Detail survey of energy consumption of combined elementary and junior high school with other public facilities

Abstract

Combined elementary and junior high school is increasing in recent years. In this research, the energy consumption of a combined elementary and junior high school with other public facilities was examined in detail, and the energy consumption tendency and the influences of other public facilities were analyzed. The results are shown as follows. 1 The energy consumption of combined elementary and junior high schools increased after unification in all schools in Shinagawa Ward. 2 The power consumption of the school building of Saturday and Sunday were more than half of that of the weekday. As for this factor, the influence of an integrated learning facilities in the school building and operation of 24 hours ventilation in night-time was guessed. The gas consumption for GHP occupied about two-thirds of the annual total gas consumption in the school building. 3) The power consumption of the nursery school and pool building were occupied by underground heat pump for heated pool warming and pool filter device approximately 50% in the year. The gas consumption of nursery school and pool building were mostly occupied by boilers, which were used for hot water supply and heating of the nursery school, and shower, heating and warming assistance of the pool. 4 As for the annual comparison of the primary energy consumption per floor space, the nursery school and pool building was about 4.5 times of the school building. It is shown that the energy consumption of the nursery school and pool building accounted for about 40% of whole school A building. 5) As a result of having estimated the energy consumption of other public facilities which is not included in the general elementary and junior high school, other public facilities accounted for about 45%. The energy consumption per floor space of school A building except these other public facilities is about only 9% larger than average conventional elementary and junior high school. As above, when the energy consumption trend of such school facilities is evaluated, consideration of the influence with other public facilities is necessary. In addition, it is believed that appropriate setting of the operation schedule of the ventilation equipment and appropriate setting an air conditioning area and temperature are important.
