Passive House Systems

Products for Low Energy Buildings

Our Services

We at Passive House Systems have been involved in a range of airtight house construction products and services in Ireland for improving the energy performance in new-builds and existing houses since 2008.

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. 

Learn more – 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.

Learn More – A member of our team can call to your site to help specify the right products to reach your project goals. Whether your are installing an airtightness, solar pv, ventilation or heat pump system have get in touch with us to ensure the best results. 

Learn More – We can make sure you have the skills you need to become an airtightness installer. We offer a training service, that gives you all the necessary tools to meet airtightness building regulation standards. We offer a hands on, one day, training course giving you all the theoretical knowledge, along with practical installation demonstration. 

Learn More – 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.

Learn More – Sound Testing is a service describing acceptable level of sound between two spaces, that are separated by a dividing element and outlining the impact sound insulation (basing on the Technical Guidance Document ‘E’ of the Building Regulations in Ireland).

Learn More – 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.
