Foxrock passive development built with externally insulated poroton & aircrete blocks along with timber frame

A new house in west Cork offers a green vision for the future of Irish home building: not only is it A-rated, airtight and highly energy efficient, it’s built with ecological materials that are manufactured in Ireland too.

When it comes to redeveloping old buildings, green designers face two choices: replace existing structures with modern, energy efficient buildings or refurbish and avoid the embodied energy and waste of demolition and new construction. Lenny Antonelli visited a redeveloped convent in Booterstown, County Dublin that combines the best of both approaches.

Ireland's first passive house development emerged as the big winner at the inaugural Isover Energy Efficiency Awards in February. We look at the winner and other finalists

‘‘We have a body of extremely experienced and competent staff who will be able to hit the ground running”

Just outside the quiet rural town of Templepatrick, County Antrim, located ten miles north of Belfast, is a timber frame house that sets new standards for comfort and, the owners hope, sustainability. Jason Walsh visited the house and found a traditional aesthetic that belies its ultra modern sustainability features

The vast majority of Irish buildings are in need of substantial energy upgrade work. Given the difficult economic conditions and low public awareness of the cost, comfort and health benefits of a well-designed energy renovation, the notion of upgrading most Irish buildings is a considerable challenge. However, as Lenny Antonelli explains, new ideas are emerging that could stimulate energy upgrade work on an unprecedented scale.

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.

Patrick Daly  highlights that the energy refurbishment of our existing housing stock must become a priority. Daly has undertaken a retrospective DEAP case study assessment of an example house and its BER ratings, with staggering results.

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.
