Currently, the global furniture market can not overlook environmental problems due to changes in environmental regulations. In order to grow into a global corporation, environmentally friendly design became essential. In addition, domestic and foreign consumers are increasingly interested in and spending on children's furniture, and demand for environment - friendly furniture for children's health and emotional development is increasing. In the era of universal consumer tastes due to massive mass production, it has been changed into a multi-product small-volume production period that reflects the preferences of various consumers, so that various types of furniture that meet individual preferences are required. Therefore, in this study, we investigated various personal opinions, perception, preference, propensity to use furniture, purchasing points, etc. for environmentally friendly children's furniture, and provided basic data for environmentally friendly children's furniture development that reflects consumer preference and requirements. Accordingly, 243 parents who have more than one child living in Seoul, Gyeonggi, and Incheon were surveyed about the use of children's furniture and the perception and preference of environmentally friendly children's furniture. According to the survey results, 64.57% of the respondents knew about eco - friendly children's furniture and the most popular way to get to know eco-friendly furniture was Internet advertising (49.48%). The rate of recognizing eco-friendly furniture as healthy furniture with no emission of hazardous substances was high as 56.16%. The purchase intention of eco-friendly children's furniture was very high at 86.01% and the most important factor in purchasing was the harmlessness to the human body (56.88%). 59.50% said that it is not possible to distinguish environmentally friendly furniture, which means that there is not much information to consumers yet. In addition, the preferred price range is 500~1000 thousand won, and the preference for the rest furniture is high. In the preferred form type, unit type modular furniture is 36.13%, in the material, wood is 72.35%, in the color, the color of wood with wood grain is high as 45.56%.

"Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Multi-housing residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling project is very unique in that building residents are selected prior to design phase. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.
