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.

With the threats posed by anthropogenic climate change now accepted as a key international issue, efforts to curb carbon dioxide emissions are becoming manifest around the world in spite of – and even as a response to – the global recession. But any such efforts may be in vain if the focus on carbon dioxide distracts from the need to curtail methane emissions, as Richard Douthwaite explains

Hotels typically take a heavy toll on the environment, with large amounts of energy used for heating, hot water, lighting, air conditioning and laundry, and huge amounts of waste being landfilled each year. John Hearne visited the Westport Woods Hotel and discovered a highly successful approach to reducing environmental impact that is also yielding substantial dividends in terms of cost savings and positive publicity

Invest NI has itself invested in a new headquarters in central Belfast that it hopes will be seen as a model for sustainable development, as Richard Linger, Sustainability Director, White Young Green Ireland explains.

Patrick Daly  highlights that the energy refurbishment of our existing housing stock must become a priority. Daly has undertaken a retrospective DEAP case study assessment of an example house and its BER ratings, with staggering results.

Any building, no matter how cold and draughty, no matter how remote, can be improved to world-class energy performance, as an upgraded and extended Donegal cottage dating back to the 1800s proves.

Landowners & Cement Producers Gain, Homebuyers & Taxpayers Suffer. By Richard Douthwaite

Set in the shadow of Macgillycuddy's Reeks, Killorglin, County Kerry is a dramatic and rugged location best known as a tourist destination and home to Puck Fair. It’s also home, however, to one of Ireland’s most successful companies, FEXCO, which has opened its new low-energy corporate headquarters in the town.

The worl­d has learned the hard way that our political leaders lacked the judgement and resolve to identify and address the problems which led to the recession. Richard Douthwaite argues that a similarly flawed judgement is evident in the assumption that the economy will recover, and advises on how to prepare for a future of global economic contraction.

Lenny Antonelli takes a look at some of the entrants of the 2009 Solar Decathlon, a competition that challenges university teams from around the world to design and build homes that capture the sun’s energy.
