A half-day session 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’!
Neil Turner, Technical Sales Manager 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. Joe Fitzgerald, Technical Support Engineer at Ecological Building Systems, will then provide a case study on the building of a new home in Ireland to Passivhaus levels of performance. Finally, the Ecological team have filmed their airtightness practical session, so you will be able to watch how to install membranes, tapes and seals with live commentary and Q&A provided by trainer Ilias Igoumenidis, Technical Support Engineer at Ecological Building Systems.
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
Joe will present a case study on colleague Niall's home. 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. Joe will outline how airtightness was delivered on this new home from design concept to completion and key lessons learnt along the journey.

About the trainers
Joe Fitzgerald is Technical Support Engineer & NSAI Approved Thermal Modeller at Ecological Building Systems.
Joe is a trained Energy Manager and graduated from Athlone I.T with an Honour’s Degree in Sustainable Construction & Energy Management. After this he went on to complete a Post Graduate Diploma in Green Engineering and joined Ecological shortly after.
In addition to his academic studies, Joe has also spent many years as a tradesman and has completed the Passive House Contractor exam. Most recently, Joe became an NSAI approved Thermal Modeller after completing his examination in Dublin Technological University and is now certified to carry out thermal bridge assessments to evaluate heat loss in buildings.
Ilias Igoumenidis is Technical Support Engineer at Ecological Building Systems. Born and raised in Greece, Ilias graduated from the Polytechnic school of Civil Engineers of Patras University and for many years ran his own Design and Construction company prior to moving to the UK. Since 2013, he has been heavily involved with low energy consumption in building projects. He was the first person in the Hellenic Passive House Institute to gain the International Certification of a Certified Passive House Designer. Ilias played a significant part of the first Certified Passive House project [Enerphit] in the south eastern Mediterranean area “Passivistas”. Recent projects that Ilias has been involved with include:
- Agar Grove, London Borough of Camden, 500 affordable homes for new and existing tenants, putting energy performance and fuel poverty top of the agenda, Hawkins\Brown Architects.
- Glen Cottage, Allonby, Cumbria, internal and external renovation of solid stone property with Diathonite Evolution system.
- St Leonards, Chelsea, London, internal renovation with Diathonite Evolution and Calsitherm climate board systems, Richard Bayliss, Le Lay Architects & Harry Paticas, Arboreal Architecture.
Neil Turner is Technical Sales Manager at Ecological Building Systems. A former competent person of the BBA/TIMSA U-Value and Condensation Risk Calculation Competency Scheme, who has been involved in developing CEN (Comité Européen de Normalisation) European standards, Neil has extensive experience in the building products sector. Neil advises architects, contractors and timber frame specialists on the specification of sustainable insulation products and has been involved in numerous sustainable projects throughout the UK.
Recent projects that Neil has been involved with include:
- Bristol City Council affordable Passivhaus housing scheme with pro clima systems, Halstatt Construction and Gale & Snowden Architects
