No matter how energy efficient a building method is, constructing a house from scratch will always cause some damage to the environment - but what if a building material could absorb more carbon than it causes to be released over its life cycle?

At the start of July a key event in the Irish construction industry passed almost entirely unnoticed, with the requirement that the brand new Dwelling Energy Assessment Procedure (DEAP) calculation software be used for all planning applications for new homes with immediate effect. The new tool will be used to calculate Building Energy Ratings (BER) under the requirements of the Energy Performance of Buildings Directive (EPBD). Patrick Daly, lecturer in Environmental Design in the School of Architecture at DIT Bolton St. reveals his view on DEAP and its impact on the industry.

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.

As long term readers of Construct Ireland will recall, the mainstreaming in recent years of sustainable design and construction has been exemplified in many innovative local authority offices. John Hearne visited Aras Contae an Chláir, and discovered a building which attempts to holistically minimise environmental impact, with attention paid to more than just energy performance and carbon emissions.

A new house in west Cork offers a green vision for the future of Irish home building: not only is it A-rated, airtight and highly energy efficient, it’s built with ecological materials that are manufactured in Ireland too.

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

In an ideal world every occupied building in Ireland would be energy upgraded to the highest standard, tapping into numerous benefits for the building occupant, the construction industry and society as a whole. Construct Ireland is calling for the introduction of pay as you save, a repayment model which offers the potential of making significant energy upgrade investments achievable in the vast majority of Irish buildings, as Jeff Colley reveals.

Jason Walsh visited the Green Building, a pioneering sustainable development built in Dublin's Temple Bar in 1994, to find out how one of Ireland’s most ground breaking eco designs has been performing over the last decade.

There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.
