With　the　increase　demand　on　electricity　for　urban　residential　living,　compounded　by　factors　such　as　frequent　extreme　weather　events,　residential　electricity　demand　has　significantly　risen.　This　study　did　the　investigation　on　building　energy　consumption　habits　of　residents　in　Beijing　urban　areas,　combined　with　real　residential　electricity　bills　acquired　through　State　Grid　Corporation　of　China,　to　explore　the　energy　usage　patterns　and　influence　factors.　By　questionnaire　statistics,　households　were　divided　into　6　categories　and　the　electrical　appliances　usage　characteristics　and　energy　consumption　levels　were　analyzed.　The　research　identified　urban　residents＇　living　habits　and　electricity　usage,　revealing　significant　quantitative　relationship　among　electricity　consumption,　family　structure,　economic　level　and　so　on　with　principal　component　analysis　(PCA).　The　analysis　of　household　electricity　consumption　showed　that　households　simultaneously　including　workers,　school　students,　and　people　who　usually　stay　in　homes　(e.g.　retired,　unemployed)　had　the　highest　average　annual　energy　consumption　at　4226　kWh/household,　which　was　1134-1625　kWh/household　higher　than　homes　without　members　staying　in　during　office　hours.　The　combination　of　air　conditioners　(ACs)　and　electric　fans　is　found　to　be　commonly　used　in　residential　buildings,　and　this　method　is　highly　effective　in　energy　conservation.　Additionally,　it　is　indicated　that　46.5　%　of　residents　were　willing　to　participate　in　the　strategy　of　flexible　energy　use.　Amidst　the　comprehensive　electrification　trend　in　buildings,　this　study　is　of　great　significance　for　energy　conservation,　emission　reduction,　and　demand-side　management.
