page： 33-36 2015.11

Language：Japanese Publishing type：Research paper (scientific journal)

We investigated psychological responses of students in a lecture room to examine whether indoor environment was kept well with all-air induction radiant air-conditioning system in winter. We carried out the questioner survey twice at the start and end of lecture to avoid disturbing the lecture. The results showed that the ratio of the comfortable side ("Neutral" - "very comfortable") was more than 80% at the end of lecture, although the room temperature at 600mm above the floor rose 2.0-3.4ºC in 90 minutes from the lecture start to end. Also, from the relationship between SET* and psychological responses (satisfied, appropriate and comfortable sensation), it was suggested that more than 70% of students felt the condition of lecture room appropriate as the learning environment, if the room temperature would be controlled as SET* targeted 25.2ºC and 26.8ºC at the start of 1st class and 3rd class, respectively.

Commissioning of performance on Energy and Environment of Urban Style Eco-Campus, Part4 Evaluation on the effects of cool breeze from an urban large-scale park Open Access

page： 361-364 2015.9

Language：Japanese Publishing type：Research paper (scientific journal)

By the cooling effect of trees in the park, the air temperature is usually to lower than that in built-up areas. The targeted campus has been planned to introduce cool breezes form an urban large-scale park as one of the energy-saving techniques. To evaluate the cooling effect, the measurements and CFD simulations were carried out. This paper, the cooling effect by the urban large-scale park was quantitatively discussed.

page： 349-352 2015.9

Language：Japanese Publishing type：Research paper (scientific journal)

Meijo Koen Campus of Aich Gakuin University introduces various advanced technologies to offer comfortable learning field and achieve a low carbon campus. To realize this target, setting of appropriate target and condition at planning phase and optimal design considering sufficiently how to use the facilities and building thermal load are required. At the same time commissioning of performance is indispensable for the system to show an expected potential. Under above mentioned background, the energy consumption, performance of heat source system and secondary side system and the indoor/outdoor environment are analyzed in this study. In this paper, energy consumption and CO2 emission of whole campus and performance of central heat source system for one year after beginning of operation were presented.

Commissioning of performance on Energy and Environment of Urban Style Eco-Campus, Part3 An Analysis and Improvement of Air Movement through the Stairs in the Library during Heating Period Open Access

Kento MORI, Teruyuki SAITO, Satoru IIZUKA, Masaya OKUMIYA

page： 357-360 2015.9

Language：Japanese Publishing type：Research paper (scientific journal)

We investigated indoor thermal environment and air movement through the stairs in the library with all-air induction radiant air-conditioning system in winter. The results show that hanging partition wall, shielding plate and decrease of exhaust air at the 2nd floor restrain the rise of heated air from the 1st floor to the 2nd and improve the vertical temperature distribution. In addition, it is necessary to decrease the fall of cold air into the downstairs at the same time.

page： 353-356 2015.9

Language：Japanese Publishing type：Research paper (scientific journal)

We investigated psychological responses of students and thermal environment in a lecture room with all-air induction radiant air-conditioning system in summer. The results show that the rate of vote in hot and uncomfortable side decreased, although room temperature rose 0.8-1.4oC for 90 minutes of a class. The rate of vote in the appropriate side becomes more than 70% if the room temperature is controlled from 24 to 26oC in the morning classes and is controlled from 25.5 to 26.5oC in the afternoon classes.

A Study on the Method of Window Opening to Use Cross Ventilation Efficiently in Housing Open Access

Sayako Kishi, Teruyuki Saito

page： 73-76 2014.12

Language：Japanese Publishing type：Research paper (scientific journal)

This paper aims to suggest a pattern for opening windows to keep the indoor thermal environment acceptable by cross ventilation in summer. Using the ratio of opening area on south and north side Ss/(Ss+Sn) as the parameter, the influence on thermal environment is evaluated by thermal and airflow network model NETS. From the subjective experiment conducted in summer 2013, 80% of subjects could accept the indoor thermal environment when the value of PMV was below 1.67 under the condition of cross ventilation, then this value is used as the upper limit to use cross ventilation. The results of NETS show that cross ventilation rate is influenced by Ss/(Ss+Sn) though the ratio of Ss+Sn to floor area is fixed, and cross ventilation rate calculated on whole housing is maximum at 50% of Ss/(Ss+Sn). Then, we suggest that the appropriate pattern for opening windows makes the value of PMV decrease. In summer, if occupants use cross ventilation in case of PMV below 1.67 and air conditioner in case of PMV over 1.67, it is possible to shorten the time of using air conditioner 1 hour in a single room at the opening pattern of Ss/(Ss+Sn)=61% from Ss/(Ss+Sn)=18%.
