At the July RTF meeting the Forum reviewed proposals for three new measures. First, the forum reviewed a proposed new measure for residential faucet aerators, a plumbing device attached to the tip of a faucet, likely in a home’s bathroom or kitchen, which restricts the volume of water that flows out. This technology saves energy by reducing overall water usage, vicariously reducing hot water usage, leading to less energy needed for water heating in a home. The RTF voted to allocate resource to developing a UES measure for this technology.
Next, the RTF reviewed a new measure proposal for Low Elevation Spray Application (LESA) for agricultural irrigation. This measure entails lowering the height of spray irrigation nozzles to improve irrigation efficiency and lower the necessary operating pressure for irrigation pump systems. The RTF approved the allocation of resource for this measure as well, and is slated to review a proposal sometime next year.
Lastly, the RTF considered its potential role in the realm of Strategic Energy Management (SEM). SEM is the optimization and integration of best practices of system analysis, equipment improvements, and operational improvements into a sustaining energy program across an entire industrial or commercial facility. The generalizable or uniform energy savings associated with SEM are difficult to estimate, as these projects are often tailored to an individual facility or organization. The RTF voted to allocate resource to conduct a scoping exercise in this space, to develop recommendations of what the RTF’s role might be in supporting utility program planning and evaluation for SEM/whole facility programs.
