I?m looking at transitioning from Energy-10 to EnergyPlus. I often need
the
ability to model a building in more detail, and more thermal mass
accuracy.
However, E+ is Slooooow. Obviously E+ is much more sophisticated and
E-10
only models a rectangular shoebox. But when E-10 can simulate a
simple
building in 30 seconds for the whole year, while E+ takes 50 minutes,
it
becomes painful to iterate the design a dozen times.
Three questions:
1. Does E+ have a
?shoebox mode? where is lumps every thing into a
simplified building? I know it has an option to lump windows, but from
what
I?ve seen this is not enough.
2. I noticed that Running
without HVAC was MUCH faster. What are best
settings to speed up the HVAC code?
3. If I get a new 4
processor computer, is E+ written to efficiency
take advantage of multiple processors? Are there any benchmarks?
