An energy conscious renovation and extension in south Dublin breathes new life into a typical semi detached home — the house is now wrapped with external insulation and boasts breathable and ecological materials too.

Air-tightness is a key factor in any low energy build, but is often overlooked in comparison to energy sources and insulation. Lenny Antonelli examines how air-tightness is achieved in buildings, from design stage down to the final sealing

The vast majority of Irish buildings are in need of substantial energy upgrade work. Given the difficult economic conditions and low public awareness of the cost, comfort and health benefits of a well-designed energy renovation, the notion of upgrading most Irish buildings is a considerable challenge. However, as Lenny Antonelli explains, new ideas are emerging that could stimulate energy upgrade work on an unprecedented scale.

When it comes to redeveloping old buildings, green designers face two choices: replace existing structures with modern, energy efficient buildings or refurbish and avoid the embodied energy and waste of demolition and new construction. Lenny Antonelli visited a redeveloped convent in Booterstown, County Dublin that combines the best of both approaches.

The mainstreaming of sustainable building technologies is manifesting itself in a growing number of developers seeking to find the greener option. Jason Walsh describes a recent project where airtight timber frame construction meets high-tech solar thermal in a North Dublin House of Tomorrow funded scheme which is delivering low carbon results

Imaginosity, the new children's museum building in Sandyford's Beacon South Quarter development, is getting the Austrian eco-house treatment, combining low energy, modular construction with a plethora of low carbon energy technologies. Jason Walsh visited the site to take a look.

Buildings that are designed or refurbished to use little energy all too often fail to deliver the expected performance, if the building occupants aren’t able to use the building as intended. John Hearne reveals the crucial role that user-friendly heating controls play in ensuring that a theoretically low energy building delivers the expected results.

Building a visitor centre at such an evocative site as the Cliffs of Moher, one of Ireland’s greatest tourist attractions must have been something of a challenge. By attempting to cater for visitors, the centre could so easily have ruined the rugged, barren landscape which makes people visit in the first place. John Hearne visited the new interpretive centre to discover a building which addresses this problem by becoming part of the landscape, whilst using eco technologies to reduce the building’s strain on the broader environment.

An experienced timber framer with an eye for detail, Tim O'Donovan set about building a low energy stick-built home in the Cork countryside and achieved a staggering level of airtightness.
