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.

As policy makers start to set mandatory low energy and renewable energy requirements as conditions of planning, the ability of the construction industry to find sound low-cost ways of achieving the new standards is becoming a key factor. John Corless speaks to leading sustainable building consultant Jay Stuart of Delap & Waller EcoCo and Paul Gilmartin of Ecobead to discover an approach with enormous potential for en-masse usage.

Built on stilts, entirely encased in recycled newspaper insulation on all sides, and designed to be easily taken apart so that its constituent elements can be reused once it reaches its end of life, Portlaoise Locomotive Drivers Building could hardly be more green. But it is – it’s a certified passive house. Iarnród Éireann senior architect David Hughes explains how such a sustainable exemplar came to be.

As the organisation entrusted by OECD countries to predict future global energy supplies, the International Energy Agency’s projections have significant impact on energy policy around the world. IEA officials recently told The Guardian that the organisation’s figures on oil supply had been inflated and that oil peak is happening. Richard Douthwaite assesses the fall out

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures. 

Atop a hill in New Ross, County Wexford, is a beacon for sustainability in large-scale developments, which draws extensively from across the palette of sustainable building options to achieve a building that is notable not just aesthetically, but also in health, energy and environmental impact terms. Jason Walsh visited the new Solar Croi spa, part of the Brandon House Hotel, Health Club and Spa, to find out more.

As Building Regulations tighten on carbon emissions, energy reduction and mandatory renewable energy targets, the task for designers becomes harder and harder. Bobby Gilbert of Bobby Gilbert and Associates explains how a new design tool is making sustainable design easier.

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.

More and more businesses are looking to alternative energy sources to light, heat and cool their buildings but few have made a commitment to cutting carbon emissions to match Newbridge Silver, a silverware manufacturer in County Kildare. Jason Walsh visited the factory to find out more.

John Hearne spoke to a number of independent energy experts to develop an impartial view of the main sustainable heating options.
