It also boasts a masterfully crafted timber frame structure with one of the best airtightness results this magazine has ever published.

During a speech last year Theresa May challenged the construction industry to halve the energy use of new buildings, and to halve the cost of retrofit. But we already know how to meet these challenges, writes Peter Rickaby, and much more difficult tasks lie ahead.

In his latest column on the history of low energy building in the 20th century, Dr Marc Ó Riain charts the surprisingly fascinating history of double glazing.

Following on from their previous incarnation, the Isover Energy Efficiency Awards, the new Isover Awards will be open to both contractors and architects/specification professionals, and seek to celebrate excellence in energy efficient building and design.

The first phase of development is now complete at Clog Na Léinn, a new scheme of A1-rated ‘zero energy’ homes in Collinstown, Co Westmeath. Developed and built by NJ Doyne and designed by architect Louis Peppard, the first 13 houses are now finished, with the first residents moving in just as Passive House Plus went to print.
