In recent years, Korean government has focused on improving the environmental impact of products in order to reduce greenhouse gas emissions and to achieve their energy goals. The government has been conducting the following polices such as green procurement inducement and certification system. After carbon labeling was conducted in 2009, among a total of 1,065 items, 97 building materials have been given a certification: finishing materials items have the highest weight (56%). The increase in the certification numbers shows that there has been considerable technical efforts in the building material industry. At the awareness of carbon label and purchase of low carbon product, however, customers are aware of carbon labeling but the purchasing rate of carbon product is low. In this paper, we suggest that low carbon activities must also be considered in order to create client value by adding the concept of ecological efficiency. The objective of this study to measurer the eco-efficiency of carbon labeled building materials on the basis of environmental aspects of the product with the perspective of economy for purchasing the excellent products.

The concepts of interior design work have set forward an aesthetic and functional proposition to be answered by those who design spaces. The available range of suitable materials for interior use appears to be almost inexhaustible in this day and age. Now a day, relatively new fields of study on environmental-friendly interior examine humans'innate affinity for health and explore its implications for architecture and the built environment. A growing field of research suggests that spaces' relationship to aesthetics and environment can either help or hinder their occupants' health and wellness, productivity, and even their creativity. This paper presents several examples of already built apartment houses in practice, and discusses the demand of users of the spaces for health and sustainable environment, deepening the relationship between newly-constructed spaces and the remodeled ones. The considerations to some new and contemporary materials from the aspect of healthy indoor architecture design are presented in this paper. Designers need to rethink the conventional and high-tech interior environment in apartment houses with respect to perceived air quality, material emissions, and odors. The future of interior design is oriented on light shapeable materials which are able to create a unique memorable atmosphere. The primary assignment in accepting recent materials and proceedings is our responsibility to creating proposals, that are mainly safe, hygienic and environmentally proper.

This paper is an outgrowth of many years of practicing real interior work projects and one of my responses to the question not only about the actual dimension of interior work surface but also about the classification of contemporary finishing materials in basic interior project of high-rise apartment houses. For this purpose, 8 conventional apartment units which are already-built or designed have been surveyed and the results are interpreted in the form of proportion of space and finishes. The data can be applied to make up a schematic design in the selection of environment-friendly interior works and assessment of the degree of sustainability. For further study, the basic data provided here can be used as an index to differentiate the occupants' desire toward green interior design for their own apartment spaces, comparing to the conventional interior work in the Korean market. Not surprisingly, wall paper is dominated to make the interior surface in apartment houses. In the percentile of the utilization of finishing materials, wood-flooring and coating materials like wet paint also ranked at the upper position.

Interior material covering as the final process of house-building, critically influences not only aesthetic character but also air quality of indoor space. Wall covering today, however, caused a serious social problem because of chemicals contained in the industrial wallpaper and artificial glue. In this context, Korean traditional wall covering of Han-ji can be an alternative model due to it's ecological character. Recently 'Hanok' attracts public attention, since society and people become to appreciate the unique beauty and value of our traditional culture. The values include natural beauty, emotional character, and environment-friendliness. Recognizing this, this paper intended to scrutinize the operating process of Han-ji as an interior finish material. Historical research method was employed, tracing the related articles in old literature and interviewing with the witness of the experienced expert. Thereby, healthier and unique aesthetic indoor environment can be expected to be sustainable along with the rich cultural life of ancestors.

Recently, a bed company's product has detected a certain level of radon or higher, making it a popular search word on portal sites. Because of this problem, people are becoming more interested in radon. The government plans to support the establishment of a radon alert system for households through a radon concentration survey of 10,000 households. The use of palm charcoal as an indoor finishing material will reduce the risk of lung cancer through radon reduction. The experiment used a method of replacing palm activated carbon with blast furnace slag, and the adsorption performance of radon tends to increase as the replacement rate of palm activated carbon increases.

The railway platform is an important facility closely related to the safety of passengers, trains, and images of railway facilities, and requires thorough facility management. However, the problem that the finishing material (plastering mortar) for the joint finishing of dissimilar materials (concrete+granite) falls off in the direction of the track at the platform podium is occurring multiple times across the country. Since these problems threaten the safety of train operation and the safety of passengers, immediate and continuous management is required. This study tried to derive improvement plans through the analysis of the drop-off problem of finishing materials occurring at the platform podium. The status of missing finishing materials for the platform podiums of about 200 railway stations and the related design and construction standards of the Korea National Railway were investigated. After that, the cause of the drop-off of the finishing material was analyzed, and as a result, it was found that the main cause was the boundary between the roadbed and the architectural process that occurred during construction. Subsequently, in connection with the derived causes and design, construction standards, (1) improvement of finishing materials or construction methods, (2) design of finishing materials that are easy to adjust height, (3) design of separate finishing methods, (4) improvement methods and durability were suggested.

This study examined emission characteristics of far-infrared ray, formaldehyde, volatile organic compounds and deodorization rate of particleboard prepared at different target board densities and resin content levels, using the xylem part of Broussonetia Kazinoki Sieb. The deodorization rate increased, as the target density of board and resin content increased. Emission rates of the far-infrared ray and total volatile organic compounds (TVOCs) were 0.892~0.899, and $0.074mg/m^2{\cdot}h$ for particleboard prepared with the resin content of 13% and target density of $0.6g/cm^3$ while the deodorization rate was 80~90% for the same particleboard. The formaldehyde emission factor ranged from $0.004mg/m^2{\cdot}h$ to $0.006mg/m^2{\cdot}h$ for all particleboard fabricated at different resin content and target densities. These results indicate that particleboard prepared from the xylem part of Broussonetia Kazinoki Sieb have a potential as a building construction material.
