Hear what Our Customers Say…
“MacDonald-Miller implemented a software platform that allows us to create energy baseline metrics for each of our buildings. This tool gives us a way to measure the energy performance for our entire portfolio in real-time. Energy monitoring is better for building performance, and it’s better for our bottom line. We see cost reduction through energy savings. It saves KCLS money by reducing energy consumption, improving performance, and saving time and resources.” – Greg Smith, King County Library System
