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

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.

With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.

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.

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 proposes a new bank-free, debt-free way of financing property purchase and development to get the market working again and clear up the mess left by the bubble.

The winner of the sustainability award at the 2011 Irish Architecture awards, Roebuck Castle student residence at UCD’s Belfield campus is also the biggest certified passive house project built to date in Ireland and the UK. Tony Rigg of Kavanagh Tuite Architects explains how such a significant building achieved passive results.

In the first installment of a new feature on international green buildings, Lenny Antonelli takes a look at five innovative, sustainable and striking buildings from around the world.

The building is the first all timber office complex in Ireland. It covers almost 2,300m2 of floor space and provides accommodation for almost 100 staff working in a wide range of forestry related disciplines.
