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.

Bank of America Tower, to be located at One Bryant Park in midtown Manhattan is a US$1 billion project that has been designed to be one of the most highly efficient and ecologically friendly tall buildings in the world. The building, currently under construction, is expected to be complete in 2008.

Jason Walsh got in touch with Cook + Fox Architects in New York, designers of the Bank of America Tower to see how the practice plans to square the circle of designing an environmentally sound high-rise building.

It could be a reflex response to the shockingly poor construction standards that came to define Ireland’s boom years, but the world’s leading low energy building standard is starting to thrive in Ireland. As the several case studies following this article reveal, a groundswell of Irish clients, designers, contractors and manufacturers are starting to recognise the opportunities available in becoming early adopters of a standard destined for exponential global growth.

Randy Ralston and Mel Cronin aimed for the passive house standard with their upgrade, and though they didn’t quite get there they ended up with a house that produces more energy than it consumes, making it one of the country’s flagship green renovation projects.

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?

The rapid emergence of sustainable building in Ireland has been heavily influenced by the techniques of early-adopters extending from Scandinavia, to Canada, to Germany and Austria. John Hearne visited a recently completed timber home in Galway which uses Austrian know-how to couple air-tightness, high levels of insulation and healthy materials with a sustainable approach to heating and ventilation

An increasing number of sustainable homes are being built in Ireland but many of them are in rural areas, and yet, Ireland is an increasingly urban society. Jason Walsh looks at one recent attempt to renovate a small terraced house in inner-city Dublin, bringing it up to modern environmental and energy efficiency standards.

The introduction of smart metering later this year presents a great opportunity to engage Irish people en masse into substantially reducing their energy consumption, simply by showing them how much electricity they’re consuming, and how much the cost varies at different times of the day. However, as Richard Douthwaite warns, there is a real risk that smart metering may come in a form that benefits the electricity companies and not the end-user.

Until recently the York Street flats had been a living legacy of failed past approaches to social housing – a slum of mainly north-facing flats dating from Victorian times, and poorly rebuilt in the year Ireland became a republic, 1949. John Hearne visited the recently redeveloped York Street and found a thoroughly sustainable set of buildings that should inspire thoughts of future progress rather than past failings.
