To provide pleasant building environment and the ease of maintenance and facility management, many new office buildings are being built as intelligent buildings. Building control systems which are employed in intelligent buildings require advanced types of controllers and varieties of control schemes. Designing and installation of these types of advanced building control systems take a lot of effort and also they are costly. In order to design these systems, it is necessary for the designers to have means to analyze and estimate the performance of control systems. The simulator which is presented in this paper is composed of three parts, HVAC simulation module, elevator simulation module, and evacuation modeling module for the outbreak of fire or similar disasters. In this paper, the functions and modelling method for each module are explained and simulation results are presented.

As Building Integrated Photovoltaic(BIPV) system replaces the conventional building finishing materials with PV modules, two function of electricity generation and building envelope can be expected. Therefore BIPV can be a good alternative technology for the 21 century environment-friendly buildings. The objective of this paper is to develope BIPV modules for a commercial buildings of which structure is mainly light-weight, curtain wall system. Two types of module are developed for a opaque part and a transparent part of building envelope. Current technology level and market status of Korea determines the configuration of developed BIPV modules. Architectural considerations for the integration of PV module to building envelope such as building structure, construction type, safety, regulation, maintenance etc. have been carefully reflected from the early stage of BIPV module design. Especially the survey result of current building envelope materials determines the size of unit BIPV modules and a unique cladding method for PV module installation is developed. Trial product of BIPV modules and cladding hardwares are manufactured and sample construction details for a demonstration building are proposed.

In Korea, Housing Performance Rating Indication System was first adopted in 2006. Main purpose of the System is on developing criteria which can systematically measure the level of housing performance. Among the five categories of Housing Performance Rating Indication System, Repair Convenience is closely related to Remodeling which has been widely recognized as an alternative to the building reconstruction. Especially, as the actual housing supply level in Korea is reaching almost 100%, it is crucial to expand Long-life Housing through the effective maintenance and management. In addition, consumers should have an access to the performance ratings of apartment buildings on which they can rely on in choosing their own housings. And for construction companies, a performance code enacted by government will provide them with a standard that they can utilize in determining performance level of buildings that they build. This study examines data which has been obtained from the recent application of Housing Performance Rating Indication System and Repair Convenience category is main concern. Findings from the study will provide vital information in improving current Housing Performance Rating Indication System.

This research is carried out to inspect the Apartment Management System of Japan, to examine the similarities and differences between the Korean Apartment Management System and the Japanese Apartment Management System. First, as the basis law of apartment management, there exists the Building Unit Ownership Act, the Promotion Law fur Adequate Mansion Management of Japan, the Housing Law, Housing Execution Law and Rule of Korea. Second, the Association of Apartment Owners, an organization of owners of apartments in Japan and the Commission of the Representatives of the Occupants in Korea become the subject of maintenance. The Japan structure is made of the Assembly, the Director and the President. The Korean structure is made of Regular and Temporary Conferences and elected Officers(1 president, at least 2 directors and at least 1 inspector). The Commission of the Representatives of the Occupants and the Organization of Owners of Apartments make bylaws and diverse maintenance rules. Third, the foremost reason why the Korean structure of maintenance of apartments is less efficient than Japan is because of the small number of people dispatched to the living-environment maintenance team and their short terms. It is necessary to grow professionals related to this sector and to have enough public servants that specialize in this. Fourth, although it is compulsory to make long term plans for maintenance based on the Housing Law, because the reserve fund is decided by the maintenance rule(with no compulsory standards of reservation) of each apartment, it is difficult to reserve an adequate amount of reserve fund. So as in the example of the state of Hawaii in America, based on long term plans for maintenance, an execution rule of the Housing Law should be made which enforces to reserve at least 50 percent of future maintenance expenses.

In this study, we investigated a life cycle assessment (LCA) of six roof-waterproofing systems [asphalt (C1), synthetic polymer-based sheet (C2), improved asphalt (C3), liquid applied membrane (C4), Metal sheet with asphalt sheet (N1), and liquid applied membrane with asphalt sheet (N2)]for reinforced concrete building using an architectural model. To acquire accurate and realistic LCA results, minimum units of material compositions for life cycle inventory and real data for compositions of waterproofing materials were used. Considering only materials and energy demands for waterproofing systems per square meter, higher greenhouse gas (GHG) emissions could be generated in the order of C1 > N2 > C4 > N1 > C2 > C3 during construction phase. However, the order was changed to C1 > C4 > C3 > N2 > N1 > C2, when the actual architecture model was applied to the roof based on each specifications. When an entire life cycle including construction, maintenance, and deconstruction were considered, the amount of GHG emission was in the order of C4 > C1 > C3 > N2 > C2 > N1. Consequently, N1 was the most environmental-friendly waterproofing system producing the lowest GHG emission. GHG emissions from maintenance phase accounted for 71.4%~78.3% among whole life cycle.
