Just to come full circle, we would advocate that chillers and heating pieces of equipment be included in class 43.2 of the Income Tax Act. Giving those the 50% depreciation rate that we're talking about here would fall in line with many other pieces of energy efficiency equipment.
From a cost standpoint, it's difficult to project. We are still working with NRCan on the number of buildings across the country that are, let's say, 20 years or older. If we had, say, 800 buildings taking up this program across the country, you would certainly see short-term revenue loss for government in terms of tax income, because you'd have an increased depreciation rate. What we'd see over a 10-year period, we think, would be increased revenue from the amount of jobs and the amount of actual work that's needed to enact these pieces of energy efficiency.
From a greenhouse gas and environment standpoint, we see massive reductions in the use of CO2. Just to put it in perspective, if this went through with 800 buildings and the numbers we're working with right now, we would see the equivalent of 145 Toronto high-rise condominium apartments being taken off-line. That would be the reduction in energy use, from our standpoint, but after 10 years we would see a net positive gain for government in terms of revenue.
