Since the sustainable issue has become a trend in recent years, the adoption of building performance analysis (BPA) tools in design process is not a news today. However, according to the literature review revealing the “rule of thumb” was still the measure when architects discuss the green building design. Also, the lack of background knowledge could always be noticed between the intention of sustainability and design works in either academic education or design practice. Therefore, this study was started on the BPA software training course of basic knowledge and application through the early design phase. To close the gap, a guided workflow of BPA tools was proposed for the designer’s needs. The guided workflow was used to draft a pilot experiment course in architectural education with 7 trainees. In order to enhance students’ fundamental knowledge. The results of the experiment showed subjects have a significant improvement on the knowledge of BPA tools (p-value <0.05), nevertheless, energy simulation learning showed on the opposite. The results also indicated that the individual discrepancy might cause the effect on factor of “Perceived Ease of Use”. In conclusion, based on the results of experiment above, the grading course with learning objectives, training methods and contents have been modified and suggested.
