辦公空間屬高人員密度之工作環境,室內空間與設備若缺乏完善規劃,人員密度差異所產生的熱蓄積直接影響室內熱環境。因此本研究目的擬探討台灣都會區空調型辦公室最佳熱舒適環境,並提出空調設定溫度與開啟時機。 本研究於2011年至2012年熱天環境,針對台北、台中、高雄空調型辦公室進行現場調查,共取得56家辦公室樣本之室內外物理環境參數與空間使用現況。研究結果顯示,台北市人員舒適溫度約落在25.3℃ ET*、台中市約落在26.1℃ ET*、高雄市約落在25.5℃ ET*,此外,根據複迴歸分析發現,事務型辦公室之舒適溫度受天花板高度影響,而服務型辦公室受人員平面密度影響。本研究提出了事務型與服務型辦公室之迴歸方程式,在空調設定溫度為27℃時,推估結果能減少6%的能源浪費且提供舒適的工作環境。此結果可做為空調控溫之參考,並提出節能設計建議以達到節能效益。
Temperature setting of air-conditioned office is related thermal comfort of occupants and energy saving. This study focuses on suitable thermal emviromements in air-condition office. Field surveys were conducted 481 occupants in 56 offices (classified into affair offices and service offices) during the summer time in three metropolitans in subtropical Taiwan. The results show the standard effective temperature (ET*) in the offices in metropolitans, Taipei (north), Taichung (center) and Kaohsiung (south) at 25.3℃, 26.1℃, and 25.5℃. The comfort temperature in affair offices relates with the ceiling height, and in service offices relates with the planar density of occupants by multiple regression analysis. The setting temperature in affair offices and service office follows the analysis result in regression equations. The temperature of air-condition sets at 27 ℃ in order to conserve 6% energy(based on 26℃ by government recommends). These results provide a reference of temperature setting to achieve the energy saving.
