There are a couple of ways in which the buildings are upgraded. One is through the program that my colleague from Natural Resources described, the federal buildings initiative, where the company would come in and do the work and that work would be paid for through the savings.
For the other, in a department like Public Works, money is set aside—approximately $20 million this year—to specifically undertake these green initiatives. But at the same time, we do work.... For example, there's a building here in Ottawa that we are fitting up for tenants. We are making use of the cabinetry, the furniture, and everything that is still there. We're refurbishing it, which in itself is a green activity to undertake, but it doesn't really get captured in the dollar figures that we've put in the ledger. There are HVAC systems being upgraded all the time, etc., to improve their efficiency. These also contribute to the greening of the building.
