Financing isn't the first thing that comes to mind when you here the term green building. Instead it's usually solar panels, bamboo flooring, or a piece of plumbing equipment you're not sure you really want to understand. But just like other building materials, green products cost money. What makes them different is that green products typically provide a greater return on investment than conventional products.
One example is - yes you guessed it - a plumbing product; the dual-flush toilet.
