This course is aimed at ALL building design and consulting professionals, including Architects and Engineers, Contractors and Builders.


9 half-day ‘live’ webinar modules led by Tomás O’Leary, from 9.00am (sharp) to 1.00pm on the dates below, followed by 3 days-equivalent e-learning that you’ll complete in your own time and at your own pace. 

Dates for the nine modules are listed below:

  • Tuesday, 23rd June 2020 - Module 1: Principles and Performance Standards
  • Wednesday, 24th June 2020 - Module 2: Highly Insulated & Thermal-Bridge-Free Envelopes
  • Thursday, 25th June 2020 - Module 3: Superior Airtightness & Vapour Control
  • Tuesday,  30th June 2020 - Module 4: Windows for Energy Balancing & Comfort
  • Wednesday, 1st July 2020 - Module 5: Delivering Indoor Air Quality through Active Ventilation
  • Thursday,  2nd July 2020 - Module 6: Next-generation Heating & Hot Water Systems
  • Tuesday, 7th July 2020 - Module 7: Economics, Quality Assurance & Certification
  • Wednesday, 8th July 2020 - Module 8: 3D Passive House Design Tool ‘designPH’
  • Thursday, 9th July 2020 - Module 9: Passive House Planning Package


The following format is used for this on-line course:

  • Series of nine ‘live’ (not recorded) webinar modules led by MosArt Director Tomás O’Leary.
  • Each module deals with a central theme of high performance buildings and consists of a four hour session from 9am to 1pm with a 20 minute coffee break half-way.
  • A second member of the MosArt training team, Dara McGowan, will be assisting in moderating the class and dealing with questions as they arise (just ‘raise your hand’ and Dara will be there to help).
  • We’re using what we feel is the best webinar tool available for professional and reliable online education in this field, namely GotoTraining. It allows us to issue quizzes and polls along the way to check your progress and also to issue additional materials throughout the course. 
  • At the end of each module, you’ll receive a link to watch a full video recording of that session. So, fear not if you have to put the cat out or if there’s yet another baking-emergency in the kitchen.   
  • The last two modules of the course deal with the cool Sketchup plug-in software ‘designPH’ used to design Passive House projects in 3-D as well as Passive House Planning Package energy modelling tool used to fine-tune your project. 
  • In addition to the on-line content, you’ll receive (by post) a hard-copy manual of all the slides so you can make your own notes as you progress. You’ll also receive a hard copy of the PHPP manual in the same package (the software used to design Passive House projects). 
  • Once the nine webinar modules have been completed, you will then complete our online self-guided exam preparation modules over a four week period leading up to the exam on 7th August.  
  • You’ll need to invest the equivalent of about three days on the on-line exam preparation course, so about a half-day per week should do it. 
  • The exam preparation course includes presentation videos, calculation exercises, true-false questions and a Passive House design assignment which you’ll scan/photograph and send to us for personalised review. We’ll be with you every step of the way.  
  • The programme culminates on 7th August with the Certified Passive House Designer exam, a 3-hour ‘open-book’ (bring all your notes!) exam.
  • On passing the exam, you’ll (a) receive a formal certificate from the German Passive House Institute and (b) find yourself listed on the global map and database of Certified Passive House Designers  (see map of designers here)

Five Key Benefits of Completing this Course

1. Appliance of Science to NZEB

Our Certified Passive House Designer course has just been updated to incorporate all you need to know about meeting NZEB, the ‘nearly zero energy building’ standard. The programme now includes the best-of-both, namely the scientific foundation that is Passive House and the legislative requirements of NZEB. You'll leave this programme not just knowing what is required for NZEB, but also how to deliver it in the most cost effective manner and taking great comfort in knowing that your project will deliver first time.

Come and join us, and draw on our experience of working in this field for 15 years.

2. NZEB Now Mandatory Across Europe

The nearly zero energy building standard, or NZEB for short, became mandatory in Ireland in 2019 (1st January for non-domestic projects, 1st November for residential). NZEB will require a 33% improvement in the energy efficiency of domestic construction. Whilst NZEB was first signalled in 2010, the construction sector in Ireland is largely ill-prepared. This course will put you in pole position to deliver cost effective NZEB and will cover the aspects of construction most impacted including ventilation, thermal bridging, airtightness and lots more. 

3. The NZEB Triple-Jump

There are three key ‘shocks’ in store for NZEB first-timers. These include (1) low U-values (for example 0.11 W/m2K in the roof and 0.13 W/m2K in the walls), (2) triple-glazed windows and doors and (3) whole house mechanical ventilation systems (for projects that achieve the super-easy target of 3 m3/hour.m2). So, say farewell to skinny cavity walls, double glazing and hole-in-wall ventilation!

Exploration of these three challenges forms the backbone of this training programme.

4. Run a Tighter-Ship

Passive House, first developed in 1992, has been delivering beyond-NZEB for almost 3 decades, involving triple-glazing and heat-recovery ventilation as standard. This will surprise you, but Passive House typically requires less insulation than NZEB. How can this be, you might ask? Well, it's all down to airtightness.

Passive House has always required super-tight buildings (approximately 0.6 m3/hr.m2) to protect the envelope, eliminate draughts and maximise efficiency of heat recovery ventilation. The airtightness levels required for NZEB, on the other hand, are less-onerous. But here's the trick - if you meet the Passive House levels of airtightness, you'll be rewarded in NZEB with reduced levels of insulation.

So, if you tighten up on air-sealing, you can ease back on insulation levels and reduce envelope costs. Clever application of tape is way-cheaper than low-U-value walls. Completion of this course will teach you all you need to know to deliver super-tight projects.

5. Our Experience

There's great comfort in using a tried, tested and verified delivery method for NZEB (in other words, Passive House). The Passive House was first delivered in Ireland in 2004 by our Director Tomás O'Leary who's been happy living there ever since. An in-depth monitoring study of this prototype home and of several other affordable homes by UCD has proven that it delivers both on energy efficiency and comfort, with zero performance gap. Our other Director Art McCormack followed suit more recently and commenced a step-by-step Passive House retrofit for his home in 2015 and has also experienced at first hand the incredible comforts delivered by the Passive approach.

Tomás is the lead instructor on this programme and he looks forward to sharing his trials and tribulations with you.

MosArt has delivered two Certified Passive House residential schemes since 2017, in Wexford and Dublin, both completed at cost parity and both performing exceptionally well. And in 2018, we designed Ireland's first commercial office buildings which meet both Passive House and higher than A1 standard. Coupled with this is our extensive experience with different construction systems and project types, including certifying in 2017 the world's tallest Passive House project, a 26 story apartment block in Manhattan. We are also very active on several (deep retrofits) multi-family projects in Dublin, reducing space heating demand by over 90%.
