BES exclusively works in the commercial and industrial building market segments. We do not work in residential and do not perform work in new construction. Our work is 100% based on retrofit of the building to improve its performance.

Industry Knowledge

What are the typical paybacks?
Depending on the building type, style, and age, we typically find scope in buildings that keeps the ROI in a 3-7 year range. This also largely depends on geographic location due to weather patterns, temperatures, utility costs, and heating source.
