Passive House Construction

Why not build a passive house?

A Passive House makes efficient use of the sun, internal heat sources and heat recovery ventilation to such a standard that conventional heating systems are virtually rendered unnecessary. A Passive House enjoys a comfortable temperature winter or summer and much higher air quality than traditional construction.

Key features of a Passive house include;

  • INSULATION
    • Exceptional high level of thermal insulation.
    • Well insulated window frames and triple low-e glazing.
    • Thermal Bridge free construction, requiring a high level of design and drawing detailing.
    • Very low U-values
  • AIR-TIGHTNESS
    • Very high level of air-tightness
       
  • PASSIVE GAINS
    • High utilization of solar & internal gains
    • MHRV - Excellent air quality through efficient MHRV (Mechanical Heat Recovery Ventilation) system
    • Better building quality.


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.

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. Through careful design, thought and calculations a building can be created to require only the lowest amount of energy 15kWhr/m2 pa. 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.

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.
