Passivhaus - The 5 Key Principles

Passivhaus - The Energy Balance

In today’s modern living, having large windows to bring the outdoors in is encouraged where it can provide free heat from the winter sun.  Depending on the building’s orientation, large windows may need shading from the heat extremes of the summer months but this can be easily designed in using larger eaves that provide protection.  

The new era of home design that we discuss in our webpage is using techniques first introduced by the world-renowned American architect Frank Lloyd Wright, and we are seeing a massive global shift towards the “mid-century modern” revamp of Lloyd Wright’s Usonion homes, creating the new 21st Century “villa” home styling.

To Certify or Not

The Passivhaus Principles can be applied to any building, old or new, and any type of building whether residential o r commercial..  Many homes claim to be “eco” or “energy-efficient” but only Passivhaus  uses strict, measurable performance criteria - verified verified through independent testing.

No greenwashing.  Just guaranteed results.

Passivhaus certification isn’t just a building standard — it’s a conscious choice to prioritise quality, comfort, and sustainability at the highest level.  When you choose to build or retrofit to certified Passivhaus standards, you're making a decision to build it right the first time and future-proof your home, knowing that it will perform as it should through high quality building practices and design.  

Plus you get to have a really cool plaque by the front door!

You can of course simply follow the general principles to achieve a well-built and energy-efficient home.  The choice is yours.
