I am the green committee team leader for my company location in Chicago. Our team has focused on all the standard green issues of reduce, reuse & recycle. Approximately 85% of our waste is recycled.
We have been looking at planting trees on the south side of our un-air conditioned building. This is to add to the environment and also reduce the solar heat during summer and reduce the amount of wind hitting the building during winter. We have only been able to install 3 evergreens so far. Does anyone have an suggestions on where to get trees for a good price? we are looking for fast growing and providinig a lot of shade.
