Energy management systems: How they work and why they save money

Energy management in large buildings and facilities has become a major issue due to the fluctuations of energy supply and demand. Saving energy, in particular electricity, while maintaining an adequate level of comfort for building occupants is a major consideration for those with responsibility for commercial facilities -- including financial, operational and engineering personnel. This session first reviews the types of systems that have developed in this space and how they compare, feature by feature. Then, to simplify this landscape from an energy users perspective, an "energy readieness" classification is presented that allows energy users to pick a path and a set of systems that is most approriate for their individual situation.
