US DOE’s L-Prize Rewards Points for Zhaga Book 20 and D4i

US Department of Energy (DOE) has recently declared that L-Prize will reward points for data-rich, upgradeable luminaires based on Zhaga Book 20 and D4i.

L-prizeZhaga and the DALI Alliance will explain the details in a joint webinar on August 19.

“DALI-based luminaires align very well with the L-Prize requirements,” said Paul Drosihn, DALI Alliance General Manager. “In addition to D4i, DALI enables white-tunable capability, standardized dimming, energy reporting, occupancy sensing and many other features specifically referenced in the L-Prize rules.”

“Zhaga specifications offer solutions for smart city and building lighting that help manufacturers, specifiers and operators of lighting installations to embrace the next level of connected and sustainable lighting”, says Dee Denteneer, Secretary-General of the Zhaga Consortium.

Luminaires designed in compliance with D4i or Zhaga Book 20 will be rewarded with extra points during evaluation for the L-Prize, a lighting competition announced by the US Department of Energy (DOE) which has a prize fund of up to $12.2 million.

Zhaga Book 20 defines a smart interface between an indoor LED luminaire and a sensing/communication module and combines complementary specifications from the Zhaga Consortium with D4i specifications from the DALI Alliance.

The L-Prize encourages the design of commercial lighting systems with breakthrough energy efficiency, quality, functionality, and sustainability. Its scope includes the luminaires, sensors, control devices and interfaces that comprise a connected lighting system.

Luminaires submitted for the Concept Phase, which has a submission date of November 19, 2021, will be evaluated according to many topics including quality of light, connectivity, product life cycle and more.

One topic is the capability of the luminaire to have standardized power and data connections that enable advanced lighting sensors and other devices to be installed or upgraded, either at the time of installation or in the future.

One point will be awarded for luminaires/systems that include standardized power, data, and sensor capabilities in compliance with D4i or ANSI C137.4, while a further point will be awarded for luminaires that incorporate a standardized sensor port and power/data connections in compliance with Zhaga Book 20.
