“Electrical waste is one of the fastest growing waste streams in Ireland. It is a source of valuable materials which can readily be recycled and which we must divert from landfill”, Minister Martin Cullen, 19 February 2003.

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

Designing a low-energy public building with passive ventilation and lighting in mind is one thing – making it fit seamlessly into a rural wetland environment is quite another. Lenny Antonelli visited the award-winning Ballybay Wetlands Centre in County Monaghan - a closed-panel timber frame structure designed to sit softly on the surrounding landscape.

A new timber frame house in the Wicklow hills is arguably the most airtight building ever built in Ireland, boasting wood fibre external insulation and an obsessive attention to sealing

Designing sustainable buildings doesn’t always mean hi-tech solutions. From green roofs to living walls to constructed wetlands, sometimes it’s just a matter of embracing natural solutions. Lenny Antonelli investigates the emerging technologies and designs that use nature to improve the performance of buildings.

Due to the ill-considered productivity of the house building industry towards the tail end of the economic boom, Ireland is now saddled with hundreds of thousands of vacant homes in various states of completion. Structural engineer Sadhbh Ní Hógáin, currently writing her thesis for a masters architectural degree in advanced environmental and energy studies at the Centre for Alternative Technology, looks at the options Ireland has to address the problem.

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

Interhabs, a company who build to the highly energy efficient Canadian Super E programme, have recently entered the Irish house building market.
Jeff Colley speaks to Ronan Long , General Manager of Interhabs Ireland, about the reasons why he believes Interhabs will bring energy efficient, comfortable, healthy homes to people across Ireland

As Building Regulations tighten on carbon emissions, energy reduction and mandatory renewable energy targets, the task for designers becomes harder and harder. Bobby Gilbert of Bobby Gilbert and Associates explains how a new design tool is making sustainable design easier.

A new extension to the EPA's headquarters in Wexford lives up to the organisation's aim of environmental protection, boasting passive ventilation and lighting, a host of green technologies and a sustainable approach to landscaping.
