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.

This is a Passivhaus Basics blog post that gives an overview of the Passivhaus Standard. Want to watch a 2-minute overview first? Jump to the video at the bottom

The Passivhaus Standard is often referred to as “the world‘s leading standard in energy efficient design.” And usually a description of the standard includes details of the specific technical requirements. (If you are curious about the technical requirements, I cover the key elements in this post.)

The Passivhaus Standard is indeed an international, rigorous, scientific, performance standard for the design and construction of energy efficient buildings. It applies to all kinds of buildings, not just houses. However, the Passivhaus Standard is not just about the technical requirements of energy efficient design, it encompasses:

  • Comfort
  • Energy Efficiency, and
  • Quality Assurance

It is the combination of these three key aspects that make the Passivhaus Standard what it is.

What do Comfort, Energy Efficiency and Quality Assurance mean in practical terms for a house that is certified to the Passivhaus Standard?

Bjarke Ingels is a “Starchitect,” an international superstar architect. He is also a great storyteller and perhaps this is why he has risen to such prominence in recent years. People love stories.

Arguably, it is the narrative that people give to buildings that elevate them to “Architecture.” The trouble I have with most “Starchitecture” is that the narrative often appears to be whimsical, egocentric and divorced from environmental context.

Bjarke Ingels is a different kind of “Starchitect.” He offers a narrative where architecture embraces environmental context. His term for this is “Vernacular 2.0.”

Vernacular architecture arises out of a direct response to the climate it inhabits and the resources available locally. And this is exactly what the Passivhaus Standard aims to ensure in a contemporary context.

So what would happen if the two were combined? Can you imagine an architecture where the “Hedonistic Sustainability” of the Bjarke Ingels Group (BIG) delivered the radical energy efficiency and exceptional comfort of the Passivhaus Standard?*

I can.

The combination of Bjarke Ingels + Passivhaus, to my mind, truly would be a “Vernacular 2.0.”

Our baby was born early in April, just as Spring is arriving here in the northern hemisphere.

Our house isn’t a passivhaus home.

There are many reason’s why we don’t yet live in a passivhaus home, but that isn’t the subject of this blog post. Now with a new baby as well as our toddler, even more so than before, I wish we did live in a passivhaus home. I care very deeply about the comfort and health of our children. And knowing first-hand the benefits of the Passivhaus Standard, I am acutely aware of what we are missing out on.

Affordable to run, comfortable and healthy to live in, passivhaus homes are ideally suited to young families. Of course, passivhaus homes are ideally suited for all people to live in! However, young children are particularly vulnerable and in need of comfortable and healthy homes. And with the cost of bring up children, parents need a comfortable and healthy home to be affordable.

Sustainable and environmental design are often talked about in terms of the benefit for future generations. Unfortunately, despite the good intentions, this can be abstract and vague. The Passivhaus Standard, on the other hand, is a practical immediate solution that benefits the next generation, today.

The Passivhaus Standard ensures homes are comfortable, healthy and affordable to run. Passivhaus homes are of immediate benefit to next generation: our children.

This blog post is a review of “Passive House Design – Planning and design of energy-efficient buildings” published in September 2014. Author and architect Roberto Gonzalo (who also wrote the 2012 title “Energy-Efficient Architecture”) and passivhaus architect Rainer Vallentin collaborated on this valuable guide for architects and designers.

This is a timely book as the delivery of passivhaus architecture accelerates around the world. As the authors note, more and more architects are finding their way to passivhaus:

…simply because it is one of the most scientifically sophisticated and practical energy efficiency standards for buildings currently available.

Thorough introductory and background material is provided for those that are new to the Passivhaus Standard. This is followed by chapters dealing with a range of subjects in suitable detail for those already familiar with the standard. Well-illustrated case studies complement both the introductory and the more advanced content.

“Passive House Design” is an extremely useful book full of beautiful photographs, clear diagrams and detailed drawings. It maintains the very high standard of presentation and technical detail that can be found in all Detail magazines and books.

Passivhaus architecture depends on the design and construction quality of the building envelope. This book guides you in designing the building envelope.
