The government has enforced Housing Performance Grade Indication System (Article 21, Paragraph 2 of Housing Act) starting January 2006 for the purpose of giving users in hope of toying an apartment opportunities to select housing based on personal preferences by providing information on housing performance at the time of tenant recruitment announcement as well as securing desirable environment (comfort) by encouraging construction companies to build housing of the indicated performance level. The acoustic performance indication items include three items such as floor impact isolation performance(light weight impact sound, heavy weight impact sound), bathroom noise and insulation performance of boundary walls between households. This paper explains the background, the basis of creation and evaluation method focused on the acoustic environment performance helping for the developer of technique and a staff in charge of construction business who cope with this system.

It is required that an evaluation method that can present the performance after remodeling to residents objectively as the increase in demand for remodeling. New construction is able to evaluate through housing performance grading indication system. However, there are some parts that are difficult to apply as assessment criteria of new construction in remodeling. The purpose of this study is to establish the assessment criteria direction for each item in remodeling performance evaluation. In conclusion, we set up institutionalized items for remodeling performance evaluation, and propose to assessment criteria direction based on the characteristics of remodeling on extracted items.

In this study, I evaluated toxicity that analyze performance of flame-retardant about flame-retardant painting wood and combustion gas that is based on the toxicity index. Processing condition of flame retardant solution and treatment method of samples didn't affect greatly to performance of flame retardant. Occurrence of combustion gas showed a almost similar result from the sample which spraying flame retardant solution and toxicity corresponds to high level, Hazard Class III, and the flame retardant solution saturation sample which makes put out Hazard Class II which is a low toxicity relatively.

This paper presents various attempts to secure the floor impact sound insulation performance on the dry floor system of steel framed modular house that lately attracted domestic attention. Test results show that in the condition of using dry floor system of D31(D32), the light-weight impact noise performance records the top level in the floor impact sound insulation performance grading system. the heavy-weight floor impact noise performance meets the minimum sound level limit in the floor impact sound insulation performance grading system that enacted regulation on housing construction standards.

This study aims to suggest improvement plans and explain about the current situation for facilitating Long-life housing, based on the results on flexibility items among 27 items consisting the "Housing Performance Grading System". From the 9th of January, 2006 to the month of July in 2011, study has analyzed evaluation results on 216 different types for each grade and reviewed evaluation criteria and methods. Current evaluation criteria applies quantitative analysis, by calculating in percentage how much bearing walls and columns, which hinder flexibility, take up space in the household. The evaluation rate for each household was assessed in relation to its structural system, and a higher grade was given to column-typed structures. In addition, to facilitate long-life housing, this study extracted harmful factors, expanding the range of evaluation. The first step was to evaluate structure, which is the basic element. The second step can to evaluate the probability of applying resources in response to the changes of structural systems. As The third step, Flexibility item will evaluate the probability of moving the water-using area, suggesting gradual approach. Thus, through evaluations of flexibility items, the study aims to improve the quality of life in household, by avoiding uniform structures and acquiring more freedom for space designs.
