Mr. Phelim Devine:

I do not see the fabric of the building changing in any way because we have already set a very high standard in terms of its design. It is class-leading. Because of the transformation that is under way as regards heating, solar panels, renewable energy and heat pump technology, over the medium term, there may be a change as to how heat is brought into the building. Most of the energy consumption of a hospital relates to the air systems. That is what generates most of the cost and that is not going to change.
