With 36 years experience in ecological architecture, Paul Leech of Gaia Ecotecture possesses a formidable knowledge of international green design. Fresh from picking up the best ecological building 2010 Lama award for the pioneering Navan Credit Union  – and a favourable review in Prof George Baird’s Sustainable Buildings in Practice: What the Users Think - a global survey of green buildings - Leech describes a handful of inspirational green exemplar projects from around the world.

As the main attraction at the Spring House and Garden Show in the RDS earlier this year, the “Eco House” claimed to offer the house buying public an entirely ecologically sound new home, with considerations for energy efficiency, the environment and health evident in the design, structure, materials and technologies showcased in the house. Construct Ireland spoke to the house’s architect, John Goulding and Director of Century Homes, Paul MacDonald, who explain not only the technological considerations but the environmental demand for such a project.

John Goulding, the architect on the Eco House, has been actively involved in researching energy efficient design for the past 18 years, working through UCD’s influential Energy Research Group, and has worked on several European Commission funded research and building demonstration projects. He explains to Construct Ireland’s Jeff Colley how the Eco House performs.

As if the implications of the unfolding global financial crisis weren’t bad enough, the Irish economy must also contend with the consequences of a banking system exposed to unprecedented property-related debts. Reflecting on the ongoing crisis, Richard Douthwaite explains why investment in local energy innovation may prove the key to improving Ireland’s economic health

Why Ireland’s failing treatment systems & septic tanks must be tackled

Martin Murray, chairman of the Passive House Association of Ireland and founder of Martin Murray Architects, explains why the world’s leading energy efficiency standard is on the up in Ireland

An experienced timber framer with an eye for detail, Tim O'Donovan set about building a low energy stick-built home in the Cork countryside and achieved a staggering level of airtightness.

The cement industry is well known as being amongst the worst culprits for emitting CO2, a seemingly unavoidable side effect of its production. However, as Peter Seymour, Business Development Manager with Ecocem Ireland Ltd explains, there is a strong, eco-friendly competitive alternative to Portland cement that is being specified in a variety of high profile construction projects in Ireland.

If achieving eco buildings is challenging for new build, it is doubly so for renovation projects. Philip & Delphine Geoghegan of iCon Architecture & Uban Design describe a low impact renovation that balances these apparent tensions with great success.

When residents of Hollywood solemnly and publicly state the need to combat climate change, it is easy to reject as self-righteous, opportunistic bleating. When it’s a resident of Hollywood, County Wicklow, and the environmental statement is in the form of a poroton-block house infused with sustainable features, it provokes an altogether different response, as Lenny Antonelli reveals.

In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible
