If achieving eco buildings is challenging for new build, it is doubly so for renovation projects. Philip & Delphine Geoghegan of iCon Architecture & Uban Design describe a low impact renovation that balances these apparent tensions with great success.

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.

As more and more people upgrade their homes to make them more energy efficient, it’s crucial for them to consider installing some sort of ventilation system to keep them healthy. Astrid Madsen compares heat recovery ventilation to a relative newbie on the Irish market, demand controlled ventilation.

Ever since the seminal Agenda 21 was endorsed by 150 nations including Ireland in 1992, increasing lip service has been paid to sustainable development in everything from government policy to manufacturers’ claims. However, as John Hearne describes, in Tralee Town Council’s Rath Oraigh housing development, local action has been taken with not only local, but global benefits that embody the principles of sustainable development.

The Department of Education has made its commitment to energy efficiency and CO2 reduction clear in developing and bringing into practice targets for primary school design that aim for less than half of the accepted good practice in the field. Project coordinator John Dolan, Senior Engineer with the Department of Education explains how this approach works within normal Departmental budgetary limits to create school buildings that show the way ahead for building designers.

Thanks to the ESCo model, one school in Donegal has gone green, seen its heating bills reduced by 15% yet has not had to outlay one cent in capital expenditure. John Hearne investigates an emerging trend that is bringing low carbon energy into another realm.

Whilst great strides are being made in upgrading energy performance requirements under Part L of the Building Regulations, the issue of ventilation has remained largely ignored by legislators for years, leaving designers with antiquated standards to work to. At its worst, efforts to air-tighten and increase the insulation of homes is being undermined by the absurd practice of knocking holes in walls. John Hearne looks into what changes need to be made to modernise Part F.

On 7 June 2011 environment minister Phil Hogan TD signed the latest changes to Part L of the building regulations into law, which will make it mandatory for all new homes to be 60% more energy efficient than the standards at the peak of the construction boom. Jeff Colley sheds some light on the key changes

Solearth partner & Éasca board member Mike Haslam profiles five inspiring English and US projects that share a similarly considered green design approach.

Creating the right comfort in buildings for elderly people involves ensuring a warm internal environment, which typically results in high energy consumption. John Hearne visited the new Castle Gardens Retirement Village as it approached completion and found a project that combines complimentary low energy technologies, materials and design to deliver high levels of comfort whilst also keeping running costs, energy consumption and carbon emissions low
