In this study, we looked into the method to establish fire growth rate by buildings use for growing fire at the beginning of a fire considering the characteristics of the combustibles in a performance-based design. Actual conditions survey and literature review were carried out for the fire load and exposed surface area of combustibles to establish design fire by domestic building use. As a results, a simplified prediction equation of fire growth rate which depends on fire load and weight of combustibles could be derived by calculating the relation between the fire load and the fire growth rate of an initial fire through investigation of combustibles by domestic building use.Also, as a result of analyzing the placement of combustibles and location of the ignition source, it was found that the influence of the materials of the combustibles and the materials of the combustibles adjacent to the ignition source is big. Though 4 different experiments were carried out for the evaluation, the result of comparing the findings with those of FGR model showed that the fire growth rate was similarly derived.

The city means not only a geographical area as a role of the spatial boundary, but also a socio-economic place to communicate with each area. It requires various functions to get the income and economic-activities. But city has a limitation of a available land to provide the required functions and a sufficient space to supply the urban activity. Therefore, the development trend of city has not been to spread to the horizontal area any more and considered the vertical area. In addition, various functions put into a massive building because many people want to solve the daily requirements without spending time and cost in outer area. In this paper, it aimed at classifying the mixed-use building into function, circulation, relation according to the public and private space and the building shape to provide the design information such as land area, functional complex, accessibility, etc.. The classification of the mixed-use buildings is divided into four areas. The data are collected with foreign countries in Japan, Europe and US. Results of the study are as follows; First, the commercial function is mainly centered with other functions. Second, after studied the development scale, accessibility, building form, the commercial and residential area overwhelmly share at the total area.

In response to the rapid climate change, in order to save energy in the field of buildings, the country is planning not only zero energy buildings but also zero energy cities. In the Urban Development Project, the Energy Use Plan Report is prepared and submitted by predicting the amount of energy demand at the planning stage. However, due to the activation of zero-energy buildings and the increase in the supply of new and renewable energy facilities, the energy consumption behavior of buildings in the city is changing from the previous ones. In this study, to estimate urban energy demand of Zero Energy City, building energy demand forecasts based on "Passive plans for use of energy based primary energy consumption", "Actual building energy usage data from Korea Appraisal Board" and "data from Certification of Building Energy Efficiency Rating" as well as demand forecast according to existing "Consultation about Energy Use Plan Code" were calculated and then applied to Multifunctional Administrative City 5-1 zone to compare urban total energy demand forecasts.

건물의 에너지사용량을 효율적으로 관리하기 위해서는 에너지의 사용에 대한 모니터링이 우선시 되어야 한다. 건물에서의 에너지사용량은 크게 에너지원별, 용도별, 구역별로 구분하여 관리할 수 있다. 에너지원별이란 건물의 설비를 가동하기 위해 공급되는 전기, 가스, 연료, 지역난방 등을 의미한다. 용도별이란 크게 냉방, 난방, 조명, 급탕, 환기와 같이 5대 용도로 구분할 수 있지만, 5대 용도 안에 포함시키기 어려운 엘리베이터나 전열기기 등은 별로도 분류하는 것을 의미한다. 이 외 구역별은 건물의 사용목적이나 사용용도가 비슷하거나 구분되는 지역을 묶어서 비교 관리 하거나 별도 관리 하는 것을 말한다. 이 밖에 에너지의 효율관리에서는 건물의 에너지사용량에 영향을 주는 온도, 습도와 재실자에 대한 관리가 필요하며, 최근 문제가 되는 미세먼지는 건물의 환기에 직접적인 영향을 주기 때문에 이에 대한 관리도 병행되어야 한다.

Building structures generally have inherent low damping capability and hence are vulnerable to seismic excitations. Control devices therefore play a useful role in providing safety to building structures subject to seismic events. In recent years semi-active dampers have gained considerable attention as structural control devices in the building construction industry. Magneto-rheological (MR) damper, a type of semi-active damper has proven to be effective in seismic mitigation of building structures. MR dampers contain a controllable MR fluid whose rheological properties vary rapidly with the applied magnetic field. Although some research has been carried out on the use of MR dampers in building structures, optimal design of MR damper and combined use of MR and passive dampers for real scale buildings has hardly been investigated. This paper investigates the use of MR dampers and incorporating MR-passive damper combinations in building structures in order to achieve acceptable levels of seismic performance. In order to do so, it first develops the MR damper model by integrating control algorithms commonly used in MR damper modelling. The developed MR damper is then integrated in to the seismically excited structure as a time domain function. Linear and nonlinear structure models are evaluated in real time scenarios. Analyses are conducted to investigate the influence of location and number of devices on the seismic performance of the building structure. The findings of this paper provide information towards the design and construction of earthquake safe buildings with optimally employed MR dampers and MR-passive damper combinations.

오늘날 지목은 토지의 이용용도나 이용형태를 결정짓는 가장 구체적인 법률적 기준이 되고 있다. 지목은 토지의 주된 사용용도에 따라 분류되기 때문에 주 사용용도가 동일하다면 모두 같은 지목으로 결정하고 있다. 동일한 "대" 지목이라 하더라도 구체적으로는 단독주택, 연립주택, 다세대주택, 빌라, 아파트, 주상복합, 상업 업무용, 나대지 등으로 다양하게 이용되고 있어 그 명확한 구분이나 분류기준 등에 있어 한계성을 가지고 있으며 녹색성장을 위한 온실가스 배출실태나 감축 또는 통계산정에 있어서 용도별 배출특성을 다양하게 분석 할 필요성이 제기되고 있다. 그래서 본 연구는 기관별 다른 분류체계를 가진 5개의 도면을 중심으로 이산화탄소 배출량을 실제로 측정하여 분석한 결과 계절별은 겨울, 봄, 가을, 여름순으로 측정 되었으며, 겨울과 여름의 가장 큰 분포특성은 1.78배, 평균 1.35배가 높게 나타났으며, 오전 9시와 15시의 기온이 약 $11^{\circ}C$ 변화할 때 22ppm으로 오후가 높게 측정되었다 용도별로 분석한 결과 단독주택에 비해 상업 업무용은 4.04배, 주상복합은 1.47배나 높게 배출되었다.

This study aims to analyze how the color of Korean traditional architecture affects its plasticity. The researcher took (our distant and near photographs of each representative building of each use, measured the colors, and analyzed these using the color perception theory. The results are summarized as follows: 1. When perceiving the entire plasticity of a building, the color of Korean traditional architecture reduces the heavy feeling that may be brought about by the roof's weight, but stresses the solidity of the pillars. This color perception effect displays the visual stability and balanced plastic beauty of the building's facade. 2. When looking at a building up close, the building's color emphasizes the solidity of the major materials used to construct it through a contrast effect, and highlights the characteristics of each building, such as the dignity of its seal engraving, its magnificence, its simplicity, etc. 3. The color of Korean traditional architecture is a major factor that expresses plastic language as it displays topographical level differences and intercepts or opens view through the artificial division of space, etc., according to the building's use.
