There are four SurfaceConvectionAlgorithm:Inside and five SurfaceConvectionAlgorithm:Outside options for calculating surface convection in EnergyPlus. The default for inside is TARP and for outside is DOE-2 and I've never really considered trying the other options.

My question is what are the differences between the algorithms (in theory and in practice)?

• Do some run faster than others?

• Are some better-validated than others?

• Do some capture different effects?

• Are some more robust to errors/inaccuracies in input parameters?

Essentially, under what situations would it make sense to use anything other than the default options?

• How large are the differences (in energy use or indoor conditions) when using different algorithms?
