The purpose of this study is to investigate that which Goon office buildings were reused from existing buildings and to identify remodeling and extension ways of the reused to match Goon's administration work. This study used literature research method, i.e., analysing the digital images, the annotation, and the official documents between the Japanese government-general of Korea and To(道), and articles of newspapers and journals. The reused were governmental offices of Joseon(朝鮮) dynasty, existing Goon office buildings of Korean empire government and old buildings with unknown purposes. They were remodelled and extended to match Goon's administration work. Common remodelling was making large space with desks for civil petitions and projecting an small entrance from the center of main building's facade. Common extension was constructing accessory buildings with simple wooden structure, locating them to back or side of the reused, and connecting them through external corridor. As many as 30% of 218 Goon office buildings were reused. About 57% of them were replaced as new office buildings, however the number of the new was rapidly decreased after mid 1930s.

Despite the changes to demands and perceptions according to building deterioration, most of the previous studies on remodeling have focused on apartment buildings, which are residential buildings. Few studies have been conducted on buildings for general commercial use, or office buildings. Accordingly, this study set out to prepare a set of performance criteria to assess the remodeling feasibility of office buildings. For that purpose, 23 assessment items were devised, their importance was tested, 13 were extracted, and a set of scoring criteria for each item was prepared. Case analysis was conducted to check the reliability of the assessment items and scoring criteria. Through this analysis, it was found that the criteria were reliable.

The purpose of this study is is to organize the site-plan types of common design's Goon office buildings in Japanese colonial period based on the main building's shape and main & attached building connection way and to investigate all the types' addition & remodeling ways. The study used literature research method, analysing the digital images, the annotation of the images, official documents between the Japanese government-general of Korea and To, and articles of newspapers or journals. The site-plans are sorted 5 types and subdivided 13 as their addition & remodelling ways. The initial shapes of site-plan were changed to apply every Goon's site circumstances, The main buildings were always in the center ahead and attached buildings behind or next to them in any cases of new construction, addition or remodeling. The buildings of the common design's were constructed until early 1930s and it means that their architectural level was lower than Pu office buildings, although both had same administrational level.

There are lots of buildings which were built before the Legislation on building energy rating system. Remodeling of the buildings would be required for an improvement of the building energy rating system was enforced by the government. In the Passive Building Design, Elements which will be used for the remodeling are Insulation, Window, External venetian blind, Heat exchanger. The Purpose of this study is to indicate a Method for the improvement of Energy saving by an analysis of Construction Cost, Cost Evaluation, Energy performance Efficiency in applied design elements. In this study, the remodeling of existing public buildings to improve energy efficiency rating was applied to extract the elements of design-specific energy performance, efficiency, and the application of the designs that has been analyzed. The results were as follows: applying the design-specific cost-effective investment that represents the economy (investment efficiency/%) surveyed the average insulation(7.0%), triple glazed windows(10.1%), double glazed windows(12.1%), external shading(24.5%), and Heat(77.2%) were analyzed in order to be more efficient. Analysis of the basis of information on the existing public buildings to improve energy efficiency rating for the remodeling depending on driving conditions at a degree of individual difference. The main effect, however, depending on economic investment, design elements, heat exchangers, external awning, double glazed windows, triple glazed windows, insulation, is recommended as review of the order shall be determined.

This study is to analyze the remodeling method of library in terms of space extension method and urban regeneration by repurposing function in unused facilities through case study. In many case of library extension, horizontal extensions are more frequent than vertical extensions, because there are limits to extend vertically due to high live load estimation by book stacks. Extension schemes was organized by new building extension method in connection with existing buildings, attaching method small scaled mass or linear mass to existing building, connecting method a plurality of existing small buildings, vertical extension method on the top of the structure, underground extension method using special structure. Unused facility remodeling to the library, large scaled buildings can be developed completely to the function of the library through the relocation of the space, while small scaled building needs spatial extension. In the case of spatial extension, existing space that was used for other purposes can be used as a reading room or office, avoiding high live load estimation.

Due to a waste of energy in korea, about 525,000 which are 75 percent of total buildings are at least 15 years old buildings that need remodeling. There are two current remodeling systems. One is a remodeling system to reduce a waste of resources from the reconstruction. The other is a green-remodeling system aimed to energy savings and reducing environmental costs. This study is to analyze quantitatively these current systems with respect to the cost-benefit caused by the life cycle and suggests the political and institutional implications through the interpretation of the results. For a quantitative analysis, we analyzed reducing maintenance costs and rent benefits with simulation by using opportunity costs, construction costs, plan costs and supervision costs as expense variables and using the reduced floor area ratio, institutional incentives, energy, water resources and certified emission reduction(CER) as benefit variables. As a result of the empirical study, the green-modeling was more beneficial in the field of environment such as the energy savings, however, the final benefits of remodeling which has no green building certification costs but more floor area ratio incentives were more economical. The green-remodeling system focused on reducing environmental costs and energy savings needs a equatable institutional incentive system.

Recently, there have been a large number of remodeling (or renovation) works in old buildings in urban areas. Compared to new buildings, environmental risk might be more significant in such buildings where remodeling works are going on, since some parts of the building may still be in service for people. This study was carried out to investigate the impacts of remodeling works on the indoor air quality (IAQ) of a large building (a 22 stories university library). Indoor air monitoring was conducted during and after the remodeling works every two weeks for a one year period, and target compounds included BTEX, styrene, TVOC, carbonyl compounds such as formaldehyde and acetaldehyde. $CO,\;CO_2,\;PM_{10}$, and $PM_{2.5}$. Overall, the IAQ appeared to be recovered within two months after the remodeling works. However, in some places, concentrations of formaldehyde, toluene, xylene. and ethylbenzene showed higher levels even after works than those during the works. The results indicate that painting, glues and office furnitures are major sources of aromatic VOCs and formaldehyde. Therefore, in order to decrease the concentrations of toxic VOCs, the use of environmental-friendly building materials is strongly recommended during the remodeling works. In addition, IAQ control and management scheme (for example, baking the inside of the building) should be taken into consideration before reopening the buildings.

The Korean government has introduced building regulations with improved energy conservation measures, including higher insulation levels for building envelope. However, there are many existing buildings that tend to consume more energy for heating and cooling than new buildings, as they were built under the former regulations with relatively higher U-values of walls and glazing. In order to improve energy efficiency in existing buildings, green remodelling of building envelope and building services are required. For existing buildings, building services improvements have been achieved through energy service company(ESCO), but much attention has not been paid to building envelope improvements with various reasons, such as uncertainty of energy saving effect design issues and costs. The aim of this study is to evaluate the impact of building envelope improvements in a typical commercial building on its heating and cooling energy loads. The results show that the improvement of glazing with lower U-values has the highest energy saving effects, followed by wall, roof and floor, under the condition of same level of insulation improvements. However, high insulated glazing increased LCC because of higher initial investment costs.

Remodeling for an aged building is emerging as a potential alternative towards the future of the building industry. It is a more effective method than the new construction in environmental friendly view. Most of remodeling were aimed at the improvement of the function of the deteriorated finishing materials. But, at the early stage of remodeling process, energy performance of a building can be improved by adopting passive design solutions such as daylighting and natural ventilation. The purpose of this study is to explain the passive design strategy in remodeling process and to suggest a application of LT method. LT method is an energy-design tool which responds to parameters available early in design development. It provides an output of annual primary energy for lighting, heating, cooling and ventilation in non-domestic buildings. LT method basically uses the concept of passive zone and non-passive zones and should be used to evaluate the energy performance of a number of options and to make comparisons. In this paper, the process of LT method is introduced and investigated an applicability in our office building.
