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...

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...

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...

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...

The purpose of this project is to perform laboratory and field tests of commercially available pool pumps and pool pump controllers designed to enable curtailment of pool pump loads in response to DR event (curtailment) or pricing signals. This work is a follow-up to prior studies that estimated...

Lab and field assessment of large quick service restaurant chain's new cheese melter. The existing cheese melters, consisting of two cavities, will be replaced by newer models that have one larger cavity. Existing cookie-cutter restaurants have two units for a total of four cavities. The new models...

Conveyor broilers are commercial food service appliances used in quick-service restaurants. Conveyor broilers apply heat to both the top and bottom of the food as it travels through the appliance on a steel conveyor belt. This project will validate savings claims for conveyor broilers at a major...
