| Rain barrel | Containers that collect and store roof runoff for later reuse. They can provide an alternative source of water for irrigation or toilet flushing, thus reducing the property’s potable water use while also mitigating stormwater runoff. Rain barrels typically hold about 60 gallons, and provide water for landscape irrigation. Because of their small size and potential to remain full, however, their impact on stormwater management is limited. Cisterns are typically larger, and may include pumps and filtration systems that allow them to be used to supplement gray water needs such as toilet flushing. Because of their size and ability to supplement gray water needs, they can be more effective for stormwater volume reduction than rain barrels. | View | None |

| Rapid cook oven | An oven that utilizes one or more non-traditional heat transfer technologies to cook food product significantly faster than would be possible using conventional (e.g., convection, conduction, radiant) heat transfer technologies. Heat transfer technologies that may be employed include microwave, quartz halogen, and high-velocity or impingement convection. | View | None |
| Rapid start | A rapid start ballast applies voltage and heats the cathodes simultaneously. It provides superior lamp life and more cycle life, but uses slightly more energy as the cathodes in each end of the lamp continue to consume heating power as the lamp operates. A dimming circuit can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled. | View | None |
