Hello everyone,

I am having logic issues with some results on energyplus cooling load simulation (15 August). The main issue is that my exterior walls are showing negative Surface Inside Face Conduction Heat Transfer Rate while Outdoor Surface Temperature (37ºC) is above Interior Surface Temperature (21ºC).

Simulation is showing Peak Load at 7:30am from one NE space, which makes sense. What does not make sense is having negative conduction when outdoor surface temp is hotter. Following you can see graph of these hourly day simulation.

Thanks in advance, Hope you make me see the light in this phenomena analysis
