Explain the difference to me. From what I understand about the Built Green Alberta program, contractors can get a certain number of points for every type of option they include, if they have renewable siding or siding that's going to last a lot longer, so they are not filling landfills, or if they have water- or energy-efficient appliances or better insulation, insulated block basements and those types of things. Once the project is done, you would then rate the building to see if it's energy efficient or not and if it's a pass or fail scenario.
