Boiler Tune-Up Cuts J.H. Baxter’s Annual Energy Costs By An Estimated $21,100

Energy Trust Blog, Jan. 5, 2017.
https://blog.energytrust.org/boiler-tune-cuts-j-h-baxters-annual-energy-costs-estimated-21100

"A Kewanee steam boiler is the backbone of J.H. Baxter & Co.’s wood-treatment facility in Eugene [Oregon]. But over time, the boiler’s fire tubes built up a layer of soot that decreased efficiency. The solution was a simple boiler tune-up that boosted efficiency by 8.5 percent, saving more than 41,000 therms per year. Not only did the project cut the facility’s annual energy costs by an estimated $21,100—90 percent of the cost of the tune-up was paid for through Energy Trust of Oregon’s 90 by 90 industrial operations and maintenance offer."

"Yerba Buena, a CleanGreen™ Certified cannabis grower in Hillsboro [Oregon], prides itself on being a good steward of the Earth. Part of the company’s commitment to energy conservation involves looking for ways to reduce energy use. In an industry known for energy intensity, Yerba Buena became one of the first recreational cannabis growers to take advantage of Energy Trust’s technical assistance and cash incentives when the company replaced T5 fluorescent lighting in its vegetative room with tubular LEDs."

Biomass Test Delayed at Boardman Coal Plant

"Portland General Electric had planned to conduct a full-day test burn at the plant using nothing but woody debris by the end of December. However, as winter weather had Oregonians cranking up the heat, PGE needed all resources on deck to keep up with the surge in electricity demand."

Energy Performance Comparison of Fans with Variable Speed Drives

ASHRAE Journal, Nov. 2016, by Armin Hauer.

"Highly efficient air systems require precise fan selection and a method to adjust the fan performance to the Load. Fan supplier applications engineers are experienced in identifying the most suitable fan type and fan size for a specified application, whether the fan duty is fixed or continuously variable. Manufacturer-certified performance and electrical power consumption data support competitive performance contracts and ensure minimum energy consumption."

Chiller Plant Optimization: Improving On Variable Primary Flow Chilled Water System Operation

Engineered Systems, Nov. 2016, by Mark Bandini, Ernie Brandusa, and Carlos Petty.
http://www.esmagazine.com/articles/98002-chiller-plant-optimization-improving-on-variable-primary-flow-chilled-water-system-operation

"The larger or more complex a cooling plant becomes, the more challenges to its efficiency it will face. When applied wisely, modern controls and equipment can rise to meet those challenges. Read up on active balancing, pump dynamic differential setpoint control, and more responsive tactics for when the worst thing you can do is just go with the flow."

"Production and sale of biochar at biomass-using plants can result in significant financial gains, but the industry is still working at building its myriad of potential markets."

Specifying HVAC Equipment in Critical Environments

The Construction Specifier, Dec. 2016, by Matt Strong.
https://www.constructionspecifier.com/specifying-hvac-equipment-in-critical-environments/

"Cleanrooms present unique design challenges because they must meet specific requirements that go beyond what is encountered in a typical commercial space. When specifying HVAC equipment in a critical environment such as a cleanroom, engineers must consider the key issues of air filtration, humidity control, and pressurization. While a specifying engineer may have experience with these issues in the context of a traditional commercial application, the considerations are substantially different in a cleanroom."
