Construct Ireland investigates what measures the Irish government is undertaking to actively encourage the homeowner to switch to non-polluting renewable energy sources.

After a long struggle to build their home, Karen and Steve Ward finally got their wish — an energy efficient, timber frame house that boasts a palette of healthy and ecological materials and a fully renewable heating system.

As fears grow amongst climate scientists that the world may be close to reaching a tipping point leading to runaway global warming, there’s a growing recognition that the forthcoming UN climate conference in Copenhagen must deliver dramatic and binding targets to cut carbon. According to Richard Douthwaite, the talks are unlikely to deliver sufficiently meaningful action.

A framework for strategic sustainability is essential if we’re serious about greening the Irish built environment.
According to green architect Pat Barry, we should look no further than The Natural Step.

In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack

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.

As interest in sustainable building continues to escalate, Construct Ireland is increasingly unearthing buildings that betray an ambition to break new ground under a plethora of green criteria. John Hearne visited one such house in County Louth, and found a project driven by passive house and BER scale-topping ambitions combined with on-site energy and water supply strategies and a commitment to the use of green materials

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.

The Passive House standard, an internationally renowned approach to building that negates the need for conventional heating, has attracted considerable interest in Ireland recently as energy prices continue to rise. Vivienne Brophy, Dr Irena Kondratenko, Patxi Hernandez and Kevin Burke of UCD’s Energy Research Group look at the effect this approach could have on cutting Ireland’s energy consumption and CO2 emissions.
