It is not sufficient to design a green building without considering its regional environmental impact. If the residents of a green building consume food and other products that have to be transported at long distances at high energy costs, then is a green building truly green. To address this problem, a greater emphasis needs to be placed on purchasing locally grown, sustainable products. One such way to do so is to support hydroponic farms and other suburban fringe sources of agricultural products. Not only does this reduce energy costs associated with transportation, but purchasing sustainable local products is also good for the local economy.
