This is talking about BAS - Building Automated Systems

I took a snippet from the website for you to read - we could use this info and amend it for our argument of the importance and value of our idea.

"One significant benefit from advances in monitoring and diagnostic technology is a reduction in whole-building energy use. Demonstration programs established in a range of commercial and institutional facilities have shown an average reduction in overall energy use of 15 percent. Assuming an annual energy cost of 30 cents per square foot, this translates into a savings of $150,000 per year for a typical 500,000-square-foot facility.

And that is just the average savings. Some facilities have reduced energy use as much as 40 percent. The typical energy payback for monitoring and diagnostic systems ranges from six months to two years."
