BRENDAN HOWLIN, T.D., Minister for the Environment (1994-1997) reflects on the blueprints, policies, and commitments that emerged from the Rio Earth Summit and looks at how far we have progressed since

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

As fossil fuel prices rise, the need for energy efficiency in achieving both is increasingly leading Irish people to an approach which combines both ventilation and heating,

The advent of central heating improved the comfort of life for countless Irish people over the past century, but as energy efficient building grows, some pioneering homeowners think they can live without it. What’s life like for them?

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

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.

At Tom Heneghan’s new development in Dromard, Belmullet, Co. Mayo, it’s a case of sixteen units down, eleven to go as Construct Ireland goes to press. Exceeding the thermal performance requirements of the Building Regulations by some 60%, these houses incorporate a range of innovative and affordable sustainable building technologies which together deliver high comfort, low energy living, as John Hearne reveals.

Recent allegations that a single leaf timber frame development in Leitrim was forced to incorporate an outer layer of blockwork in spite of no such requirement in the Building Regulations or by the local authority in question suggests that something is seriously amiss, as Frank Coles explains.

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.
