Dr. Ciaran Byrne:

Just a quick point on that. In the retrofit programme, we have a fabric-first approach which involves getting the fabric structure of the home correct so that whatever the source of heat, less is being used because the fabric of the home has been improved. When we get to that point, we then move to the use of renewable technologies, including heat pumps and solar. Solar power will provide electricity and hot water but it will do nothing for the heating of the home. Approximately 80% of energy usage in the home is for heating the water and the space. We do not want to conflate the two issues. The SEAI is very keen to ensure that people follow through and focus on the retrofit because while we are in an immediate crisis now, we must also look to 2030 and 2050. We want to make sure that the overarching fabric of people's homes is correct. I will ask my colleague Mr. O'Mahony-----
