This project consists of near zero energy and low carbon housing units, equipped with PV panels.
About this project
This project consists of near zero energy and low carbon housing units, equipped with PV panels, heat pumps, an increased airtightness and a high insulation in the walls and windows
There are 2 semi-detached, 2-bedroom, bungalow housing with 4 units in Carlow (15 – 18 St. Mary’s Court, Carlow Town, Co. Carlow).
In Kilkenny, there is 1 semi-detached, 2-bedroom, bungalow housing with 2 units in Mullinavat (Buckstown, Inchacarron, Mullinavat, Co. Kilkenny) and 2, 1-bedroom, apartment-sized housing units in Graiguenamanagh (Old Fire Station, High Street, Graiguenamanagh).
All these housing units will belong to the County Councils and be used as social housing. These are NZEB buildings with different pre-BER energy ratings (the objective BER rating of the finished build). These builds have about a 30 – 60% reduction in embodied carbon compared to a standard (standard concrete brick) build. Every unit will also be equipped with 2kW PV panels and run with heat pumps.
There are several benefits associated with a H4.0E house that both feed into their lower carbon nature, and come as a result of. For example, through the use of 2kW PV panels on the roof, each house will have a lower energy consumption, leading to lower energy bills.
The Graiguenamanagh and Carlow units have achieved a pre-BER of A1 (<25 kWh/m2/annum)
Mullinavat has achieved a pre-BER of A3 (<50kWh/m2/y) but still holds an embodied carbon reduction compared to standard builds.
These houses are also warmer thanks to an increased airtightness and a high insulation standard in the walls and windows.
Finally, in the long run (with the help of the platform) these houses are expected to be cheaper to build with a potential saving of 25% compared to standard builds.
