What Passive House is
The term Passive House or Passiv Haus suggests a very thorough and precise detailed design of a building with an energy demand 90% lower than most buildings. It is important to emphasise that ‘Passive House’ defines an energy standard and a set of principles. The construction method and the design methodology are not predetermined.
For more information and answers to many of your questions, please see our FAQ.

What PHAI is: Mission
The Passive House Association of Ireland (PHAI) is a catalyst for the increased awareness of the opportunities and benefits of low energy design based on the Passive House principles, across the Irish construction industry as a whole. Passive House design is seen as a specifically proven successful way of designing such buildings.
The Mission of the PHAI is to promote, educate and facilitate, so as to develop a strong identity, understanding and demand for the Passive House concept.
PHAI is an Affiliated Association with the International Passive House Association.
The Association is non-profit-making in so far that all membership fees collected go toward the promotion of the Passive House Principles in their many varied forms.

“I am delighted to see the continued expansion and understanding of the Passive House Principles of design and construction throughout Ireland. We must continually inform and educate ourselves in building to low energy requirements and, where possible, certified to Passive House Institute standards. I wish the ‘Passive House Association of Ireland’, the very best in it’s efforts in this regard.” – Duncan Stewart
“The term ‘passive house’ – arguably the leading low energy building approach in the world – has entered the lexicon for anyone looking to build in Ireland over the last few years. This does not mean that everyone understands the term in full – many people remain unaware that it’s a specific, rigorous building standard, and mistakenly use it as a short hand for energy efficient building and use of renewables. The Passive House Association of Ireland will greatly help to correct this, showing Irish people the benefits in terms of comfort, energy and environment gained by building to the Passive House standard.” – Jeff Colley, Editor, Passive House Plus
