Abstract LEED is widely used to guide green building design and evaluation. However, since in most cases, the construction cost is not the main evaluation content, the building energy saving is often accompanied by the cost increase, so the owner’s willingness to participate spontaneously is not high. This paper takes residential buildings as an example, and uses BIM simulation technology combined with value engineering to analyze the relationship between cost and energy saving in the architectural design process. Based on the establishment of the REVIT model, Ecotect is used to simulate the energy consumption. By comparing the energy-saving performance of different schemes, the LEED score is calculated to determine the most costeffective design. The study found that in the design stage, BIM tools combined with value engineering can better optimize the design and find a balance point that meets the requirements of green building evaluation and owner.

1 Introduction With the intensification of resource demand conflicts, building energy saving has received more and more attention. It is also the most important indicator of green building. Its goal is to improve energy consumption efficiency and reduce construction in buildings without influencing to the comfort of living. Planning and design time is an important stage of energy consumption affecting construction costs and operation period. Different design plans will have huge differences in energy consumption during operation period. Modern building design can perform complex data calculations and real-time dynamic simulations with numerical techniques and appropriate auxiliary design tools, and use its simulation results to optimize the solution to help designers complete the preliminary and detailed design of the building. Researchers and developers have grown increasingly interested in BIM application in terms of the design, planning, and construction of new buildings (Leite et al. 2011; Chong and Wang 2016; Boukamp and Akinci 2007; Gray * Taibing Wei [email protected] Yuxin Chen [email protected] 1

There have been major research trends focused on the improvement of preplanning and design, clash detection, visualization, quantification, cost analysis, and data management (Bryde et al. 2013; Rasiulis et al. 2016; Elmualim and Gilder 2014). In BIM’s research on building evaluation and energy analysis, Alwan et al. (2015) applied BIM technology for building environmental evaluation. The study found that applying BIM technology can quickly and efficiently perform LEED evaluation. Jalaei and Jrade (2015) focuses on the combination of BIM and LEED. Jrade and Jalaei (2014) proposes a method to combi
