Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.

The desire for better insulated, more environmentally friendly homes is driving ever more Irish self-builders to investigate alternatives to traditional block building. Jason Walsh visited a contemporary style factory-built timber frame house built in County Waterford in 2005.

Converting attic space can provide a relatively low cost means of increasing useable space, relative to the more arduous options of extending, or moving to a larger building. Duncan Stewart speaks to Construct Ireland about how best to approach Attic Conversions.

Due to the ill-considered productivity of the house building industry towards the tail end of the economic boom, Ireland is now saddled with hundreds of thousands of vacant homes in various states of completion. Structural engineer Sadhbh Ní Hógáin, currently writing her thesis for a masters architectural degree in advanced environmental and energy studies at the Centre for Alternative Technology, looks at the options Ireland has to address the problem.

The vast majority of Irish buildings are in need of substantial energy upgrade work. Given the difficult economic conditions and low public awareness of the cost, comfort and health benefits of a well-designed energy renovation, the notion of upgrading most Irish buildings is a considerable challenge. However, as Lenny Antonelli explains, new ideas are emerging that could stimulate energy upgrade work on an unprecedented scale.

In many ways local authorities have become some of Ireland’s most progressive developers. Jason Walsh visited Ardee, County Louth to look at the latest in a long line of new civic offices that are redefining local government in sustainable terms.

Located in Oldtown, a hard to find country town in County Dublin, is a stunning new one-off house that not only manages to bring open-plan living to rural life, but also meets the onerous passive house standards using low impact materials. Jason Walsh visited the site as the house neared completion to find out more, an opportunity that Construct Ireland couldn’t pass up

A new development in County Westmeath answers a nagging question about district heating: how to make it financially viable when it services energy efficient buildings. Lenny Antonelli visited a housing estate that combines low energy design with an innovative district heating system and ecological timber frame construction

A new development at Grange Lough, Rosslare, reveals that passive houses can be made Irish – both in terms of what they’re built with, and how they look.
