一、研究緣起
在氣候環境劇變與全球能源危機情勢下，如何有效應用 BIM 與其相關的技術進行建築生命週期的資訊管理、與建築效能評估，以達到提升營建效率、提供降低建築能耗的解決方案，成為當代營建相關產業指標性的議題。
二、研究方法及過程
本研究提議導入臺灣 Green BIM，作為建築環境模擬及綠建築設計之評估操作機制，以達到環境永續發展之目的。以”建築物能耗評估分析”與”設計優化”為例，本研究深入探討 Green BIM 的實作流程。
Green BIM 的研究範疇包括：(1) 建築資訊建模 BIM、(2) 建築效能分析 BPA、(3)永續建築設計。
臺灣 Green BIM 強調從設計之初便以 BIM 建築資訊建模作為基礎工具，因應臺灣在地化的氣候條件，進行 BPA 建築效能分析，透過”設計”、”評估”的決策循環，產生符合環境效益的最適化的設計方案，最終達到追求環境永續發展的目的。根據文獻回顧與案例分析，本研究選擇適當的 BIM 與 BPA 工具，針對專案進行實作，並記錄設計與評估程序，印證理論與方法的可行性。
研究團隊並且舉辦 Green BIM 綠色營建應用研討會，分別就 Green BIM 施工營造、綠建築設計、審照自動化、產業聚落等向度，進行可行性應用的探討，並於期中報告後舉行專家座談，以作為研究報告修正與未來應用的重要依據。
三、重要發現
Green BIM 在永續建築設計上的應用成為當代重要的研究議題。Green BIM 的應用可達成效益如下：
(1) 利用 BIM 操作過程的效率與精準特性，達到節省成本(縮短時程、減少錯誤)的目的。
(2) 設定節能減碳之設計目標，如初始階段的物理環境評估與省能對策、有利於綠色的構造材質設計，以及綠建築指標計算模組、後續營運階段的智慧能源監控等。
(3) 透過 BIM 技術模型化評估、資料庫運算分析與四維時間管理之能力，與綠建築評估指標的運用結合，以達綠建築生命週期生態效益的”Green”目的。
四、主要建議事項
根據研究發現，提出下列具體建議：
(1) 採行 Taiwan GREEN BIM 基礎的”節能評估指標”
(2) 在”日常節能指標”的認證上，Green BIM 與 EEWH 並行
(3) 結合綠色建築指標評估、邁向 BIM 基礎的整合性設計決策流程
(4) 建立助益於”多元決策”的綠色建築指標體系
(5) 政策鼓勵、其它的更高標準的”能源目標”

1.Origin
Facing the climate change upheaval and the global energy crisis situations, How to effectively apply BIM technology andits related technologies to process building lifecycle information management and building performance analysis, in order to enhance construction efficiency and reduce building energy consumption, become index of topics in contemporary construction and its related industries.
2.Method and Procedure
This study suggests applying“Taiwan Green BIM”, as a building environmental simulation and an assessment mechanism of Green building design, in order to achieve the purpose of building energy efficiency and reduce carbonemissions.
The research scopes of “Taiwan Green BIM” include：(1) Building information modeling (BIM), (2) Building Performance Analysis (BPA), and (3) Sustainable building design.
From the beginning of the design, Taiwan Green BIM emphasizesto apply BIM based BPA, to execute the decision making circle, including design, analysis, and assessment, in order to produce optimal design solutions tosatisfy with environmental efficiency and to achieve the purpose of environmental sustainable development.
According to the literature review and case study, this research selects appropriate BIM and BPA tools, and implements projects to record design and assessment procedure, in order to confirm feasibilities of Green BIM theory and method.
Research team conducts the applications of Green BIM seminardiscussingfeasibilities
ofGreen BIM. The issues of the seminarinclude Green BIM construction,the applications in Green building design, and automation in reviewing building permits, Industry settlementand Society. And the research team plans to hold the expert symposium in order to accept experts’ opinions as important foundations of reports amended and the studies of future Applications.
3.Key Findings
Green BIM applications in sustainable building design become important contemporary
research agenda. Green BIM applications can achieve the following benefits：
(1)Usingthe efficiency and precision characteristics of process of BIM operation,in order to achieve cost savings (shorter duration, fewer errors)
(2)Setting the design goals for carbon reduction, such as the physical environment assessment and the initial phase of energy-countermeasure, which are conducive to the development of green construction and materials, green building indicators and their computing module, subsequent operational phase,smart energy monitoring. (3)Using BIM-based BPA, database analysis and computing capability of four-dimensional time management, to integrate Green building indicators, in order to achieve objective of the green building eco-efficiency during whole building live cycle.
4.Recommendations
Base on this research, The specific recommendations include：
(1)Adopting Taiwan GREEN BIM-based energy saving performance assessment indicators
