While contemporary architects desire the integration of passive solar heating strategies into design concepts, energy performance is still difficult to predict due to the complexity of related physics. Few energy modeling tools provide passive solar heating because the selection of CFD turbulence models for buoyancy low velocity phenomena and solar radiation models remain a challenge. Utilizing the Interlock House, a 2009 US DOE Solar Decathlon home and Iowa NSF EPSCoR community lab our team conducted refined measurements of passive solar heating effects on a sunny day (March 8th, 2015) in order to validate new approaches to CFD model selection.
