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

On Tuesday the 15th of March a passive house, a house that does not need to be heated, was built a few miles outside of Galway. The brain child of Lars Pettersson of Galway based Scandinavian Homes Ltd, it is believed to be the world’s first standardized and factory made passive house.

Building a visitor centre at such an evocative site as the Cliffs of Moher, one of Ireland’s greatest tourist attractions must have been something of a challenge. By attempting to cater for visitors, the centre could so easily have ruined the rugged, barren landscape which makes people visit in the first place. John Hearne visited the new interpretive centre to discover a building which addresses this problem by becoming part of the landscape, whilst using eco technologies to reduce the building’s strain on the broader environment.

Until recently the York Street flats had been a living legacy of failed past approaches to social housing – a slum of mainly north-facing flats dating from Victorian times, and poorly rebuilt in the year Ireland became a republic, 1949. John Hearne visited the recently redeveloped York Street and found a thoroughly sustainable set of buildings that should inspire thoughts of future progress rather than past failings.

When the two worlds of heritage and development collide opinions frequently become polarised and fraught with difficulty. There are few more vexed issues, as Tim Carey, Heritage Officer with Dun Laoghaire Rathdown County Council reveals

Buildings that are designed or refurbished to use little energy all too often fail to deliver the expected performance, if the building occupants aren’t able to use the building as intended. John Hearne reveals the crucial role that user-friendly heating controls play in ensuring that a theoretically low energy building delivers the expected results.

Some buildings, by their nature, tend to have larger energy requirements. Occupied around the clock, with occupants who feel the cold, nursing homes are a case in point. John Hearne visited a north Dublin building where a range of different sustainable technologies operate in tandem to deliver the residents’ heating and hot water requirements

As the organisation entrusted by OECD countries to predict future global energy supplies, the International Energy Agency’s projections have significant impact on energy policy around the world. IEA officials recently told The Guardian that the organisation’s figures on oil supply had been inflated and that oil peak is happening. Richard Douthwaite assesses the fall out

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.

Lime-hemp is developing as a bio composite construction material with serious ecological and energy advantages. Patrick Daly, lecturer in Environmental Design at DIT Bolton St. asks if this is the environmental material of the future and explores its mainstreaming potential.
