Many　studies　have　developed　green　strategies　and　technologies　for　urban　construction,　but　they　sometimes　ignored　the　intensive　and　dynamic　relationships　between　people,　buildings　and　the　natural　environment.　This　study　focused　on　how　to　generate　green　building　design　strategies　dealing　with　a　coupling　relationship　between　geomorphology　and　climate,　which　took　an　insight　into　the　built　environment　in　a　particular　locality　of　the　Yangtze　River　Delta　region　in　China.　First,　we　imported　climatic　data　from　six　cities　into　a　bioclimatic　evaluation　tool,　named　＇Weather　Tool＇,　to　assess　the　effectiveness　of　the　existing　passive　design　strategies　(passive　solar　heating,　thermal　mass　effects,　exposed　mass　and　night　purge　ventilation,　natural　ventilation,　direct　evaporative　cooling　and　indirect　evaporative　cooling).　Second,　we　employed　the　topological　method　to　identify　the　characters　of　the　vernacular　dwellings　by　interpreting　their　adaptations　to　the　local　topographical　and　climatic　conditions.　Consequently,　the　green　building　design　strategies　in　the　Yangtze　River　Delta　region　were　developed　through　the　macro,　middle　and　micro　levels　to　examine　group　patterns,　single-building　forms　and　building　components　in　a　particular　locality.　The　main　findings　were　shown　as　follows:　(1)　the　common　passive　strategies　played　a　role　with　different　effects　in　the　Yangtze　River　Delta　region,　which　acted　as　a　basis　for　choosing　the　most　effective　strategies;　(2)　the　local　dwellings　presented　a　comprehensively　sustainable　paradigm　with　architectural　prototypes　that　could　be　selectively　inherited　and　applied　in　contemporary　design.　(3)　Those　particular　strategies,　which　were　evaluated　through　bioclimatic　tools　and　developed　from　the　vernacular　dwellings,　gave　specific　suggestions　on　green　building　design　in　the　Yangtze　River　Delta　region,　providing　approaches　for　architects　and　developers　to　promote　more　environmentally　responsive　sustainable　development.
