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 oil prices remaining at ominously high levels in spite of sluggish economic growth figures and efforts by the International Energy Agency to release additional capacity, Ireland must act fast to cut oil usage. Why then, has the government withdrawn grants for renewables while continuing to subsidise oil and gas boilers?

Nothing focuses the mind like a target. The growing impact of Building Energy Ratings (BER) is increasingly encouraging Irish people to aim for the highest energy rating they can. Patrick and Niamh Daly’s house in Mullingar takes this trend to the next level, using a myriad of sustainable green materials and technologies to become a net energy producer and go beyond the limit of the BER scale. John Hearne visited the nearly completed house to find out more.

Box-like, small windows, primary colour renders - there is a common misconception that building to the passive house standard involves sacrificing design freedom for the sake of thermal performance. Not so, argues passive house guru Tomás O’Leary of MosArt and the Irish Passive House Academy, as his selection of architecturally diverse buildings reveals.

Although not a particularly sustainable building in many regards, there is much environmental merit in the Dominic Stevens designed Mimetic House, a 1300 Sq. ft structure built for e120,000  near Dromahair, Co. Leitrim. The house’s builder Conor McManus of GreenTek Construction, specialists in building highly ecological, low energy, airtight homes and extensions, describes the sustainable aspects of the house.

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

Earlier this summer SEI announced that, from December, external wall insulation systems must have Irish Agrément certification to be eligible for support under the Home Energy Saving scheme. But many in the green building sector are critical of the decision, and some are questioning the value and purpose of Agrément. Lenny Antonelli reports.

Planning ahead for Ireland’s electricity supply is by no means a simple matter, given the range of unprecedented issues that are coming to the fore.  Massive cuts in emissions must be achieved, whilst decisive action is required to ensure adequate supply of electricity at a time when usage is spiraling. Richard Douthwaite explains the balance that Ireland must achieve between efficient local generation and usage and ensuring optimal interconnection to global renewable electricity supply

Ill-considered attempts to upgrade a building’s thermal performance can not only fail to save energy, but can also create serious problems for occupant health and building structure alike.
