About Passivhaus HUB

We can build
better than this

Everyone deserves a healthy, comfortable home they can afford to live in.

At Passivhaus HUB, we teach designers and tradespeople how to turn that belief into better building decisions. Our work brings together experience from the building site, architecture and building science, with a shared determination to make a difference.

Our ambition

Better housing needs a step forward

Housing is asking more and more of people's lives, earnings and futures. We refuse to accept that the answer is to lower expectations of comfort, health or safety.

We need to rethink how homes are designed and delivered. Better planning, intelligent prefabrication and more efficient construction should help make quality housing accessible to more people.

“We didn't develop cars by improving horses.”

Daniel Kress

That is how we think about the change our industry needs.

For us, Passivhaus provides the building-science foundation: understanding how to create buildings that protect comfort and health while keeping energy demand low. Smarter design and delivery must help make that quality more affordable.

Our part is to give building professionals the knowledge and confidence to move this forward, project by project.

The people behind the teaching

Design. Build. Ask better questions

Different experience. Shared determination to make better buildings possible.

Founder & Head Trainer

Daniel's experience spans carpentry, prefabrication, civil and structural engineering, and sustainable-building research. He brings a practical question to everything he teaches: how does this work when someone actually has to build it?

His belief that we can always do better is the starting point for Passivhaus HUB.

Daniel's journey

A few countries. A lot of questions

From childhood shelters in Germany to construction sites in Ireland and Passivhaus research for Perth, Daniel has kept asking how buildings could work better.

Open Daniel's journeyClose Daniel's journey
  1. Illustration · curiosity, timber and trial and error

    01 · Germany

    Curiosity came first

    At six, I was already building shelters. One experiment with electric lighting nearly set one on fire. My curiosity was clearly ahead of my electrical knowledge.

    By ten, I was helping turn an old farmhouse into our family home, getting involved in demolition, mixing concrete and installing plasterboard.

  2. Illustration · from drawings to assembly

    02 · Germany & Ireland

    Learning on the tools

    Carpentry took me from Germany to construction work in Ireland, including large-scale modular building.

    A decade in construction taught me to look beyond the drawing. Someone has to put the building together, and the decisions made on site stay with it for years.

  3. Illustration · following the building science

    03 · Engineering & research

    Following the why

    I wanted to understand more of the science behind what I was building. That led to master's degrees in civil and structural engineering and work on a European sustainable-building research project.

    Practical experience and building physics started answering each other's questions.

    04 · Perth research · 2015

    A new climate. More questions

    My thesis investigated Passivhaus design for Perth, Western Australia. More than 600 PHPP variations helped me explore how design decisions affected the reference home's performance.

    It brought the science back to a practical question: what would work here, and why?

    Knowledge worth sharing

    Teaching brought those experiences together. Through Smart Plus Academy, now Passivhaus HUB, I could share what I had learnt with people who would take it into their own projects.

    Julia brought her architectural experience to the teaching team in 2020. Together, we keep refining how the ideas are explained, practised and connected.

    06 · Still asking

    How can we do this better?

    That question still drives me. Better explanations. Better building decisions. Better ways of making quality housing possible.

    Every student brings another opportunity for that knowledge to reach the next project.

Built with care

Years of work. Plenty of heart. Still improving

We have poured our experience, energy and a fair bit of ourselves into these courses.

The drawings, explanations, exercises and reference materials have been developed with care, then revisited as students show us what helps, what needs explaining differently and where people get stuck.

Our approach is constant, never-ending improvement. Clearer explanations. Better examples. Stronger connections between ideas.

We want the next person learning with us to benefit from everything the previous students have taught us.

Applied knowledge is power

A qualification matters. What you can do with the knowledge matters long after the exam.

That is why you work through drawings, calculations and decisions yourself. The recorded teaching introduces the ideas; the homework gives you the opportunity to put them to work. Later, the retrofit module brings those ideas together in a different context.

The aim is understanding you can carry into your next project, whether or not it seeks Passivhaus certification.

What we stand for

Strong opinions. Open minds. Practical action

Question the usual way

“We've always done it this way” deserves a better conversation. We look at the evidence and stay willing to change our minds.

Care about the consequences

Buildings shape people's lives for decades. Health, comfort, affordability and environmental responsibility belong in the same decision.

Help each other improve

Designers and tradespeople bring different experience. We value both, welcome questions and learn from the people we teach.

Make success contribute

A viable business can keep doing useful work. We also care about what its success makes possible for others.
