BRENDAN HOWLIN, T.D., Minister for the Environment (1994-1997) reflects on the blueprints, policies, and commitments that emerged from the Rio Earth Summit and looks at how far we have progressed since

Any building, no matter how cold and draughty, no matter how remote, can be improved to world-class energy performance, as an upgraded and extended Donegal cottage dating back to the 1800s proves.

In this special feature, Construct Ireland draws from the views, hopes and concerns of four people ideally poised to comment on the implications this directive will have on how we design, construct, renovate, manage and think about buildings in Ireland.

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.

Hotels typically take a heavy toll on the environment, with large amounts of energy used for heating, hot water, lighting, air conditioning and laundry, and huge amounts of waste being landfilled each year. John Hearne visited the Westport Woods Hotel and discovered a highly successful approach to reducing environmental impact that is also yielding substantial dividends in terms of cost savings and positive publicity

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

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.

As the January 2006 deadline for implementation of the EU Directive on the Energy Performance of Buildings draws ever nearer, the Irish Government has spelt out its plans to delay the across the board introduction of building energy ratings until 2009. But how does this compare to other EU Member States?

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

Much hope has been pinned on the development of new technologies for sinking carbon and generating low impact energy. Richard Douthwaite reveals the major contribution that could be offered by something very old; a soil type that has been in use for 6,000 years.
