Already people are watching more streaming media than ever before, youtube, netflix, the list goes on. There are numerous other benefits, such as various businesses able to work more quickly and in conjunction with one another. Sending data, like video from various surveillance cameras. Various Entertainment companies sending massive amounts of data such as movies that are being worked on between several companies back and forth to facilitate and streamline the editing process etc.
A lot more people would start to store their data in the "cloud" since a faster internet would enable them to stream their stored media etc in a central and mostly safe location. The demand for that service which has already started to become a big thing would become an amazing and competitive business, it would grow so much faster. Other companies could also deposit other things into your cloud storage, like say if you gave them family videos to convert etc. They could as soon as the process was done send you it in digital format if that's what you wanted.
There are also numerous other reasons such as Telemedicine, Distance Learning and so many other things. A better and faster internet is good for everyone businesses and private users. How many people who also don't have access to high speed internet would potentially buy services from these US businesses which would in turn make more jobs.
The EPA has various funding options I believe for Green Buildings and some places may well offer Tax break incentives to go green. In the long run a well designed Green building pays for itself. It is also a good idea to have good Natural lighting if you can manage it, the Heifer International building is beautifully designed with this in mind.
Another thing to consider is indoor air quality, I remember there was a TED Talk by Kamal Meattle: How to grow fresh air depending where your building is built and the air quality this can be amazingly good for everyone in the office.
I hope you find this useful even if it wasn't exactly what you were seeking.
