I'm doing a infiltration effective leakge area in openstudio, but when the program appears an error this say ''<root>[ZoneInfiltration:EffectiveLeakageArea][Space Infiltration Effective Leakage Area 1] - Missing required property 'zone_name'.'' and i don't see any space that that lets me write the name of the zone....please help me

is your space part of a zone? The calculations are done at the zone air calculation level, so if your space isn't part of a zone, it won't have a zone_name to reference.

and how can i assing a zone to my space ?? when you say ''zona'' is the same that ''thermal zone ?

yes, zone = thermal zone. There is a thermal zones tab in OpenStudio where you can add thermal zones, and then in the Spaces tab you'll drop them in to the Thermal Zones column. You define thermostats in thermal zones. You can also do this in the SketchUp app - see the tutorial

I have already assigned the thermal zone to each space and still the error persists, I do not get the box to write '' zone name ''... i don't know what more i can do

I recommend using the space infiltration design flow rate object instead of the space infiltration effective leakage area.

If you want to use the space infiltration effective leakage area object, you need to specify it in the spaces tab, not the space types tab:

Some other notes:

  • The schedule for your space infiltration effective leakage area object should be an OnOff operational schedule, not an activity level.
  • Add heating and cooling thermostats to your thermal zones
  • You probably want to include other loads besides just interior lighting

I have other quetion, if i want to work with passive meassures, i have to add heating and cooling thermostats to my thermal zones?

If you have any system assigned to your zone you will need thermostats. You can always set them to high/low values, e.g. a 110F cooling thermostat and 40F heating thermostat so that the system never turns on for conditioning.

I've run into the same issue, helpful to see I can solve this by assigning ELA at the space level. Would be great to make it so that users cannot apply ELA to the space type tab given this issue. Thanks

Also, I would love it if you could delete these objects without going into the osm via text mode.
