Design Approaches

Interhabs, a company who build to the highly energy efficient Canadian Super E programme, have recently entered the Irish house building market.
Jeff Colley speaks to Ronan Long , General Manager of Interhabs Ireland, about the reasons why he believes Interhabs will bring energy efficient, comfortable, healthy homes to people across Ireland

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.

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.

Built on stilts, entirely encased in recycled newspaper insulation on all sides, and designed to be easily taken apart so that its constituent elements can be reused once it reaches its end of life, Portlaoise Locomotive Drivers Building could hardly be more green. But it is – it’s a certified passive house. Iarnród Éireann senior architect David Hughes explains how such a sustainable exemplar came to be.

Sustainable building at its best is about much more than just energy and carbon emissions, and involves considering location, form, orientation and the use of healthy, environmentally friendly materials. Mike Haslam of trail-blazing ecological architects Solearth describes a family home which scores highly on every front

Creating the right comfort in buildings for elderly people involves ensuring a warm internal environment, which typically results in high energy consumption. John Hearne visited the new Castle Gardens Retirement Village as it approached completion and found a project that combines complimentary low energy technologies, materials and design to deliver high levels of comfort whilst also keeping running costs, energy consumption and carbon emissions low
