Passive House Systems

Products for Low Energy Buildings

Airtightness & Ventilation Specialists

Passive House Systems is a leading supplier of energy conserving products used in domestic new-build and retrofit building projects. We supply a range of Airtightness, Ventilation and Wind Tightness products designed to meet the continuously evolving requirements of the construction industry and energy conscious homeowners.

Headquartered in Cork, with engineering, procurement, sales and logistical bases in Ireland, UK, Germany and Poland, we are well placed to provide leading product technologies and supporting services.

To compliment the excellent products we supply, we offer the following services to support the successful product system design, product selection, installation and, where applicable, maintenance. 

We can design your ventilation system to meeting Irish building regulations and to ensure a healthy indoor air quality:

  • Heat Recovery & Ventilation (HRV)
  • Continuous Mechanical Extract Ventilation (cMEV)
  • Positive Input Ventilation (PIV)

Our design is done by our own in-house engineers with state of art design packages, with some input from external fire compliance engineers and equipment manufacturers. These people don’t just sit at desks, they are also involved in on-site consultations and commissioning.

Passive House Systems have been testing buildings since 2007. Air tightness testing is the measurement of airflow through the building envelope. Air leakages are an issue for many existing buildings, as air tightness levels were not a requirement in building regulations.

Passive House Systems advises its customers using WUFI® software, which is fully compatible with BS EN 15026, and dynamically predicts moisture movement and storage as well as condensation for each location. Using WUFI® enables architects, designers and developers to identify the likelihood and risks of condensation, and enables designs to be optimised for longevity of the building fabric, and for the health and wellbeing of the buildings occupants.
