This study aims to analyze the field survey of thermal comfort in office building with national thermal environment standard. Internal and external temperatures were measured at ten minute intervals and compared in accordance with the national standard for thermal environment. Sixty two workers filled in the questionnaire survey forms five times a day for 40 days. Field monitoring of offices in Seoul, Korea were conducted from 20 July to 28 August. Result for the comfort temperature was set a $26.30^{\circ}C$. This indicates that the 26 degree is reliable for the Korean standard. Indoor temperature standard can reduce energy use by air-conditioned buildings and the temperature would be offer comfort to occupants.

This study performs analyzing a status of labor cost policy of public construction project and labor management information system in Korea for improving of labor cost survey in the construction market. The outcome of this study will be helpful to build a labor cost information system included the information of man-hour, regular pay and benefit, total wage. And if these result is integrated with the information of worker's career, qualification, skill level, it is confidently expected that the survey of labor cost is reliable.

The purpose of this study is to suggest the application method of CPTED for safer schools. For the evaluation of the school safety, we invented the school survey checklist based on the principles of CPTED such as natural surveillance, access control, maintenance, and activity support. The checklist is consisted of three parts of schools including boundary, outside of the building, and inside of the building. For the field survey of schools, the 30 schools(elementary, middle, and high school) were selected in Seoul and Kyong-gi area as the crime rate. The result of this study shows the safety score for the most of schools were not satisfied. In addition, we realized the diverse strategies to enhance the school safety should be applied to schools in terms of CPTED. The detailed findings and policy implications will be discussed in the context.

BIM (Building Information Model/Modeling) is attracting attention not only as a unit technology, but also as a factor that can promote the transformation of the entire construction industry process. This study aims to investigate the status and cases of policy introduction and legalization of BIM in foreign countries for the advancement of their own construction industry, and to discover policy implications that can be applied to Korea. The first survey uncovered policy elements, and based on this, the second survey conducted an in-depth survey of experts in actual BIM service and research activities. Looking at each priority, BIM standardization, mandating BIM in projects, payment standard establishment, and PQ additional points were given the highest level of importance.

After the outbreak of COVID-19, the construction industry, which has more contact between workers than other industries, needs to improve its environment through the technology development for automation of construction projects. This study conducted 5-point scale surveys of 39 candidate technologies on 54 workers in construction- related industries to derive priorities for technology development to improve the construction environment. The result of this survey shows the top 10 candidate technology priorities, and this analysis can be used as basic data for setting the direction for future construction development.

The purpose of this study is to analyze the window area ratio distribution of building facade in Tokyo metropolitan area. The survey was carried out in Marunouchi, Kanda, Kasai and Todoriki district. The results of this study were as follows; to propose of window area ratio production method, analyzed and surveyed window area ratio of each district building-used and to compared every wall window area ratio of building. Every wall window area ratio of office district is $20\sim40%$, ones of non-office district is 15% or 35%. Residential area results are every wall window area ratio of apartment is 35%, ones of a house is 15%. To increase of office building to appear that Kanda, Kasai added window area ratio. But, Marunouchi, Todoriki wad not this tendency. Above mentioned results are made out database.

Recently Korea has imported and executed Performance Based Design for the method to settle the dangerousness on outbreak of fire of high-rise building. The overseas country's PBD is autonomic but It is unable to carry out the essential role of PBD as the performance based design that based the code based design in the domestic. Also It occurs the problems that different the classification standard of building as dualisation between the building code and the fire services act. In this study, We have investigated overseas's cases for the PBD of high-rise building and have drawn the improvement direction & the problem of domestic's PBD by comparing and the analysing the domestic regulation.

Neglected buildings for long period can seriously reduce the durability of the building due to rust in rebars and deterioration in concrete quality due to exposure to outside air, and the seriousness of suspended buildings such as safety accidents and social crimes is emerging due to poor management. In this study, various problems such as the occurrence of safety accidents were analyzed through a fact-finding survey of buildings that have not been maintained due to long-term neglect in all areas of Jeju. In order to reuse a building that has been discontinued, the safety of the building structure itself must be checked. After securing safety through durability investigation, construction should be resumed or converted into a normal building through re-purposing, dismantling, remodeling, etc.

With the rise in the functions required in modern building structures, the role of the building equipment that maintains the functions of a building has been emphasized and increased. Effective management in this area is only possible when the construction manager (CMr) is qualified and has the knowledge of building equipment that is needed. Therefore, in this study, a questionnaire survey was carried out on equipment engineers and CMrs, in order to determine the level of building equipment knowledge required, and to identify the perception level of CMrs about the building equipment in the construction project at the project design stage. The results of this study revealed that the CMrs surveyed had a lower level of knowledge on the building equipment than the level that was desired by the equipment engineers. This indicates that CMrs currently have a weak capacity for the management of building equipment. It is thus necessary for CMrs to undergo systematic training in order learn more about building equipment and thus be able to manage construction projects more efficiently.

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.
