I've been trying out floorspacejs in the OS 2.6 and it is not clear how to specify a pitched roof for a building. Is this an implemented feature? There's a drop-down menu under "pitched roof" in the expanded navigator window but no options in it.

Thanks in advance.

Thanks for the quick response. It's unfortunate this feature is not available yet, I think floorspacejs could otherwise

Thanks for the response Julien. I'll have to try your recommended approach.

Indirectly heated water heater with a backup electric heater - IndirectHeatAlternateSetpoint I've been trying to figure

I am relatively new to EnergyPlus and I am currently studying the documentation as well as all the guides/examples included with the software. At the moment, I am trying to better understand how part load performance is modeled in EnergyPlus for something like a residential gas furnace. I am hoping someone can provide a little clarification on some of the requirements for defining a part load factor (PLF) performance curve for a fuel-fired air heating coil.

According to the engineering manual, the PLF curve, which is a function of the part load ratio (PLR) has to following the following rules:

- PLF > = 0.7

- PLF > = PLR

While I think I understand the second requirement, the first seems somewhat arbitrary to me and I have not been able to find justification for why PLF must be greater than 0.7. This requirement of the PLF curve appears for other HVAC equipment as well.

If anyone is able to provide clarification on this requirement it would be greatly appreciated.
