In response to the need of using electronic design data directly in construction management applications, many CAD developers have started implementing semantic data models in their CAD products using industry foundation classes (IFCs). While helpful, these semantic CAD applications have limitations when used in actual construction practices. The case(More)
The transition to Building Information Modeling (BIM) represents a substantial shift from existing business practices in the architecture, engineering, construction, and facility operations (AECO) arena. While the move from drafting to computer aided design (CAD) sought to automate an existing business practice, successful BIM virtually builds a structure(More)
Commercial buildings consume nearly 20% of all energy used in the United States, costing more than $200 billion each year. The building envelope plays a key role in determining how much energy is required for the operation of a building. Individual thermal and solar properties of glazing and shading systems only provide information based on static(More)
The vision of semantic interoperability, the fluid sharing of digitalized knowledge, has led much research on ontol-ogy/schema mapping/aligning. Although this line of research is fundamental and has brought valuable contributions to this endeavor, it does not represent a solution to the challenge, semantic heterogeneity, since the performance of proposed(More)
