Ms Clare McGrath:

At an expenditure level on the State portfolio side, we have targeted reducing the rent roll by certain percentages year on year since 2008. We have adopted an international standard for developing key performance indicators, KPIs, on accommodation. This means that we must survey, gather data and measure. The KPIs are cost per square metre, space or personal utilisation and energy costs. While we have information on two of those KPIs and benchmarked them internationally, we have not done so as regards space utilisation. These are the performance indicators on which we and other occupiers of the State's estate are measured.
