ABSTRACT
The ASTA-research series into the costs of residential areas was carried out in Finland during time period 1975-1988. In the first phase (ASTA I) 24 residential areas in different parts of Finland were selected for study areas (Appendix 1). Besides this the buidling costs of these areas were investigated extensively and thoroughly. The subresearch ASTA II deals with the energy, maintenance and other operating costs of the
same 24 areas. In the summary research (ASTA III) the buiding, energy, maintenance, reparations etc. costs are combined in order to bring out the total costs of the areas.
