ASHRAE, U.S. DoE sign renewed MoU agreement

ATLANTA, Georgia, 23 June 2022: ASHRAE and the U.S. Department of Energy’s (DoE) Office of Energy Efficiency and Renewable Energy (EERE) signed a renewed Memorandum of Understanding (MoU), agreeing to further their long-term relationship, ASHRAE said through a Press release.

Mick Schwedler, 2021-22 ASHRAE President and Kelly Speakes-Backman, DOE Principal Deputy Assistant Secretary, signed the MoU in early June. According to ASHRAE, the agreement defines parameters on how ASHRAE and the DOE will collaborate more closely to continue to advance and promote mutual interests.

“With ASHRAE’s focus on building decarbonization and resilience, we are pleased to continue our partnership with the Department of Energy, as we share our knowledge base in the built-environment on a larger scale and work towards a more sustainable world,” Schwedler said.

ASHRAE and DOE seek to work cooperatively on the following:

• Advance decarbonization of the building sector by increasing the energy efficiency and reducing the carbon footprint of buildings beginning with the construction phase throughout the building’s life, including operation and maintenance;
• Increase the grid-interactivity of buildings by advancing grid-flexibility, flexible energy storage, and renewables integration into buildings;
• Promote more resilient, efficient buildings through the adoption of advanced building standards and codes, including supporting innovative code approaches in the model code development, building performance standards, and zero energy codes;
• Increase compliance with the latest building energy codes by supporting States in understanding the latest codes;
• Improve building resiliency and keeping occupants safe;
• Develop the workforce of the HVACR and associated sectors, including through increasing diversity and advancing training to support decarbonization; and
• Improve overall building performance, including for occupants’ health and well-being.

Armstrong launches medium-range line of permanent magnet pumps

LAS VEGAS, Nevada, 31 January 2022: Armstrong Fluid Technology introduced a new size range of design envelope permanent magnet pumps that are engineered to deliver 20% lower operating costs than variable-speed pumps with standard induction motors.

Making the announcement through a Press release, Armstrong said the new pumps are available with motors ranging from 15 hp to 50 hp, and operate at NEMA ultra-premium efficiency levels that exceed the efficiency targets of the US Department of Energy and the European Union.

“Better performance at higher RPMs means that in some cases, a smaller design envelope permanent magnet pump can deliver the same flow and pressure as a larger, more expensive competing model,” said David Lee, Offering Manager, Armstrong Fluid Technology. “These new pumps also feature smaller dimensions and are less expensive to purchase and install, because permanent magnet motors offer a substantial reduction in both size and weight.”

According to Armstrong, beyond the motor efficiency, a number of additional design innovations make the new design envelope pumps more energy-efficient and cost effective…

• Armstrong’s patented Parallel Sensorless Control stages multiple pumps and regulates output for best efficiency across the entire pump array, saving 10-30% in operating costs
• Adjustable design points and setpoint, based on the actual on-site conditions
• A quadratic pressure control curve that provides more efficiency than a linear pressure control curve
• A constant-flow function for maintaining a desired flow rate in recirculation applications
• Advanced connectivity via Armstrong’s Pump Manager, a cloud-based performance tracking service, provides industry-leading analytics and insights along with alerts, alarms and data storage
