“…In the case of wood finishing, the floor thickness and installation methods affect heat transfer from the heat storage layer 14) . As it is shown that the heating performance of the radiant floor heating system is affected by a decrease in the effective floor area for heating because most Koreans use a bed in the bedroom, and a sofa in the living room, we need to consider the partial radiant floor heating in places without furniture.…”

To develop an energy-efficient low-temperature radiant floor heating system in an apartment housing unit from an improved the overall heating system efficiency perspective, it is essential to consider the occupants' thermal comfort and evaluate the thermal environment and thermal output of the radiant panel. This study evaluated the heating performance of a low temperature radiant floor heating system by monitoring the water flow rates, supply and return water temperatures, indoor room temperatures and floor surface temperatures through field measurements, and surveyed the occupants' thermal comfort through questionnaires. Based on the results of field measurements and the occupants' questionnaires, the heating performance and thermal comfort sensation of a low-temperature radiant floor heating system were analyzed. The design considerations of a low temperature radiant floor heating system are suggested.

“…The investigators found that the velocity of thermal transfer for modified engineered flooring, which used adhesives, was faster than that of the laminate flooring, technically showing about 2 °C difference of temperature (Seo et al 2014). They also found that the structure of the flooring, the structure of each component of the flooring, and form of the flooring, has a significant effect on thermal conductivity (Seo et al 2011). In short, there are many factors that influence the thermal conductivity of wood floorings, such as density, structure, temperature, and moisture content of wood (Abdou and Budaiwi 2005;Yu et al 2011;Pi et al 2013).…”

“…1C) was made of 1.2 mm thick decorative face (upper) veneer, seven-layer core plywood, and 2 mm of poplar back (lower) veneer. According to a study conducted by Seo et al (2011), the thermal transfer performance of flooring is dependent on the material's thickness. As a result, all three types of engineered wood flooring possessed the same dimensions: 910 mm length, 125 mm width, and 15 mm thickness.…”

This paper explores the thermal conductivity of engineered wood flooring, which is widely used in world market. The effects of decorative veneer type and structure on the thermal conductivity of engineered wood flooring were studied. Four decorative veneer types and three different structures of engineered wood flooring served as test specimens. All samples were placed in a laboratory simulating a heating system environment, of which the temperature should be measured three times every five minutes. The temperature differences between the upper and lower surfaces were as follows: cherry > maple > birch > eastern black walnut. Three types of structures also showed differences in temperature changes, based on five-minute observations. The larger the decorative veneer's density, the higher the thermal conductivity, and the faster the heat transferred, meaning less heat was lost. The thermal conductivity of three-layer engineered wood flooring, with decorative veneer made of sawn wood, exhibited the best properties. The second best of the three samples was the three-layer engineered wood flooring with decorative veneer made of thick veneer and plywood. Finally, a multilayered engineered wood flooring performed the worst. The engineered wood flooring for use in heating systems should be chosen for its larger density of decorative veneer made of sawn wood.

“…Buildings account for 20% to 40% of the total energy consumption in developed countries (Pérez-Lombard et al 2008). In Korea, the energy consumption of buildings is more than 23% of the total energy consumption and, similar to other developed countries, this is increasing (Seo et al 2011). With the increasing economic standards among Koreans, concerns about human health and the environment have been escalating because of the increasing demand for a wide range of flooring products.…”

“…The importance of such awareness requires full responses at national, regional, and global levels (Forsberg and von Malmborg 2004;Frank 2005;Seo et al 2011). The growth rate of greenhouse gas emission per capita in Korea was the highest in the world from 1990 through 2004 (Chung et al 2009).…”

In recent years, research on low-energy building materials has actively progressed, with a growing interest in eco-friendly building. Strong interest has also been shown in the wooden flooring sector to improve the thermal conductivity of under floor heating systems. This study focused on improving the thermal transfer performance of radiant floor heating systems by enhancing the characteristics of the existing polyethylene underlay foam (PE foam). The thermal conductivity of the modified PE underlay foam (MPE foam) was increased by 48.1% compared with that of the PE foam. The theoretical heat flux was also calculated for the thermal conductivity, the results of which showed that the heat flux of the MPE foam was enhanced by 24.1%, compared with that of the underlay foam. To confirm the theoretical results, flooring systems were installed in the laboratory as a replica for the experiment. The velocity of thermal transfer for the laminated flooring used with the MPE foam was slower than the engineered flooring in which adhesive was used. However, the velocity of transfer was faster for the laminate flooring incorporating the PE foam. In addition, after the heating was switched off, the heat storage capacity of the laminate flooring with the modified PE foam was the highest among the tested samples.
