Building Equipment field is getting important recently which satisfies the requirement for pleasant living environment. But, the noise generated in the machinery room often violates the pleasant living environment of residents in complicated form of airborne noise and soild sound, its seriousness is increasing so that damage of noise can take large percentage of environmental complaints. So, soundproofing and insulation of sound which can minimize such noise and effective countermeasure in case of civil appeal are required, but research materials regarding building equipment are definitely insufficient domestically. In this respect, this study used Zwicker parameter which is applied by psychological and acoustic reactions according to sound quality, analyzed sound quality of 32 kinds of building equipment used in machine room, and analyzed correlation between dB(A) and PSIL which are items of Zwicker parameter and noise valuation based on that. As the results, if valuates altogether loudness and unbiased annoyance which have high correlation with other existing suggested valuating methods, it is considered that it can be utilized as basic data for more reasonable and accurate grasping characteristics of noise from building equipment and for building effective countermeasure in case of civil appeal.

Recently, advanced metering infrastructure (AMI) has been recognized as a core technology of smart water grid, and the relevant market is growing constantly. In this study, we developed all-in-one smart water meter of the AMI system, which was installed on the test-bed to verify both effectiveness and field applicability in office building water usage. Developed 15 mm-diameter smart water meter is a magneto-resistive digital meter, and measures flow rate and water quality parameters (temperature, conductivity) simultaneously. As a result of the water usage analysis by installing six smart water meters on various purposes in office building water usage, the water usage in shower room showed the highest values as the 1,870 L/day and 26.6 liter per capita day (LPCD). But, the water usage in laboratory was irregular, depending on the many variables. From the analysis of the water usage based on day of the week, the water usage on Monday showed the highest value, and tended to decrease toward the weekend. According to the PCA results and multivariate statistical approaches, the shower room (Group 3) and 2 floor man’s restroom sink (Group 1-3) have been classified as a separate group, and the others did not show a significant difference in both water use and water quality aspects. From the analysis of water usage measured in this study, the leak or water quality accident did not occur. Consequently, all-in-one smart water meter developed in this study can measure flow rate and water quality parameters (temperature, conductivity) simultaneously with effective field applicability in office building water usage.

본 연구의 목적은 초고층 주상복합건물의 품질관리를 통한 시공 분야의 효율성의 특성을 파악하는데 있다. 기존연구에서 시공관련 품질개선요소들이 정리되었으며 규격화된 설문서를 통하여 시공 분야에 있어서 개선요소를 대학원생을 포함한 건축 관련 대학교, 건설회사, 설계사무소등의 실무자들의 의견을 조합하였다. 설문조사 결과와 기존현장 기술자들의 품질관리 인식도를 비교하여 현장별 품질관리의 정량적, 정성적 성과척도를 파악하고 분석하였다.

본 연구의 목적은 한국건축프로젝트의 경영적 특성을 파악하는데 있다. 본문은 건축프로젝트의 주요 세 요소인 디자인, 건설, 유지관리의 프로세스 질 관리에 영향을 미치는 요소들을 조사한다. 설문조사는 건축관련 대학원생 및 교수, 설계자, 시공자들의 건축프로젝트에 있어서 프로세스 질 관리에 대한 상이한 시각을 보여주고 있다. 이러한 요소들을 분석함으로써 현재 국내의 질 관리 시스템과 프로그램 내용을 교정하고 개선하는데 도움이 될 것이다. 프로세스 질 관리에 있어서 여러 요소 중 설계자와의 협조가 가장 주요 요소로써 부각되었다.
