Woodspec -First Timber Specifiers Guide Produced in Ireland

The ESB's Home Insulation Scheme aimed to upgrade the homes of 1,000 pensioners on fuel allowance last year - it ended up reaching almost three times that number, reducing carbon emissions and improving the lives of many. Lenny Antonelli found out more.

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

Lime-hemp is developing as a bio composite construction material with serious ecological and energy advantages. Patrick Daly, lecturer in Environmental Design at DIT Bolton St. asks if this is the environmental material of the future and explores its mainstreaming potential.

While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

Number Two Grand Canal Square office, completed in September 2009 and substantially occupied by law firm Byrne Wallace in August this year, set a landmark in commercial office development by combining world-class design with sustainability - reconciling the architecture of Daniel Libeskind with achieving both a Breeam Excellent rating and an A3 BER certificate. Paul Dunne, sustainability and M&E director for Arup, outlines some of the project’s history and its achievements

Mandatory for virtually all building types since January of this year, Building Energy Ratings have been met with little fanfare. Construct Ireland proposes a cost-free method of levelling the marketplace by ensuring compliance and increasing awareness of the BERs legal status. Jason Walsh explains.

The building is the first all timber office complex in Ireland. It covers almost 2,300m2 of floor space and provides accommodation for almost 100 staff working in a wide range of forestry related disciplines.

The worl­d has learned the hard way that our political leaders lacked the judgement and resolve to identify and address the problems which led to the recession. Richard Douthwaite argues that a similarly flawed judgement is evident in the assumption that the economy will recover, and advises on how to prepare for a future of global economic contraction.

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
