Below is a comprehensive list of the points that we might be awarded if the project were submitted for accreditation. We are not committing to inclusion of all points in the project; however, we are very much committed to providing as energy efficient and environmentally sensitive building as we can within the total scope and budget of the project. Sustainable Sites SS Credit 1: Site Selection 1 Point Intent Avoid development of inappropriate sites and reduce the environmental impact from the location of a building on a site.
