A new timber frame house in the Wicklow hills is arguably the most airtight building ever built in Ireland, boasting wood fibre external insulation and an obsessive attention to sealing

The ESB's Home Insulation Scheme aimed to upgrade the homes of 1,000 pensioners on fuel allowance last year - it ended up reaching almost three times that number, reducing carbon emissions and improving the lives of many. Lenny Antonelli found out more.

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.

At the start of July a key event in the Irish construction industry passed almost entirely unnoticed, with the requirement that the brand new Dwelling Energy Assessment Procedure (DEAP) calculation software be used for all planning applications for new homes with immediate effect. The new tool will be used to calculate Building Energy Ratings (BER) under the requirements of the Energy Performance of Buildings Directive (EPBD). Patrick Daly, lecturer in Environmental Design in the School of Architecture at DIT Bolton St. reveals his view on DEAP and its impact on the industry.

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.

Independent integrated sustainable design consultant Xavier Dubuisson explains why heed must be paid to a recent study on the threats that misjudged energy upgrade work can pose to indoor air quality.

Duncan Stewart demands an energy revolution

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.
