Lime-hemp is developing as a bio composite construction material with serious ecological and energy advantages. Patrick Daly, lecturer in Environmental Design at DIT Bolton St. asks if this is the environmental material of the future and explores its mainstreaming potential.

The winner of the sustainability award at the 2011 Irish Architecture awards, Roebuck Castle student residence at UCD’s Belfield campus is also the biggest certified passive house project built to date in Ireland and the UK. Tony Rigg of Kavanagh Tuite Architects explains how such a significant building achieved passive results.

Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it. Leading energy consultant Ciaran King of Emerald Energy explains how this occurs, and by describing an assessment of the topic, provides some rules of thumb regarding when thermal mass may be beneficial, and when it may be detrimental.

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.

Up till now, the activities of semi-state energy companies like Bord na Móna, ESB & Bord Gais have not won the favour of environmentalists. Richard Douthwaite explains how that situation is destined to rapidly change, and exclusively reveals details of the ambitious new green direction being adopted by Bord na Móna.

Upgrading and extending a semi-detached house on a tight site in Limerick required ingenuity from architect Patti O’Neill.

Much of the housing built around Dublin over the last forty years has been built of single-leaf nine-inch hollow block construction – which are both notoriously energy inefficient and extremely difficult to insulate effectively without causing damp problems. Lenny Antonelli visited a hollow block house which has been ecologically renovated to protect occupant health whilst shooting to the top of the energy rating scale.

In the first installment of a new feature on international green buildings, Lenny Antonelli takes a look at five innovative, sustainable and striking buildings from around the world.

In the aftermath of our recent awareness raising, Construct Ireland began to research what measures the Irish government was taking to prepare for the Energy directive, and how this compared with views from other EU member states, an investigation that is revealing startling results. Jeff Colley reports.

As Ireland struggles to meet its commitments to reducing CO2 emissions in accordance with the Kyoto Protocol, the renewable energy sector continues to flourish as wind farms rapidly develop and solar energy becomes increasingly viable
