The aim of this study was to analysis the Heating/cooling performance of Solar Window System built in apartments. The solar window is the idea to integrate daylight as a third form of solar energy into a PV/Solar Collector system and allows more control due to the possibility to close the reflectors. However, there can be a conflict between the desire for on one hand daylight and view and on the other hand optimal energy conversion for the PV/Solar Collector system. The process of this study is as follows: 1) The Solar Window system is designed through the investigation of previous paper and work. 2)The simulation program(ESP-r, Therm5.0, Window6.0) was used in energy performance analysis. The reference model of simulation was made up to analysis energy performance on Solar Window system. 3)Selected reference model(Floors:15, Area of Unit:$148.5m^2$) for heating/cooling energy analysis, Energy performance simulation with various variants, such as U-value of Solar Window system according to its position and angle. Consequently, When Solar Window system is equipped with balcony window of Apartment, Annual heating and cooling energy of reference model was cut down about 5%~11%.

Feasibilities of the application of a micro gas turbine cogeneration system to a large size hospital building are studied by estimating energy demands and supplies. The energy demand for electricity is estimated by surveying and sorting the consumption records for various equipment and devices. The cooling heating, and hot water demands are further refined with TRNSYS and ESP-r to generate load profiles for the subsequent operation simulations. The operation of the suggested cogeneration system in conjunction with the load data is simulated for a time span of a year to predict energy consumption and gain profile. The simulation revealed that the thermal efficiency of the gas turbine is about 30% and it supplies 60% of the electricity required by the building. The recovered heat can meet 56% of total heating load and 67% of cooling, and the combined efficiency reaches up to 70%.

Building energy consumption generally depends on living patterns of residents and outdoor air temperature changes. Although outdoor air temperature changes effect on building energy consumption, there is no calibration method for the comparison before and after Green Remodeling or BEMS installation etc., Big data of building energy consumption are collected and managed by 『National Integrated Management System of Building Energy』 in Korea, and they are utilized for the development of a calibration method for individual buildings as shown as the calibration method for small-area building stocks in the previous research. This study aims to develope a calibration method using big data of building energy consumption of individual buildings and outdoor air temperature changes, and to propose application of appropriate calibration methods for individual buildings or small-area building stocks according to the calibration purpose and conditions.

The performances of the building service equipment relay on the individual superintendent's share for the assessment of performance, fault detection, deterioration diagnosis of the building service equipment. A major use of building energy management system(BEMS) is for monitoring plant and building's energy consumption. National building management system (N-BMS) presented in this study links buildings into a network group in order to monitor and control the buildings. How to construct the N-BMS was considered to save energy resource and to conserve performance of building service equipment. The FEMIS, facility, energy/environmental management & information system, for building service offer management process integrated with BAS, FMS and EMS and so on.

국제적으로 지속적인 이슈가 되고 있는 에너지 절감에 대한 대책으로 다양한 에너지 절감 기술들이 연구 개발되고 있다. 특히 전체 에너지 사용량의 약 20%이상을 차지하는 건물(가정/상업/공공)부문에서는 에너지 진단 및 분석을 수행하기 위해 건물 에너지 관리 시스템(BEMS: Building Energy Management System)과 건물 자동화 시스템(BAS: Building Automation System) 그리고 다양한 환경정보들을 수집하여 활용한다. 하지만 기존 분석 방식은 결과의 신뢰성에 최소한의 영향을 주면서 데이터 관리 효율을 높이는 방법에 초점을 맞춰 연구가 진행되었으며, 이를 위해 기존에 수집된 데이터를 압축하거나 샘플링하는 사전 정제 과정을 거치게 되었다. 하지만 빅데이터 플랫폼을 활용하면 더 이상 신뢰성을 낮추면서까지 데이터를 정제할 필요가 없어지고, 수집되는 모든 데이터에 대한 다차원 분석을 빠르게 수행할 수 있게 된다. 따라서 본 논문에서는 하드웨어의 한계로 기존 건물에너지 진단 및 분석 시스템에서 제공하지 못했던 다양한 분석 및 진단 서비스들을 빠르고 정확하게 제공하도록 하는 빅데이터 플랫폼 기반 건물 에너지 통합 관리 시스템 설계에 대해 서술한다.

In this study, the energy consumption of the typical floor was compared by the total energy comsumption of the building in highrise building. In gerneral, many researchers are studying on the typical floor in highrise buildings for avoiding complexity in energy simulation. But few papers are studied on energy consumption along the floors. In the model bulding, the energy consumption data were acquired by BEMS system in 2011. According the data, the total net energy consumption was $193.99kWh/m^2$ for all area and the total net energy consumption was $247.61kWh/m^2$ for HVACR area. The total electricity and gas energy are used 47.7% for heating and cooling, 33.5% for lighting and plug, 12.9% for conveyance power and 5.9% for restaurant. In comparison of only ground floor, amount of energy consumption in the lobby is 10%, and 90% of total energy consumption is used in the typical floor. For this result, energy simulation on the typical floor is acceptable for calculating the total energy consumption in the highrise building.

The purpose of this study is to analyze the current condition of green building education, which is a necessary condition to activate green architecture, with the need to reduce greenhouse gas emissions in the building sector. The main results are as follows. First, the level of education and the level of domestic green architecture were generally underestimated. Second, in order to increase the satisfaction of participants in green building education, it is necessary to increase the number of courses and to increase the number of lecturers who have excellent practical skills. Third, there is a need to strengthen green building programs related to BEMS and green remodeling. Fourth, it is necessary to expand the education on green architecture for the people in the architectural planning and design field and the related field officials. Fifth, green building education needs to be implemented in conjunction with curriculum of elementary, middle and high school. Sixth, it is necessary to diversify the PR(public relations) channels of the green building education program and to provide a way to give the employment increase point when the curriculum is completed. Seventh, there is a need to expand administrative and financial incentives for green architecture in order to revitalize green architecture education.
