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.

An ambitious new community initiative aims to run Clonakilty on 100% renewable energy — and with similar projects sprouting up across Ireland and Europe, it offers one local example of how our Energise Ireland campaign can achieve its primary goal: weaning Ireland off fossil fuels and on to green energy.

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.

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.

Completed in December 2009, Graham Group’s new headquarters reveal the construction and asset management company’s commitment to green building. The project’s sustainability adviser, Chris Croly of BDP describes an innovative design that pushes the boundaries of natural ventilation and takes a thoughtful approach to materials and buildings services to ensure a minimal environmental impact.

With the threats posed by anthropogenic climate change now accepted as a key international issue, efforts to curb carbon dioxide emissions are becoming manifest around the world in spite of – and even as a response to – the global recession. But any such efforts may be in vain if the focus on carbon dioxide distracts from the need to curtail methane emissions, as Richard Douthwaite explains
