Ireland — along with much of the western world — relies on the International Energy Agency‘s oil production forecasts. But are they reliable, asks Lenny Antonelli?

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

In the third installment of a new feature on international green buildings, Lenny Antonelli takes a look at more innovative, sustainable and striking buildings from around the world.

Planning ahead for Ireland’s electricity supply is by no means a simple matter, given the range of unprecedented issues that are coming to the fore.  Massive cuts in emissions must be achieved, whilst decisive action is required to ensure adequate supply of electricity at a time when usage is spiraling. Richard Douthwaite explains the balance that Ireland must achieve between efficient local generation and usage and ensuring optimal interconnection to global renewable electricity supply

It’s not surprising that a 1970s bungalow on an exposed north-facing site might be draughty and burdened with high energy bills - but external insulation, a new heating system and a brand new roof can make all the difference. Lenny Antonelli reports.

Closed-panel timber frame home in Wicklow with impressive thermal performance and airtightness

Beauty is only skin deep, or so goes the cliché, but is there more to 'grace' in a building than its exterior? Jason Walsh visited Rathnew, County Wicklow, to see how an ordinary office building was being transformed into a paragon of sustainability and spoke to two of the building's designers and occupants, architect Tomás Ó Leary and engineer Mark O'Brien

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

The Transition Towns movement has recently come to the fore as a model for sustainable development, with communities around the world signing up to reduce carbon emissions and build resilience in a world where climate change and energy security are emerging as real threats. Leading eco designer Joseph Little of Joseph Little Architects describes how the recent refurbishment and extension of a Dublin house addresses many of the movement’s concerns.
