The objective of the article is to assess acoustic insulation of a wooden floor structure between stories in a pre-war residential building. The measurements involved acoustic insulation against impact sounds and airborne sounds. The article presents the results of acoustic tests for noninsulated floors and then for floors insulated with mineral wool. First, the results of the research were analyzed in terms of single-number acoustic insulation rates. These results were compared to the standards and findings described by other researchers. Then, an analysis was carried out for the processes as a function of frequency. The conclusions described in this article allow us to assess the applied acoustic insulation system.

The outer-wall thermal insulation system has been wide used in civil engineering as an effective energy-saving measure. At present, the organic flammable thermal insulation materials such as EPS and XPS are used in outer-wall thermal insulation system in China, which leads to great fire damage probably. The rock-wool is described in detail on its merits such as good thermal insulation performance, good sound insulation performance, light weight, low thermal conductivity coefficient, incombustibility, innocuity and stable chemical capability. Two popular outer-wall external thermal insulation systems are introduced. The construction sequence of the outer-wall external thermal insulation system with rock-wool slabs, mortar and thin layer plastering technology is described.

The paper aims to evaluate the psychological factors of the comfort performance of the hanok. This is to guide restoration and improvement in consideration of the intangible variables that provide the quality of the hanok. Through this process, we ultimately intend to build an integrated residential performance evaluation system that includes factors related to the quality of residents’ lives, such as the comfort of their surrounding and indoor environment, as well as the functionality and convenience of the hanok, a representative type of Korean traditional architecture. The test method to evaluate the comfort performance of hanok is largely divided into the physical perception element, which is a quantitative indicator, and the psychological cognitive element, which is a qualitative indicator. Physical perceptive factors are composed of nine quantifiable factors that can be measured by numerical values, namely humidity control, condensation, insulation, thermal comfort, air permeability, solar radiation, solar lighting, sound insulation, and air cleanness. This is a perceptual concept of viewing a building as it is, and a quantitative evaluation method of measuring data in the field using environmental sensors and equipment. Psychological cognitive factors that are evaluated based on the experiences of users (residents) living in hanok, are classified into five categories, of scenery, beauty, deodorization, usability, and health. This study was conducted through a questionnaire between experts and users (residents), limited to the psychological factors among methods of evaluating the comfort performance of hanok. As a result, it can be seen that environmental factors are the main variables that influence the degree of satisfaction with the psychological perception factor. This might be a merit factor of general hanok, and weight could be given when creating an integrated standard in the future.
