I often focus on the design aspects of the Passivhaus Standard on this blog. I’m an architect after all. However, while getting the design right is important for passivhaus, getting the construction right is equally important. The Passivhaus Standard isn’t an aspirational standard that sets good intentions but doesn’t follow through. The Passivhaus Standard has the integrity to deliver what it promises.

What does this mean for a builder who is asked to construct a building to the Passivhaus Standard? I explore this question with Darren Macri of Bleu Nest. He shares his journey to becoming a Passive House Builder. He also shares some of the mindset shifts and new ways of working that are needed to build to the Passivhaus Standard. And you get a taste of his infectious humour.

What does it take to be a Passive House Builder?

This blog post is a review of “Passive Houses: Energy Efficient Homes” published in March 2012. Chris van Uffelen, who compiled this monograph, is a prolific author with over 50 architecture and design related titles to his name. The book surveys 56 single-family energy efficient homes from around the world that collectively

showcase the great variety of exciting and at the same time sustainable architectural solutions.

I first heard of this book when Murray Durbin mentioned it during his interview on the Home Style Green podcast. Murray and Lee Ann Durbin had found this book to be a particular inspiration when setting out to design their own residential Passive House in Auckland, New Zealand. They have written extensively about the process and you can see pictures of the completed residential Passive House on their blog.

It is a well-deserved recommendation. This book covers an enormous geographic and climatic range, and it showcases a wide variety of architectural styles and approaches to energy efficient homes.

“Passive Houses: Energy Efficient Homes” includes houses from the USA, Canada, England, Wales, Germany (as you would expect!), Austria, Switzerland, several Scandinavian countries, Australia, China, Japan and more. The author didn’t limit the choice to only certified residential Passive Houses, but instead selected inspirational energy efficient homes demonstrating a whole range of standards, all employing ‘passive’ techniques of one sort or another.

Out of the 56 homes showcased, at least 18 are certified to the European Passive House Standard and 6 to the Swiss Minergie Standard, which is very similar. Many examples meet a different standard such as the Califorina Green Building Standards Code, KfW40 (a German low energy standard), Energy Star and the UK’s Code for Sustainable Homes Code 6. There are also some certified to multiple complimentary standards. For example the Prescott Passive House in Kansas City, USA, is Passive House certified and also LEED Platinum.

This blog post is a review of An Introduction to Passive House by Justin Bere published in December 2013. Justin Bere, a pioneering passivhaus architect in the UK, wrote and compiled this slim and beautifully presented volume.

This is first and foremost a book addressed to the architectural industry, as Dr. Wolfgang Feist writes in the foreword:

Justin Bere uses the language of an architect … and shows how Passive House opens up new possibilities for creative design.

The two key themes for the book are set in the Preface:

  • Integrated Design for the 21st century, that is to say, for the anthropocene, and
  • Building Physics – using the right tools & process to eliminate guesswork

The following sections of the book pack in a wealth of interesting and useful context, history, introductory technical guidance and wide-ranging inspirational case studies.

Throughout the book there are reminders, directly and indirectly, that architecture must also be beautiful to be successful.
