Case study: Reducing Costs with Cloud-Based Energy Management [Water Recycling Plant]

RCR Wireless News, Nov. 18, 2016, by Phillip Tracy.

"The Monterey Regional Water Pollution Control Agency claims to operate the world’s largest water recycling facility designed for raw food crop irrigation, using 25 pumping stations to treat 20 million gallons of wastewater every day. Pumping, treatment and conveyance are a few of the most expensive and energy exhaustive processes for regional municipalities, comprising more than 30% of their budgets, according to a case study provided by Candi Controls. The MRWPCA chose an energy management and control solution to try to reduce operating costs associated with its operations."

Commissioning Lighting Control Systems

Processing and Packaging: Thermal Processing Equipment Is Saving Energy, Product and Money

Food Engineering, Sept. 2016, by Wayne Labs.
http://www.foodengineeringmag.com/articles/96121-thermal-processing-equipment-is-saving-energy-product-and-money

"The commercially canned products available in the past largely contained overcooked food that was mushy, too salty and tasted anything but fresh—if it had any flavor at all. The only positive characteristic was the safety, with the impossibility of any bacteria surviving the process unless the can was faulty. Thankfully, though the basic procedures are much the same, since then a lot has been discovered about thermal processing—we’ve turned down the heat and maybe even saved a little energy in the process."

School Integrates DDC for VRF to Improve Control, Energy Management

HPAC Engineering, Apr. 2016, by Alerton.
http://hpac.com/building-controls/school-integrates-ddc-vrf-improve-control-energy-management

"When York County School Division renovated Magruder Elementary School in Williamsburg, Va., in 2015, it chose to install variable refrigerant flow (VRF) for heating and cooling. The wall controllers supplied by the VRF manufacturer, however, lacked dual set points, night setback, and consistent interoperability across competing systems, restricting the school division’s ability to manage energy use. For more robust and consistent control, [the VRF was integrated with a communicating sensor-controller combination]."

Sewage Treatment Plant Retrofits Diffusers to Cut Energy Consumption 50%

Blower & Vacuum Best Practices, Apr. 2016, by Doreen Tresca.
http://www.blowervacuumbestpractices.com/industries/wastewater/sewage-treatment-plant-retrofits-diffusers-cut-energy-consumption-50

"In 2012 when the plant was struggling to keep up with regulatory requirements, the Ilmajoki STP [Finland] was using 4000 kWh per day. Once the new diffusers and control systems were implemented, the plant was able to reduce their consumption and averages to under 2000 kWh per day."

Zero Net Energy Building Controls: Characteristics, Energy Impacts and Lessons

Continental Automated Buildings Association (CABA), Nov. 2015, prepared by the New Building Institute.

Air Compressor Control for Industry 4.0

Compressed Air Best Practices, Nov. 2015, by Clinton Shaffer.
http://www.airbestpractices.com/technology/compressor-controls/air-compressor-control-industry-40

"We are in the midst of the fourth industrial revolution, or, as it is known in Germany, Industry 4.0. In broad terms, the concept describes manufacturing facilities where all of the machines — including the air compressors, along with their corresponding sensors and air treatment equipment — communicate with each other autonomously, recording performance metrics to a local controller, a wireless network, and an external database. These communicative abilities are enabled by the Industrial Internet of Things (IIoT), in which intelligent, networked devices link everything back to a main data hub."

Managing Multiple-Compressor Systems: Utilizing Controls to Improve Performance

Compressed Air Best Practices, Nov. 2015, by Chad Larrabee.
http://www.airbestpractices.com/technology/compressor-controls/managing-multiple-compressor-systems-utilizing-controls-improve-perfo

"An unmanaged control scheme for a bank of air compressors is a recipe for unnecessary consumption of power, as well as increased or unplanned maintenance. Controlling air compressors with only their on-board controllers can cause one or more of the following problems:

  • Too many compressors are running.
  • The wrong combination of compressors is running.
  • Pressure is higher than it needs to be."
