The contents consist of the following 4 studies: 1) Surveys of various energy consumption of real existing buildings, 2) Heat protection on rooftops for reduction of cooling load, 3) Cooling trench under the basement for reduction of air conditioning load, 4) Practical conditions of energy saving buildings and effects of ESCO. The first, 1) is a study on detailed energy consumption in houses all through the year to examine the characteristics of energy use in houses and possibility of energy saving. The second, 2) is an estimation of reduction of cooling load, energy saving and cost-cutting for energy by thermal protection on rooftops from direct solar radiation that are weakest parts of cooling load based on a survey of a real existing building. The third, 3) is examination of the effect of cool trench that is called Earth tube in this study through a full-scale measurement in a building with an Earth tube to clarify its performance in subtropical Okinawa. The fourth, 4) is an evaluation of improvement of buildings for energy saving, especially ESCO projects, to examine its efficiency through some surveys. The targets of the surveys were various types of buildings, public, office, hotel, commercial, factory, school and hospital, except residential houses in Okinawa and in Hawaii to compare each other. The practical energy consumption and thermal environment in the buildings, awareness and actions of energy saving were surveyed in Okinawa and Hawaii.\nMain results from these researches are as follows: the most energy consuming factor in residential houses in Okinawa is hot water supply, while that in non-residential buildings is air-conditioning system. Therefore, energy saving in non-residential buildings is almost the same meaning as reduction of air conditioning, especially cooling load in subtropical zones. For this purpose, thermal protection on rooftops and ESCO projects were found effective to achieve every saving, although the Earth tube was not. Awareness of energy saving was high both in Okinawa and Hawaii. However, Energy saving actions in Okinawa were basically occupants’ voluntary behavior, while those in Hawaii depended on the energy efficiency of building equipment and appliances. These conclusions are significant basic documents for the realization of energy saving buildings besides net Zero Energy Buildings (ZEB).","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学"},{"subitem_1522300295150":"en","subitem_1522300316516":"University of the Ryukyus"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617187087799":{"attribute_name":"Dissertation Number","attribute_value_mlt":[{"subitem_1551256171004":"乙第58号"}]},"item_1617187112279":{"attribute_name":"Degree Name","attribute_value_mlt":[{"subitem_1551256126428":"博士（工学）","subitem_1551256129013":"ja"}]},"item_1617187136212":{"attribute_name":"Date Granted","attribute_value_mlt":[{"subitem_1551256096004":"2022-03-18"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-06-24"}],"filename":"rikoron58abstract.pdf","filesize":[{"value":"532 KB"}],"mimetype":"application/pdf","url":{"objectType":"abstract","url":"https://u-ryukyu.repo.nii.ac.jp/record/2019336/files/rikoron58abstract.pdf"},"version_id":"136d21d4-2ea4-4f7a-b673-dc7036584647"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-06-24"}],"filename":"rikoron58review.pdf","filesize":[{"value":"374 KB"}],"mimetype":"application/pdf","url":{"objectType":"other","url":"https://u-ryukyu.repo.nii.ac.jp/record/2019336/files/rikoron58review.pdf"},"version_id":"bfe682cf-2649-479a-b68f-861125abc61c"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-06-24"}],"filename":"rikoron58text.pdf","filesize":[{"value":"47.5 MB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2019336/files/rikoron58text.pdf"},"version_id":"fe385bb8-c3da-4cf9-8cec-e21eeb81173c"}]},"item_1617944105607":{"attribute_name":"Degree Grantor","attribute_value_mlt":[{"subitem_1551256015892":[{"subitem_1551256027296":"18001","subitem_1551256029891":"kakenhi"}],"subitem_1551256037922":[{"subitem_1551256042287":"琉球大学","subitem_1551256047619":"ja"}]}]},"item_title":"A Study on Thermal Environment and Energy Consumption of Buildings in Subtropical Okinawa","item_type_id":"59","owner":"8","path":["1642838161450","1642838411479"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-06-24"},"publish_date":"2022-06-24","publish_status":"0","recid":"2019336","relation_version_is_last":true,"title":["A Study on Thermal Environment and Energy Consumption of Buildings in Subtropical Okinawa"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2022-06-24T04:25:58.476636+00:00"}
