  • Home energy devices: Can we bewilder Edison?

    Why do so many energy insiders insist that home energy automation will fail?  Many whom I respect say the typical householder will never take the time to fiddle with smart gadgets that reduce energy costs. Their skepticism, however, just elicits a verbal shrug from Peter ...

  • Sub-metering of natural gas-flexible flow measurement delivers improved accuracy and substantial savings

    Introduction Unlike oil, natural gas exists in abundance in the United States. Of the natural gas consumed in the United States in 2011,95% was produced domestically. The U.S. Energy Information Administration projects U.S. natural gas production to increase from 23.0 trillion cubic feet in 2011 to 33.1 trillion cubic feet in 2040, a 44% increase. Almost all of this increase in ...

  • Case study - Multi-tenant building energy efficiency

    Buildings accounted for roughly 40% of total U.S. energy consumption in 2010, according to the United States Energy Information Association. “[New York] City's roughly 1 million buildings cost $15 billion a year to power and heat and account for 80% of the city's greenhouse gas emissions”(1). The proliferation of smart energy devices and building management systems will result in the ...

  • Variable frequency drive energy saving on air compressors

    When we are looking for an innovative way to make its rotary-screw compressors more energy efficient and operator-friendly, they turned to Gozuk, Low-Voltage VFDs. In addition to supplying VFDs to control the speed and torque of the AF-series compressors, the Gozuk project team designed software to control the system pressure, air delivery, oil temperature and duty cycle directly from the VFD. ...

  • GEM provides fast payback for Italcables

    Metered tests carried out on Thermal Energy International’s GEM steam traps by Italcables, Italy’s largest producer of wire strands for pre-stressed concrete and post-tensioned structures, have shown steam savings of up to 30% compared to mechanical traps.  Now, Italcables has fitted GEM traps to its steam baths and kettle boiler used for ‘pickling’ and treating iron ...

  • Luminant Oak Grove Power Station - Case Study

    Powering Texas Luminant, a subsidiary of Energy Future Holdings Corp. (EFH) -which owns competitive and regulated energy subsidiaries in Texas -is the largest electricity generator in Texas. Unit two of the Oak Grove Power plant near Franklin in Robertson County, TX went online in the middle of 2010. Fluor, the project’s EPC company, completed the plant in 35 months and used ...

  • CDM monitoring & reporting for carbon credits case study

    Abridged from a Wastecon 2008 Presentation and Paper by Mitchal L. Cassel LANDTEC, Colton, California The project sites The project is in Brazil and obtains certified emission reductions (CER) or carbon credits for a large scale, waste handling and disposal, clean development mechanism (CDM) project. Methane emissions are being reduced through collection and destruction of ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • HVAC Monitoring Saves Costs for a School Building

    Wireless Technology from CAS DataLoggers Monitors Energy Usage in Real-Time This summer, CAS DataLoggers recently supplied the wireless datalogging solution for a middle school maintenance supervisor who needed to perform power factoring on the building’s HVAC system before winter arrived. The school needed a lightweight ...

  • Video Reveals the Truth About Smart Grid

    We don’t think about energy until something goes wrong, and this week things went wrong on an historic level. As a result, the public and pundits are again focusing on the fragility of big electric grids. Ten percent of the world’s population – more than 600 million people – lost their power in India on July 31, marking the largest blackout in history. India’s grid ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

  • The mystery of electronic water treatment unveiled

    The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...

    Keeping your pump in shape will help reduce costs and boost profits! Cut fuel consumption, reduce replacement parts costs and minimize pumping time on every job! A PUMP THAT LETS YOU DOWN when you need it most causes obvious losses of time and money. Not so obvious, but every bit as costly, are losses you can incur with pumps that operate at less-than-peak efficiency. A pump ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...
