Some buildings, by their nature, tend to have larger energy requirements. Occupied around the clock, with occupants who feel the cold, nursing homes are a case in point. John Hearne visited a north Dublin building where a range of different sustainable technologies operate in tandem to deliver the residents’ heating and hot water requirements

Imagine moving into a house without a heating system – what would you do? Contact the developer and demand they put one in immediately? Call a solicitor and sue the builder? Or sit back and enjoy living in a house, designed to meet your expectations of comfort without any recourse to a space heating system. Jason Walsh met the people behind Ireland’s drive toward the passive house.

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.

Do termites apply building science better than humans? Award winning architect Sean Harrington takes a characteristically left-of-brain approach to our international feature, leading to some humbling lessons.

If you are at all worried about keeping construction costs down and lengthening the useable lifespan of your building, it’s critical that energy performance is considered from the earliest stages of planning and design. John Hearne spoke to a number of leading Irish experts in sustainable design about following simple principles of orientation, form and layout to achieve substantial energy improvements for free

With the goal of achieving zero carbon standards for new homes by as soon as 2013, environment minister John Gormley has committed to introducing 60 per cent energy and carbon reductions under changes to part L of the building regulations next year. John Hearne spoke to leading industry figures to find out how the revised regulation could raise standards for both new and existing homes.

It’s not often you find an industrial facility that combines low carbon construction with emphasis on natural materials, occupant health and energy efficiency, but Rehan Electronics’ new Wicklow factory is no ordinary building. Lenny Antonelli paid a visit to what must be Ireland’s greenest factory.

U-value alone is a blunt instrument for gauging the thermal performance of a building. Ground-breaking eco architects Joseph Little and Benat Arregi of Building Life Consultancy explain why our increasingly ambitious insulation efforts must involve a rigorous attention to thermal bridging if we’re serious about creating low energy, healthy buildings.

If achieving eco buildings is challenging for new build, it is doubly so for renovation projects. Philip & Delphine Geoghegan of iCon Architecture & Uban Design describe a low impact renovation that balances these apparent tensions with great success.
