In order to plan and manage public facilities effectively and efficiently, it is necessary to diagnose the current status of facilities and decide the objective features. Performance measurement is to provide managers with the information they need to measure competitive advantages. This paper discusses public facility performance in order to establish the conceptual framework for performance measurement for public facilities. In order to develop the measurement of public facility performance, a pilot study was conducted with facilities managers of facilities management corporation of public districts in Seoul. We investigated how public facilities management teams have assessed their performance and collected data regarding financial aspects, service aspects, community aspects, and building aspects. There is no standard format to measure facility performance since building sizes, programs, community needs widely differ. However, it is necessary to have a more consistent system to measure facility performance. In addition, each public municipal district needs to empower each district facilities management corporation to participate in managerial decisions and budget control.

The purpose of this study is to prepare the introduction of the community facilities in public corporation buildings as the effort to community activation in the innovation city. The type and development condition of community facilities, and the cases of the private and public corporation buildings are studied. Moreover, the type and scale of facilities which can be established in the public corporation building that will move to the innovation city. The result can be summarized as follows; First, the community facilities can be classified into leisure, public administration, culture, athletics, and welfare, and the facilities are suggested at each hierarchy of living area. Secondly, the result of the case study shows that the public corporation establishes and operates various facilities include welfare, culture, and athletic facilities while the private part usually installs the cultural one. Thirdly, cultural(library, museum, performing place), athletic(soccer field, tennis court, swimming pool), welfare(day nursery, children's library) facilities are selected as the applicable ones to the public corporation building which is going to move to the innovation city. And finally, the basic unit of each facility is derived based on the investigation of legal standard, present condition, and literature reviews, etc., and applied to estimate the scale of the community facility in the public corporation building.

Recently, it is used to join an building to an underground shopping-area in urban. When we construct Seo-Cho Complex building which is in Seoul, we also construct an underground passage to the Gangnam underground shopping-area. But it is difficult to excavate in the downtown area, because excavations induce traffic jam and public discontent. Considering safety, a confined area, settlements, we decided to use DSM(Divided Shield Method) which is based on messer shield. This paper will produce our experience and the results provide a useful guide in a connection tunnel

This study has analyzed overseas projects of building rural communities using vacant houses. It is aimed at identifying the roles of NPO in the community-building projects and providing implications applicable to Korea. In recent years, there has been a spike in the number of vacant houses in rural areas. It is due to rapid urbanization and uneven distribution of the population across the country. Those are the reasons that prompted community-building projects. To solve the vacant house issue, there has been rising interest in building communities through vacant houses as rural resources and effectively integrating them as useful resources. However, the roles of key entity that pursues community-building projects using vacant houses have not been discussed sufficiently. Thus, this study deals with the 'Vacant House Recreation Project of NPO Corporation in Onomichi' in Hiroshima, Japan. Through the case study, the following are introduced as NPO's roles in community-building projects using vacant houses. First, pursuing promotion and attracting attention by making the utilization of vacant houses sensational; system improvement; offering information. Second, enhancing the perception of local residents by offering local services using vacant houses; offering community-building items. Third, forming a place of public discussion to solve conflicts during community-building projects using vacant houses; offering alternatives to building communities. Above all, such roles have led to the key status of NPO during its community-building projects using vacant houses. It offers the following implication for Korea: Future vacant house-related policies for rural revitalization should be done from community-building standpoint and include establishing the roles of NPO.

When managers estimate exact construction cost at early stage and design phase, they can reduce construction cost in a more efficient way than to predict at construction stage. But, the current of public construction cost estimation and management is concentrated almost after detailed design phase. Therefore, construction cost management in design development phase to generally use approximate estimating is not correct. Also, the existing construction cost used the method that estimated by gross floor area-based cost estimates at design development phase. So, it is difficult to show the specific amount of materials and basis about the estimated cost of the construction. This study derived problems and limits of construction management at design development phase in case of public office building project through review of literature and current survey, and suggested estimating process model process of structural construction cost go improve these matters.

The government has established a zero-energy roadmap in accordance with its 2050 carbon neutrality strategy, and from 2023 onwards, residential buildings with 30 generations or more must be constructed as zero-energy structures. In response to this, measures for energy conservation through enhanced building tightness are being developed. The LH (Land and Housing Corporation) aims to achieve the first-stage building tightness performance targets by 2022 in preparation for this. Currently, South Korea has the "KS L ISO9972 - Building Tightness - Measuring the airtightness of buildings by the fan pressurization method" as the method for measuring building tightness, which was established in 2006 and revised in 2016. In practice, the airtightness is measured using the Blower Door Test method, and it is expressed as ACH50 (the number of air changes per hour at a pressure difference of 50 Pa between the indoor and outdoor environments). This study aims to measure and analyze the airtightness of Happy Homes constructed from 2020 to 2022, categorized by building type.

This paper describes a design strategy at conceptual design stage using RETScreen software tool for building application of renewable energy resources. Currently, government and public buildings are required to adopt renewable energy systems with a minimum requirement for the amount of renewable energy supply. Meanwhile, there is a certificate program for private office buildings to enhance propagation of renewable energy systems. When considering application of renewable energy systems to a building, it is worthwhile developing a method to determine optimal design sizes of renewable energy systems. In the paper, a design strategy is introduced with a couple of case studies to determine optimal capacities of each renewable energy system in a building and suggest to use the method to evaluate the system for the building certificate program and the mandatory renewable target program. Objective functions considered in the study are initial system cost and reduction of CO2 emissions from the system. In the optimization study, it is assumed that solar thermal collectors are installed to satisfy solar fraction of 60%. Other renewable energy systems such as ground-source heat pump, solar PV and non-renewable systems such as electric chiller and gas-fired boiler are sized using an optimal sizing method with RETScreen suggested the authors previously.
