In spite of the obvious emergence of technologies and design approaches to reduce the impact of new build, environmental standards remained poor throughout the duration of the housing boom. Now, a unique combination of political will, smart incentives, and a new market of informed and empowered buyers may be about to change that, writes Lenny Antonelli

The advent of central heating improved the comfort of life for countless Irish people over the past century, but as energy efficient building grows, some pioneering homeowners think they can live without it. What’s life like for them?

A new house in west Cork offers a green vision for the future of Irish home building: not only is it A-rated, airtight and highly energy efficient, it’s built with ecological materials that are manufactured in Ireland too.

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

Why Ireland may default on debts, & what to do next

Heat recovery ventilation, a technology that has become a standard building application in Scandinavian countries, is rapidly gaining recognition in Ireland as a solution to both problems.

As our recognition of the problems of dwindling fossil fuel supplies and climate change grows, the need to reduce the energy consumption and carbon emissions of our homes becomes increasingly apparent. Leading energy consultant Patrick Waterfield describes why and how we should switch to zero heating homes.

Earlier this summer SEI announced that, from December, external wall insulation systems must have Irish Agrément certification to be eligible for support under the Home Energy Saving scheme. But many in the green building sector are critical of the decision, and some are questioning the value and purpose of Agrément. Lenny Antonelli reports.

The desire for better insulated, more environmentally friendly homes is driving ever more Irish self-builders to investigate alternatives to traditional block building. Jason Walsh visited a contemporary style factory-built timber frame house built in County Waterford in 2005.

One thing householders don't want to fail is their wastewater treatment system – the pollution, the health hazard, the cost and not least the embarrassment factor are all potentially serious. And yet, one wastewater treatment system provider says that such failures are very likely. As Jason Walsh asks, is he right?
