SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

The Dwelling Energy Assessment Procedure (DEAP) is now the national methodology for creation of Building Energy Rating (BER) Certificates for new dwellings in Ireland, and is an important desk top tool for predicting the performance of projects at outline design stage.

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.

 
A framework for strategic sustainability is essential if we’re serious about greening the Irish built environment.
According to green architect Pat Barry, we should look no further than The Natural Step.

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,

Ambitious companies in the Irish sustainable building sector should look to the US, says Century Homes founder Gerry McCaughey. As chief executive of LA-based green building business consultancy Infineco, McCaughey is witnessing first-hand how the land of opportunity is waking up to green construction.

Little did we know when campaigning for the Fingal energy standard in 2005-06 that Construct Ireland would have a direct impact on Ikea’s first Irish store. Driven by a combination of Fingal’s requirements and their own renewable energy policy, the Swedish retail giant has invested in the largest ground source heat pump installation in Ireland and the UK, along with a well-thought biomass system fed by an onsite waste stream and a host of other green measures, as John Hearne reports

While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

Designing a low energy building when you've got unlimited space is one thing – but what if you need to make your walls thin to maximise space on a small site in an architectural conservation area? Lenny Antonelli visited a new St Vincent De Paul sheltered housing project that fit a lot of sustainable features on to a small plot in Dublin's north inner city.
