建築生命週期能源使用量與形體參數之研究─以台中市辦公類建築為例

Study on Energy Consumption and Fparameters of Building Life Cycle Taking Taichung Office Building as an Example

本研究旨在探討建築形體與建築生命週期能源使用量之關係，採用形狀因子（值）理論、形體係數（S／V比）、開口率及建築外殼耗能量之內外周區等理論；以台中地區的辦公類建築作為參考案例，以相同體積設計出六個不同形體的方案，三種開口率之模擬樣本；採用BIM平台中的Autodesk Revil軟體進行能源模擬。在整個建築生命週期中，評估不同方案對電力使用及能源成本的影響，模擬後的結果採用SPSS進行統計分析。結果發現，不同的建築形體，對電力使用及能源成本呈現顯著性差異，在相同條件下，其中以細高型式建築能源使用量最高;而且較大的開口率亦不利於節能設計。

The purpose of this study was to explore the relationship between the energy consumption and form parameters of building life cycle, by the theory of shape factor (f-value), the form coefficient (s/v) theory, opening ratio in building, and the perimeter area of ENVLOAD theory. Six different shapes with the same volume and three opening ratio of samples were designed by using the office building of Taichung as the example. REVIT software was used to simulate the impact of different schemes on life cycle and evaluate energy consumption and energy cost. The data were statistically analyzed by SPSS software.Our results show that the significant differences were found between power usage and energy costs in the different building shapes. Among these, the shape of high-rise type building cost the highest energy consumption. Moreover, large opening ratio of building is not conducive to energy saving.
