ActivitiesAssociate Professor Hiyama wins “The Society of Heating, Air-conditioning and Sanitary Engineers of Japan Technical Paper Award (academic papers division)” 2014.05.21

  Kyosuke Hiyama, Associate Professor (tenure track) of Architectural and Design Engineering, Information Science and Design Engineering at the Graduate School of Science and Engineering (engineering), has won the 52nd Society of Heating, Air-conditioning and Sanitary Engineers of Japan Award (academic papers division), and was presented with the award at a commendation ceremony after the general meeting of the Society of Heating, Air-conditioning and Sanitary Engineers of Japan held on May 13. The award was given in recognition of a series of research achievements entitled “Thermal Environment Simulation Using Heat Response on Static Flow Field.” Here, “heat response” refers to time-dependent thermal effects on each location of a given space by heat generated in that space. This research defines the space within a room where the air flow is controlled by air-conditioning etc. as a “static flow field,” and applies the heat response to such a space to the analysis of the indoor thermal environment of a building and to energy consumption. In other words, this research applies computational fluid dynamics (CFD) analysis techniques to develop 3D simulation technology which takes into account the spatial distribution of an indoor environment. In the series of research achievements, the simulation results were compared with experimental results and the validity of the method was verified. The research results above were summarized in four articles published between 2009 and 2012, and were published in the journal of the Society of Heating, Air-conditioning and Sanitary Engineers of Japan. The award was given in recognition of these achievements. In general, when a new structure or principle is designed in the course of device development etc., its effects are verified by experiments. However, in fields such as construction, where many huge and one-off, made-to-order materials are involved, experiments are not easy to conduct, and thus it is necessary to predict without experiments whether the planned facilities and structures will have the expected effects. The technology with the power in such cases is computer simulation. The technology developed here will become a basis for evaluating energy-saving building designs which use indoor spatial temperature distributions, such as task-ambient air-conditioning (technology which conditions air only where necessary, for example only around people), demand for which has been increasing in recent years, and high-temperature exhaust systems which use atriums (blowout structures). The expectations for energy saving in the field of architecture are high, as the technology offers a way to solve global environmental issues which have been growing increasingly more serious in recent years. Including this research and development project, the research group of Associate Professor Hiyama is expected to make a contribution to the further development of technologies to solve these issues. News of the presentation of the award was reported in the newspapers, along with details on the research conducted in Associate Professor Hiyama’s laboratory. (Ube Nippo on May 29, 2014)
