Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.

After a long struggle to build their home, Karen and Steve Ward finally got their wish — an energy efficient, timber frame house that boasts a palette of healthy and ecological materials and a fully renewable heating system.

Buildings that are designed or refurbished to use little energy all too often fail to deliver the expected performance, if the building occupants aren’t able to use the building as intended. John Hearne reveals the crucial role that user-friendly heating controls play in ensuring that a theoretically low energy building delivers the expected results.

Lenny Antonelli visited a recently refurbished complex of social housing flats in Galway city that has combined excellence in urban regeneration with energy efficiency and major strides towards sustainability

Patrick Daly, co-founder of the RiSE (Research in Sustainable Environments) research unit in the DIT has undertaken an in depth study and critique of the current Irish Part L for energy efficiency in dwellings, comparing it in detail to the UK equivalent. The findings raise challenging questions about the Irish standards and methodology and highlight serious shortcomings in comparison to our UK neighbours, permitting substantially higher levels of CO2 emissions from new homes in Ireland than in the UK.

 
A framework for strategic sustainability is essential if we’re serious about greening the Irish built environment.
According to green architect Pat Barry, we should look no further than The Natural Step.

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.

As the en masse energy upgrading of Irish homes and other buildings takes-off on an unprecedented scale, there are real dangers that even conscientious clients, professionals and contractors will make decisions that fail to save energy and create unhealthy buildings. Pioneering green architect Joseph Little, draws from the research and experience of his architectural practice & Building Life Consultancy to offer advice that should be heeded before any energy upgrade.

Intended as a landmark not only architecturally, Áras Chill Dara sets an example for large scale sustainable building, as Construct Ireland’s Jason Walsh found out.

With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.
