Thermal and Hygrothermal Simulation

We have the capability to analyze non-standard wall and roof assemblies for thermal and hygrothermal performance (heat, air, and moisture control) utilizing state-of-the-art software (WUFI Pro 5.0).

Thermal modeling software is used to analyze one, two, and three dimensional heat transfer under both steady state and transient conditions. Thermal modeling is essential for establishing overall thermal performance values and condensation potential. These tools are used to evaluate the performance of proposed roof, wall, and glazed assembly designs; forensic analysis, and support of energy credits for LEED projects. 

The majority of RDH technical staff have formal training in building science, including several staff that hold master’s degrees with specializations in building science. This training is imperative to conducting heat transfer analysis of the building enclosure.

RDH staff members have distinct training and capabilities utilizing state-of-the-art hygrothermal modeling software. This type of modeling helps in the understanding of coupled heat and moisture transfer across the building enclosure. These tools are used to:
  • Evaluate the performance of proposed roof, wall, and floor assembly designs.
  • Understand how different assembly designs perform under different interior and exterior climate conditions.
  • Perform forensic analysis to understand the cause of failures.

The majority of RDH technical staff have formal training in building science, including several staff that hold master’s degrees with specializations in building science. This training is imperative to understanding coupled heat and moisture transfer and in successfully utilizing and interpreting the results output from analysis software.

Regarding Rob Bombino, RDH Principal located in the Seattle office:

“Thank you for your time, energy and inspiration you gave on our behalf to present and lead the Net Zero Energy Workshop in Tacoma. Your name recognition and reputation as a leader in your field was a large reason for its success.  Your lecture left the audience excited to learn more.  Your presentation was expertly delivered.”
