摘 要 本研究針對台灣地區公寓大廈住宅社區公共用電解析，共抽取17 個社區樣本、3,684 戶，透過 現場調查及電力資料蒐集，並將公共用電進一步分為「大公共用電」、「小公共用電」與「停車場用 電」等項目解析。其中大公共用電量與「實設空地面積」及「含空調的社區空間面積」有關，小公 共用電與「梯棟之服務核配置」有關，停車場用電則與「停車場面積」有關。本研究最終提出2 條公共用電預測式，並將其與實際公共用電作差異性分析，從「各型態使用面積」預估公共用電時 相關係數為0.977，從「土地開發強度」預估公共用電時其相關係數為0.954，均具有相當的精準性。 本研究結果除了於設計階段進行用電預估，若加上既有文獻之公寓大廈私有用電部分，可整合成未 開發住宅土地於開發後的用電全貌，可提供未來都市整體能源政策之參考。

ABSTRACT This research investigated the electricity consumption for public spaces in 17 condominiums with 3,684 households in Taiwan. Through on-site auditing and data gathering, public electricity consumption could be analyzed for three parts. The results showed that outside public electricity consumption related to vacancy area and area with air condition, inside public electricity consumption related to allocation of service core, and public electricity consumption in parking space had relationship with its area. 2 regression equations were developed to predict total public electricity consumption. When all kind of public space areas were concerned, the coefficient of relevance was 0.977. When development intensity was taken into consideration, the coefficient of relevance was 0.954. These results and previous research about electricity consumption for household of condominium can be combined as the initial estimation for building development and the reference for urban power supply as well.
