Denver Chapter - Kiva: Fast and Accurate Heat Transfer Calculations for Ground-Contact Surfaces
Description: This is a recording of a Denver Chapter webinar, held on 5/18/17.
Calculation of heat transfer from building foundations is a computationally intensive three-dimensional problem that can require several weeks to solve using current computing hardware. Historically, annual building simulation tools use greatly simplified assumptions at the expense of accuracy. Kiva performs fast, multi-dimensional heat transfer calculations in a matter of seconds with highly accurate results. This presentation describes the methodology used to develop Kiva, and provide an overview of the recent implementation of Kiva in EnergyPlus.
Presenter: Neal Kruis is Vice President of Big Ladder Software. He is a developer for both EnergyPlus and the California Simulation Engine. Neal holds a doctoral degree in architectural engineering from the University of Colorado at Boulder. His primary interest is developing high performance computing software for numerical analysis of buildings. This has lead to the creation of Kiva, a numerical framework for improving the calculation of heat transfer from building foundations. In addition to building foundations, Neal has also published research on simulating fenestration, direct expansion vapor compression systems, and water heating systems. Neal is an active member in the ASHRAE and serves on several committees developing research and industry standards. As of 2017, Neal serves on the Board of Directors for the U.S. chapter of the International Building Performance Simulation Association (IBPSA-USA).
