Nowadays, many educational facilities are being renovated. However, due to the absence of a system for post renovation of educational spaces, users are less satisfied with the spaces after the renovation and there is a limit in establishing future directions for improving educational space renovation. From this point of view, this study was conducted to increase the users' satisfaction in renovation space planning of educational spaces and to establish a system for management after renovation. As a specific research method, the space preference of students was used to evaluate the space after renovation. By researching the opinions of the students who use the most educational space, not only the direction of the renovation plan of the future educational space can be given but also the user's opinion can be reflected in the spatial plan in detail. In terms of management of future educational spaces, this study can be used as a basic study for developing post evaluation indicators for renovation of educational facilities.

The purposes of this study were to make clear the present condition of the TVOC and HCHO concentration after renovation in apartment houses. The field measurements of TVOC and HCHO concentration according to the Korea Test Method Standard for Indoor Air Quality were carried out in 4 subject apartment houses. The results are as follows; the TVOC concentration after renovation in apartment houses ranged from mean 0.35ppm to mean 5.08ppm and increased of $0.35{\sim}5.08ppm$. The TVOC concentration of 3 subjects exceeded the Indoor Air Quality Management standard for the newly-built apartment houses (0.58ppm). The HCHO concentration after renovation ranged from mean 0.13ppm to mean 0.43ppm and increased of $0.06{\sim}0.26ppm$. The HCHO concentration of 2 subjects exceeded the Standard (0.17ppm). As results of analysis on the relation of concentrated ascension and renovation elements, the amount and the types of finishing materials and adhesives affected concentrated ascension. Also, production method for installed or purchased furniture had certain effect on the TVOC and HCHO concentration ascension.

Residential building owners are turning toward renovating their existing buildings to improve old and inefficient HVAC systems. Due to the renovation, much of the added costs will inevitably be passed on to tenants by increasing rent rates. This increment often increases the vacancy rate in the buildings. To balance the interests of both owners and tenants, this paper suggested a method to determine an appropriate rental rate increment for the HVAC system renovation. A case study on residential buildings was conducted to determine a balanced point where the rental rate increment that offsets the amount tenants are willing to pay for the renovation. To calculate all costs incurred by the renovation, life-cycle cost analysis was carried out. Therefore, this paper ultimately provides a threshold value of rental rate increment such that building owners can make a reasonable decision on the HVAC system renovation.

The Cadastral Renovation is a National project to investigate and survey the registration of Cadastral Record and replace the existing Cadastral Record with a new Cadastral Record by digital, and to correct the registration of Cadastral Record if the registration of Cadastral Record does not match the actual status of the land. The Business Period generally takes about one year and six months to two years. The time required is getting longer due to problems that occur in the course of the Adjustment amount after the cadastral resurvey survey due to complex structure and internal conflict due to the interest between landowners. After Boundary Decision of the real boundary, the land area is confirmed by the landowners, and the cadastral office is to settle the Cadastral Renovation by calculating the Adjustment amount according to the confirmed area and the increase and decrease of the cadastral area. Therefore, the solution plan was suggested so that reasonable Adjustment amount can be applied through empirical research applied to the time of calculation of Adjustment amount and the method of calculation of Adjustment amount. The improvement method showed the expected effect that can lead the agreement with the landowner to the shortest period, and it was also possible to set the real boundary that meets the purpose of the Cadastral Renovation. This study suggests improvements in the method of calculating standard Adjustment amount, the method of imposing Adjustment amount, and the method of boundary adjustment that does not impose adjustment amount through the cadastral Renovation and parallel studies, and it is expected that the Cadastral Renovation will be completed by 2030.

The aims of this study is to analyze that the double-skinned outer surface of building will be the effective measure to improve the use of space and save energy through the evaluation of the buildings renovation. In other words, it is significantly effective to increase the insulation of the outer surface where the most heat loss occurs; it is also energy-saving to convert the space created by pilotis in the southern and northern parts of the buildings into an double-skinned atrium. Research methods of this study are consisted with two steps, situation analysis and simulation analysis. IRISYS 1000 Series Imager was used for research of situation analysis and Visual DOE 4.0 was used for simulation analysis with the 1st Buildings of Jeju Special self-Governing Province. As results of simulation, it was proved that Double skin Method is more effective for green building than basic model. it was predicted to save 8.6% of energy by Double skin Method. Especially, in case of using of ventilation within double-skinned atrium, it was predicted that saving of energy was most effective than other method.

Background: The advanced spent fuel conditioning process facility (ACPF) of the irradiated materials examination facility (IMEF) at the Korea Atomic Energy Research Institute (KAERI) has been renovated to implement a lab scale electrolytic reduction process for pyroprocessing. The interior and exterior structures of the ACPF hot cell have been modified under the current renovation project for the experimentation of the electrolytic reduction process using spent nuclear fuel. The most important aspect of this renovation was the installation of the argon compartment within the hot cell. Method: For the design and system implementation of the argon compartment system, a full-scale mock-up test and a three-dimensional (3D) simulation test were conducted in advance. The remodeling and repairing of the process cell (M8a), the maintenance cell (M8b), the isolation room, and their utilities were also planned through this simulation to accommodate the designed argon compartment system. Results and conclusion: Based on the considered refurbishment workflow, previous equipment in the M8 cell, including vessels and pipes, were removed and disposed of successfully after a zoning smear survey and decontamination, and new equipment with advanced functions and specifications were installed in the hot cell. Finally, the operating area and isolation room were also refurbished to meet the requirements of the improved hot cell facility.

The grands ensembles, or large-scale high-rise housing projects, are widely regarded as notorious products of postwar French government policy in the area of housing and urban planning. There was a general consensus that the grands ensembles had been a 'failure'. They were perceived as the source of all the ills of the contemporary city, as responsible for a social breakdown stemming from lack of infrastructure, geographical isolation, and monotonous environments. French government embarked on a broad renovation effort in light of the deteriorated condition of grands ensembles in the 1980s, which has been approved as generally 'successful'. This study focusing on French cases allowed me to demonstrate that following qualifications are critically important for successful housing projects: urban contextual continuity, socially mixed community, authentic planning for achieving sense of place, relationship between collective and individual expression, et cetera.
