The Carroll’s cigarette factory in Dundalk has been reborn as an avant garde exemplar of wind energy storage and an ingenious approach to integrated heating, ventilation and cooling, as sustainable design expert Chris Croly of BDP explains.

A typical Irish bungalow built in the early 1990s has been transformed with a green-tinted extension built in the spirit of modernism. Jason Walsh visited Enniskerry, County Wicklow to see how the old and the new were integrated

Eco architects Solearth expand their highly impressive portfolio with deep green design at Castle Espie Wetlands and Wildfowl centre

Local authorities upgraded hundreds of houses last year under a €20m government scheme, and the Department of Environment has doubled funding for 2010. With local energy agencies playing a key role on the ground, the programme offers vital lessons for keeping quality high in energy retrofit schemes. Words: Lenny Antonelli

Ireland's first passive house development emerged as the big winner at the inaugural Isover Energy Efficiency Awards in February. We look at the winner and other finalists

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

Achieving building regulations compliance and a good energy rating is one thing. Delivering a genuinely low energy building is quite another. A new scheme by one of Ireland’s most decorated developers may help show the market a way forward.

When it comes to redeveloping old buildings, green designers face two choices: replace existing structures with modern, energy efficient buildings or refurbish and avoid the embodied energy and waste of demolition and new construction. Lenny Antonelli visited a redeveloped convent in Booterstown, County Dublin that combines the best of both approaches.

As Ireland struggles to meet its commitments to reducing CO2 emissions in accordance with the Kyoto Protocol, the renewable energy sector continues to flourish as wind farms rapidly develop and solar energy becomes increasingly viable
