양은지,김개천 한국문화공간건축학회 2015 한국문화공간건축학회논문집 Vol.- No.49
The environmental and energy issues are requiring various measures to respond beyond the level of resource andenergy conservation, making continuous developments and attempts of diverse concepts of architecture. However, this researchwas conducted based on the fact that there are lacking researches on the issues caused by the confusion of concept anddesign directions and design approaches. This study reviewed the expression characteristics of spaces by concluding the characteristics of plus energy with domestic andinternational examples based on the summarized concepts and elements of plus energy. Plus energy houses reduce energy, maximize energy efficiency and generate energy by transforming the innovativetechnologies-introduced natural elements into energy. Through the characteristics factors of ‘Energy Plus, Eco Plus, Emotion Plus’, plus energy makes harmony with technology,nature and emotion rather than maximizing energy with just natural elements and technological formats. Plus energy houses allow the architecture itself to create the nature and pleasant and healthy space. “Plus Energy House” can effectively control and reproduce the use of energy depending on the technological introductionmethod and give values as a resource. Plus energy architecture absorbs the energy of the spaces in different forms andchanges itself to adapt to the environment in a flexible way. Plus energy puts first the nature and human life through thebalance between nature, human and architecture, and transforms itself to the new forms of energy.

South Korea aims to shift the 20 percent of electricity supplement from the fossil fuel including the nuclear to renewable energy systems by 2030. In order to realize this agenda in the buildings, the plus energy house is necessary to increase the renewable energy supplement beyond the zero energy house. This paper suggested KePSH (KIER Energy-Plus Solar House) and energy performance of house and renewable energy systems was investigated. The KePSH has the target of generating 40% surplus energy than the conventional house energy consumption. The plus energy house is the house that generates surplus energy from the renewable energy sources than that consumes. In order to minimize the cooling and heating load of the house, the shape design and passive parameters design were conducted. Based on the experimental data of the plug load in the typical house, the total energy consumption of the house was estimated. This paper also suggested renewable energy sources integrated HVAC system using air-source heat pump system. Two cases of renewable energy system integration methods were suggested, and energy performance of the cases was investigated using TRNSYS 17 program. The results showed that the BIPV (building integrated photovoltaic) system (i.e., CASE 1) and BIPV and BIST system (i.e., CASE 2) shows 42% and 29% of plus energy rate, respectivey. Also, CASE 1 can generate 59% more surplus energy compared with the CASE 2 under the same installation area.

This case study is aimed to establish design and construction methods to establish Korean-type plus energy house. First of all, this study made a literature survey on the standards and performance requirements of Passive House established in Germany and introduced design and construction process of plus energy house that is being constructed. Unlike general process of building design in Korea, passive house planning includes energy performance of each factors and analysis of various design factors to achieve an energy-efficient building. To meet the standards and requirements of tile passive house, we have to consider design factors such as not only the layout, shape, and facade of a building but also the performances of building envelops including its insulation types and window systems.

<P><B>Abstract</B></P> <P>This study proposes an independent dedicated outdoor air system (IDOAS) for energy-plus houses under the humid subtropical climate located in Daejeon, South Korea. The proposed IDOAS can be used as a stand-alone ventilation and dehumidification system. In order to investigate the energy efficiency of the IDOAS, four different types of systems are simulated including the conventional dehumidifier (i.e., Case 1) and conventional dedicated outdoor air system (DOAS) (i.e., Case 2). The first IDOAS (i.e., Case 3) is designed such that the evaporator of the heat pump is located at the supply air (SA) side and the two separated condensers are located on the SA and exhaust air sides, respectively. The second IDOAS (i.e., Case 4) has a direct evaporative cooler located on the exhaust air side to improve the heat extraction rate. It is shown that the conventional DOAS and IDOAS-2 yielded the highest energy efficient system.</P> <P><B>Highlights</B></P> <P> <UL> <LI> An independent dedicated outdoor air system was proposed for an energy-plus house. </LI> <LI> The energy saving potential of the dedicated outdoor air system was investigated. </LI> <LI> The proposed system saved 37% of operating energy compared to conventional systems. </LI> <LI> The proposed system generated 38% more surplus energy via the conventional systems. </LI> </UL> </P>

Due to increasing problem of depletion of traditional fossil fuel such as coal and petroleum alongside of effort to contral Carbon Dioxide gas emission, need of alternative energy becomes top priority. Amongst many alternative energy solutions, Piezoelectric energy harvesting system, transforming wasted kinetic energy such as pressure and vibration to electronic energy, became top research. Unfortunately, only research regarding battery efficiency in Piezoelectric energy harvesting system is widely conducted on. There are hardly any research regarding system installation in structure yet. Thus, this paper is conducted by Piezoelectric energy harvesting system and monitoring system installed in university building"s hallway and stairs with 50 of two different types of gender subjects. With gathered data from different accumulation of energy between modules, video analysis with footprint distribution ratio of subjects, this paper presents analysed data of different accumulation of electricity with differentiation of module install location along with aspect of accumulation of electricity. Also, this paper predicted the amount of generation of electricity in the same area through analysis of electricity accumulation based on distance between modules.
