3cea Pilot State of the Art Energy Efficient Homes in Carlow & Kilkenny

Construction has begun 8 new energy efficient homes in Carlow & Kilkenny that are part of a NWE Interreg Housing 4.0 Energy (H4.0E) an EU project to lower embodied emissions in house builds and in time reduce the cost of construction by utilising a Design for Manufacture and Assembly (DfMA) model and ensuring the houses are built to nZEB (near Zero Energy Building) standard by using prefabricated timber-frame closed panels or low-carbon GGBS cement composites and energy-saving efforts like installation of Photovoltaic cables and heat pumps. The 2 bedroom and single bedroom houses are located in St Mary’s court in Carlow town, in Mullinivat and Graiguenamanagh (at the old Fire Station)  in Co. Kilkenny.

“3cea were delighted to lead this initiative and to secure Irish funding of over 600K from a Europe-wide fund of 4.2 million made available by the European Regional Development Fund through the Interred NorthWest Europe scheme to make this pilot project happen,” said Communications Officer Colin Healy. “H4.0E-nZEBs or ZEB builds are a must for future construction to meet both Ireland’s housing needs and carbon mitigation goals. The Irish H4.0E pilots are not using full DfMA methods in the pilot project, but when they come fully on stream through the availability of the H4.0E Platform being developed by Open Systems Lab (OSL) as part of the H4.0E project we anticipate that building costs will be reduced by 25% using these methods. The H4.0E houses in the upscaling process will be far cheaper to run and substantial carbon emission reductions will be achieved both in embodied and operational carbon. Heating and domestic hot water are where most of the energy will be used and these are warmer better-insulated homes. All houses are fitted with heat pumps.

 

The houses, referred to as H4.0E houses are part of a plan to develop affordable zero-energy houses by applying new technology to building and running the houses. A carbon reduction of at least 50% to 80%, when compared to a standard concrete/brick build house,  will be achieved. All units will be completed towards the end of this year and will be used for social housing by Carlow and Kilkenny County Councils.
