Computer simulation of buildings and solar energy systems is being used increasingly in energy assessments and design.. Building designers often now predict the performance of buildings simulation programmes that require hourly weather data. However, not all weather stations provide hourly data. Climate prediction models such as HadCM3 also provide the daily average dry bulb temperature as well as the maximum and minimum. Hourly temperature values are available for building thermal simulations that accounts for future changes to climate. In order to make full use of these predicted future weather data in building simulation programmes, algorithms for downscaling daily values to hourly values are required. This paper describes a more accurate method for generating hourly temperature values in the South Korea that uses all three temperature parameters from climate model. All methods were evaluated for accuracy and stability in terms of coefficient of determination and cumulative error. They were compared with hourly data collected in Seoul and Ulsan, South Korea.

The trend of Development Projects has been changing through a few recent years. Small-scale development projects in the past were usually for building residences or officetel in a big cities. making lots of profits. These projects made not only lots of profits but also unbalance between the urban centers and the suburbs. So government made some regulations to prevent the things from being worse anymore, planned to develop the country in balance and began to lead large-scale development project such as Inno city and Newtown. At first, in this study, the phases and the characteristics of development project's change will be looked around. And then, after overview about PFV(project financing vehicle) used a lot in large-scale development projects will be seen, the better ways to use PFV in large-scale development projects are going to be proposed by considering the problems in PFV's conformation.

The former administration office building of Kyeong-seong-bu(京城府) was a building converted from the Japanese residency-general's of Kyeong-seong(京城理事廳) which was originally built as the Japanese consulate in Joseon(日本領事館). It was too worn and too small as a Kyeong-seong-bu administration office even with several annexes. Kyeong-seong-bu tried to build a new big administration office building at the vacant north side of the same site, which was closely faced to the rotary in front of the Bank of Joseon(朝鮮銀行前廣場). But this trial was ended in vain due to insufficient budget. Therefore Kyeong-seong-bu built a new administration office building in another site and moved to it in 1926 with debts. For paying for the debts Kyeong-seong-bu sold the former site after partitioning with new roads through it. As a result the nature of the former site and its surroundings was changed. This study traces the changes and inquires how the authorities in the colonial Joseon and various commercial powers of Kyeong-seong-bu behaved for their own interests in the meantime. It makes use of the historical records and documentary literatures between early 1910s and early 1930s.

The law reflects the situation of the times, understands the society, and shows the will of the state and the community. The Means of Egress should be maintained from design to construction, supervision, as well as use, in order to protect the lives and property of the residents as well as the safe use of the facilities. However, Interior Architects are think that evacuation and safety regulations are complex elements that change frequently and may inhibit the idea of design. The purpose of this study is to propose a design method for the use of safe facilities in the interior architectural design on the evacuation regulations affecting the actual design by the IBC(the International Building Code) and NFPA(National Fire Protection Association) LSC (Life Safety Code). The research method is to investigate and analyze the provisions related to the evacuation of interior architecture in the US and to understand the current regulations and the evacuation regulations. We suggest to design method to the details of the hallway, corridors, aisle accessway, door way, exit path, In particular, the design of furniture, tables and chairs layout that could be obstacles to evacuation situations is presented.

In South Korea, there have been many studies on efficient building-energy management using renewable energy facilities in single zero-energy houses or buildings. However, such management was limited due to spatial and economic problems. To realize a smart zero-energy city, studying efficient energy integration for the entire city, not just for a single house or building, is necessary. Therefore, this study was conducted in the eco-friendly energy town of Chungbuk Innovation City. Chungbuk successfully realized energy independence by converging new and renewable energy facilities for the first time in South Korea. This study analyzes energy data collected from public buildings in that town every minute for a year. We propose a smart city building-energy management model based on the results that combine various renewable energy sources with grid power. Supervised learning can determine when it is best to sell surplus electricity, or unsupervised learning can be used if there is a particular pattern or rule for energy use. However, it is more appropriate to use reinforcement learning to maximize rewards in an environment with numerous variables that change every moment. Therefore, we propose a power distribution algorithm based on reinforcement learning that considers the sales of Energy Storage System power from surplus renewable energy. Finally, we confirm through economic analysis that a 10% saving is possible from this efficiency.
