I think currently these systems do cost more to build into a project, but it's a different approach on how to do it.
For example, in Dockside they took what the typical development would cost and they shifted the costs around, because they didn't have to pay the city development cost charges. They didn't have to pay the city for waste disposal and so on. So they shifted these costs around to develop their own systems on site. When you are smart about it and you think about it, then the cost increases are relatively small, and they are being accomplished by doing it differently. If you're trying to do this just the same way you have always done building development, you will not succeed. It's a different way of financing projects, developing projects, integrating systems between buildings and infrastructure, and you have to do that to be successful.
It's the same if you use renewable energy. It's a different type of energy. In just producing it and providing enough of it, you cannot have buildings that use enormous amounts of energy. You need to design in first an energy efficiency that allows you to size the other systems smaller. It's all connected; it all has to be integrated, and then the costs are actually quite manageable. Over the life cycle—and infrastructure systems last hundreds if not thousands of years—the benefits are significant.
