  • Various programs have been developed to predict the energy consumption of a building as a result of recent increased social interest in the environmental friendliness of construction as measured by energy efficiency. The goal of environmental-friendliness, which is achieved by predicting the energy consumption of a building, can be realized in the design stage by applying a variety of technologies, planning factors and planning systems. However, most energy analyzing engines are only suitable for use in the advanced stages of design because of the large amount of design information that must be entered. Thus, because the simulation programs currently used are not suitable for use in the early stages of design, this study suggests a prediction logic that provides an overview of the energy consumption of a building according to its size, scope, and purpose by analyzing statistics collected by government agencies.

  • This paper presents a basic energy performance data of micro gas turbine, Renewable Energy(BIPV and Solar Collector System, geothermal system) and a hybrid energy system(geothermal system and microturbine) installed in Hospital Building. The efficiency of solar collector and BIPV system was 30%, 10% individually, and lower than micro gas turbines. Micro gas turbines are small gas turbines that bum gaseous and liquid fuels to produce a high-energy exhaust gas and to generate the electrical power. Recently, the size range for micro gas turbines is form 30 to 500kW and power-only generation or in combined heat and power(CHP) systems. Finally, in energy performance aspect, Micro gas turbine system and hybrid energy system were high-efficiency system in hospital building. Hybrid energy system also give us a powerful alternative energy system economically.

  • This study is a study on the building integrated method of Photovoltaic. It was analyzed into a basic installation condition and an integrated form in this study. And it was confirmed through the 3D simulation & drawing work of an integrated situation to the real domestic building. The Photovoltaic installation of the country to an optimal efficiency for the year must be installed to the due south with an angle of thirty degrees. And also a module spacing must be more than doubled from the bottom to the top of module to prevent from efficiency falling by a shadow of photovoltaic module in a roof setting of flat roof. If Photovoltaic module is an adequate material that is a basic requirement as a building's finishing material, it's not only an efficiency of alternation with an existing finishing material but also a building's design element.

  • The purpose of this study was to clarify precautions during the design and operation phases for energy reduction in a public office building. To check the operation status of the building, we measured the indoor temperature and humidity in the office space of the building installed central heating and cooling systems. And we analyzed these data and annual BEMS data. As a result, we found six problems related to decreasing system efficiency. Based on these, we presented the information to improve the efficiency of the system from the design and operation phase. Also, we present the need for a system to support the decision-making of operational managers in real-time for the energy efficiency of the building.

  • As a reasonable energy policy has become required because of consuming substantial amounts of oil than others, the studies on energy consumption are in work for energy savings of buildings that spend up to 24% of total energy consumption. However, there aren't basic data on energy consumption and installationregulations for effective equipments in energy guzzled buildings. The best plan to reduce the building energy consumption is that the insulation performance should be improved because the insulation and airtight of building envelopes have an effect on the energy consumption basically. Thus, we should prepare the alternatives to improve insulation performance of envelopes and the efficiency of insulation performance of the window for reducing energy consumption.

  • Currently the country's foreign energy dependence reaches approximately 97% and the total energy consumption percentage of buildings(commercial and domestic parts) reaches approximately 24%. Building energy saving by enhanced insulation will be very important issue. Therefore, the solution is required to reduce energy loss and increasing displeasure caused by excessive influx of solar energy through windows, to solve the problems like decoloration on indoor furniture an clothes by harmful ultraviolet rays, air conditioning and increased cost. This research used for commercialization and ills semination by basic information through a evaluation on insulation performance of the window of high efficiency energy equipment which can improve the insulation performance.

  • Tall building has some controversial aspects with low carbon city, but it is still a sensible choice for the metropolitan city. This paper aims to develop holistic urban design strategies to minimize impacts on the environment, increase energy efficiency and improve the quality of living in tall building communities by utilizing tall building characteristics. It puts forward the concept of integrated tall building-low carbon community design from the perspective of urban design, and summarizes five core strategies: Temporal state based on energy use, Complementary energy use state based on functions, Spatial state based on regional environment features, Transportation state based on low-carbon lifestyle and Waste utilization state based on tall building characteristics. It also applies the strategies to a practical project. The results show that the proposed urban design strategies are available approaches to mitigate the side effects of tall building on low carbon city.

  • 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.

  • 국내 건축물은 국가 온실가스 배출의 25%, 에너지소비의 20%를 차지하고 있어 건축물의 에너지 효율향상이 국가 에너지수요관리의 주 대상으로 인식되고 있다. 건축물의 에너지효율향상을 위해 "제로에너지건축물 국가 로드맵"을 작성하여 정책들을 시행하고 있으며, 제로에너지건축물 의무화 확대의 따라 조기 활성화를 통한 국가 건물에너지 수요관리 효율성을 제고 하고 있다. 또한 건축물이 완공되고 그 후 에너지절감량에 대한 성과검증에 대한 필요성 또한 높아지고 있다. 이에 따라 건축물의 에너지 성능을 평가하기 위한 방법들이 제시되어야 할 것이다. 본 논문은 국제표준 및 가이던스 분석과 동시에 국내 학교를 현장 방문하여 각종 변수 등에 대한 조사 분석을 통하여 국제적으로 적용 가능한 제로에너지스쿨의 에너지성과검증 방법을 개발, 제시하고자 한다.
