I have used EMS scripts in DesignBuilder (DB) previously and relied mainly on four sources:
- Design Builder
help
and now there is this helpful DB
EMS demo
tutorial.
- A webinar recording on Advanced
EnergyPlus Modelling with
DesignBuilder EMS.
- There are some EMS program examples in DesignBuilder that would be good way to start
specially if they are
close to what you are trying to model.
- Since DesignBuilder uses Energyplus
you may want to refer to the
Application Guide for
EMS as well.
These sources should be helpful to get you started.
