Integrated design is a key element of successful passivhaus design, as I wrote about in a previous post. Certified passivhaus designers and consultants are often architects, building services engineers or sustainability specialists. So how important to the integrated design process is the structural engineer? The answer is: vitally important!

There are significant benefits in having a structural engineer who is also a certified passivhaus designer on the team as this post explores. Where this isn’t possible, at the very least the structural engineer needs a good understanding of passivhaus and the importance of their role in the design process.

Structural engineering has a significant impact on design simplicity, thermal continuity, airtightness and more.

The mainstream approach to sustainable design is business-as-usual architecture with some easy bolt-on “sustainable features.” Easy solutions like this are what got us into the current mess: buildings contributing 40% of our CO2 emissions as we enter the anthropocene. (Have you read my manifesto?) Designing to the passivhaus standard means accepting more constraints and this requires more effort; it’s not an easy solution. A rigorous process must be followed. However, the passivhaus standard is actually very simple with clear performance benchmarks that must be met. And the results are simple: no complex offsetting or complex carbon calculating is necessary.

Passivhaus buildings simply reduce energy consumption and CO2 emissions, by design.
