People are always very appreciative and often go away saying they've learned a lot. They genuinely appreciate being able to experience being in a passivhaus. I think they are genuinely surprised by how warm and comfortable they are to be in.

Curious and engaged crowds

One of the highlights of participating with a project for the event is the interaction with curious and engaged crowds. This year seemed to attract many self builders and architects, along with construction professionals and intrigued locals. Will this translate to a rise in self build Passivhaus schemes?2015 UK Passivhaus Open Days The Fish Factory

Some common questions that arose from the event:

  • What are the pros and cons of going for Passivhaus certification?
  • Will Passivhaus add value to the property?
  • What is the build cost, and is it more than a 'conventional' build?
  • Where do you find contractors to build to this standard?
  • How much are your annual heating bills?

We enjoyed the genuine interest by all visitors, with always very clever, interesting questions. It seems the word is slowly spreading and people think more and more about Passivhaus.
