Internal heat given off by human beings, lightings and domestic appliances is an Important factor which must be taken Into account estimate of building heating loads. This study outlines the procedures for determining the internal heat from these source and calculates the amount of internal heat added to an heat Ing spaces. This investigation shows that a family of four has a typical hourly internal heat production which averages approximately 460 Kilo- calories an hour in our country.

Main objective of this study is to provide heating cost allocation method according to the amount of heating energy consumption in apartments. Heating energy consumptions are calculated by DOE-2.1A program. As a result, heat loss ratio in Ondol heating system, heating cost coefficients of apartments and its using method is presented. Maximum heating cost coefficient rate is 2.63.

The objectives of the study are to find out the thermal performance of Ondol and its heat transmission characteristics through the experiment between the conventional Ondol system and prefabricated Ondol system in apartments. The results of the study could be summarized as follows. ·The heat radiation efficiency of prefabricated Ondol is better than that of conventional Ondol. ·The prevailing intermittent heating system of existing apartments must be changed to the continous heating system to keep the living space comfort. ·The allocation of boiler matching with the real heating load and some developed system taking into account of partial efficiency are needed to obtain the best performance of boiler. ·It is worth changing the existing finishing materials of conventional Ondol to any other materials having good thermal sensation. ·It is to be desired that the intermittent heating system of existing apartments should be changed to the continous heating system. And in case of holding the intermittent heating system the running time of boiler must be enlarged.

Since the end of 1970s a lot of energy related regulations and measures for energy conservation of buildings was prescribed and abolished. But to ensure that the substantial energy conservation is accomplished, it is necessary to ensure that not only the regulations and measures have to be observed favourably but also they might be investigated through the process of post evaluation. The study for the purpose of post evaluation of present using regulations and measures could be summarized as following results. ·In the aspect of the performance standard against our component standard energy rating method of existing detached houses was suggested. ·Some fallacies on the calculation of annual heating and cooling load of apartments were pointed out and their improvements were presented. ·By the recent amendment of Code for design guideline of office buildings, unreasonableness on the existing Code was analyzed and its improvements are prepared. ·Unreasonableness of Energy Performance Index as a energy evaluation tool of buildings was investigated and analyzed.

The objective of the study is to present a certain method that could be classified the existing detached houses over 5 millions in our country by their energy efficiency. The method, will be called KHEES(Korean Home Energy Evaluation System), will contribute to save energy in residences effectively and will change the passive attitude of home owners' energy saving mind to the active one. The principal contents and the scope of the project are as follows. - Gathering project-related data including papers, reports and existing home energy rating systems of developed countries has done. - Field survey of the 21 existing detached houses in Daejon city was done to examine their present energy situation and their energy perfomance. - For the preparation of energy evaluation index a refrence house was designed by using various statistic data from the national census results. - After analyzing and calculating the yearly energy consumption rate of reference house and existing houses, the comparison between their rates has done. The principal results of the study are as follows. - A reference house of 89㎡ is designed, and its annual energy consumption rate is calculated to use as a comparison tool. - From the comparison of the energy consumption rate between the reference house use and the existing detached houses the fact that the annual energy consumption of the existing detached houses are more from 11% at minimum to 58% at maximum than the reference house. - The existing detached houses was classified into three groups according to their construction year such as before 1979, from 1980 to 1987. The comparison result of annual energy consumption rate among three groups shows the rate of preceeding group is less about 10% than the rate of succeeding group.
