Ensuring that a common language of "energy efficiency" is spoken by both BIM software and energy analysis and simulation software is the goal of new research funded by ASHRAE , according to Building Design and Construction .

The project will develop open-source reference models for developers to test their interoperability solutions between BIM and energy simulation software. The project will focus on the most common thermal features in buildings assumed to have the greatest impact on energy use. It will provide guidelines for describing thermal models extracted from BIM and rules for extracting those models used in whole-building energy analysis applications.

"This research will promote the inclusion of energy efficiency measures in the early design of building model development," said Mark Clayton, Ph.D., principal investigator for the project. "It is expected to greatly increase the efficiency and accuracy of energy analysis and allow building designs to achieve higher levels of energy efficiency."

According to the article , studies have shown that problems related to exchanging information among various building design software systems cause more than $16 billion/year of unnecessary expense.
