Guo, S.-J.S.-J.GuoWei, T.T.WeiSY-JYE GUO2019-12-202019-12-202016https://scholars.lib.ntu.edu.tw/handle/123456789/437833This study utilized BIM technology (eQUEST) to conduct an energy consumption analysis and simulated re-design of the Civil Engineering Research Building at National Taiwan University. After obtaining a verifiably accurate simulation, energy-saving effects were investigated by altering the building's envelop design and analyzing the results. In addition, cost remains a crucial factor throughout the process in order to reflect the relationship between building expenses and energy efficiency during design scheme optimization. The results of this study can provide better and more comprehensive choices for building owners, designers, and developers in future. © 2016 Elsevier B.V.Economic analysis; Energy consumption; Energy simulation; Envelop; Orthogonal design[SDGs]SDG7Cost effectiveness; Design; Economic analysis; Energy conservation; Energy efficiency; Energy utilization; Engineering education; BIM technologies; Building owners; Energy consumption analysis; Energy simulation; Energy-saving effect; Envelop; National Taiwan University; Orthogonal design; Architectural designjournal article10.1016/j.enbuild.2016.06.0152-s2.0-84975299318https://www.scopus.com/inward/record.uri?eid=2-s2.0-84975299318&doi=10.1016%2fj.enbuild.2016.06.015&partnerID=40&md5=76d8b4819beaa6a173dc07534f0f3b5f
