For the study of heating system in newly constructed farm house, existing houses were classified as "high", "medium", "low" by the levels of insulation and heat load were calculated based on each of them. The available solar energy collected in the heat storage tank was calculated with the variation of the area of the collector, 20㎡, 30㎡, 40㎡ respectively. Weather data used in this study are air temperature, soil temperature and radiation energy on horizontal surface from Oct. 1974 to May 1979 in Kwang Ju. The results of this study are summarized as follows; 1. High insulation of a house reduces not only total quantity of heat load but also makes its peak flattened. 2. In order to elevate the self-supplying level of heat load by solar energy, a house should be highly insulated. Considering the range of above level 40∼50% during winter time and 50~70% through total heating period, "Medium-40" and "High-20" are within that range. 3. In the cases of "High-30,40", "Medium-40", auxiliary heating is not required more than half the number of total heating days. 4. In view of the equilibrium between the farm labour load and heating labour load, a farm house should be improved to the level of insulation, "High". 5. Auxiliary fuel would be sufficiently supplied by the rural biomass resources. 6. The most optimistic case in this study would be the case of "High-20" in engineering aspect, but in consideration of various uses of surplus heat, the case of "High-30".

As one of methodological approaches for objective and systematic evaluation for rural resources, a sequential system for significance determination of resources items was formulated using AHP (Analytic Hierarchy Process) as the base technique. By the system constructed in this study, the significance values were calculated for all items of standard goal system which had been presented in the first phase- paper of research works for rural resources evaluation. The results analysed and obtained in the study are summarized as follows; 1. In case that the number of resources items for evaluation are relatively large, stepwise matrix method is considered as the better one for pair-comparison works in view of evaluator's convenience and consistency. 2. The significance valuing results for most resources items showed a considerable difference between characteristic areas, especially in aspects of land and human resources, so being considered as wet reflecting the specific areal varieties, 3. On land resources, the items for industrial development and land use showed higher significance value, while natural environment resources the items for ecological varieties and on human resources the items for artificial facilities. However, lower-valued ones were the items for mineral stocks in land resources, for control and protection in natural environment resources and for lower-level culture heritage respectively.

This study, a sub-one of comprehensive research works titled under "Rural Resources Evaluation System", tried to propose a rational methodology for development of rating tabulation on evaluation items. Firstly, the database system for handling of original/processed data of each evaluation items was constructed, being mainly focussed on the possibilities of data acquisition and statistical treatment. The rating tabulation system developed in the study has the formalized evaluation classes as 2 or 5 for convenience/simplification of analysis works. For each evaluation item in lower step of the goal system, 5 types of rating technique were arranged, which were based on statistical analysis using mean and standard deviation values(Type I), its existence or not(Type II), relative significance of its holding volume(Type III), synthesized weighting scale of its quality and quantity(Type IV), and the others(Type V). And, standardized 4-steps procedure for rating tabulation was proposed. Finally, the rating tabulation system developed in the study was applied to each evaluation item of goal system, from which the numerically-valued ranking criteria was obtained.
