ESP-r to Blender
I stumbled upon this on YouTube, actually the AI probably put it in front of me
Wikipedia says...
ESP-r is a research-oriented open-source building performance simulation software.[1] [2] ESP-r can model heat flow in thermal zones, fluid flow using networks or CFD, electrical power flow, moisture flow, contaminant flow, hygrothermal and fluid flow in HVAC systems, as well as visual and acoustic performance aspects within a modeled energy system/building.
