Building Teams need to help owners avoid 'operational stray'

摘要

That help comes in the form of a report from the Natural Resources Defense Council. In "Real-time Energy Management," NRDC's Philip Henderson and Meg Waltner document the results of an eye-opening experiment. Last year, NRDC convinced the Tower Companies real estate firm to have a couple of MEP consulting firms install energy meters and monitoring/ alarm systems on the chillers and HVAC systems of three of its large office buildings in Washington, D.C. This setup gave Tower's facilities staff realtime management of the buildings' energy use over a one-year period. The system enabled the building engineers to find problems they might never have discovered. In one building, faulty VAV controls were telling the chiller to turn on even though the building management system was signaling it to stay off. Early detection saved a lot of energy.
