Making possible experiments of actual scale, the Airflow Laboratory is among Japan’s largest laboratories. With it, experiments on the air-flow characteristics of large spaces inside buildings can be conducted at actual dimensions, or those close to them. In terms of the space available for conducting experiments, ceiling height can be altered from 2.2 to 11.0m. In addition, the laboratory is surrounded by cold-and hot-water panels, with guard rooms above and below, enabling accurate control of indoor surface temperature. Experiments conducted here include the investigation of large-space air-conditioning methods and the verification of improvements in airflow simulation accuracy. |

The Environment Simulation Room is composed of an open-air room, a mock living room and an observation space. The open-air room has lights of nearly the same wavelength range and intensity of sunlight and is equipped with a solar simulator that enables the incidence angle to be adjusted. In addition, as temperature and humidity can be set within the ranges of -10 to 40 degree C(dry-bulb temperature) and 30 to 80%(relative humidity), all kinds of outdoor environments found within Japan can be reproduced. Additionally, the mock living room is structured to enable modification of ceiling height, spatial and temperature conditions on the top and bottom and open-air partitions. Thus, these two rooms facilitate the creation of various indoor environmental conditions. Here, experiments are conducted to evaluate what how people are affected by various air-conditioning systems, living environments and environmental factors. |

The Acoustic Experiment Laboratory is composed of an anechoic room and a reverberation room. With vibration-proof equipment installed on top of the footing beams on the outside and a structure of reinforced concrete on the inside, the building has a flexibly supported duplex structure. In keeping, not only is the effect of ground vibrations reduced but external noise is nearly entirely blocked out and external thermal influence can be eliminated. The anechoic room is a free sound field of 7.8m x 7.8m x 7.8m. By sliding the movable reflective floor, a hemi-freefield can be created. The anechoic and reverberation rooms can each be used on their own or by using the openings on the partitions, the functions of both rooms can be used at the same time. Experiments conducted here include those on noise from equipment and machines, environmental noise, facility maintenance and control using sound quality and vibration analysis, and the sound environments of living spaces. |

The Large-scale Experiment Laboratory is a giant space with 10m in effective height and equivalent to a 3-story building. Here, trial manufacture and testing can be done on various types of equipment at their original size and practical scale. This laboratory is equipped with various utilities used in experiments. |
