    With energy savings, there's intent and then there's plan. Industrial facilities in the United States show a sustained interest in energy management. That's the intent: Reduce overall energy usage or sustain usage but increase the amount produced per kW used.In manufacturing, a plan will only stick if it has both the wisdom of experience guiding the vision and the ROI numbers to back up the effort. But in energy, there just isn't the body of research out there for an industrial plant manager to use to set baselines for what "reasonable" energy usage looks like in a manufacturing facility.

  • Diagnosing mold problems

    One of the possible problems in facilities today is the presence and effects of mold on the indoor environment. Molds are normally present in nature. They reproduce by means of tiny spores that float through the air and are invisible to the naked eye. They can grow on wood, paper, carpet, foods, and insulation - but none of the many types of mold will grow without water or moisture. When excessive moisture accumulates in buildings or on building materials, mold growth will often occur, particularly if the moisture problem remains unaddressed.
