摘要

建築物的建造與運作佔了超過全球40%以上的二氧化碳釋放量，是造成全球暖化的元兇之一，而建築物空調的使用是重要原因。在台灣夏日艷陽照射在建築物外殼，太陽輻射熱持續傳導至室內，造成夏日用電量大增，也造成大量的CO2排放。外殼節能設計利用斷熱材料包覆建築物減少外界熱量侵入室內可以有效保溫、降低空調的使用，讓建築物在使用階段可以達到節能減碳的效果。
為深入瞭解建築物斷熱的節能減碳效果，本研究利用產品生命週期評估法建構建築物外殼斷熱之碳足跡計算方法與減量分析模式。本研究先以建築物理環境分析軟體Ecotect Analysis來比較建築物斷熱前後之耗能差異，接著再以生命週期評估軟體Simapro來具體計算建築物斷熱可以減少的環境衝擊，以及可以減少的排碳量。在2010年，在聯合國主導之京都議定書衍生的自願碳標準(Voluntary Carbon Standard，VCS)架構下，以建築物斷熱(Weatherization of Single and Multi-Family Buildings)作為方法學(methodology)所節省之碳量已被認可為有價值的碳權資產，可以作為國際碳交易的籌碼。本研究提供了客觀計算依據來預估台灣推動建築物外殼斷熱所能節省之排碳量與衍生的具體價值，可作為政府推動節能減碳政策之重要參考。

Construction and operation of buildings accounts for over 40 percent of global carbon dioxide emissions, and it is one of the main factors of global warming. Of all the factors, the use of air-condition is the most important item contributed to the emissions of carbon dioxide. In Taiwan, the fiery sun exposures the external walls of the building in the summer. The heat created from solar radiation transfers to the interior of the buildings continuously, causing significant increase in electricity consumption, further producing large amounts of CO2 emissions. Shell energy-saving design for buildings utilizes thermal resistance material which covers buildings to reduce the amount of external heat entering indoor. By doing so, effective insulation can be achieved and the usage of air condition can be reduced so that energy saving and carbon reduction effect can be reached during the building use phase.
To better understand the carbon reduction effect results from thermal break design. This study applies the product life cycle evaluation method to construct a carbon footprint calculation method and a carbon reduction analysis model for building envelope thermal break. At the first stage, the building physical environment analysis software, Ecotect, is applied to compare the energy consumption difference before and after implementing the building envelope thermal break. Then, life-cycle assessment software ,Simapro, is applied to calculate the specific environmental impact and carbon emissions reduction caused by the thermal break design.
In 2010, under the structure of the Voluntary Carbon Standard (VCS), a derivative of the Kyoto Protocol led by the United Nations, using building thermal break (Weatherization of Single and Multi-Family Buildings) as the method of carbon savings has been recognized as a valuable asset of carbon rights which can be used as a bargaining chip for international carbon trading.
This study provides an objective calculating basis in estimating the carbon reduction and other specific values while promoting the building envelope thermal break in Taiwan. It can be used as an important reference for the government while promoting energy saving and carbon reduction policies.
