Mr. Phelim Devine:

We had originally built into the design a combined heat and power plant, which is gas fired. That may change because that was the most sustainable technology at the time. Now, that will probably evolve differently. We have built in 1,000 sq. m of grey space in the basement to allow for any emerging technologies that may come to the fore. Hospitals use a lot of energy in terms of heat; it is all medium-grade heat. The heat-pump technology that is now used in houses is getting better and better. At some stage in the future, there may be the possibility of retrofitting heat-pump technology into that 1,000 sq. m to help with reducing energy costs. The systems we have put in place, in terms of the thermal insulation of the facade, the building systems, and natural ventilation where permitted, all reduce the energy footprint of the hospital quite significantly compared with existing facilities.
