I have a couple of questions. This question is for Mr. Barry. No. 2.2 states that, "Renovating and adapting buildings almost always has a lower environmental impact than that of new builds." We had IBEC in here last week and it talked about the cost of the climate change plan and stated that there is an affordability issue with the transition. It said the affordability of the transition work may never have fully surfaced. That is fair enough. Is there a cost issue between a new build versus retrofitting, renovating and adapting? I presume it is probably more expensive to retrofit, purely in monetary terms but I know there are benefits in terms of emissions. What is your view?
