為瞭解獲得綠建築標章建築與一般建築建造成本之間差異，以北、中、南三區獲頒綠建築標章建築為取樣原則，調查樣本為學校類建築，共計完成24件綠建築標章建築之建造成本調查，並建立綠建築標章建築成本資料庫；另進行綠建築評估指標項目內之技術手法分析，以了解學校類綠建築提高之營建成本比例。在完成綠建築標章建築物之成本調查報告後，研提綠建築宣導與推廣建議。本研究綜合24件的學校類建築案例分析與探究，獲得學校類綠建築標章建築物之平均單位造價（元／m^2）相較於臺灣省建築師公會的標準高了3.9%。

In order to understand the differences in constructional costs between the buildings with green building label and the general buildings, sampled the buildings with green building label in north, middle and south geographic area. The investigative samples would be the buildings in the school category. There were 24 cases completed in constructional costs investigation of buildings with green building label, and constructional costs database of the green building label was established. In addition, for the sake of understanding the raised proportion of constructional costs in the school category, the technique analysis was preceded in green building evaluation index items. The suggestions and recommendations of guiding and popularizing green building would be proposed after completing the constructional costs investigation of buildings with the green building label. After integrating 24 cases of building case study and analysis in the school category, the average unit constructional costs of buildings ($/m^2) are 3.9% higher compared to the architects union in Taiwan.
