I’m trying to validate Honeybee/Energypuls through a simple outdoor experiment, using IR thermometer readings of the building’s surface temperature on a specific day and hour. However, I keep getting the same temperature/color result in the simulation, even when I change the hour for that day.
If my approach is flawed or unreasonable, I’d greatly appreciate any guidance or feedback.
HB simulation Output- Surface temperature as Ture connected to HB simulation parameter>HB model to OSM>run IDF> HB read Face Results
@TrevorFedyna Hello, I’m using LB Analysis Period component with a specific date and hour for the simulation, 24th May at 15:00 (3 PM).
The timestep input is currently empty, which means the defaults to 1
period output is connected to period_ of hb color faces
What concerns me is the significant discrepancy between my real-world IR readings and the output I’m getting from this tool the difference ranges from +5 to +15°C. Even after adjusting the material properties further, I’m still encountering this issue. From your perspective, is this expected? Is this ok?
@Harxth I think this from chatgpt may explain better than I can.
But, tuning an energy model to align with real world measured data can be extremely difficult.
I think that the EPW file, not that it is incorrect but they aren’t new
it looks like the epw in question is from 2009, unfortunately the climate has changed alot since then, so that may be part of the discrepancy.

It looks like the EPW file I got might even be from 2006, not 2009. Are all EPW files this old? And does this affect every simulation output, or just the surface temperature one I’m running?
