Indoor environmental quality in Korean green building certification criteria—certified office buildings—occupant satisfaction and performance

The aim of this study is to evaluate the indoor environmental quality of workplaces in Korean green building certification criteria-certified office buildings in Korea. A post-occupancy evaluation of two green and two conventional office buildings was conducted. Occupants (N = 222) completed a paper-based questionnaire related to perceived environmental satisfaction and performance. The study compared nine indoor environmental quality criteria in relation to occupant satisfaction and performance between Korean green building certification criteria-certified and non-Korean green building certification criteria-certified office buildings. The data were analyzed by descriptive statistics. The study found that in both cases (Cases 1 and 2) Korean green building certification criteria-certified buildings had better satisfaction scores in office furniture, cleanliness and maintenance, lighting, and thermal comfort quality than did non-Korean green building certification criteria-certified buildings. The study also found that in both cases (Cases 1 and 2) Korean green building certification criteria-certified buildings had better performance scores in lighting and thermal comfort quality than did non-Korean green building certification criteria-certified buildings. Office layout, office furniture, cleanliness and maintenance, lighting, thermal comfort, indoor air and indoor public space qualities have a higher influence on overall satisfaction and performance than other indoor environmental quality criteria. This study shows the value of some indoor environmental quality criteria that show a strong positive association with overall satisfaction and performance enhancement, but are not yet included in the official Korean green building certification criteria list of indoor environmental quality categories.

Sound Insulation Performance Evaluation of Military Facility by Modular System

A modular system is an industrialized building system that is transported to the field and assembled in a short period of time. This system shortens the construction time, ensures high-quality and reduces on-site labor costs. Recently, the construction of modular military facilities has increased because of the characteristics of military facilities. Accordingly, a modular system has been used in bachelor officer’s quarters (BOQ) and barracks. An inhabited military facility needs to be of apartment house quality. In various requirements of house quality, the sound insulation performance is considered important. In this study, the sound insulation performance of a modular system was evaluated in a constructed military facility. As a result, the BOQ satisfied the performance level of the ‘Floor impact sound insulation structure Accreditation and management standard for apartment house’ and ‘Green Building Certification Criteria’.

The purpose of this study is to analyze the usage of eco-friendly elements in Korean traditional architecture to evaluate Hanok(Unjoru and Jinwondang) according to Green Building Certification Criteria(G-SEED). The results of this study were as follows; Unjoru and Jinwondang was not enough to obtain certification points. From Site usage and Traffic category, Jinwondang gets more points than Unjoru. It`s because Jinwondang is located in downtown Seoul, so it gets more points of traffic and neighborhood facility. From Energy and Environmental Pollution category, Jinwondang gets more points of energy performance than Unjoru, too. It`s because Jinwondang secured insulation performance of wall and windows using insulator and glass. From Resources category, Unjoru gets more points than Jinwondang. It shows that modern Hanok was limited using natural resources. From Ecological Environments category, Jinwondang is located urban area, it`s difficult to secure the open space, so Unjoru gets more points than Jinwondang. If Modern Honok installs a system that can getting point and secure insulation performance, it will be certificated according to G-SEED.

Assessment Items of Outdoor Environment through Analysis of SITES - Focused on the Comparison with G-SEED and LEED -

Although assessing outdoor environment and green space in terms of sustainability and environmental performance is perceived as an important issue, most existing green building certification systems are more focused on buildings and indoor environment. Recently, the Sustainable Site Initiatives (SITES) has been developed by American Society of Landscape Architecture in order to evaluate sustainability of site development and outdoor environment. Separate from LEED, the SITES are increasingly receiving attentions as a reliable certification system in the United States. As a preliminary study to develop the items of outdoor environmental assessment, the present study is purposed to analyze the assessment items, grading system and applicability of SITES for better understanding on the system. Also it was compared to existing green building certification criteria, including G-SEED, LEED-NC, and LEED-ND in order to investigate similarities and discrepancies. The results would provide insights and basic data to improve assessment items for outdoor environment of G-SEED.

A Comparison of Plan and Facility Items in Green Building Certification Criteria - Focused on Energy-related Items in Schools -

Low-energy consumption and low-carbon emissions are global issues and a challenge for all countries. In this context, the green building certification criteria in the construction industry needs to be refined in order to focus on energy-related items in schools. In particular, energy-related plan items do not incur costs in terms of use and maintenance and their initial installation cost is usually less than that of facility items. Their installation should therefore proceed first in order to reduce the costs or building energy consumption for green growth. Consequently, this study provides basic data for improving the green building certification criteria based on findings from a survey on green certification criteria, energy-related items of 17 schools that possess the certification, and the plan items and facility items of those 17 schools. The findings of this study can be summarized in two key points. First, the energy-related items in the energy sector need to be professionally managed and evaluated. Second, plan evaluation items in the energy-related plan items need to be introduced and a minimum score criteria for plan items needs to be suggested to encourage the installation of plan items.

Study on the introduction and assessment of the Life Cycle Carbon Emissions in Office Buildings

Global warming has become a major issue all over the world. Noting the carbon dioxide emissions as a main contributor to global warming, we studied on the methods to reduce the life cycle building carbon emissions. Green Building Certification Criteria(GBCC) has been implemented since 2002 in Korea, but it doesn't estimate the quantities of the CO2 emissions. Therefore, we studied the ways to implement the CO2 emissions in quantity to GBCC. We select a government building which was rated excellent by the GBCC. This office building was regarded to excellent building by GBCC but not good for energy consumption. It was found energy glutton buildings for research by the Ministry of Public Administration and Security in 2010. This part of GBCC is need to be improved. Also LCA (Life Cycle assessment) was carried out to estimate on carbon footprint on this office building. So we need to implementing quantitative evaluation on the amount of carbon emissions by GBCC. And it is possible to implementing quantitative evaluation on the amount of carbon emissions. Through this study, we expect that quantitative assessment of life cycle carbon emissions of buildings by the GBCC. Also expect to reduce the carbon emissions of the building by improving the GBCC.

The seriousness of greenhouse gas exhaustions and energy use of the building has increased, the world is making an effort with many requests and the consultation for sustainable development. For this reason, Green Building Certification Criteria has been implemented to reduce environmental load, high-performance and environmentally friendly in the United States, the United Kingdom and Germany. In response to the global trend like this, the Korean Government has induced the eco-friendly construction and sustainable development to implement the G-SEED (Green Building Certification Criteria of Korea) in 2002. However, in spite of the many authentication result, G-SEED has been pointed out that it needs for improve in the evaluation system of Apartment sector which accounts for more than 40% of the authentication. Therefore, the purpose of this study is to suggest improvements in the evaluation system. To achieve this, this study have selected for LEED, BREEAM, DGNB of comparison target, drawn improvements through comparing transition process in G-SEED.

A method for evaluating the performance of green buildings with a focus on user experience

Since the early 1990s, various green building rating systems have been proposed and continuously elaborated through exhaustive studies. Most efforts in this area can be divided into two main parts; (i) development of green building rating systems through identifying relevant rating criteria; (ii) assessment of building rating systems for validity. Studies on the rating criteria for green buildings have mainly focused on the development of the items for evaluating buildings’ energy performance. Studies on the assessment of building rating systems have emphasized the effectiveness of such systems. The existing studies in this area adopt mostly quantitative methods, so there is a lack of qualitative evaluation regarding users’ interaction with green buildings. Our research aims to develop a method for evaluating green building performance, which includes user experience. In order to assess the proposed method, we conducted a case study, in which we used Korea's Green Building Certification Criteria (KGBCC) to evaluate the performance of a KGBC-certified green apartment. We have used a customized method, with a focus on user-oriented factors, to present the results.

Many countries have made their best to protect the earth from global warming and to find solutions for the reduction of carbon dioxide emittion and energy consumption. Especially, buildings have emitted over 40% of carbon dioxide against whole quantities emitted to the earth. Therefore, the reduction of carbon dioxide emitted from buildings require to save the earth environment. Energy consumption of buildings in Korea has reached 24% of total energy quantities, and energy consumption of collective housing has been continuously increasing. So, Korea government has also executed the Green Building Certification Criteria(GBCC). The GBCC evaluates the 8 types of buildings - collective housing, office, school, etc - to certificate the green building. In this paper, the evaluation items of collective housing in GBCC were reviewed to be used as the reference data for future revisions by the case studies. According to the results of this study, current version of GBCC requires additional revisions about the evaluations of energy consumption monitoring, commissioning and existing building.

A Study on the Direction of Revision for Green Building Certification Criteria on Office Building - Focused on the Comparison with LEED and BREEAM -

The objective of this study is to propose the direction of revision for Green Building Certification Criteria(GBCC) on office building with comparison analysis to LEED(USA) and BREEAM(UK). Korean GBCC has been developed for both residential and non-residential building, and GBCC for office building has been becoming a reference for other non-residential building. In this paper, Korean GBCC for office building was reviewed to find out current problems, and compared to foreign certifications to propose improving points for sustainable architecture with reliability. Before compared with LEED and BREEAM, the definition and the design methodology of sustainable building were reviewed and objectives and practical contents of GBCC were figured out Korean and foreign certification criteria have been analyzed as TBL. The result shows that item number and flexibility of GBCC were not sufficient to become a guideline for architects. Korean and foreign certification was focussing on environmental sustainable matter. Social sustainable matter were not widely considered and mainly focussed on improvement on interior environment. Consequently, new contents on social aspects were required in to current GBCC for sustainable architecture. Many of Korean architects were putting effort on achieve green building certification to accomplish sustainable architecture. GBCC could be a role as guideline well as certification criteria. More contents on social aspects, detailed certification standard, and flexible items are needed for better system on sustainable architecture.

Life-Cycle Cost Analysis on Glass Type of High-Rise Buildings for Increasing Energy Efficiency and Reducing CO2 Emissions in Korea

As the heights of high-rise buildings increase, their building area and elevation area also increase, consequently increasing their yearly energy consumption. Energy efficiency has become an even more important issue, especially when glass is used for a building’s exterior. In this study, the life-cycle cost (LCC) of the exterior glass of high-rise buildings was analyzed from the perspective of energy efficiency and CO2 emissions. First, the LCC was analyzed according to changes in the selected types of glass. Reflective + Low-E (Type 1), double Low-E + Argon (Type 2), and triple Low-E + Argon (Type 3), which satisfy green building certification criteria and were used in the past for high-rise buildings in Korea, were selected as the exterior glass types. These types of exterior glass were applied to a case building and compared with the Low-E glass that was the existing glass type of a case building. The economic benefit of selected glasses for 40 years was greater in the order of Type 1, Type 3, and Type 2 compared to the existing glass. Second, these types of glass were applied to each orientation of the building. By changing the glass according to building orientation it is shown that in the east, west, and north, Type 1 was most economical, whereas Type 3 was most economical in the south. The results of this study will contribute to the improvement of energy efficiency, CO2 emissions reduction, and cost efficiency of future high-rise buildings.
