摘要

台灣地區在能源的使用層面上，長久以來都大量依賴高污染排放之化石能源，因此溫室氣體排放量居高不下。因為化石能源的再生週期相當久，幾乎可以視為不可再生的能源，所以如何降低對於化石燃料的依賴度，去發展適合台灣的自然再生能源將是邁向永續的一大重點。
本研究之標的以現實建築物之能源使用統計資料為參考值，針對標的所需之空調及熱水能力進行換算，共分為7個情境，其中Case1及為標的原始之統計資料，其餘Case皆為假設情境，評估結果為Case 2a(全部空調皆替換為本研究之研究產品)在能源投入、CO2減少排放量及使用階段能源費用等項目表現最佳，而Case 3則在各假設情境中表現最差，但相對於Case1而言，在CO2減少排放量、能源投入及使用階段能源費用等亦有相當程度之優勢，CO2排放方面則較Case1為多。與Case1相比較，使用階段之能源投入之減少量約在69,747~123,082GJ之間；使用階段之CO2減少排放量則在2,429~11,662Mt之間；使用階段能源費用節省量為5,260~8,680萬之間。償付期方面，本研究只針對全使用本研究選定之地源熱泵空調機組之Case2、Case 2a及Case 2b作探討，能源償付期分別為0.12年、0.10年及0.16年；排放償付期則為0.08年、0.10年及0.12年。

Taiwan depended on fossil fuel as its main using energy for a long time, resulting the Greenhouse gases remained a huge number, and the regeneration cycle of fossil fuel was very long time, almost could as it was a non-renewable energy, so there is a problem how should we reduce the demand of fossil fuel, and developing the appropriate energy of natural resource will be a important step of sustainability with Taiwan.
This research’s target referenced the energy using statistics value of real exist building, calculated the target’s carrying capacity of air conditioning and hot water, there are seven cases in research, the case 1 is target’s original statistics value, the other are scenarios, the result of the case 2(all the air condition get exchanged with GSHPs)have the best performance with the energy input, reduction of CO2 emission and the energy costs in using phase, Otherwise the case 3 is the worst in every scenarios, but comparing with the case 1, it’s still has a nice performance and advantage, but the CO2 emission is more than the case 1. To compare with the case 1, the ranges of reduction of energy input in using phase is between 69,747~123,082GJ; the ranges of reduction of CO2 emission in using phase is between 2,429~11,662Mt, the ranges of energy costs in using phase is between 52~86M. The Payment of energy with the case 2, case 2a and case 2b are 0.11y, 0.10y, 0.16y; The Payment of CO2 emission are 0.08y, 0.10y, 0.12y.
