and education methods,increasing activity frequency saves more energy than adding participants.Much more energy is saved by holding energy-saving dormitory selecting activity than traditional publicity and education methods.Therefore,universities should increase the frequency of energy conservation education,enrich the forms of energy conservation education(such asselecting energy-saving dormitories),establish a system for publicizing dormitory energy consumption,and set up reward and punishment mechanisms,so as to strengthen communication among students and promote students' awareness of energy conservation,and finally promote energy conservation and emission reduction on campus.In summary,based on the CAS theory and ABM approach,this paper builds a simulation model of student dormitory energy management system targeting at student behaviorfollowing the bottom-up process,completes the simulation experiments on of behavioral energy-saving strategies and energy-saving education,and provides more directions for the future research of building energy conservation management.
