Electrochromic　(EC)　glazing　provides　a　promising　solution　to　actively　adjusting　the　sunlight　and　radiant　heat　through　windows　in　response　to　building　visual　and　thermal　environmental　requirements,　and　control　strategies　play　a　critical　role　in　the　application　of　EC　technology　in　buildings.　However,　there　is　a　conflict　between　the　visual　and　thermal　environmental　requirements　for　EC　regulation　during　a　cooling　season.　To　solve　this　problem,　this　paper　developed　a　predictive　control　strategy　for　EC　glazing.　It　was　achieved　based　on　two　theoretical　models　which　could　predict　the　energy　performance　of　EC　glazing　at　different　tint　states,　including　the　solar　radiation　heat　transmitted　through　the　glazing　and　lighting　energy　consumption.　The　optimum　glazing　state　was　determined　based　on　real-time　minimized　energy　consumption.　Study　results　showed　that　the　predictive　control　strategy　outperformed　the　rule-based　control　strategy,　with　percentage　energy　saving　of　an　office　room　in　Beijing,　China　from　8.04%　to　12.78%　over　an　entire　cooling　season.　In　addition,　the　paper　evaluated　the　energy-saving　of　using　EC　glazing　under　the　predictive　control　strategy　in　28　Chinese　cities.　The　results　indicated　that　EC　glazing　was　highly　applicable　in　most　of　cities　with　energy　saving　from　2.35　kWh/m(2)　to　5.04　kWh/m(2)　over　an　entire　cooling　season.　(c)　2022　Published　by　Elsevier　Ltd.
