A new timber frame house in the Wicklow hills is arguably the most airtight building ever built in Ireland, boasting wood fibre external insulation and an obsessive attention to sealing

Since the announcement last September by the Minister for the Environment of substantial improvements to be made under Part L of the Building Regulations, speculation has been rife in the construction industry about what the details of the updated regulations would entail. Jeff Colley examines some of the key parts of a regulatory improvement that will help the Irish construction industry to modernise and meet the demands of a rapidly changing world.

Richard Douthwaite explains why the bailout may turn out to be a gift to Ireland, and offers some advice for dealing with a default.

Ireland — along with much of the western world — relies on the International Energy Agency‘s oil production forecasts. But are they reliable, asks Lenny Antonelli?

There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.

Achieving building regulations compliance and a good energy rating is one thing. Delivering a genuinely low energy building is quite another. A new scheme by one of Ireland’s most decorated developers may help show the market a way forward.

A log bungalow in rural Meath has been extended and given a total energy upgrade – and wood is at the heart of the renovation, with a timber frame extension and external insulation system along with a fresh log finish.

There are surprisingly few truly iconic buildings, structures that dominate their environs, not to mention the country's intellectual landscape. Halla Chontae Chorcai, Cork County Hall, is one such building. Construct Ireland's Jason Walsh visited to find out about the building's environmental credentials.
