  • Efficient aeration system boosts energy savings

    A new efficient aeration system saves the Ontario, Ore., wastewater treatment facility $47,000 annually in energy costs. Besides giving this community a financial boost, the new system netted additional equipment cost savings by cutting aeration horsepower by more than half at the plant. The environmentally conscious city, located in the Oregon/Idaho border area, is meeting all of its effluent ...

  • Smart operation of air-conditioning (A/C) and lighting systems for national load management

    In the countries of Arabian Peninsula, demand for electric power, primarily controlled by the air-conditioning (A/C) and generally peaking at 15:00 h, is currently growing well over 5% annually. Adaptations of smart operation of A/C and lighting systems in government and institutional buildings that commonly function between 07:00 h and 14:00 h has been evaluated as a technique for national load ...

  • From air conditioning to urban planning, defaults and standards create dysfunction by design

    How can we stop outdated assumptions from forcing us to waste? Personal heaters are a summer survival tool for many office workers chilled to the bone by hyperactive ventilation systems — an act of self-defense against an epidemic of overcooling that is wasting energy and confounding comfort in not only offices but also large shops, schools and other buildings. An audit ...

  • Saving waste in the boiler house

    Burner technology has improved greatly in recent years. Older Burners had a series of cams and levers that were calibrated to provide specific amounts of air for a particular rate of firing. Being mechanical items, these wore and sometimes required calibration. They, therefore, had to be regularly serviced and calibrated. Generally, new burners use frequency controlled motors and cams to open air ...
