No-loss drains expel condensate from compressed air systems, with no associated loss of compressed air. They typically are installed at the compressor, air dryer, filter, storage tank, or at any low point in the piping where moisture might collect. No-loss drains open a valve only when signaled by...

Identify opportunities for energy efficiency in dairy farms. The focus is on alternative methods to fans and soakers to cool dairy cows. Cooling technologies investigated will include hydronic heat exchangers embedded beneath free stall beds and water source heat pumps. Other areas to be...

This assessment consisted of a side-by-side comparison of two otherwise nearly-identical milk chillers; one with a finned-tube air-cooled condenser with fan cycling on pressure switches, and the other system with a microchannel air-cooled condenser. The project incrementally assessed the...

Field assessment of contact toasters for quick service restaurant applications. New contact toasters will replace two baseline units: one toaster for sourdough buns and one for regular buns. The new unit will eliminate the need for multiple heating elements. The expected outcome is validated energy...

Scaled field placement evaluates the electrical and thermal savings for DCKV when combined with building EMS systems in order to provide work-paper updates and inform new measures. Further evaluates opportunities for chains and SMBs using a tiered pricing...

This study investigates the demand response (DR) capability and potential of a controller which can lower the speed of variable speed pool pumps. The vast majority of incumbent pool pumps are single speed and can only be turned off for DR measures. Variable speed pool pumps have the ability to...

This project evaluated 10 water systems in the PG&E service territory to determine the amount of energy embedded in water supplies, perform leak audit surveys, review the effectiveness of previous leak remediation efforts (including estimation of the cost and types of leaks fixed), and estimate...

Cook and Hold ovens are commercial kitchen equipment used to cook food product at low temperatures, followed by a holding period at a specified temperature. Currently, no ASTM standard test procedure exists for cook and hold ovens. A standard has been drafted but needs to be vetted in a laboratory...

Lab testing was conducted to evaluate the efficiency at various loads for PMAC motors at the 3 and 5 HP sizes compared with Premium Efficiency Induction Motor (PEIM) technology. Lab testing found efficiency increases to be between 2% and 24% for the 3 HP motor and 4% to 24% for the 5 HP motor,...

This project aims to evaluate the potential for customers with water pumping equipment to participate in an Ancillary Services DR...
