May you don’t know us yet, let’s have a quick introduction: we are ERA architects.
Actually, I am Esther Rovira, architect and passive house designer in Barcelona, Catalonia and Andorra for either passive houses, efficient houses and positive houses.
In this post ‘6 musts for a positive house’, You will find our professional recommendation.
I hope it helps you!


Here the 6 musts for a positive house (click on each item to get all the info!):

  1. Compact volume
  2. Insulation
  3. NO thermal bridges
  4. Airtightness + ventilation
  5. Special windows
  6. Renewable energy 


Our professional recommendation:
Ask your architect to prove how these item list is solved on your positive house design before you even start construction.
We’ve had so many clients coming from other architects with projects ‘supposed to be sustainable’ when it was too late.
They usually already have the permits and ready to start building, but of course they have to re-do the design to make it sustainable for real and then loosing 1 or 2 months on the way.
