The research described was begun in response to the critical health problems of Alaskan aborigines-in particular, high tuberculosis incidence and death rates. The expenditure of millions of dollars on tuberculosis treatment for a relatively small population clearly indicated the need for basic measures such as adequate housing. After an analysis of the technical problems relevant to housing construction in remote Alaskan villages, four experimental houses were designed and constructed in the field. Each was occupied by an Eskimo family; in return for rent-free occupancy, the householders maintained the houses and kept temperature records. The house construction types were plank-and-beam; rough lumber; commercial wood-stave water tank; and an extremely light shell mounted on a stable foundation (which could be adjusted to compensate for frost heaving). The results of the studies are presented.
