IES-VE User Forum

In 2016 VP does not always show the correct HVAC network ASP file. For example, several times I've made major changes to a Proposed.asp file (added a new prototype system, added coils to an air stream, added a waterside loop, etc.), run room and system sizing for that ASP file and then run an annual simulation only to find that when I open the same Proposed.asp file in VP it shows an older version without any of the changes I made.

yes I have run into this problem as well, and when contacted IES support, they said they will work on it in future patches/versions. Currently the workaround is that whenever you do any change to the network in proposed or baseline, save the simulation run under a different name.

This is a PITA for debugging models. I shouldn't have to save a different APS file every time I run a sim. VE models are already bloated enough without having to save a new file every time the user makes a change.
