Knowing the relationship between ground loads and fluid temperature in boreholes is crucial for designing geothermal systems. The purpose of this study is to add temperature information to the "rules-of-thumb" currently being used, for example 30 to 40 W per meter in depth, by statistically analyzing field operating data of actual boreholes throughout the country. Herein, first, a sizing equation is proposed for boreholes, which takes into consideration of heat extraction/injection and the ground temperature deviation. Next, through experimental operation with an existing ground source heat pump system, these two parameters are shown to be effective for both the evaluation and the design of boreholes independent of the regions in which they are used.

To improve the energy efficiency of buildings, energy efficient equipment and facilities are utilized. However, despite their use, buildings do not perform as well as anticipated. Therefore, commissioning the equipment and facilities and evaluating the resultant performance are necessary for improving the target building's performance. The primary goal of this research is to verify and optimize the performance of the air-conditioning system within buildings. This paper presents field experiment measurements and evaluation results of the air-conditioning system in an existing building. The experiment evaluated the dependence of the cooling energy on the chilled water temperature. We found that by changing the temperature of chilled water from 4.5℃ to 8.7℃, the system's coefficient of performance improved by 13%, while the cooling capacity was found to be sufficiently high.

In the cases of terrorism acts performed using nuclear, biological, or chemical weapons, prompt decontamination and removal of contaminants from the human body become critically important tasks during rescue operation. The overarching objective of this study was to develop a decontamination system based on forced convective flow, which enhances the desorption or detachment of the contaminants by increasing the mass transfer coefficient from the human body surface. This paper (part 3) introduces a prototype model of a wind decontamination system (WDCS) and reports on the results obtained from an experimental investigation of its efficiency for gas- and liquid-phase contaminant removal from a clothed human body. SF_6 gas and pure water were selected as the gas- and liquid-phase contaminants, respectively, in a computational fluid dynamics simulation. The decontamination efficiency in the case of the gas-phase contaminant was confirmed to surpass a value of approximately 90% within a 30-s decontamination time duration.

In the recent years, the green movement has spread over our society. Some research works provide evidence on the economic value of the certification of "green buildings," However most such research works employ statistical techniques and social scientific methods. In this study, the direct capitalization model of a case study building was developed. In addition, the building energy simulation model was developed to quantify the energy consumption of the building. For the combined direct capitalization model and energy simulation model, the value of the energy conservation technology used in the building was evaluated. The model revealed that 13% primary energy reduction was equivalent to a 0.11% capitalization rate reduction.
