Hi to everyone,
I am using Daysim/Radiance to calculate the lighting loads and then I import the associated schedule file to Energy Plus. Now just say that I have two window parameters ( single @ double glazing) and the associated lighting control files lighting_control_single_glazing and lighting_control_double_glazing. How can I combine single glazing with lighting_control_single_glazing  in order to avoid combinations like single_glazing  with lighting_control_double_glazing?
Thanks in advance,
Kostas

Hi Kostas,

Using EP-Macro will be essential here. If you haven't tried it, there is video tutorial here: http://www.jeplus.org/wiki/doku.php?id=d...:3_epmacro for a quick introduction. The full details of EP-Macro is in the official document (http://apps1.eere.energy.gov/buildings/e...ograms.pdf), from page 129.

You can save the lighting schedules in text files separately, and import them into the main IDF (now should be named IMF) model using the ##include command. If you name the schedule files carefully, so they are aligned with the glazing options, you can then control both with one parameter.

For example, if the glazing parameter uses search tag @@glazing@@ with two values {single, double}, you can name the schedule files as lighting_single.idf and lighting_double.idf, respectively. And then in the main model, import the schedule file with ##include lighting_@@glazing@@.idf...

There are other ways to do this, such as using the combinatorial parameters (see: http://www.jeplus.org/wiki/doku.php?id=d...parameters)

Hope these make sense...

Yes, they make sense. Many thanks for your reply.
