Traditional　and　vernacular　dwellings　in　many　places　of　China　are　proved　to　have　paid　more　subtle　attention　to　the　climatic　factors　in　locality.　This　article　summarizes　an　on-going　study　aiming　to　parameterize　the　climate-sensitive　features　of　traditional　dwellings　in　northern　China　and　to　explore　the　correlations　between　the　transformation　of　housing　morphology　and　the　change　of　climatic　conditions.　Mapping　techniques　can　be　used　to　identify　the　genealogical　zones　of　traditional　dwellings　based　on　climate-sensitive　features,　which　can　be　further　optimized　to　guide　local　housing　design　for　a　better　climate　adaptation.
