External examination

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects
Welcome to the archive of Construct Ireland, the award-winning Irish green building magazine which spawned Passive House Plus.
The feature articles in these archives span from 2003 to 2011, including case studies on hundreds of Irish sustainable buildings and dozens of investigative pieces on everything from green design and building methods, to the economic arguments for low energy construction.
While these articles appeared in an Irish publication, the vast majority of the content is relevant to our new audience in the UK and further afield. That said, readers from some regions should take care when reading some of the design advice - lots of south facing glazing in New Zealand may not be the wisest choice, for instance.
Dip in, and enjoy!

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects

An advocate of sustainable building long before it was fashionable, Bill Quigley of NuTech Renewables has subsequently seen the mainstreaming of sustainability at first hand, having input into substantial projects for Leahy Bros, MKN and GEDA Construction amongst others. In their latest project, NuTech are working with Wicklow County Council on a social housing scheme with impressively high energy performance targets to meet, as Quigley explains.

In April this year the first NSAI Agrément certificate was issued for the application of external insulation to existing dwellings. Joseph Little of leading green architects Joseph Little Architects used analysis from his practice’s Building Life Consultancy service to assess the certificate, and encountered issues which raised questions over whether it should have been issued in its current form.

Chris Croly from BDP outlines the low energy and renewable energy strategies used in University College Cork’s new Environmental Research Institute, a test bed for the design and performance of sustainable buildings, which is ideally suited to housing the 200+ environmental projects carried out by its researchers.


With 36 years experience in ecological architecture, Paul Leech of Gaia Ecotecture possesses a formidable knowledge of international green design. Fresh from picking up the best ecological building 2010 Lama award for the pioneering Navan Credit Union – and a favourable review in Prof George Baird’s Sustainable Buildings in Practice: What the Users Think - a global survey of green buildings - Leech describes a handful of inspirational green exemplar projects from around the world.

Nowhere demonstrates the need for a high-performance building envelope quite like a coastal site. John Hearne visited a cutting edge timber frame house overlooking Sligo Bay that was designed to achieve a highly insulated, air-tight and low embodied energy envelope whilst making the most of the spectacular vista.


Killiney is an area known for both its natural beauty and the desirability of the existing built environment. Jason Walsh visited two new houses in the exclusive south County Dublin village which show it as being at the forefront of the drive to create a lasting beauty.

Martin Murray, chairman of the Passive House Association of Ireland and founder of Martin Murray Architects, explains why the world’s leading energy efficiency standard is on the up in Ireland
