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.

Ever since the seminal Agenda 21 was endorsed by 150 nations including Ireland in 1992, increasing lip service has been paid to sustainable development in everything from government policy to manufacturers’ claims. However, as John Hearne describes, in Tralee Town Council’s Rath Oraigh housing development, local action has been taken with not only local, but global benefits that embody the principles of sustainable development.

Germany has a reputation for high quality craftsmanship, an attention to detail and a positive attitude to sustainable and healthy housing. Jason Walsh visited a new German-built house in County Dublin to see if the expertise can be exported.

In terms of 1972 money, oil prices averaged about six dollars a barrel between 1987 and 2000. Last October they reached $40. They are now around $50 a barrel which means that they are beginning to climb back into the territory which caused the global economy to crash in 1979/80.

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.

Achieving building regulations compliance and a good energy rating is one thing. Delivering a genuinely low energy building is quite another. A new scheme by one of Ireland’s most decorated developers may help show the market a way forward.

Local authorities upgraded hundreds of houses last year under a €20m government scheme, and the Department of Environment has doubled funding for 2010. With local energy agencies playing a key role on the ground, the programme offers vital lessons for keeping quality high in energy retrofit schemes. Words: Lenny Antonelli
