摘要
本研究主要探討個別空調使用行為，試圖瞭解使用者如何間歇採用空調及自然通風以維持室內熱舒適度。本研究利用長期監測台南地區政府機關、中小企業辦公室，以及住宅主要使用空間「客廳、主臥室、次臥室」等52個建築空間的個別空調使用行為，並藉由一般國際間廣為接受的「自然通風環境之可接受舒適度範圍ASHRAE Standard 55_2004」來檢討台灣地區住宅與辦公室的空調使用行為。
本研究實際監測分析發現，辦公室個別空調使用時間落在3月~11月，而夏季公部門空調使用率幾乎為私部門的2倍。住宅主要空間個別空調使用率方面：主臥室使用率最高，其次是次臥室，再來是客廳。
室內熱適應性開機操作溫度行為方面：公部門辦公室為28.36℃最低，其次是私部門辦公室為30.09℃，住宅居家為30.76℃，顯示私人空調使用較公部門節約。
本研究並將每月開機平均開機溫度與「ASHRAE Standard 55_2004自然通風可接受舒適度範圍」加以比對，發現公部門辦公室全年各月之開機溫度皆落在90%滿意區間內，顯示公部門辦公室常在尚可自然通風的溫度條件下即開啟空調。私部門春秋季開機溫度落在90%滿意內，6~9月開機溫度落在80%滿意度上限邊緣，顯示私部門辦公室於春秋季有少開空調的潛力。住宅各空間開機溫度皆落在自然通風環境熱舒適範圍曲線圖80%滿意度上限邊緣，顯示台灣住宅空調使用的節約程度，約接近ASHRAE Standard對於自然通風環境的建議。
本研究分析辦公、住宅建築在夏季個別空調使用行為與建築室內通風之關係：公部門辦公室不論是室內空間通風良好或不佳，空調使用率皆高。私人帷幕辦公大樓室內通風不良，空調使用率高。私人公寓辦公室通風良好，但各案例間空調使用率差異極大。私人透天辦公室縱深越長，通風不良，空調使用率偏高；而縱深越短則通風良好，空調使用率較低。住宅案例通風皆屬良好，然而各案例之間空調使用率差異頗大，故本研究推估，住宅空調使用之差異多來自使用習慣，而非住宅室內通風之優劣。

Abstract
This study was mainly on exploring individual air-conditioning behavioral pattern, trying to understand how users intermittently utilized with air-conditioning and natural ventilation to maintain indoor thermal comfort. This study monitored the individual air-conditioning behavior of 52 building spaces which including the government agencies, SME offices, and residential spaces (living rooms, master bedrooms, and second bedrooms) for a year, and explained the individual air-conditioning using patterns of the residence and office in Taiwan. Besides, the acceptable operative temperature range for natural conditioned spaces quoted from “ASHRAE Standard 55-2004” was also used to ensure above statement.
The actual monitoring and analysis of this study found that the individual air-conditioning usage of the offices mainly started from March to November. And the air-conditioning utilization rate of public sector is almost 2 times than private sector during summer.
For indoor thermal adaptability on operating temperature: the office of the public sector contains 28.36 ℃ as the minimum temperature, followed by the office of the private sector as 30.09 ℃, and 30.76 ° C for the residence. Those data showed that the air-conditioning usage of private sector is less than public sector.
In this study, the average operating temperature per month was compared with the acceptable operative temperature range for natural conditioned spaces that quoted from “ASHRAE Standard 55-2004”, and this study found that the operating temperature for each month throughout the year in offices of public sector falls in the range of 90% satisfaction. This showed that chillers were often used in those offices under natural ventilation conditions. On the other hand, the operating temperature of the private sector falls within the range of 90% satisfaction during spring and autumn, while the operating temperature falls to the edge of upper limit of 80% satisfaction from June to September, showing the offices of private sector have potentials in using less air conditioner during spring and autumn. The operating temperature for the residence is fall to the edge of the upper limit of 80% satisfaction for the curve of thermal comfort range in natural ventilation environment, revealing the air-conditioning usage of Taiwan residence was approximately similar to the ASHRAE Standard recommendations for natural ventilation.
The relationship between indoor ventilation and behavior of individual air-conditioning for official and residential buildings during summer was analyzed in this study. Public-sector offices, whether poor or well ventilated, their air-conditioning utilization rates are high. All curtain-wall private offices are poor ventilated, and their air-conditioning utilization rates are high. Apartment offices are all well ventilated, but their air-conditioning utilization rates vary greatly among each individual case. Housing offices with long room depths are poor ventilated, and it causes high air-conditioning utilization rate. Conversely, the short-room-depth ones are well ventilated, and the air-conditioning utilization rates are low. All residential cases in this study are well ventilated, but air-conditioning utilization rate is considerably varied among each cases. Therefore this study estimates that the differences in air-conditioning usage for residence are mostly from different using habits, rather than its pros and cons of indoor ventilation.
