Possibly the most notable part of that definition is the requirement for continuous improvement. Facility managers who choose to go through certification must set and then meet particular targets for improved energy performance. Those energy performance targets must be certified by a third party. Experts suggest six steps to ISO 50001 certification. First, get buy-in from upper managers. Second, collect, track and analyze energy data. Third, identify the exact sources of the building's energy use. Fourth, establish a baseline of energy use. Fifth, identify opportunities for savings. And finally, create a system to prioritize energy-saving strategies.
