It is difficult to check the exact building energy consumption reduction such as when green remodeling of buildings, because it is due to outdoor air temperature over the years. And in Korea although Big Data of building energy consumption is collected and managed through "The Information System of the Building Energy and Greenhouse Gases" it is underutilized because of non calibration of outdoor air temperature change. Therefore, this study aims to develope calibration method of building energy consumption by outdoor air temperature according to micro climates, and building use types. As a result of analysis, Regression equations of Building energy consumption and $HDD_m/CDD_m$ are derived and calibration method is developed by Regression coefficient.

If we build new building after demolition of commercial building that is located in the downtown, it will be caused a social and environmental problem as wasting of resources and generating of waste. In this study, I investigated about remodel ins, this conclusion is given below. 1. Reconstruction cost is 2.1 times, and construction period is 1.4 times as much remodeling. So remodeling has an advantage. 2. For repairing and reinforcing timeworn building, we reinforced it as using carbon fiber sheet (girder, slab) and injecting method steel plate bonding Also, we tried to maintain efficiency of new building as using epoxy to protect concrete crack. 3. In the side of waste products and cost, remodeling has much more advantage than reconstruct. But demolition used construction period much. Because it had to be reused as repairing and reinforcing. And there was no difference between remodeling cost and reconstruct cost. If we develop research with enterprise.university.laboratory to exploit material and equipment and to train specialized engineer who will has a capacity to know construct repair and reinforce, it can be attribute to prevail remodeling in new construct market.

It is essential to know climatic characteristics of the site for energy efficient building design. However, it is difficult to obtain a climate data. Even though the climate data is obtained, it is difficult to be applied to the building design since it is usually consisted of just series of numbers. Also, designers cannot know the effective climatic design strategies suitable for the site with ease. Thus, this study aims to develope the climatic design tool working on the personal computer operated by windows 95/98/2000/XP. WYEC weather data and building bioclimatic chart are adopted for the climate analysis. Climatic Characteristics(distributions of the dominant factors, bioclimatic needs, needs to each passive design strategy, and the order of priority, etc.) of Seoul are analysed and presented as an example. Also, passive climatic design process making use of this tool is presented.

Incheon City move onward re-modeling about Jayu Park(public park) in Incheon city. The building restoration must equip all data which are necessary to a restoration and it must be advanced and, currently the project which is advanced is not like that. The place objective which evaluates the restoration possibility of the modern time building where this dissertation is included consequently in project contents it is letting. The evaluation result data is not secured not to be, the restoration is impossible. Also simplicity reappearance of the building where the function disappears without being true feelings characteristic is there is not a possibility of having a construction value. The modern time building restoration which Incheon City it propels consequently it is right to be discontinued.

In this study the relative effects among trees, cars, wires and building facades on visual preference are measured with the photo-montage scenes, which were synthesized by computer graphic programs. In addition to these experiments, the interaction of each elements of streetscapes have been investigated. The results of this study can be summarized as follows ; (1) It was found that trees had a remarkable positive effect on preference for streetscapes, wires had a moderate negative effect, cars had a trivial effect and the effects of building facades were medium. (2) It was investigated that the building of residential type was most preferred among commercial, residential, and office building types. The next preferred building facade was the commercial type. (3) The interaction of each element of streetscapes also have effects on preference. Especially, it was found that the combined effects of building-wire and building-cars were more notable than other combined effects of two elements.

Since artificial building materials and environmental contamination are getting worse recently, people has been interested in eco-friendly construction. In addition, the problems like Sick Building Syndrome are issued these days. In order to solve these problems, the reuse of building materials and the development of environment-friendly materials are urgently in demand. In this sense, Hwangtoh is in the limelight as the environment-friendly material, and broad studies on it have been in progress. However the reactivity of Hwangtoh is low, and without activation process it is very hard to use it as a building material. This study examined the usability of Hwangtoh as an environmental building material by experimenting the reactivity of inactivated Hwangtoh with Reaction Induction Material.

In Korea, in the case of fire scenarios in performance design, it is assumed that the sprinkler is not working. In addition, it does not applicate various fire conditions. Therefore it is not enough that the accuracy about fire scenario. In foreign countries, reseach is being conducted to predict the casualities that can occur due to fire in the building space through statistical risk analysis. Also, research is consistently conducting for design that consider the sprinker probability of operation. Therefore, to analyze the fire risk of each building in Korea, the risk was analyzed using statistical data. As a result, the risk of casualties that can occur for each building use was analyzed as 0.6(persons/cases) for residential buildings, 0.25(persons/cases) for sales facilities, and 0.12(persons/cases) for buisiness facilities.

Recently as construction projects have been complicated, it has been wearing thin to draw on their personal experiences for management. Although the advance of IT, using the technology for construction is insufficient in contrast to other industries. BIM has been steadily used in construction projects, but it is not easy to find the case of successful use. This research considers ways in which BIM technology can be applied to useful management on a construction site and derives a method of application of using BIM for a Mega-complex Building Project especially.

Purpose: The purpose of this study is to present basic data which would be applied on the early stage of the architectural design. And that determines the introduction of the atrium by comparing and analysing the environmental performance of atrium building. Method: The building forms are classified into low storied building, middle storied building and high storied building. This study compares and analyses energy performance of the standard building without atrium and the atrium building which has one-side, two-side, three-side, four-side, and linear atrium by measuring of annual heating and cooling load with EnergyPlus. Result: As a result of the analysis of the relative annual heating and cooling load by building type, it is shown that the fluctuation of cooling load in low storied building is large because heat storage in atrium affects building, and the fluctuation of heating load in high storied building is large owing to the effect of external wall area of atrium which makes heat loss. Especially, it indicated the largest annual heating and cooling load in four-side atrium of low storied building, and in one-side atrium of high storied building.

Nuclear containment building is used as second blockage to protect us from a radiation leakage caused by the natural disaster or any accidents, so it's safety is important and must be kept with continuous surveillance. In this study, we measured the strain of a nuclear containment building's wall by using FBG sensor and investigated the structural safety of a nuclear containment building. 50 FBG strain sensors and 18 FBG strain sensors were attached on the side wall and upper dome of a nuclear containment building, respectively. We measured the strains of the outside concrete wall during the Structural Integrity Test (SIT) of a nuclear containment building. The strain of an upper dome was larger than that of a side wall, about $200{\mu}{\varepsilon}$. And the very small strain was measured at vertical direction of a side wall. These experimental results were used to evaluate the structural health of nuclear containment building.
