This project had two primary goals: - To examine the performance characteristics of highly controlled lighting systems in a real office environment in terms of comparison to applicable codes, and -To evaluate the ability of the OTF Consortium framework to deliver a highly controlled solution...

Project SummaryThis assessment evaluates residential swimming pool cleaner energy use and efficiency.For more information, please contact the sponsoring...

Measure energy saved when a VSD is added to a car vacuum cleaning system at a full service car wash. VSD control allows the vacuum motor to change speed to match needed vacuum pressure and air...

Emergency and standby generators are common place for industries, institutions, hospitals, government agencies, schools and most commercial facilities that need emergency power. Most generators required block heaters to keep the engine block warm and ready to run within 15 - 30 seconds. Air Source...

Solar-powered circulator technology is an emerging technology that uses solar-powered equipment to drive a radial flow process that provides laminar circulation in water and wastewater systems such as water tanks and reservoirs, wastewater ponds and lagoons In addition, it can be used to improve...

Project SummaryLarge battery chargers are used with such products as forklifts, airport transport equipment, neighborhood electric vehicles and golf carts. Large battery chargers can be found in residential, commercial and industrial applications using both single phase and three phase power....

Project Summary:This assessment measured the energy savings of a Mechanical Vapor Recompression (MVR) evaporation system compared to a triple effect evaporation system for the production of tomato paste. The MVR system used 89% less natural gas per pound of water evaporated than the triple-effect...

Project Summary:The hot water load represents a significant portion of the gas consumption in a commercial food service operation, with an opportunity for gas savings. The objective of this field study was to investigate several water-heating system retro-commissioning measures and quantify their...

Traditionally hood exhaust in commercial kitchens are tied to a make-up air unit which balances building pressure during the kitchen operation. Generally, this hood is on at full speed for entire daily operation of the foodservice facility, which range from 18 to 24 hours per day. The concept of...

Project SummaryThe specific objective of the study was to analyze the energy consumption of the mechanical vapor recompression (MVR) milk evaporation system at Humboldt Creamery. The results of the MVR energy consumption rate are compared to the energy consumption of typical multi-effect...
