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.

Nothing focuses the mind like a target. The growing impact of Building Energy Ratings (BER) is increasingly encouraging Irish people to aim for the highest energy rating they can. Patrick and Niamh Daly’s house in Mullingar takes this trend to the next level, using a myriad of sustainable green materials and technologies to become a net energy producer and go beyond the limit of the BER scale. John Hearne visited the nearly completed house to find out more.

When it comes to redeveloping old buildings, green designers face two choices: replace existing structures with modern, energy efficient buildings or refurbish and avoid the embodied energy and waste of demolition and new construction. Lenny Antonelli visited a redeveloped convent in Booterstown, County Dublin that combines the best of both approaches.

Richard Douthwaite explains how inadequate conventional energy generation is and reveals the potential that combined heat and power & energy service companies can offer.

As energy prices continue to rise, the Irish construction industry is moving into uncharted territory, where all elements that affect energy performance—from orientation, to building design, to specification, to standard of workmanship—are increasingly recognised as key concerns.

In a comparatively short time, district heating and cooling have emerged as an ideal sustainable solution for mixed use, residential, commercial and industrial developments. Far from being a new technology, district heating systems have been commonplace across Europe since the 1960s. Noel Walshe BE of district heating specialists Noel Walshe ltd explains what is required to deliver the most effective solution.

With the building of a new house in Greystones, County Wicklow, Ireland has become only the third country to feature the work of Frank Lloyd Wright. Jason Walsh visited the site to see if Wright's designs might just represent the kind of thinking required in today's energy-conscious buildings.

Ireland's largest passive house development to date, Shanganagh Castle, is proof that with proper planning and collaboration, delivering high density housing doesn’t mean compromising on quality or climate action – without increasing costs or causing delays.

As long term readers of Construct Ireland will recall, the mainstreaming in recent years of sustainable design and construction has been exemplified in many innovative local authority offices. John Hearne visited Aras Contae an Chláir, and discovered a building which attempts to holistically minimise environmental impact, with attention paid to more than just energy performance and carbon emissions.

Leading conservation architect Paul Arnold highlights the need for a sensitive approach when fire proofing heritage buildings, to ensure that, wherever possible, the best practicable fire safety is achieved along with, rather than at the expense of, preserving the building’s fabric
