How this Waterford home went from a G to an A3 energy rating

This 1940s Co Waterford cottage was upgraded to become a super energy efficient home in 2019. The renovation was such a success it won the Sustainable Tipperary NZEB Design Competition. Here’s how they went from a G to an A3 eneryg rating.

Most people don’t decide to heavily invest in upgrading the energy efficiency of their home unless they have bigger plans, such as, say, adding an extension.  

      Their motivation also tends to be quite clear. They may have just bought a house, wanting to make it comfortable for their family. Or they may want their existing home to be more comfortable and maintenance free. 

      James and Phil Hallinan are a case in point. Nearing retirement, the couple inherited an old cottage which they decided to do up by increasing the floor area. To make the house warm, healthy and efficient to run, they also invested in an energy upgrade.
