Construct Ireland investigates what measures the Irish government is undertaking to actively encourage the homeowner to switch to non-polluting renewable energy sources.

Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

The environmental impact of the built environment extends far beyond energy consumption and carbon emissions throughout a building’s intended lifespan. Architect and sustainable design consultant Sinéad Cullen of DW EcoCo & BE Architecture explains why there’s a need to design buildings that can be deconstructed rather than destroyed once they reach their end of life, and looks at the obstacles to be overcome to make this happen.

A new development in County Westmeath answers a nagging question about district heating: how to make it financially viable when it services energy efficient buildings.

Mixing excellent thermal performance with renewable heating, efforts to boost biodiversity and plans for micro-generation, a new timber frame house in rural Cork shows that both appealing design and low environmental impact can be achieved with one-off rural housing.

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.
