I thank the witnesses. I can bring Deputy Ó Broin back in again, but I will now ask some questions. At the outset, Senator Fitzpatrick asked about the cost of construction and if there are different methods of construction that would bring down the overall costs. There is more to costs than just the finance, as we are talking about carbon cost. Can we compare timber-framed construction to the traditional, conventional concrete-block construction we see most of the time? I am talking about house construction and off-site prefabrication. Is it possible to compare the three costs and to say that one is substantially cheaper to do than the other? I will direct the question to the Irish Green Building Council but I do not mind whoever responds if they have an answer to the question.
