What is a Passive House?
A Passive House enjoys a comfortable temperature winter or summer and much higher air quality than traditional construction.
A Passive House is a healthier house that controls dust and pollen associated with hay fever and other allergies. A Passive House controls humidity, eliminates mould and condensation which is associated with asthma and other respiratory illnesses. A Passive House does not have a specific construction method and can be constructed from any construction materials, even concrete!
What is so special about a Passive House?
2. Well insulated window frames and triple low-e glazing.
3. Thermal Bridge free construction, requiring a high level of design and drawing detailing.
4. Airtight building envelope – no draughts.
5. Healthier air quality with highly efficient heat recovery ventilation.
6. Better building quality.
Advantages of a Passive House
2. Healthier living environment, with dust and pollen reduction, controlled humidity and free of mould and condensation.
3. High level of comfort – constant indoor temperature.
4. Greener and more environmentally friendly homes due to the huge reduction in CO2 emissions associated with space heating over the lifetime of the house.
Facts and Figures
A Passive House uses no more than about 1.5 litres of heating oil per year for every square metre of living space. At today’s energy prices this equates to circa €1.25/m2 per year in space heating costs. This is approximately a tenth of a traditionally constructed house to current standards.

The Passive House Technical Criteria
The design criteria set out by the Passive House Institute includes the following:
1. Specific Space Heat Demand: Max. 15Kwh/m2.year.
2. Pressurisation Test Results (n50): Max. 0.6 airchanges/hour
3. Entire specific Primary Energy Demand: Max. 120Kwh/m2.year
