The 3 Counties Energy Agency (3cea) have worked closely with both Carlow & Kilkenny Local Authorities and a number of housing organisations such as Respond, Tinteán & Brothers of Charity. 3cea have worked hard to develop award winning housing retrofit projects which have positively affected over 650 homeowners and tenant’s with improved living conditions and most importantly a reduction in their yearly energy bills (2013-2015).
3cea successfully applied for funding under the Sustainable Energy Authority of Ireland (SEAI) Better Energy Communities (BEC) Scheme, where grant funding of up to 80% was provided for housing retrofits. From 2013 to 2015, over €8.2 million was invested into the housing retrofit projects with over €5.5 million through SEAI funding and an additional €0.98 million from the sale of energy credits to the various energy providers.
From 2013-2015, over 3,600 different energy efficiency measures were completed over 650 different homes. This averages out to 5.5 measures per property, meaning that properties were given a full suite of measures bringing them up to date with the current building standards. Some of the measures and the number of completed properties can be seen below.
