本論文以台北某辦公大樓建築物作為研究目標,並且以EnergyPlus建築全能耗分析軟體(Whole building energy analysis tool)建立建築模型進行大樓整體耗能分析。該建案在設計階段就預期要申請LEED認證,從設計開端到施工採取整合導向式綠建築的節能概念設計,而此辦公大樓在HVAC(Heating, Ventilating, and Air Conditioning)系統上選用VRV(Variable Refrigerant Volume)多聯變頻空調搭配HRV(Heat Reclaim Ventilation)全熱交換器作為大樓之空調設備。由於本案為建設中之建築物,故本論文將收集建案設計資料,透過日後現場場勘核對設備安裝是否有進行變更,並修正其模擬結果,探討建案模型因空調系統及變更建材設計之設定參數不同所產生的能耗變化。 結果顯示,將VRV空調系統有無搭配全熱交換器進行比較,若將VRV空調系統搭配HRV全熱交換器之全熱回收換氣技術,在能耗上僅僅較單純使用VRV系統增加1.2%能耗。如將此棟大樓的空調設備更換成冰水主機,此空調能耗增加了2,528.19GJ,整體能耗影響增加了19.1%。而此建案使用了大量的玻璃帷幕外牆,在整體建築外殼窗牆比為0.7,若將建築外牆組成結構作變更,如使用輕型結構外牆(Light Exterior Wall)之整體能耗值為10,678.56 GJ,而與變更為中等結構外牆(Medium Exterior Wall)及重型結構外牆(Heavy Exterior Wall)相對於Light Exterior Wall之整體能耗值差異皆不超過0.1%。如變更玻璃材質及增設遮陽設置後,使用一般清玻璃材質對於原設計之低輻射雙層Low-e玻璃整體能耗約增加7.36%,若一般清玻璃無遮陽設備與一般清玻璃增設高反射能力窗簾相互比較結果顯示,一般清玻璃增設高反射能力窗簾之能耗值約能降低7.95%的能耗,而在低輻射雙層Low-e玻璃增設高反射能力窗簾相較於雙層Low-e玻璃無增設窗簾,約降低了0.98%的能耗。如將玻璃貼隔熱膜,單純使用3M清玻璃之整體能耗值為11,964.51GJ,在3M清玻璃貼上隔熱膜(IR65CLAR)較一般3M清玻璃之能耗值約降低了4.2%,而在3M清玻璃貼上隔熱膜(Silver 18)較一般3M清玻璃之能耗值約降低了8.5%,如將玻璃貼隔熱膜與原設計雙層Low-e玻璃相互比較,在3M清玻璃貼上隔熱膜(IR65CLAR)較原設計之雙層Low-e玻璃之能耗值約上升了7.4%,而在3M清玻璃貼上隔熱膜(Silver 18)較原設計之雙層Low-e玻璃之能耗值約上升了2.5%。
The study is taking a real office building in Taipei for the modeling example. And EnergyPlus, the whole building energy analysis tool is utilized to establish the energy consumption result of computer simulation model. The building was expected to apply LEED certification. From design to implementation, the energy saving concept of green building should be added. VRV system Inverter Air Conditioners with HRV on the HVAC system are required to be the air-conditioning equipment in the building. Because the building in this study is under construction, this study collect the data of the building during the designing stage. In order to check whether the equipment changes or not, modify the modeling results through the on-site inspection. We also discuss the changes of energy consumption caused by changing the parameters of air-conditioning system and differences of the building materials in this study. The results showed that compared with VRV system, VRV system which attached HRV increases merely 1.2% energy consumption.Due to the change of air-conditioning systems, the energy consumption gained 2,528.19 GJ, which is 19.1% more than the original overall energy. Furthermore, it shows that if the building changes the material and structure of the exterior wall, instead of using Light Exterior Wall, the whole energy consumption is 10,678.56 GJ. And compare with Light Exterior Wall, the diversity of Medium and Heavy Exterior Wall energy consumption is below 0.1%. After changing the material of glass and setting sunshade equipment, compare with the double layer Low-e glass, clear glass’s energy consumption increase approximately 7.36%. Moreover, compare with clear glass and clear glass with high reflect curtain, clear glass with high reflect curtain reduces 7.95% energy consumption. Compare with double layer Low-e glass, double layer Low-e glass with high reflect curtain reduces about 0.98% energy consumption. 3M clear glass’s energy consumption is 11,964.51GJ. And 3M clear glass be stuck the heat insulation film. IR65CLAR heat insulation film’s energy consumption reduces about 4.2% and Silver 18 heat insulation film’s energy consumption reduces about 8.5%. Comparison of glass with heat insulation film and double layer Low-e glass, 3M glass with IR65CLAR heat insulation film’s energy consumption is higher 7.4% and 3M glass with Silver 18 heat insulation film’s energy consumption is higher 2.5% than double layer Low-e glass
