On Tuesday the 15th of March a passive house, a house that does not need to be heated, was built a few miles outside of Galway. The brain child of Lars Pettersson of Galway based Scandinavian Homes Ltd, it is believed to be the world’s first standardized and factory made passive house.

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.

Kevin O’Flaherty’s development overlooking Galway Bay combines impressive energy saving techniques with the sorts of features that buyers of high-spec homes have grown to expect, as John Hearne discovers.

Brian Dowd, ESB’s products and services manager, talks about the company’s new energy strategy and the launch of the next phase of their Halo programme.

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.

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects

As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

In the fourth part of a series of articles on the condensation risks associated with insulating single lead dwellings, Joseph Little of Joseph Little Architects & Building Life Consultancy reveals serious problems with the approach taken by regulators, standards authorities and suppliers on the condensation risks associated with insulating single leaf walls.
