Currently energy use planning council system is mandatory especially for the urban development project planned on a specified scale or more, The goal of existing demand prediction was to calculate the maximum load by multiplying energy load per unit area by building size, The result of this method may be exaggerated and has a limit in the information of period load, The paper suggests a new forecasting process based on standard unit household in order to upgrade the limit in demand prediction method of multi-family housing complex, The new process was verified by comparing actual using amount of multi-family housing complex to forecasting value of energy use plan.

This study is an early stage to carry out a quantitative evaluation of energy savings through efficient operation of buildings. To this end, the occupant’s behavior was analyzed based on the field measurement results of the passive house. The behavior was analyzed for occupancy, window opening and closing, external blinds, heat recovery ventilator, and indoor thermal environment. In the case of the window opening and closing behavior, the occupant’s behavior of the normal residential was different, and the external blinds were not functioning properly. And the analysis results were reflected in the simulation model. The created model was calibrated for the indoor temperature and the energy useage of the heat recovery ventilator. In the future, we intend to develop an algorithm that supports residents to efficiently operate the passive house.

In this study, the occupant behavior of window operation in residential buildings was implemented and dynamic building energy simulation was also conducted to examine the effect of the behavior reflection on natural ventilation rate, energy demand and thermal comfort. The process of using EMS(Energy Management System) and AFN(Air Flow Network) has been carefully proposed in order to realize the stochastic behavior model on the simulation. The energy demand and thermal comfort based on the behavior was reviewed. The results show that window operation was realized toward cooling energy reduction as well as comfort satisfaction through natural ventilation in summer. Further, when the ventilation rate was fixed, the thermal comfort was lower than other behavior models. In the future, it is necessary to develop a behavior models suitable for the domestic residential culture. In addition to window opening and closing, if behavior models for the operation of heating and cooling equipment were developed, it will be able to predict the building energy consumption with a more accuracy.

The integration of passive elements in building design is proven to lead to minimization of energy loads imposed to a building. Nowadays, with one step forward, much effort is made to achieve zero energy in multi-house by introducing new and renewable energy facility to a building. The present study aimed at estimating the cost for renewable energy facility adopted to achieve zero energy in a multi-house after calculating the present cost for energy consumption as well as energy loads at the existing multi-house. At the same time the study evaluated the reduction effect in energy load and cost in cases of integration of passive design and high efficient energy-related equipment and materials. As a result it was analyzed that cost reduction and cutdown of energy load be achievable up to approx 50% as a whole. In an attempt to recognize the initial investment on introduction of renewable energy equipments and its type and payback period, it was found that what needs the longest payback period is solar energy generating equipment with up to 57 years, while the shortest is geothermal power generating equipment with 8~9 years.

The dissemination of green architecture is one of the representative strategies of the architectural sector for the preemptive implementation of government-backed goals of increased greenhouse gas reductions. One implementation method is to realize zero-energy buildings through the convergence of passive houses and new and renewable energy. Energy self-sufficiency in residential buildings can be accomplished by the fusion of fuel cells with other renewable energy sources. To apply a fuel cell to a building, predictions of a building’s energy consumption and fuel-cell energy production should be conducted simultaneously. Although many existing studies and tools have been developed for predicting building energy consumption, research on the application of fuel cells to buildings remains insignificant. This study aims to derive an energy performance prediction equation for a 1-kW polymer electrolyte membrane fuel cell. To this end, operational data based on the partial load ratio were collected and analyzed, and the heat and power energy production and fuel consumption prediction equations of the corresponding fuel cell were derived.

Surface properties, including the texture and the luster, of cotton fibers and yarns thereof play an important role in textile technology. The convolutions and the cross-sectional shape of the cotton fiber affect the fabric texture and the luster accordingly. Mercerization of the cotton fabric affects the luster, strength, and other properties of the fabric. In this study, the effect of mercerization was examined on the luster of the cotton fabric, together with the effect of polishing treatment. One of the traditional methods determining the fabric luster is the use of glossmeter or goniometric glossmeter. The use of glossmeter gives successful results in determining the gloss of rather flat and continuous surface such as plastic sheet, painted surface, or paper products. Since the textile fabrics have diverse surface structures and textures, these could be regarded as having three-dimensional surface. Such complexity imposes some difficulties for differentiating subtle surface luster properties of diverse textile fabrics. The advancement in the area of imaging technologies has enabled the micro-scale analysis of the surface textures and the fabric luster recently. Using a CCD camera, the surface luster images were taken at various incident illumination conditions. Microscale analysis, including the blob analysis, of the images could differentiate the subtle luster properties present in a group of cotton fabric samples comprising mercerized cotton fabric, non-mercerized cotton fabric, polished cotton fabric, and a ``standard`` cotton fabric. The glossmeter measurement gave satisfactory but limited differentiation among the samples, whose luster differences are easily recognizable with visual observation, except for the mercerized cotton fabric sample and the non-mercerized cotton fabric. The microscale analysis of the fabric luster could, therefore, help understand the nature of diverse textile fabric luster.
