ES3: Achieving Airtightness, Why and How: The need for joined up thinking for joined up building! - Online
A half-day seminar exploring the theory and practice of achieving higher levels of airtightness - how to ‘build tight and ventilate right’
Buildings that achieve higher levels of airtightness tend to also be built and executed to a much higher quality level. While airtightness is essential to ensure thermal insulation performs to its optimum and to reduce condensation risk, it must also be combined with an effective ventilation strategy, be it by passive or mechanical means.
At its most basic, airtightness aims to eliminate any unintended gaps or cracks in the external fabric of the building. Ventilation focuses on replacing the stale indoor air with fresh outdoor air to meet the occupant’s needs. The key is to ‘build tight and ventilate right’!
Fintan Wallace, Architectural Technologist with Ecological Building Systems, will provide a presentation outlining why airtightness is now recognised as a key element in realising higher performance more durable healthy buildings. Niall Crosson, Group Technical Manager at Ecological Building Systems, will then provide a case study on the building of his new home in Ireland to Passivhaus levels of performance. Finally, the Ecological team will finish up by assessing key junctions for airtightness on specific details sent in by the audience prior to the training day.
More demanding building regulations not only require an improvement in individual skills but require a change in attitude to working collectively with a focused, co-operative approach to achieve compliance with regulations. Higher performing buildings, be it new build or retrofit, require good site control and communication between all trades. The production of truly low energy buildings require diligent attention to detail and co-operation between all trades involved in the construction and renovation processes. All trades should view the house as a system, rather than the sum of its parts. Trades must work as a team. All works must be co-ordinated.
The current fractured approach to building must be changed to a systems-based approach to building, in a similar manner to Passivhaus building principles and the quality standards, which are often observed on low energy or Passivhaus projects in the UK and Germany.

More about the Case Study
After almost 2 decades providing technical guidance with Ecological Building Systems, Niall finally had the opportunity to build his own family home in Cavan, Ireland. Using natural thermal insulation materials and a range of airtightness solutions Niall aimed to achieve Passivhaus levels of performance and certification, while at the same time accommodate a design which was “acceptable” to all his family. This meant, adjustments and amendments to what was initially a relatively simple design, to more intricate details to meet the demanding airtightness, insulation and ventilation requirements of Passivhaus. Niall will outline how airtightness was delivered on his new home from design concept to completion and key lessons learnt along the journey.
This seminar is past of a series of 3 events on IWI, Roofs Walls & Floors, and Achieving airtighness. "A fabric first approach to healthier more energy efficient new and existing buildings."
Each event can be attended as a stand alone course, or if attending the whole series they will complement each other.
Delegates who are attending the training session on Achieving Airtightness on 3rd June will be given a unique opportunity to ask our speakers specific airtightness and windtightness queries. If you are interested in this, please email any relevant drawings, sketch, PDF or CAD format or photographs, your query may relate to critical detailing recommendations in retrofit and newbuild, masonry, timber frame or CLT construction.
The technical team at Ecological will then share their recommendations on how to approach it, practical suggestions and product solutions to use: Send your e mail to firstname.lastname@example.org by noon on Thursday 28th May and add GBS Event to the title. Please note that we cannot respond to any information sent after this time, if there are numerous submissions, our speakers may choose similar themes and will answer as many as possible on the day but Ecological can follow up any specific queries on a one to one basis following the session. As this is an interactive session delegates must be willing to share their details in an open forum where joint learning outcomes may be attained.

Fintan is an Architectural Technologist at Ecological Building Systems. Graduating from Dublin Institute of Technology in 2011 with a B.Sc (Hons) in Architectural Technology, it was here in D.I.T’s Bolton Street where Fintan developed a strong interest in low energy and Passivhaus design. From here he continued his studies becoming both a Certified European Passivhaus designer and tradesperson. Fintan has travelled to Baden Württemberg in Germany to study passive housing and sustainable energy technology, gaining significant knowledge regarding the use of natural insulations in timber frame and solid wall constructions. Latterly Fintan has been involved extensively in a deep energy retrofit of a property to the Enerphit standard in the west of Ireland. Recent projects that Fintan has been involved with include:
- Vitsoe, CLT Factory, Gutex and pro clima systems, Waugh Thistleton Architects.
- Chelsea Barracks refurbishment, pro clima systems.
- Lower Royd Farm, Passivhaus refurbishment with Diathonite.
