Lime-hemp is developing as a bio composite construction material with serious ecological and energy advantages. Patrick Daly, lecturer in Environmental Design at DIT Bolton St. asks if this is the environmental material of the future and explores its mainstreaming potential.

 

If you’re applying for planning permission to build in Cappagh, North Ballymun or Northwest Balbriggan, 30% of your heating must come from renewable energy, and your heating must be less than 50Kwh/m2 per annum—roughly twice the standard of most new homes.

Ireland's largest passive house development to date, Shanganagh Castle, is proof that with proper planning and collaboration, delivering high density housing doesn’t mean compromising on quality or climate action – without increasing costs or causing delays.

As energy prices continue to rise, the Irish construction industry is moving into uncharted territory, where all elements that affect energy performance—from orientation, to building design, to specification, to standard of workmanship—are increasingly recognised as key concerns.

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.

With an economy fuelled by a government approach to planning that many people equate to a road building and house building free for all, it should come as no surprise that quality of life suffers

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?

With the threats posed by anthropogenic climate change now accepted as a key international issue, efforts to curb carbon dioxide emissions are becoming manifest around the world in spite of – and even as a response to – the global recession. But any such efforts may be in vain if the focus on carbon dioxide distracts from the need to curtail methane emissions, as Richard Douthwaite explains

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.

The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains
