Abstract | The house in this case study was upgraded in 2009 as part of the SERVE project. It is situated in Nenagh Town. The house is a 125m2 three story dwelling in a two dwelling building. It is built with reference to the 1997 building regulations, and is typical of many buildings built in Ireland over the last 20 years.
The upgrades include :
heating : boiler, domestic hot water controls, space heating controls, wood burning stove
The energy perfomance went from a C2 to a B2.
To get more information download the case study where the measures are detailed in terms of technologies, prices, energy saved and pay-back.
Lessons learnt | After the upgrade the decrease in energy use was predicted to be 40%, in reality it was 34%, or a 15% comfort factor. I.e. 15% of the predicted savings were invested in increased thermal comfort.
