The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains

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.

As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

Building a visitor centre at such an evocative site as the Cliffs of Moher, one of Ireland’s greatest tourist attractions must have been something of a challenge. By attempting to cater for visitors, the centre could so easily have ruined the rugged, barren landscape which makes people visit in the first place. John Hearne visited the new interpretive centre to discover a building which addresses this problem by becoming part of the landscape, whilst using eco technologies to reduce the building’s strain on the broader environment.

The notion that curbing CO2 emissions would damage economic growth has been used as an excuse from developed countries such as the USA not to switch from fossil fuels to renewable energy. However, as Richard Douthwaite reveals, the people of Austrian town Güssing are discovering firsthand that this couldn’t be further from the truth.

Geothermal heating is being specified by everyone from self-builders to developers to local authorities in increasing frequency across Ireland. As a relatively new technology in Ireland, it is crucial that anyone considering a geothermal system knows what they are getting into, to ensure an efficient, reliable heating source.

With over 20 years experience in this field in Ireland, Dr Paul Sikora, Vice Chairman of the Geothermal Association of Ireland explains what issues to be aware of when considering geothermal, from site suitability, to what to look for from suppliers and installers.

Recent allegations that a single leaf timber frame development in Leitrim was forced to incorporate an outer layer of blockwork in spite of no such requirement in the Building Regulations or by the local authority in question suggests that something is seriously amiss, as Frank Coles explains.
