Seminar Title: NZEB Build Brings Family In From The Cold

Seminar Description: This is Arthur’s story of the planning, design and project management of his own Self Build. Arthur gives a frank account of the challenges involved in the build. He also talks about working with his architect, energy assessor, structural engineer and Xtratherm’s Technical team in his effort to achieve higher thermal performance and lower carbon emissions in his A2 Rated dream home.

Speaker Profile: Having previously lived in a semi-detached home built during the Celtic Tiger years, and more recently in a 1960s farmhouse, Arthur was very aware of what he wanted from a Self Build. He has researched extensively on Self Build and over the past 3 years, he and his wife Aoife have undertaken a build, which has become their forever home. Mark Magennis is the Head of the Technical Team at Xtratherm – a veteran of the construction industry with 18+ years’ experience working with insulation solutions. Mark was the first person in Ireland to be assessed and certified under the NSAI thermal modelling competency scheme, using the most comprehensive 3D software available.
