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

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects

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.

Richard Douthwaite explains how inadequate conventional energy generation is and reveals the potential that combined heat and power & energy service companies can offer.

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.

Earlier this year constructireland.ie broke the news of the introduction of the pilot Home Energy Saving Scheme, a new grant funding programme designed to stimulate the en masse refurbishment of Ireland’s poorly performing existing housing stock. John Hearne travelled to one of the pilot areas to see how the scheme is working on the ground, and discover how the scheme is developing.

With money leaving local economies across Ireland to service debt and significant drops in local authority revenues, towns such as Dundalk, Ennis and Kilkenny are investigating the possibility of bringing in electronic currencies to keep money circulating locally, as Richard Douthwaite reveals.

Based on past form, the Department of the Environment officials could be forgiven for bracing themselves for a construction industry backlash in response to the proposed changes for Part L of the building regulations which aim to both improve energy efficiency and reduce carbon emissions by 40%, whilst also introducing mandatory renewable energy and air tightness requirements. Jeff Colley outlines why, for reasons of self interest alone it’s very much in the industry’s interests to embrace the new regulations rather than attempt to resist change.

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

The previous edition of Construct Ireland featured an article by leading green architect Joseph Little analysing the insulated dry-lined blockwork walls typical of many homes in Irish housing estates, looking particularly at moisture movement within the external walls. Continuing on from that article, Little looks at the implications of several ways of insulating houses of hollow block construction.
