[EnergyPlus_Support] Re: Plant and System changes during macro runs
Mike,
Thanks for your response. I have been using the ##if blocks to
institute smaller changes - like changing material conductivities -
and I understand the potential for using the compact HVAC objects,
but I am interested in installing customized HVAC systems. I
understand that using the ##if blocks is one way of doing this, but
this may require replacing large blocks of code to make major system
changes (like going from an electric baseboard heating sytem to a
water-based baseboard heating system). Have you observed any issues
with doing this? Are Compact HVAC system the only other way
of "simply" switching between HVAC systems when running a macro? I
hope this explains what I am interested in a little bit better. I
would just like to make sure that I do not make this more difficult
than I need to!
Thank you for your help!
