Hi!

I am trying to simulate a PassivHaus in energyplus via OpenStudio and I am finding several problems with that. I tried with the following layout, but it doesn't do anything. I want to keep the inside temperature about 18-20ºC always, working with a heat exchanger using the exhaust air to take the heat in order to reheat the outdoor air when it comes in (sorry for my bad english)

I attached a few images about I want to do. Thank you very much. I am so stressed with this.

Edit -----

Okay, now, I've included the ERV in my ThermalZone, and edited it. I found some problems here...

1. The first one. I don't know how to draw the airloop to add the ERV. I tried to add it in the one I posted (Link “My layout”) but I got a failed simulation. I am so lost here.
2. When I am editing the control of my HVAC, I selected "Siempre 20º" (Always 20ºC), but in the results I don't get that. The temperature comes from 10 to almost 30ºC.
3. When I am trying to edit the ERV, the Air Inlet Node Name and Outlet have a very strange name, so I can't identify the correct ones. In addition, I don't have the proper air-loop to know that nodes.
4. Another question that I have is about the schedule that I need for Heating Thermostat and Cooling Thermostat. Should I use time? temperature? always on?
5. I don't know either what type of SetPointManager use to set the temperature always in range between 18-24ºC

I am working with OpenStudio since November for my Final Project, and this is a completely chaos.

I put some links to helpful screenshots of what I want to explain.

Edit 2 ------

I've deleted the air-loop, inserted a Recovery Ventilator in the Zone Equipment. But now, when I try to simulate, I get an error that didn't happened before... It says: Object=Wateruse:connections, name=Water use connection, Required Field=Water Use Equipment 1 Nambe (was blank)..

I've checked all the water system and the equipments has name. I am so confused cause I dind't change anything else and this error appeared.. Here some image references.
