Project Objective

Approximately 41% of U.S. households are in the Northeast and Midwest regions, where deep foundations are the dominant below-grade construction style. This project at Oak Ridge National Laboratory (ORNL) aims to identify energy-efficient, durable foundation insulation systems—customized to climate zone, soil type, and insulation system—that do not accumulate moisture. WUFI has been deployed and validated for decades worldwide as a tool to predict heat and moisture transfer in building envelopes, and it has been successfully adopted for use in the United States by ORNL. The fiscal year 2014 goal of the project is to assess the viability of WUFI 2D as a tool that can be employed for below-grade construction, and to initiate fixes as required, in collaboration with Fraunhofer Institute of Building Physics.
