Hugh Dorrian, member of the Main Committee of the recently launched Building Limes Forum Ireland reveals lime is regaining ground as a key material not only in conservation projects, but in new build.

The cement industry is well known as being amongst the worst culprits for emitting CO2, a seemingly unavoidable side effect of its production. However, as Peter Seymour, Business Development Manager with Ecocem Ireland Ltd explains, there is a strong, eco-friendly competitive alternative to Portland cement that is being specified in a variety of high profile construction projects in Ireland.

In light of the current economic conditions, an increasing number of Irish people are turning away from buying new homes, instead deciding to make the most of what they’ve got by extending and refurbishing. Lenny Antonelli visited one such house nearing completion in Glasnevin that uses a combination of materials and techniques to aim for highly sustainable results.

Commercial, industrial and institutional buildings use a great deal of energy to ensure the comfort of the occupants and the efficient operation of their businesses. Building Energy Management Systems (BEMS) enable building owners to use this energy efficiently, as Sustainable Energy Ireland’s Chris Hughes explains

Due to the ill-considered productivity of the house building industry towards the tail end of the economic boom, Ireland is now saddled with hundreds of thousands of vacant homes in various states of completion. Structural engineer Sadhbh Ní Hógáin, currently writing her thesis for a masters architectural degree in advanced environmental and energy studies at the Centre for Alternative Technology, looks at the options Ireland has to address the problem.

It is not alone as an artist and historical author of distinction that Peter Pearson is noted.  His role as a conservationist in the last three decades has had a tangible effect in protecting Ireland’s built heritage, and raising consciousness of the value and importance of conservation work

In issue 2 we reported on an innovative new energy bike scheme being implemented in Sligo. Its instigator, Wilhelm Bodewigs, got in touch to tell us about an interesting Tram system proposal for the county

Economic analysts are starting to warn of the threat rising oil prices pose to Ireland’s recovery prospects. Richard Douthwaite argues that energy efficiency and renewables investments must be central to government plans, and explains how more than 100% of the cost of energy investments may come back to the exchequer.

Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

Built in 2004, Tomás O’Leary's house in Wicklow was the first in the country to be certified by the Passive House Institute — but how would it fare when subjected to a BER assessment six years later?
