The Hybrid Lighting Partnership

A broad-based public-private alliance continues to work together for the purpose of commercializing HSL. In addition to ORNL, the Hybrid Lighting Partnership includes members such as the Tennessee Valley Authority (TVA), Wal-Mart Stores, Inc., the Sacramento Municipal Utility District (SMUD), JX Crystals, 3M, Array Technologies, Sunlight Direct, several prominent universities, and other national labs. In 2006, the partnership will continue to carry out the multi-disciplinary research and development needed to make HSL a viable commercial technology.

Mission Statement

The Partnership's mission is to develop and deploy hybrid lighting systems worldwide early in the 21st century.  In the United States by 2020 we will provide:

  • annual energy savings of over 30 billion KWh's (> 0.3 Quads),

  • annual reductions in carbon emissions of greater than 5 MtC, and 

  • total economic benefits exceeding $5 billion.

The Partnership will improve the quality of life of people everywhere by providing more efficient and affordable solar energy, cleaner air, lower utility bills during peak demand periods, and a healthier, more productive work environment.

Hybrid Lighting Value Propositions

  • architectural convenience and flexibility
  • fewer and smaller roof penetrations
  • better control and distribution of sunlight
  • less glare and heat gain
    improved efficiency

Independent assessments predict that hybrid lighting will become the preferred method of bringing sunlight inside buildings in the 21st Century.

The Sun
The ultimate renewable energy source 

The Problem
Electric lighting is the single largest consumer of electricity in commercial buildings although sunlight is often available.

The Solution
Hybrid lighting solves this problem by delivering the benefits of sunlight directly to where we work - when we need it most.

Hybrid lighting is expected to be ten times more efficient than photovoltaics when used for lighting the interior of buildings.

Rationale for Partnership

There are several reasons why the Hybrid Lighting Partnership is a needed national lighting R&D initiative.

  • Lighting consumes large amounts of nonrenewable energy

    Today, lighting in U.S. residential and commercial buildings consumes close to 5 quadrillion BTUs of primary energy and one-fifth of all electricity. In commercial buildings, one-quarter of all energy demand is for lighting. With a forecasted doubling of commercial floor space by the year 2020 comes an urgent and growing need to find more efficient ways of lighting our nation's buildings.

  • Hybrid lighting is a logical technology pathway

    For this emerging pathway, no focused national program with widespread industry involvement exists. The Hybrid Lighting Partnership fills this void.  Several technology pathways exist to reduce lighting energy consumption in buildings. Three of the primary pathways include: 1) increasing the luminous efficacy of electric lamps/luminaires, 2) the development of intelligent (or adaptive) control systems that better respond to occupant needs, and 3) the development of advanced daylighting systems that better leverage available daylight, penetrate it deeper into buildings, and do so in a way that it can be cost-effectively integrated with electric lighting systems. For this third emerging pathway, no focused national program with widespread industry involvement exists. The Hybrid Lighting Partnership fills this void.
