Passive House School

29/04/2026

Last week, Svetlin and I attended the 28th International Passive House Conference in Essen - a special edition marking 30 years of the Passive House Institute and 35 years since the first Passivhaus was built by Wolfgang Feist. 🏅

✍ A few takeaways I’m bringing back:
- Inspiring to see the HUGE scale Passive House has reached globally - from "The House at Cornell Tech" and "Winthrop Center" to large-scale residential developments in Ireland.
- New milestones: Sendero Verde in the US now holds the record as the tallest Passive House building - 709 units.
- The University of Oxford is raising the bar with the largest Passivhaus scheme in England (25,000+ m²) and the first certified Passive House concert hall - the Stephen A. Schwarzman Centre for the Humanities.
- A good reminder: highly insulated buildings without proper ventilation (MVHR) can lead to lower occupant satisfaction than less insulated ones. If you do it — do it right.
- With Europe moving toward Zero Emission Buildings (ZEB), Passive House is proving to be a strong fit thanks to its extremely low operational energy demand.

👉 Great conversations, fresh perspectives, and plenty to think about moving forward.

We’ve completed the Passive House certification of a 189 m² single-family house in Cork, Ireland. 🇮🇪

The house is built with a timber structure, using cellulose insulation, an internal OSB layer, and wood fiber boards externally. A natural material palette but one that demands precision, especially when it comes to airtightness and moisture control.

What makes this project particularly interesting is how it’s heated:
👉 There is no traditional heating system.
Instead, the house is heated through the supply air of the MVHR system, via a compact unit.

Performance highlights:
• Heating demand: right at the Passive House limit (15 kWh/m²a)
• Airtightness: 0.5 ACH
• Overheating: only 1% of the year
• PER: just 42 kWh/m²a

📌 Projects like this are a good reminder:
Passive House is not about adding more systems .... it’s about reducing the need for them altogether.

🔍 Let’s get practical: How much do thermal bridges really impact wall performance?

We compared 3 wall types with 20 cm of insulation:
1️⃣ Steel studs: Though only 2 mm thick, they cause a massive thermal bridge with a λ = 0.21, raising the wall’s U-value to 0.50 W/(m²K).
2️⃣ Timber studs (6x20 cm): They also cause a thermal bridge, but much smaller — λ = 0.04, with a U-value of 0.24 W/(m²K).
3️⃣ Undisturbed wall assembly: No thermal bridges, with a U-value of 0.18 W/(m²K).

➡️ The result?
- Steel studs increase the wall’s U-value by 178%
- Timber studs increase it by 33%
This shows just how crucial it is to account for thermal bridges in design. Even small details can have a huge impact on energy efficiency and comfort!

Let`s talk about Thermal Bridges. 💬

Here are some facts:
✅ They can be responsible for up to 30% of the building’s heat loss! Of course this means higher energy bills and increased emissions.
✅ They lead to moisture issues -> mold growth -> Sick Building Syndrome!
✅ They weaken structural elements, accelerating material degradation and leading to costly repairs.

Fellow architects and builders—these hidden inefficiencies could be undermining your projects!!

👉 Our latest article dives into the impact of thermal bridges, why they matter, and how to eliminate them effectively. Check it out here: https://passivehouseschool.com/resources/blog/science-of-thermal-bridges/

👇 What challenges have you encountered with thermal bridges? Share your experiences in the comments!

Thermal bridges are the area in a building's envelope where heat flow is different compared to the heat flow through the surrounding elements.

“Will I be able to design Passive House Buildings after I finish the course?”
is a question Anton get in almost every Introductory Call.

A few years ago, we realized that most people book these calls for a few key reasons:

• To ask questions about the course.

• To clarify what to expect.

• To make sure it’s legitimate (fair enough!).

• And sometimes, just to see if we connect on a personal level.

So since then, he had the privilege of hopping on countless calls with passionate, curious professionals from all over the world. Some of these conversations have led to lasting connections - business partnerships and friendships.

In the latest video, we’ve gathered the most common questions asked during these calls. Next: thinking about making a video that dives deeper into some of the more in-depth questions I get about PH buildings— there are plenty of those too!

If you’re considering the Passive House course, this video is a great place to start. But honestly, we’d still encourage you to schedule a call. It`s a true enjoy these conversations, and we’d love the chance to hear your story.
