  • Under the regulation of rational energy use in public institutions, it has been mandatory for educational facilities to meet the first grade or higher since 2014. Also the regulation has forced educational facilities as public institutions to use renewable energy since September 2008. Educational facilities are required to be qualified as zero-energy buildings from 2020 under the revision of the Green Building Act. In this study, we identified the current status of the building energy efficiency rating system and the renewable energy system installation for 316 educational facilities that were accredited as "building energy efficiency rating system" from February 2015 to March 2019. Also we analyzed the energy self-sufficiency rate based on energy requirements and renewable energy output. Of the 316 facilities, 12 had 1++ and 293 had 1++ for the "Building Energy Efficiency Rating System". Among the 12 facilities which had 1+++, 11 recorded ZEB level 5 or higher, and 28 out of the 293 facilities(11%) which got received 1++ had ZEB level 5. Thus, it is impossible to implement the ZEB certification system for educational facilities under the present conditions. Expanding the ratio of 1+++ and investing in renewable energy systems should be preceded.

  • 한국수자원공사 전북지역본부는 2009년 1월 전북 전주시 여의동에 본부신축공사를 착공하였다. 같은 해 12월 정부는 저탄소 녹색성장을 위해 신축 공공청사 건축물에너지효율 1등급 취득 의무화 제도를 시행하여 2010년 1월부터 신축되는 모든 공공청사는 건물에너지효율 1등급 취득이 의무화 되었다. 전북지역본부와 같이 진행중인 건축물에 대해서는 강제성은 없고 에너지효율 향상을 위한 제반 조치 마련토록 권고하였다. 그러나 전북지역본부는 정부정책과 공사 이미지 제고를 위해 진행중인 공사에 대해 건축물 에너지효율인증등급 향상을 위한 개선 방안을 수립하고 설계변경을 통해 결국 1등급 인증을 획득하였다.

  • 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.

  • As entering in the time of high oil price, seriousness of an energy is on the rise and the importance of energy is growing. Especially, building energy occupying 24% of total demand of energy is expected to be possible to reduce energy demand more than other section. To reduce the building energy consumption, this study analyzes function and thermal performance of Super window by heat experimental apparatus. Super window is a 2-track low-e glazing window for high insulation efficiency. By applying the results of this experiment to building energy efficiency rating tool, this study compares energy efficiency rates depending on a region.-Jeju, South, Central. And it shows how much does Super window reduce Building energy consumption.

  • Enhancement of exterior's insulation performance like wall or window etc. is general way for building's energy efficient and thermal performance. But exterior's opening plan is important for minimizing the energy consumption and heat loss. In this paper, energy saving rate will be analyzed and compared considering the window area's rate and window's SC(Shading Coefficient) in a apartment with Building Energy Efficiency Rating System's evaluation tool. In the process of evaluation, energy saving rate is measured at each stage of the window area's rate from 20% to 60% every 10% term and the shading coefficient value from 1.0 to 0.6. As a result of this research, energy saving evaluation could not be measured exactly with existing evaluation tool. Accord this research, Building Energy Rating System's evaluation range is needed to be broaden for exact evaluation of energy saving rate.

  • According to the building regulation U-value limitation of window is $3.3W/m^2{\cdot}K$ in southern regions, while U-value limitation of wall is $0.35{\sim}0.58W/m^2{\cdot}K$. It means that the energy loss through windows is five times more than it through wall. Therefore, this study analyze how much it has affected building energy rating when the insulation performance of windows and walls is changed by building regulation. In conclusion, in order to obtain 2 rating thermal performance of windows is improved more than 10 percent of U-value limitation and it of wall is improved more than 20 percent. The thermal performance of windows is improved more than 20 percent of U-value limitation and it of wall is improved more than 30 percent to receive 1 rating.

  • Generally, the building's windows and ventilation for the purpose of mining and the vista and windows by emotional engineering design area is a growing trend.In addition, the building regulation U-value limitation of window is $3.3W/m^2{\cdot}K$ in southern regions, while U-value limitation of wall is $0.35{\sim}0.58W/m^2{\cdot}K$. It means that the energy loss through windows is six times more than it through wall. Therefore, the purpose of this study is to evaluate the environmental performance of the super window system by verification experiment. The results of this study are as follows; 1) The insulation performance of super window system is $1.44\;W/m^2^{\circ}C$ 2) Super Window compared to a normal window reduce heating energy requirements have been 5.3% 3) Compared to a normal window, Super window savings rate was 4.1% lower 4) Building energy efficiency rating was up to 1 rating from 2 rating.

  • Entering in the time of high oil price, seriousness of an energy effect sector has given a huge impact and the importance of energy is growing. Especially, building energy occupying 24% of total demand of energy can be expected to reduce energy demand more than other section. To do this, the Building Energy Rating System is applied and implemented in Apartment houses on Jeju, South and Central region. This system calculates into energy saving rate, and certifies the building energy rating. This study evaluates the energy saving rate and rating and compares the difference in energy savings considering to each region and the thermal performance of the window. In result, the standard of the assessment house which is applied to the build energy rating system is demanded to distinguish the thermal performance of window according to regional variation.
