Éasca's Aims

FC ParkÉasca was formed to promote sustainable building in Ireland and to facilitate positive change in order to mainstream sustainable building practices. 

It brings together the most innovative private companies in the built environment. Member companies are assessed by independent assessors to ensure their products and services have a positive impact on the environment.


Éasca was founded in 2006 by Duncan Stewart, Earth Horizons; Jeff Colley, Construct Ireland; Paul Leech, Gaia Ecotecture; Sally Starbuck, Irish Ecological Design Association, Tom Woolley, Queens University; and Rahim O'Neill, Cultivate.

Éasca owes its initial set-up and continued growth to its support from Construct Ireland Magazine (now Passive House Plus) and Cultivate Living & Learning.

European Projects

aqua conserverÉasca is a consortium partner in the AquaConserver project that was funded by the European Commission as part of the Framework Seven SME scheme.  The AquaConserver concept addresses the twin problems of energy and water conservation faced by all citizens of the EU27 and offers Europe’s leading Plumbing SME Associations an opportunity to bring a new demand-led offering to our customers, requiring high levels of expertise and training to install correctly and efficiently.

Our concept involves the development of a low cost, water recycling system that can be retro-fitted to 90% of domestic dwellings. It is capable of the re-use of showering and bathing water thereby saving up to 50% of personal washing water usage and >50% of the associated heating energy usage AND it is capable of re-using filtered grey water from bathing/showering for toilet flushing thereby saving up to 35% of overall household water usage.

Éasca Charter

By joining Éasca, members are expected to commit, where applicable, to:

  • Build today without compromising the needs of tomorrow
  • Achieve best practice standards in their own field
  • Aspire to provide for products/services/building works to be carbon neutral or zero carbon and zero waste
  • Ensure high levels of energy efficiency are incorporated into all works and in particular: All building, where possible, should follow the principle of low impact and high performance design, improving the efficiency of the whole building and minimising energy loss through high levels of thermal insulation, following bio-climatic principles of solar orientation and compactness in order to gain a useful percentage of passive solar heating contribution, efficient electrical appliances and maximising day lighting and the use of active renewable energy where appropriate.
