Passivhaus is known as the world’s leading energy efficiency standard for buildings. It drives building energy consumption down as much as 90% compared to code requirements.

Passivhaus requires that the whole delivery team pay very close attention to how a building is designed, detailed and constructed. Energy must be used efficiently and not wasted. Very detailed energy and performance modeling must be carried out using the PHPP during the design process.

This can seem complicated and technical, on top of all the other challenges of being an Architect. So why not leave it to the ‘sustainability experts’ who love this kind of thing?

It is true, Passivhaus does take effort. It’s simple but not easy. However, Passivhaus offers important opportunities for architects.

Here are three reasons you should get into Passivhaus: Climate Change, legislation, and to make a difference.

This blog post is a review of “Hermann Kaufmann IZM: Illwerke Zentrum Montafon” published in April 2015, edited by Marko Sauer.

This is a beautiful book about a beautiful building. The IZM is a new 120m long, five-storey office building in the Montafon valley of the Vorarlberg region in Austria. It brings together, in a central location, both the civil and electrical engineers of the hydropower generation company, Illwerke Vorarlberg.

The Illwerke Zentrum Montafon (IZM) in Rodund is an unparalleled timber structure: with a usable floor area of over 10,000 m2, it was the largest office building made of wood in Central Europe on completion. Assembled in only six weeks, the timber construction above the concrete base is the first application of the LifeCycle Tower (LCT) system on the free market.

The building is an exemplar of integrated architecture. The alpine setting, materials research, modern technology, prefabrication, traditional craftsmanship, low energy / low carbon design, and social contribution all play their part in making the IZM a work of stunning Passivhaus architecture.

“Hermann Kaufmann IZM: Illwerke Zentrum Montafon” is an elegantly restrained monograph of essays, beautiful photographs and clear drawings. It is, in a sense, reflective of the building itself. It maintains the very high standard of presentation and technical detail that can be found in all Detail magazines and books.

Passivhaus architecture is integrated architecture. This book details an exceptionally beautiful work of integrated architecture.

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.”

Architecture is often described as the combination of art and science. The role of art in architecture is understandably subjective and open to debate. However, what about the role of science in architecture?

Clearly buildings do obey the laws of science, as they must. And specifically, the structure and services of a building are calculated and designed using physics. Understandably, it is most often these areas of science that get expressed in architecture. We can see this, for example, in the structural expressionism of Santiago Calatrava or in the romanticised high-tech style of Richard Rogers.

Aside from structure and building services, however, does science inform architecture in any other ways? Perhaps not as often as it should! As I wrote about previously, design is central to passivhaus. And science is central to passivhaus design – at the macro level of form and orientation, and at the micro level of airtightness and thermal bridging.

Science is a reason to Love Passivhaus!

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.
