Thanks Betty and Colin... good reading... latitudes and platitudes... However, I'm wondering what actions the designers and project mgrs. really plan to take, given budget reality, on this particular project. Photovoltaic and greywater recycling in other projects is great, but I'm anxious to hear what IS being done here.
