摘要

台灣地處亞熱帶氣候區，夏季高溫的氣侯條件會影響室內生活環境，現今公共建築在外殼材質的常使用透視性玻璃材質，雖然增加景觀視野的通透性，同時也引入太陽輻射熱進入室內，造成室內環境的熱度提升，尤其在提供大量遊客服務機能的遊客服務中心，也需滿足室內環境舒適度及節能的需求。因此本研究採「數值模擬」及「現場實測」二種方法，相互比對及分析日照時數、溫度分佈、熱量平衡及空間舒適度之實際狀況。研究結果顯示，不同建築外殼材料，因熱阻及導熱係數的不同，加上日照的方向及時間長短，都會影響熱傳遞到室內的狀況，使的室內的溫度產生變化，而影響到室內環境舒適度。室內模擬輻射溫度範圍在21~29℃，若不啟動無空調設備之狀況下，熱舒適指標（PMV）平均值為2.71PMV，不舒適指標（PPD）更高達93.09%，未來室內場館的舒適性會影響到遊客的休憩行為。

Taiwan located on subtropical climate zone. The weather is hot, rainy and humid, coupled with the public buildings in the shell material of high perspective of design techniques, but also hope to meet a comfortable indoor environment and energy needs, so in this study, the shape of the actual situation and provide a lot of new material tourist service functions visitor center study, the use of ＂numerical simulation＂ and ＂field test＂ to each other than the right, analysis of sunshine, temperature distribution, heat balance of comfort and space. The results showed that the different building envelope materials, due to different thermal resistance and thermal conductivity, plus the direction and duration of sunshine, will affect the heat transfer to the interior of the situation, so that the indoor temperature to produce change, and affects the indoor environment comfortable degrees. Indoor simulated radiation temperature range 21 ~ 29℃, thermal comfort indices （PMV） with an average of 2.71PMV, discomfort index （PPD） as much as 93.09%, comfortable indoor environment will affect the behavior of tourists sitting, really hot environment exists in this space. Also due to different spatial design different orientations, different spatial use patterns will affect both the comfort of the indoor environment.
