With an economy fuelled by a government approach to planning that many people equate to a road building and house building free for all, it should come as no surprise that quality of life suffers

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.

The vast majority of Irish buildings are in need of substantial energy upgrade work. Given the difficult economic conditions and low public awareness of the cost, comfort and health benefits of a well-designed energy renovation, the notion of upgrading most Irish buildings is a considerable challenge. However, as Lenny Antonelli explains, new ideas are emerging that could stimulate energy upgrade work on an unprecedented scale.

There are surprisingly few truly iconic buildings, structures that dominate their environs, not to mention the country's intellectual landscape. Halla Chontae Chorcai, Cork County Hall, is one such building. Construct Ireland's Jason Walsh visited to find out about the building's environmental credentials.

BRENDAN HOWLIN, T.D., Minister for the Environment (1994-1997) reflects on the blueprints, policies, and commitments that emerged from the Rio Earth Summit and looks at how far we have progressed since

Since the announcement last September by the Minister for the Environment of substantial improvements to be made under Part L of the Building Regulations, speculation has been rife in the construction industry about what the details of the updated regulations would entail. Jeff Colley examines some of the key parts of a regulatory improvement that will help the Irish construction industry to modernise and meet the demands of a rapidly changing world.

Ambitious companies in the Irish sustainable building sector should look to the US, says Century Homes founder Gerry McCaughey. As chief executive of LA-based green building business consultancy Infineco, McCaughey is witnessing first-hand how the land of opportunity is waking up to green construction.

In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible

As policy makers start to set mandatory low energy and renewable energy requirements as conditions of planning, the ability of the construction industry to find sound low-cost ways of achieving the new standards is becoming a key factor. John Corless speaks to leading sustainable building consultant Jay Stuart of Delap & Waller EcoCo and Paul Gilmartin of Ecobead to discover an approach with enormous potential for en-masse usage.

Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.
