Welcome to the archive of Construct Ireland, the award-winning Irish green building magazine which spawned Passive House Plus.
The feature articles in these archives span from 2003 to 2011, including case studies on hundreds of Irish sustainable buildings and dozens of investigative pieces on everything from green design and building methods, to the economic arguments for low energy construction.
While these articles appeared in an Irish publication, the vast majority of the content is relevant to our new audience in the UK and further afield. That said, readers from some regions should take care when reading some of the design advice - lots of south facing glazing in New Zealand may not be the wisest choice, for instance.
Dip in, and enjoy!
When Construct Ireland asked Vivienne Brophy of the UCD Energy Research Group to select projects for this feature she suggested that the second year UCD Architecture students make the selection, using UCD’s sustainable building rating system tool to verify their choice
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.
Adding to the list of developers aiming to deliver energy efficient housing, Cronan Nagle Construction are currently on site with 188 highly insulated, airtight homes in Ennis, co. Clare. The development, which also incorporates heat recovery ventilation and condensing gas boilers is surpassing the thermal requirements of Building Regulations by up to 45%, as John Hearne discovers.
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
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
In the future, the high cost and scarcity of fossil energy may force a shift towards retaining and modernising old buildings, thereby avoiding the use of huge amounts of energy to manufacture building materials. John Hearne visited the Belvedere Orphanage, a group of 19th century dwellings whose low energy refurbishment may offer a template for development in the future, by using wood pellet district heating and a host of energy saving measures whilst nonetheless paying great attention to preserving the buildings’ heritage value.
As our recognition of the problems of dwindling fossil fuel supplies and climate change grows, the need to reduce the energy consumption and carbon emissions of our homes becomes increasingly apparent. Leading energy consultant Patrick Waterfield describes why and how we should switch to zero heating homes.
On 7 June 2011 environment minister Phil Hogan TD signed the latest changes to Part L of the building regulations into law, which will make it mandatory for all new homes to be 60% more energy efficient than the standards at the peak of the construction boom. Jeff Colley sheds some light on the key changes
In terms of 1972 money, oil prices averaged about six dollars a barrel between 1987 and 2000. Last October they reached $40. They are now around $50 a barrel which means that they are beginning to climb back into the territory which caused the global economy to crash in 1979/80.
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.
