BIM-Based Approach to Simulate Building Adaptive Performance and Life Cycle Costs for an Open Building Design

In the long-term use of buildings, renovations are sometimes required as usage behaviors have changed and residents’ demands for space are adjusted. However, the public in general are deficient in renovation knowledge and information regarding building use and its maintenance phases; thus, the initial stage of planning and design often lacks flexibility, leading to waste materials in the subsequent renovation project. Theoretically, Building Information Modeling (BIM) can be used as a building unit resume and renovation benefit prediction tool; moreover, it plays an important role in the usage and maintenance phases. This study develops three design proposals that target different service lives (30 years, 50 years, 100 years), as based on the building’s expected life, and uses BIM technology to simulate the life cycle cost and design performance, as based on the renovation scenario analysis of the building’s life cycle. The findings show that under the service condition target of 100 years, when the open flexible technique is used for the design, space utilization flexibility is enhanced, pipeline maintenance is convenient, waste is reduced, and performance in life cycle cost is better. BIM can predict performance simply and rapidly according to future usage demand adjustments after the initial design
