"The question of environmental typology in conditions of mass-scale con-struction of multistorey apartmental buildings ( e.g. municipal ) has be-come extremely urgent. Environmental subject ( ES ) of dwelling ( consu-mer ) is a historical phenomenon and depends on many social and culturalparameters. It is possible to consider the historical dynamics of ES ofdwelling and its modern typology in connection with this dynamics. The his-tory of totalitarian environments brings to light a discrepancy between thereal and verbal ES's, the structure of the former being more complicated.Even with availability of the real subject typology it is impossible to workout an adequate environmental typology. The whole modern history of scienceand practice of dwellings convincingly proves this case.The traditional architectural environmental typology is mainly formed inaccordance with technological signs (technology of function or constructionwith prevailing economic criteria ). The function of social environmentalsubjects is modeled in attempts to elaborate a social typology environment.The result , as a rule, is inadequate to life activity of real subjects. Envi-ronmental approach to design of residential environments is considered as aunity of subject and his environment. Therefore the environmental typologycan be assumely obtained only through typology of subjects and environ-mental relations ( SEA ) . SEA is not every human activity in environment(thinking, e.g.) but only the one directly associated with it. That is why fac-tors of material culture in man-made environment together with culturaland historical traditions of way-of-life are dominant in the SER structure.A principal methodological transition from non-environmental subject ty-pologies to those of SEA is most important. The enviromental subject canvary from individual to social community of any level. In this sense the en-vironmental typology follows social in non-space problems an inverse wayfrom the real and project SEA defined by test system to various typologies of subjects is possible. The purpose of thic work is to elaborate the principlesand methods of environmental typology or, in my term, SEA typology. Theconflict between the subject and his real environment is the main principleof SEA typology. Some of the major parameters of the typology are a level ofreal environmental satisfaction, a character of prefarable environments,efficiency of life activity. It is important to assess the idea of people abouttheir future residential environments. It is also necessary to obtain a limit-ed number of SEA characteristics ( syndroms ) and to interprete them inresidential design. The first of these problems is auxiliary for it depends onintuition of the Investigator. The second one has been solved practically forenvironmental object "residential cell-flat" . The respective method hasbeen used for the last 10-12 years. It can be described together with re-sults of our investigations in 20 cities of the USSR and recomended for usein similar situations. An identical method for such objects of residential en-vironments as a residential house, a yard, neighbouring spaces etc. is beingcompleted. Its main problems are location and identification of social andenvironmental subjects in SEA dwelling system. The key principles and re-search ideas of this method can be further investigated and specified."
