  • 56. Conclusion An effective building control system is not a commodity, nor is it a cost. A well engineered and maintained building automation system can provide a return on investment over many years. Ensure that the automation system you install or modify is fully programmable to take advantage of control strategies. Make sure the energy conservation measures you put in place today are sustained over time. The best way to do this is to use energy services from a provider that understands the complete building envelope and the interrelated aspects of the building that affect energy demand. Finally, require your energy services provider reduce your building’s energy cost immediately, provide a sensible return on investment timeframe, and convey confidence that they are proposing products or services that are necessary and effective to achieve your energy savings goal Schneider Electric - BMS BU 8th June 2009 56
