About two dozen builders and design professionals met in Dublin on 20 January to discuss strategies and real-life examples of thermal bridging issues in construction. The session was led by Andy Lundberg of Passivate and lecturer at DIT.

Andy shared advice and lessons learned from a number of low-energy projects, and talked about the importance of dealing with thermal bridging from design through to construction.

Discussion of the design process

Continuous insulation and airtightness were critical concepts that were explained through theory and real site examples, of both best practice and poor workmanship.

Wind tightness and airtightness are both important

Steps to thermal bridge-free construction

Ultimately, the final suggestion from Andy is that design and construction professionals work together to make the process outlined below a reality on every project and site.

1. Designers understand principles of good fabric design and use specialist consultants where needed.
2. High quality of information delivered to site.
3. Site trades adequately educated on principles of good building fabric design…they know WHAT to do and WHY to do it.
4. Value engineering on site supported by informed decisions or analysis.
5. High standard building quality delivered to clients.

The next Dublin briefing covers the importance of properly designed and installed ventilation systems is essential to maintain energy efficiency within a building and to provide a healthy environment for the occupiers, especially with modern air tight homes. The fundamental principle of low energy building is to build tight and ventilate right. This briefing and discussion focuses on appropriate ventilation systems and their installation.
