Some estimates suggest energy management and maintenance programs can reduce energy use in individual buildings as much as 40%. In fact, the U.S. Department of Energy (DOE) publishes a rule of thumb that operation and maintenance (O&M) programs targeting energy efficiency can save 5%–20% on energy bills with little capital investment at all.

Improving energy efficiency is the first and most important step toward achieving sustainability in buildings and organizations. Energy efficiency helps control rising energy costs, reduces environmental footprints, and increases the value and competitiveness of buildings.


At every level and with every CET service we're driven to save energy, increase comfort, and reduce your carbon footprint.
