古蹟暨歷史建築於修復過程之室內環境品質策定比較探討－－以臺南縣金唐殿為例

Comparisons on the Indoor Environment Measurement of the Historic Building during the Renovation Steps: Jin-Tang Temple in Jia-Li Town as Illustration

無論是從文化保存抑或永續健康的觀點而言，如何將老化的古蹟暨歷史建築經由修護再利用 _而能重獲新生，已是普世共通的價值。為釐清古蹟暨歷史建築物於修復過程中，室內環境品質對 _室內人員健康影響，本研究採自動連續量測法（ASM）測定，現場量測項目包括：CO、CO2、 _PM10、風速、溫度、黑球溫度、相對濕度、噪音、照度、PMV & PPD、換氣效率、甲醛與 _TVOC ，測點安排除於室內空間外，亦同步進行外氣測定。測定期程主要配合金唐殿所進行的修復計畫 _，於修復過程之前、中、後共計進行四次。實測結果得知，修復後甲醛與 _TVOC 濃度明顯升高， _但無法排除拜香之影響及推估施工之貢獻量，若長期暴露於此濃度下，可能對室內活動之人員產 _生顯著之健康影響，建議於修復工程進行之同時，可考慮採用機械輔助通風或除污裝置。再者， _傳統建築屋架有助於熱浮力通風，須留意自然對流路徑，以維持室內環境品質。 _

Whether from the viewpoint of the cultural conservation or the sustainability and occupants’ health, it is an valuable issue how to renovate an antiquated historic-building. It is, therefore, necessary to identify the health benchmark of the indoor environment quality during the renovation period. Fourteen factors, CO, CO2, PM10, velocity, air temperature, globe temperature, relative humidity, sound pressure level, illumination, PMV, PPD, air-exchange rate, fomaldehyde and TVOC were adopted in the field measurement of this study by the auto-success method (ASM). Results showed that the Indoor concentrations of fomaldehyde and TVOC were increased obviously during and after the renovation period. Increasing air-exchange rate combined cross-ventilation with stack effect could dilute indoor pollution. It should be necessary to the IEQ consideration in renovation period.
