Much of the housing built around Dublin over the last forty years has been built of single-leaf nine-inch hollow block construction – which are both notoriously energy inefficient and extremely difficult to insulate effectively without causing damp problems. Lenny Antonelli visited a hollow block house which has been ecologically renovated to protect occupant health whilst shooting to the top of the energy rating scale.

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

As long term readers of Construct Ireland will recall, the mainstreaming in recent years of sustainable design and construction has been exemplified in many innovative local authority offices. John Hearne visited Aras Contae an Chláir, and discovered a building which attempts to holistically minimise environmental impact, with attention paid to more than just energy performance and carbon emissions.

A new development in the historic town of Thomastown, County Kilkenny brings the cutting edge of green innovation into a setting known for its medieval heritage. John Hearne visited the site, where a commitment to the environment is evident in sustainable design combined with everything from airtight detailing to technologies such as factory insulated timber frame, low energy windows, solar thermal, photovoltaic and heat recovery ventilation

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures. 

Thanks to the ESCo model, one school in Donegal has gone green, seen its heating bills reduced by 15% yet has not had to outlay one cent in capital expenditure. John Hearne investigates an emerging trend that is bringing low carbon energy into another realm.

Responding to the Department of Communications, Marine & Natural Resources’ Green Paper “Towards a Sustainable Energy Future for Ireland”, Mark Coyne, Technical Director of Dalkia Ireland, outlines the challenges and responses to the three main pillars of the Green Paper – sustainability, competitiveness and security of supply.

As energy prices continue to rise, the Irish construction industry is moving into uncharted territory, where all elements that affect energy performance—from orientation, to building design, to specification, to standard of workmanship—are increasingly recognised as key concerns.

Brian Homan, Joint Managing Director of leading consulting engineers Homan O’Brien Associates describes a nursing home currently being built that is adopting a sustainable building approach to deliver healthy, comfortable accommodation at low running costs.

Lenny Antonelli visited a recently refurbished complex of social housing flats in Galway city that has combined excellence in urban regeneration with energy efficiency and major strides towards sustainability
