Hello all,

I am working on a study project, and looking for ways to model glazing switch in eQUEST explicitly, meaning, forcing eQUEST to do one of the following:

Option 1: Switch GLASS-TYPE (4 available) based on the hour of the year, and not use eQUEST's built-in glazing switch functionality.

Option 2: Use the Layer-By-Layer specification method, and switch one layer based on the hour of the year.

I imagine that Option 1 is achievable with a user expression input for GLASS-TYPE, something along the lines of:

Hour 1: "Glass A", Hour 2: "Glass B" ... Hour 8760: "Glass D"

For Option 2, we would also need a similar user expression input for the window layer being switched (such as Hour 1: Layer 1...Hour 8760: Layer 4).

Part of what I am trying to look at is the simulation runtimes in these options, besides the effect on annual results.

I'd really appreciate if someone could help with writing user expressions for these 2 options. Once I have the format/s for them, I can automate it quickly in Excel and then back into eQUEST.

Thank you.
