3 Key Insights from the PassivHaus Playbook

During my summer break, I finally caught up on some reading and delved into the PassivHaus Playbook, released in November 2023. Here are three fascinating takeaways:

  • The capital costs for this PassivHaus pilot project are approximately 2.8% higher than the baseline.
  • Professional fees account for nearly a third of these cost increases (This is a bit higher compared to other certification schemes, like Green Star).

Breakdown of capital costs uplift

  • The most significant cost item? The Heat Recovery Ventilation system, an essential element to PassivHaus design, adding nearly $10k per apartment.

Breakdown of construction costs uplift

My perspective? A cost uplift below 3% seems like a best-case scenario for PassivHaus Certification, mainly applicable to large-scale projects due to economies of scale. Smaller projects might see a higher percentage increase.

Have you seen similar trends in your PassivHaus projects? I'd love to hear your thoughts on this!

Kudos to Development Victoria , Australian Passivhaus Association , and Introba Australia for this insightful resource!

Professional fees need to be much higher so consultants don't lose money on projects.... and I would question that 2.8% if we are to be honest. If you want a Ferrari, expect to pay for it. Great resource, though.

Thank you for sharing however th cost of damage due to condensation and mould is still not well documented which can clearly ascise why added cost to MVHR is required. I love to see more training on installation sometimes incorrect installation could even be more of an issue. Hence these conversation like this is so important.

Great post! What jumps out for me is the biggest increase to capital cost is from the MVHR - this is a piece of equipment that improves indoor environment quality, reduces risk of condensation and risk of mould in addition to providing heat recovery & reducing heating demand. Why wouldn't you want one anyway?! .. not to mention these are almost ubiquitous in new apartments in London!
