Revision history [back]

I am looking to show the impact of thermal mass on building performance and looking for an hourly report that shows the time delay and peak load shaving that is typical of a thermally massive wall. EnergyPlus outputs include conduction, convection, radiation, and storage variables, but I am struggling to interpret the results and their relation to the zone.

Intuitively, I figured the convection and radiation components of the inside surface would add up to the heat transfer to the space, but the results don't match the trends I was expecting. This sum shows the shift in peak load, but a mass wall of similar U-value has much higher peaks than a frame wall.

The table outputs show a peak load for each zone, but I am looking for hourly trends and would like to evaluate walls by exposure. I am not looking for the total zone wall heat transfer.

Can someone shed some light on this for me?

Thanks, Tim
