With an economy fuelled by a government approach to planning that many people equate to a road building and house building free for all, it should come as no surprise that quality of life suffers

Nowhere demonstrates the need for a high-performance building envelope quite like a coastal site. John Hearne visited a cutting edge timber frame house overlooking Sligo Bay that was designed to achieve a highly insulated, air-tight and low embodied energy envelope whilst making the most of the spectacular vista.

Designing a low-energy public building with passive ventilation and lighting in mind is one thing – making it fit seamlessly into a rural wetland environment is quite another. Lenny Antonelli visited the award-winning Ballybay Wetlands Centre in County Monaghan - a closed-panel timber frame structure designed to sit softly on the surrounding landscape.

There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.

With some of the most impressive moves toward sustainability over the last few years coming in the form of planning requirements, it should come as no surprise that many local authorities are pioneering energy efficient housing in their own housing stock. Jason Walsh visited a site in Oldtown, County Dublin, to see how Fingal County Council is putting sustainability into practice with help from Keenan Timber Frame, Ecological Building Systems, Nutech Renewables and others

Designed and patented by Irish firm NuTech Renewables, solar enhanced ventilation aims to bring big energy and cost savings to the retrofit market by combining solar and ventilation technologies. NuTech’s Bill Quigley explains how it works.

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

‘‘We have a body of extremely experienced and competent staff who will be able to hit the ground running”

Government incentives are crucial to sparking a massive energy upgrade of our housing stock, but practical examples are just as important. Keen to push his home's energy performance to the limits, one Dublin homeowner overhauled his entire building fabric and installed renewable heating systems and heat recovery ventilation. Lenny Antonelli visited the house.
