Please take the time to visit a nearly zero energy or low energy building in Wicklow or elsewhere in Ireland from 13th – 15th November 2015 (Friday, Saturday and Sunday) during the NZEB Open Doors Ireland 2015 event.

During this weekend, visitors will have the opportunity to visit some of the best examples of low or nearly zero energy houses and public/ commercial buildings in Ireland.

The NZEB Open Doors Ireland event will overlap with the International Passive House Days and the NZEB organisers are working with the Passive House Association of Ireland to jointly promote both events.

Booking places for the visits will be available on their website Nearly Zero Energy Buildings from mid October 2015.

As NZEB Open Doors is seen as playing an important national role in promoting the NZEB standard in Ireland in a practical and tangible way SEAI will be supporting the 2015 NZEB Open Doors campaign.

Go to Nearly Zero Energy Buildings for details about this wonderful showcase of truly excellent houses.

Direct contact can be availed of by phone: 01 4548300 or email: at info@nzeb-opendoors.ie
