Boarding　bridge　is　the　connecting　channel　between　boarding　gate　and　aircraft　cabin,　the　wall　of　the　boarding　bridge　was　usually　made　of　toughened-glass　while　the　roof　and　floor　were　built　by　the　lightweight　material　due　to　its　special　function　and　transparency　requirements.　However,　the　toughened-glass　and　lightweight　material　structure　resulting　in　a　huge/　large　energy　consumption　for　cooling　in　summer　or　heating　in　winter.　In　order　to　research　the　energy　saving　measures　for　boarding　bridge　air　conditioning,　in　this　study,　a　longitudinal　field　measurement　was　carried　out　in　one　3-storey　boarding　bridge　of　Beijing＇s　Capital　Airport,　Termi-nal-3.　During　the　field　measurement　period,　the　influence　of　some　potential　influential　factors,　such　as　outdoor　weather　conditions,　the　time-table　of　flights　arrival　and　departure　on　the　temperature　distribution　and　the　air　conditioning　load　of　the　boarding　bridge　was　identified.　The　field　measurement　data　can　be　used　in　further　research　for　exploring　the　energy　saving　measures,　optimizing　operation　and　management.　(C)　2017　The　Authors.　Published　by　Elsevier　Ltd.
