The short answer to your question is that I don't have a specific envelope of funds that are targeted for greening. I have greening as an objective, and it is built into the building management planning process that I referred to in my opening remarks.
Investment in our real estate and our buildings is, I would say, a many-factored initiative. I must take into account the age of the building, the proposed use of the building, and the tenants and their program requirements. Will they be there for five years or will they be there for seven years?
As I look at the overall investment strategy for the building, I need to take all of those factors into account. If we're looking at a tenant who may have a 20-year requirement in the building, then the return on investment is there for me to invest in a greening initiative and to upgrade the building. Those investments will be made. I think you can see that reflected in some of our numbers. We also use the FBI initiative from NRCan, because the private sector in effect fronts the money for those upgrades.
