Using multivariate GARCH model, we estimate the relationship between the housing sale prices and lease prices in the Korean housing market. In the analysis of relationship between the rate of changes in sale and lease prices, the correlation coefficient of the apartment and detached house is higher than that of the townhouse. By housing type, the correlation coefficient between detached house and townhouse is higher than between apartment and detached house or apartment and townhouse. By housing size, there are no significant different results between the sales price and the rental price. The correlation coefficient between medium and small size is the highest in the apartment housing market, whereas the correlation coefficient between large and medium size is the highest in the detached housing market, resulting from the fact that people may be more interested in medium- and small-sized apartment and large- and medium-sized detached house. In the detached housing market, the correlation coefficient between large-medium size and medium-small size in the rental price is higher than that of sales price. This result implies that the process of the decision making between purchasing and leasing a house might be different.

This study was to identify the spatial and functional characteristics of kitchen and utility space plan in apartment housing. For this purpose, spatial arrangement and function of kitchen and utility space were analyzed according to the size of apartment unit. The results of this study were as follows; 1) The level of spatial separation among living room, dining room, and bedroom is higher in large-sized apartment. And diverse plans were applied for the kitchen of large-sized apartment. 2) To find out functional characteristics of kitchen space, furniture arrangement was analyzed. The I-type kitchen furniture is dominant for small-sized and medium-small apartment, and L-type furniture for medium-large and large sized apartment. 3) For most of the unit plans utility space is located on the balcony outside the kitchen. 4) Sub-kitchen and laundry are major function of utility space, but in case of balcony extention, the function of utility space is minimized. Recent plans for apartment housing shows various spatial arrangement and functions for kitchen and utility space.

Today, apartment is the primary housing type in Korea. In the past, there were many apartment floor plans in the same design way. There have been changes to complex and luxury plans in these days because people want to fit their own needs and wants to the plans. The primary purpose of this study is to analyze interior design trend of medium-large size apartment after year 2000. For that, this study used 7 different construction companies, 13 apartment complexes and 30 unit plan cases which were on sale from April 2007 to April 2008 in Seoul and the Metropolitan area. The results of analysis are as follows: First, most cases had 4LDK and 2bathroom with a dress-room. Second, characteristics of the interior design showed that the variety finish materials used in the units. For wall finish materials, wallpapers were used in mostly regardless in different areas. For floor finish materials, stone and tile were used in similar ratio in the entrance area whereas wood floor mostly was used in living room and kitchen areas. This study shows some significant characteristics of today's apartment even it has some limitations because of small amount of survey cases. More detailed and deeper study will be done continuously.

This study is to analyse the feasibility for providing Co-generation plant in Apartment Complex for 4 typical Apartment Complexes located Seoul metropolitan area, The selected complexes are three midium-large size Apartment[nearby 35pyoug of floor area] and one complex of small size Apartment[below 25 pyoung of floor area] for comparison. The necessary data for the study were collected with visitation of each site. The study showed very positive result for the three medium-large size Apartment Complexes of which the average floor area is more than 25 pyoungs, while negative result for the Complex of which average floor area is less than 25 pyoungs. Other than floor size it was found that the electric consumption density also influence the economic feasibility. In study the unit fixed cost of the energy produced from Co-generation plant is one third of the unit variable cost[fuel cost] and it seems better to select high thermal efficiency machine for Co-generation plant even with some higher cost of the plant.

The parking problem is caused by the parking demand. The ratio of parking demand at multi-family housing sites has been increased significantly, therefore several parking problems have occurred. The goal of this study is to investigate the parking demand per housing size of public-sized apartments, and to prepare that with the architectural regulations about parking supply. According to the results of this study, the parking demand of the small size housing unit(exclusive size：60 $m^2$ below) shows 1.09 car per the unit. and that of the medium size housing unit(exclusive size：60 $m^2$ over 85 $m^2$ below) shows 1.34 car per the unit. The parking demand of the small size housing unit was exceeded 56% more than the legal supply limit, and the parking demand of the medium size housing unit was exceeded 34% more. It is means that the level of architectural regulation about parking supply was not enough than the parking demand. So, it needs recon-sideration about the architectural regulations of parking supply.

In this study, for the capacity estimation of emergency electric generators built in apartment complex using NEGA C 201 method, it was proposed application methods of simultaneously starting groups and demand factors. Also, it was suggested that capacities of the electric generator might be calculated for two kinds of electric facilities; one is loads for the convenience of tenants when main electric supply cuts off, and the other is loads for fire. For 7 apartment complex of large-size (about 1, 500 households), medium- size (about 1, 000 households) and small - size (about 500 households), electric generator capacities were calculated and electric power were measured. Through the comparison between calculated values and measured values, it could be proved the suitability of these application methods. In addition, the calculated electric generator capacities were appeared to fit into engin capacities by NEGA C 201 method as well as those by conventional method.
