The market for new residential build may have bottomed out, but compared to the rest of the construction industry the sustainable building sector appears buoyant. Changing market conditions, various government incentives and updated building regulations are all helping greener building companies - but with few houses likely to be built this year and capital restricted, challenges still lie ahead.

As Construct Ireland goes to press, the construction industry awaits Ministers Dick Roche and Noel Dempsey to sign off the long overdue timetable for implementing the Energy Performance of Buildings Directive, a piece of legislation set to make energy performance a key factor in property sales. But can Ireland train up enough auditors to label buildings by January 2006?

Few words in the vocabulary of Ireland’s built environment come with more baggage than ‘bungalow’. For many people, it embodies a total disregard for good architecture and the environment, in part due to its association with isolated one-off housing. John Hearne visited a house in Mayo that mixes considered design with a host of modern technologies to breathe new life into the form.

An advocate of sustainable building long before it was fashionable, Bill Quigley of NuTech Renewables has subsequently seen the mainstreaming of sustainability at first hand, having input into substantial projects for Leahy Bros, MKN and GEDA Construction amongst others. In their latest project, NuTech are working with Wicklow County Council on a social housing scheme with impressively high energy performance targets to meet, as Quigley explains.

While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

Atop a hill in New Ross, County Wexford, is a beacon for sustainability in large-scale developments, which draws extensively from across the palette of sustainable building options to achieve a building that is notable not just aesthetically, but also in health, energy and environmental impact terms. Jason Walsh visited the new Solar Croi spa, part of the Brandon House Hotel, Health Club and Spa, to find out more.

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.

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.

The announcement in 2007 of the introduction of Smart electricity metering led to widespread hope that Ireland could set a global example by empowering consumers to cut electricity use and generate their own renewable electricity. John Hearne investigates current progress on the initiative, and discovers signs that Ireland’s approach to smart metering could represent a missed opportunity.
